Xiaomi redefines "flagship killer"



About five years ago, the word "affordable" would not be sung in the same lyrics as the words "flagship smartphone." But in today's smartphone market, both adjectives are often married under the umbrella term "affordable flagship." The phrase, quite explicitly, describes smartphones that look and look like a flagship, but cost much less than the classic flagship. The concept became a reality thanks to companies like OnePlus and Xiaomi. With the cross-over of affordable and premium features, these cheap flagships – just like the recently launched Redmi K20 Pro – have huge mass appeal and can attract more users than real premium devices.

Redmi has jumped into the premium segment, going beyond its pedigree on affordable and budget smartphones. Parent company Xiaomi has moved the ground with its aggressive marketing to reinforce the claims of the Redmi K20 Pro that it is an unbeatable leading premium flagship. While Xiaomi has launched several flagships over the years, its journey to radicalize premium smartphones began last year with its first Flagship Killer, the POCO F1. The Redmi K20 Pro carries this legacy with a 2.0 extension after the title.

Although it qualifies for Xiaomi's bloodline to be the flagship killer forward after POCO F1 remains controversial, Xiaomi has focused its stake on OnePlus in the fast-growing premium segment. Xiaomi is confident that the Redmi K20 Pro will destroy its competitor in the segment; thus, deciding to call the smartphone "Alpha Flagship." The Qualcomm Snapdragon 855 mobile platform is one of the main reasons for the Redmi K20 Pro to make it a powerful smartphone. But unlike the POCO F1, which was a knob on solid raw specifications tied to an unexpected polycarbonate design, the Redmi K20 Pro trumps this premise with a premium and stimulating glass design. This is complemented by a slit-less AMOLED display that hinders the symmetry of your device, a selfie camera closed by a pop-up mechanism, a triad camera at the rear with special optical zoom sensors and ultra-wide photography aside from the main 48MP shooter.

With this new and more premium product, Xiaomi is entering the territory, priced at 30,000 price points in India. The Redmi K20 Pro is charming and attractive, but if you want more glitter, there is a limited edition with a gold and diamond variant, which is nearly 15 times more expensive than the regular K20 Pro.

I have been using the Redmi K20 Pro as my primary device for almost a month now and have been forming opinions on aspects that may influence your decision to buy a smartphone.

Note: Xiaomi India has loaned us an 8GB / 256GB variant of the Redmi K20 Pro and 27W Turbo Charger for review.

In terms of specifications, the K20 Pro stands tall and sturdy, but is it breaking new ground for what it has to offer? We hope you have some idea by the end of this review. Let's start with the design of the smartphone first.

Design

Ever since the first teaser by Xiaomi, the design of the Redmi K20 and K20 Pro has been very intriguing. To enhance its first-class gameplay, the smartphone receives a glass sandwich design, along with Gorilla Glass 5 protection on both sides. Redmi is associated with the mesmerizing trend of 3D gradient of both the Flame Red and Glacier Blue variants, which makes the smartphone very attractive and distinctive. Even after looking at the patterns for literally several minutes in a row, I feel that I feel so much horror at the mesmerizing reflective surface.

The basic model shifts and changes with the incident light

In my first impressions of the Redmi K20 Pro, I talked about the basic layout of various design elements, so this section will be more critical and revolve around aspects that you should admire and be cautious about.

First of all, I love how the Redmi K20 Pro fits in the palm of my hand, especially since I don't have very big hands. The curvature of the rear window adds to the grip and makes the phone feel slightly lighter, though it weighs just over 190 grams. Redmi has added a thin and flexible plastic case to the box for those who prefer to conceal fragile phones. In terms of fragility, the design of a glass sandwich can upset some users, though the K20 Pro doesn't feel very slippery. For the durability of the glass design, there is a Gorilla Glass 5 on both sides and it is likely to delay consumers expecting the Redmi K20 Pro to introduce the latest version of the safety glass. By mistakenly tossing the smartphone into my pocket as my keys, I was able to create thick grooves both in the front and in the back. So, if you are already convinced about buying a Redmi K20 Pro, arrange a screen protector along with a case or leather for your smartphone.

The display of the Redmi K20 Pro, unlike its back, is not so curved and this is something I am rewarded with. Based on the comments we received in our first impressions, many people at first glance equate curved screens with a premium smartphone and this placement, in my understanding, is a side effect of Samsung retaining its premium portfolio of curved screens. With the OnePlus 7 Pro, the original killer brand – OnePlus – uses this trick to make the smartphone look more attractive. Personally, however, I prefer the flat display, as it not only facilitates the insertion of keys into the outer rows, but also facilitates the use of MIUI gestures, especially the back gesture, which involves swiping in at one end.

Redmi k20 pro xiaomi mi 9t review

The display measures 6.39 inches diagonally, and it's the same as the Mi MIX 3, which Max has found to be one of Xiaomi's premium devices. The Redmi K20 Pro has set out to travel to gain such a reputation, and the display helps it qualify as a premium device with its slim bezels all around, resulting in an attractive appearance.

With the Redmi K20 Pro, Xiaomi demonstrates its ability to make beautiful smartphones.

Although joining the same league as premium smartphones, the Redmi K20 Pro retains its headphone jack, and this careful step represents a compelling argument for consumers who have a long-term relationship with a particular pair of headphones. In an era where dongles are common, the presence of a 3.5mm jack remains controversial. It is commendable that Redmi managed to ram the headphone jack into the comfortable slim profile of the Redmi K20 Pro. However, this comes at the expense of an IR blaster, which unfortunately does not find room on this smartphone. I also came to increase my affinity for the lights on both sides of the popup selfie. This is especially useful when the selfie camera rises for incoming video calls or face identification.

However, during my use, I witnessed a selfie camera problem (thanks to a Twitter user F.T.L.O.G. for first reading this). Light bounces off the shiny metal area in front of the pop-up cavity of the camera, causing it to burn when there is a strong light source. In most cases, this burning is trivial, unless the smartphone is held at a certain angle to the light source but does not leave you with constant anxiety to avoid it. This is not unique to the Redmi K20 Pro and can be witnessed on devices including the Realme X, and a case that covers the reflective metal part should be able to remedy the problem. This video should help you understand the problem.

The overall design of the Redmi K20 Pro is quite compelling, especially because of the not-so-fine back design that can be anything from flames of flames to constantly shifting strips of clouds over Jupiter to fractal models. The design is compelling and competent enough to leave you in awe. The reflective metal surface surrounding the pop-up chamber remains of concern. You may want to use a clear case (my personal favorite is the Ringke Fusion-X for 99 1,199), which neither completely takes away from the beautiful back design nor causes the front camera to burn. The beautiful K20 Pro looks coupled with its solid design, let it gain your credibility as a smartphone, while the Gorilla Glass 5 gives some confidence in durability.


showing

Xiaomi's quest to build a memorial flagship, or at least a flagship killer, begins with its display selection in the Redmi K20 Pro. The smartphone uses an AMOLED display made by Samsung. The display has a peak brightness of 600 nits and supports ~ 104% of the NTSC color gamut. In particular, it's the same AMOLED panel as the flagship Xiaomi announced earlier this year – the Mi 9 – but the lack of a slot at the top allows the Redmi flagship to have a slightly larger screen-to-body ratio. Whether Xiaomi contributes to the Redmi K20 Pro as a successor to POCO F1 is something we will find out later this year, but the AMOLED display adds a new component to Xiaomi's leading killer DNA. The display comes with rounded corners and, unlike the POCO F1, Xiaomi this time complies with the symmetry. The display is folded by thin bezels along the four edges, including a light chin that is wider than the other three sides. Redmi uses a sophisticated monitor – the "Horizon" display for this screen on the back of easily avoidable frames.

In keeping with the AMOLED panels, the display of the Redmi K20 Pro has rich contrast and vibrant colors. The yellow hue masks the display, but this can be adjusted by using either the auto or high contrast options in the MIUI display settings. Like other devices running this Android system, you can change the color tones to suit yourself. This is not a Super AMOLED display and may feel limited in brightness compared to some other devices. However, the difference will only annoy you when the Redmi K20 Pro is placed side by side with another smartphone that has a Super AMOLED display.

With continuing concerns about the harmful effects that AMOLED displays can have due to low-atmosphere use, Redmi has added the DC Dimming mode to the K20 Pro. For the naked eye, DC Dimming increases the brightness slightly, but prevents the pulsation of light rays at low brightness levels from causing damage to your eyes. Curiously, at low brightness levels, the display brightness does not look the same across the panel and has visible columns of light and dark gray when using dark theme / mode applications. Dylan confirms that the problem is probable, since it hits almost all middle-class OLED panels.

Ribbons caused by uneven lighting under the panel. The problem is common with mid-range AMOLED displays and is not unique to the Redmi K20 Pro

As for the quality of this display, I ran some quick tests using the free version of the Braintrapp Display Tester app.

Display Tester
Display Tester

To begin with, the AMOLED panel does not show any evidence of burning, which sounds like a good offer to find. It supports multi-touch for up to 10 points at a time, and again this is standard but delightful. The Redmi K20 Pro comes with flying colors in the strip, contrast and saturation tests and looks just taut at the far end of the color gamut, ie. in too dark or too light colors in the strip test. In addition, the display is only a little short of perfect with respect to the contrast test. Frankly, you are not likely to notice these shortcomings unless you put this device next to a smartphone with a much superior display.

In particular, when two or more fingers rest on the screen, moving the third finger along a path parallel to an imaginary line causes the other two points to move slightly, and the layout video below should illustrate what I'm trying to say . The problem is known to affect other (non-super) AMOLED displays, so Xiaomi is not really to blame in this case. Having said that, I have not encountered any problems because of this, while playing strictly on the Redmi K20 Pro, especially in FPS games like PUBG Mobile and Shadowgun Legends.

However, the ghostly touch problem associated with the 3-finger screen gesture that annoys many POCO F1 users also continues on this device. Sure, disabling the gesture option is an ideal way to deal with this, but I would expect Xiaomi to fix the issue after almost a year of consumer agitation. Plus, it makes an effective gesture in MIUI useless. There is still no promise of a software fix for this bug, but I hope Xiaomi continues to receive user feedback.

Overall, while the Super AMOLED display will be highly regarded, the choice of AMOLED panel is based on the economy of the smartphone. Despite its lower brightness than Super AMOLED would offer, the readability of the Redmi K20 Pro's display remains unbeatable, even in strong indoor and outdoor light sources, unless it directly reflects the sun, making it easier to ignore. these imperfections.

Finally, devout developers in the XDA forums have created a way to beat the refresh rate of the Redmi K20 Pro to 75Hz, which is worth a try if you want better display performance. However, keep in mind the risks associated with such a move.


performance

The Redmi K20 Pro meets the expectations of a top-notch smartphone in terms of overall design and display, as well as showing the right set of flagship handsets. The Qualcomm Snapdragon 855 mobile platform, coupled with up to 8GB of RAM, is the primary driver behind the K20 Pro's motive. The octa-core of the mobile platform consists of eight 7 nm Kyro 485 cores, which are in three different clusters. These include one high-performance 2.84GHz core, three 2.42GHz cores, and four 1.8GHz high-performance cores. This setting is the same as the one we see on Xiaomi's earlier flagship this year – the Mi 9, which was hailed by Adam as "masterfully"Artist in his review. However, almost six months have passed since the launch of the Mi 9, and this has allowed many other companies to place their leading competitors in the segment.

Undoubtedly, the muscle strength that the Redmi K20 Pro shows is leading. Xiaomi says the major AI preloading optimizations in MIUI are learning about user preferences. Using machine learning, this algorithm can predict which application is likely to open and pre-load it microseconds before you do it. Undoubtedly, the Redmi K20 Pro never makes you yearn for more power, there is always plenty to offer. The review unit we have for review has 8GB RAM and 256GB, which is the most Xiaomi has to offer on this smartphone. Having been using the device for a month now, I have not encountered any stuttering or lagging accidents and the same can be expected with the 6GB RAM variant.

Undoubtedly, the Redmi K20 Pro never makes you yearn for more power, there is always plenty to offer.

Although the measurable performance of the Redmi K20 Pro is probably not going to be much different than the Mi 9, I put some of the usual synthetic indicators into perspective.

AnTuTu

Starting with AnTuTu first, the K20 Pro breaks the 350k mark and is approaching – albeit small – other smartphones shaking the same chipset. Despite the same configuration as the Mi 9, our review unit K20 Pro lags slightly by a noticeable margin of nearly 20,000 points. The chart below compares the AnTuTu rating of the K20 Pro with that of the Xiaomi Mi 9, Nubia Red Magic 3, OnePlus 7 Pro.

GeekBench

Moving on to GeekBench 4, one of the most direct and widely used synthetic indicators. It's always exciting to see how each device crosses a certain threshold, in which case the Redmi K20 Pro's kernel results exceed 10,000, which is nothing but an achievement for a smartphone that almost bends into the premium segment. In this test, the Redmi K20 Pro appears to be ahead of the Nubia Red Magic 3 and comes close to the OnePlus 7, but remains less than the Mi 9.

There are noticeable differences in the sequential results from the Geekbench of the K20 Pro, and they usually diminish with the heating of the smartphone, which means that there may be some thermal jamming in this case. Unlike the POCO F1, which had a liquid-based radiator, the K20 Pro comes with multiple layers of graphite around the heat dissipation motherboard. For a fair comparison, I use the average three results. Here's a comparison chart:

PCMark Work 2.0

In the process of gaining Redmi's Alpha performance, the next step was to compare estimates based on PCMark Work 2.0 performance metrics. PCMark Work 2.o measures the smartphone's capacity to perform routine tasks such as web browsing, photo and video editing, as well as opening, viewing, editing and saving documents using the Android API. Redmi K20 Pro в тези задачи понася бодър удар от OnePlus 7 и това вероятно ще се дължи на по-бързата технология за съхранение на последната. Ето как се справя Redmi K20 Pro в сравнение с OnePlus 7 по отношение на оценките на PCMark Work 2.0.

3D маркировка

Мобилната платформа Snapdragon 855 на K20 Pro се предлага с графичен процесор Adreno 640, който вероятно предлага 20% увеличение на производителността на графиката спрямо Adreno 630, интегриран в миналогодишния флагмански чипсет – Snapdragon 845. Докато работи с 3D маркировка, което е графично-интензивен бенчмарк, видях някои озадачаващи тенденции в работата на смартфона. Той не само се справя под повечето други смартфони със Snapdragon 855, но също така изостава от други устройства със Snapdragon 845, включително OnePlus 6T. Това е смущаващо, тъй като Xiaomi прекара доста време на стартиращото събитие в Индия, хвърляйки модни думи като "Vulkan", което е кросплатформен API, който позволява на тежки графики приложения – особено игри – вместо графичния драйвер да контролира графичния процесор за оптимално разпределение на графични нишки и памет на приложение.

Колкото и да е странно, K20 Pro не може да поддържа други устройства в тестове, използващи API – Vulkan и OpenGL. Това може да е така, защото единицата, с която разполагам, е предварително производство, но няма ясно обяснение за този фалш. Ето сравнителните резултати, които можете да проверите:

Пуснах GFXBench, което е друг показател за взискателните графични задачи и можех да наблюдавам подобна тенденция с по-ниски резултати от конкурентите във всеки от тестовете. Във всеки от тестовете, K20 Pro има най-ниската честота на кадрите в сравнение с OnePlus 7 и Red Magic 3. Разгледайте сравнението на оценките между Redmi K20 Pro, OnePlus 7 и Nubia Red Magic 3:

Бенчмарк за съхранение

Redmi K20 Pro се предлага с UFS 2.1 двулентово хранилище за NAND. Докато UFS 2.1 се разглежда като стандарт за множество устройства, OnePlus 7 води с най-новото UFS 3.0 хранилище, което го прави значително по-бърз при ежедневна употреба. Можем да намалим Redmi K20 Pro с известна слабост, тъй като тя има много повече на топката, отколкото OnePlus 7. Интересното е, че Idrees не намери съществена разлика в реалния живот, въпреки по-бързото съхранение в USF 3.0 по време на прегледа на OnePlus 7. Освен това, друга интригуваща тенденция в сравнение с UFS 3.0 устройства (за сега имаме само OnePlus 7 и 7 Pro) е, че докато последователните четене и запис, както и случайните скорости на четене са по-високи на тези устройства в сравнение с UFS 2.1 устройства, случайните скорости на запис са много по-ниски на устройствата OnePlus .

Скоростта на трансфер на вграденото хранилище, изчислена с Androbench, е следната:

игрален

Що се отнася до игрите, представянето на Redmi K20 Pro е толкова добро, колкото може да се получи. Както повечето случайни геймъри на смартфони, и аз копая FPS игри и K20 Pro борави с популярни заглавия като PUBG Mobile, Fortnite и ShadowGun Legends много добре. Предвид спецификациите, разбира се, не би трябвало да има никакво съмнение относно игровата производителност. По-ниската производителност на графичния процесор, която видяхме в показателите по-горе, може да е нещо за размишление за няколко секунди, но в реалния живот не съм изпитал никакво закъснение или спад на кадъра, докато играя всяка игра, която тествах на устройството при най-високите настройки. Например, PUBG Mobile работи с Ultra frame rate и HDR (след най-новата актуализация) с включено анти-псевдоним; въпреки че Fortnite не поддържа геймплей с 60 кадъра в секунда, който прави Mi 9, той работи без никакви пречки.

Някои от другите игри, които пусках на Redmi K20 Pro и също се радваха, включват Real Racing 3, F1 Mobile Racing, Hitman Sniper, Dragon Hills 2, Oddman, Monument Valley и др. Смартфонът също така получава опцията на Xiaomi Game Boost, която ви позволява избягвайте прекъсвания, повишавайте игровата производителност и графики по време на интензивни сесии.

Що се отнася до игрите, представянето на Redmi K20 Pro е толкова добро, колкото може да се получи.

За съжаление не успях да дам достъп до GameBench – както безплатната, така и Pro версията – за да мога да анализирам какво по-точно може да даде смартфонът по отношение на игрите. След няколко часа отстраняване на проблеми с търпеливите инженери от Gamebench, бях информиран, че изграждането на MIUI, работещо на устройството, няма липса на определени библиотеки, необходими за стартирането на инструмента за сравняване на игри. (Бъдещият ход на действие включва мигането на най-новата версия на MIUI на устройството K20 Pro, за да може тази статия да бъде актуализирана в бъдеще.) Въпреки че преинсталирането на системата трябва да помогне за изчистване на въздуха за способността на смартфона да посреща предизвикателства, свързани с графиката, аз съм напълно уверен в цялостната му игрална ефективност въз основа на практически опит.


sounds

Докато Redmi K20 Pro безспорно поставя забележителен концерт по отношение на своята производителност и мултимедийно изживяване, благодарение на впечатляващия хардуер – включително дисплея, вие също получавате богато изживяване по отношение на звуковите възможности на смартфона. Докато K20 Pro изтръгва злонамерения високоговорител за слушалки, който видяхме на POCO F1, първичният високоговорител е много силен и ясен. За времето, когато бях затворен в стена, бих предпочел да понижа звука. Възпроизвеждането на музика през един говорител също е добро, но е по-агресивно към по-високите честоти (както обикновено при високоговорителите). Докато Redmi не включва слушалки в кутията, можете да персонализирате качеството на звука, като използвате разнообразните ефекти на слушалки от настройката в MIUI.


Биометрични

Има два начина да отключите Redmi K20 Pro – скенерът за пръстови отпечатъци на дисплея и функциите за отключване на лицето. За да отключите смартфона с помощта на отключване на лице, изскачащата камера трябва да бъде изтеглена и това отнема почти секунда движение и поради тази причина предпочитам да използва скенера за пръстови отпечатъци. Това е оптичен скенер, както видяхме на повечето смартфони, работещи с технология за отпечатъци под дисплея (най-новите флагмани на Samsung имат ултразвукови скенери за пръстови отпечатъци). Както скенерът за пръстови отпечатъци, и автентичността на лицето са много надеждни и първият работи точно 95% от времето. Възможно е да има някои трептения, но това се дължи предимно на това, че палецът / пръстът не са подравнени със сензора.


Камера

По отношение на спецификациите и полезността на камерите, Redmi K20 Pro разполага с настройка, подобна (въпреки че не е точно идентична) с Xiaomi Mi 9. Настройката се състои от 48MP сензор Sony IMX586 за основната камера и обектива, който използва има отвор f / 1,75. Това е с помощта на 8-мегапикселов телефото сензор, който използва обектив с диафрагма f / 2.4 и поддържа 2-кратно увеличение. Освен тях, има 13MP широкоъгълен сензор, женен за f / 2.4 обектив, като част от настройката на задната камера и той заснема 125-градусово зрително поле. Задната камера също се предлага с лазер за автоматично фокусиране, двете видими точки, разположени между първичните и широкоъгълните сензори. Междувременно в изскачащата камера е включена 20MP селфи стрелка с обектив f / 2.2.

През времето, което прекарах с K20 Pro, се насладих на работата на камерата.

По време на първите си впечатления Redmi K20 Pro бях доста възхитен от работата на тази настройка на камерата и това настроение надделя почти месец, който прекарах със смартфона. Потребителският интерфейс на камерата е подобен на този, който видяхме на други смартфони Xiaomi и Redmi, работещи с MIUI. През времето, което прекарах с K20 Pro, се насладих на работата на камерата. Камерата, от една страна, се чувства многостранно и второ, е много надеждна. Има почти никакво изоставане на затвора и можете да вървите безпроблемно през различните режими. Освен фотография с до 48MP, смартфонът е способен на 4K видео запис при 60 кадъра в секунда, което очевидно е нещо, което любителите на видеографията ще се радват. Камерата също така поддържа опциите за откриване и оптимизиране на сцената на AI на Xiaomi, но изображенията, направени в моя преглед, са без опцията AI.

Освен това, Redmi K20 е оборудван и със същата настройка на камерата, така че можете да се чувствате свободни да използвате това като преглед на камерата на всяко от устройствата. За лесен анализ разделих производителността на камерата на K20 Pro в следните части:

Основна камера 12MP

Задействайки го с режим Photo на Redmi K20 Pro, 4-в-1 пиксела, поддържан от 48MP сензора на Sony, позволява на потребителите да правят изображения с ефективна резолюция 12MP. Тъй като те се формират чрез комбиниране на четири пиксела в едно, изображенията се оказват добре осветени и остри. По отношение на цветовете, изображенията, направени от Redmi K20 Pro, са много жизнени, но някои потребители може да ги намерят за по-наситени – или поне могат да изглеждат много наситени на AMOLED дисплея на смартфона. Това може да изисква известно редактиране, но като цяло изображенията могат да оправдаят изискванията на мнозинството потребители. Единственият интригуващ бит за камерата е, че изображенията обикновено имат ISO стойности над 100, което може да доведе до неочакван шум.

Redmi K20 Pro "width =" 1600 "височина =" 1200

12MP срещу 48MP

За разлика от Redmi Note 7 Pro, K20 Pro получава специален 48MP режим за изображения с висока разделителна способност. ISP на Snapdragon 855 SoC позволява много по-кратък процес на забавяне на Redmi K20 Pro от Note 7 Pro, въпреки един и същ сензор и на двете устройства. Както се очаква, изглежда, че 48MP кадрите на K20 Pro имат повече светлина и наситеност от тези, заснети в стандартния модел. Въпреки че традиционно се смята, че изображенията с по-висока разделителна способност имат повече детайли от 12MP, това зависи от количеството светлина. Ако изображенията с 48MP получат прилична атмосфера, изходните снимки всъщност имат повече детайли от 12MP, но при липса на адекватна светлина стигаме до повече шум и по-малко детайли.

Освен това, през нощта или при слабо осветление, 48MP изображенията имат по-висока ISO стойност и по този начин по-голям оптичен, както и цветен шум в изображенията. Разгледайте примерите по-долу.

[12MP vs 48MP]    Redmi K20 Pro "width =" 1600 "височина =" 1200

телеобектив

Възползвайки се от втората камера на Redmi K20 Pro, можете да правите снимки с 2X оптично увеличение. Телефото обективът на K20 Pro поддържа автоматично фокусиране и извежда изображения в 8MP резолюция. Докато телефото камерата заснема изображения с множество детайли, цветовете са видимо по-малко живи. Това може да създаде невярно впечатление, че изображенията са по-ярки, но всъщност това не е така.

[2x Telephoto]    Redmi K20 Pro "width =" 1600 "височина =" 1200

По-специално, смартфонът преминава към сензора Telephoto само когато има адекватна светлина, тъй като обективът на тази камера има по-малък размер на блендата f / 2.4. При сценарии с ниска осветеност първичният сензор цифрово увеличава до 2x, за да възпроизведе телефото ефекта. Въпреки че това може лесно да повлияе на детайлите, предпочитам да го използвам в определени сценарии, като например за правене на макро снимки, без всъщност да се затваря по темите.

[2x Digital zoom]    Redmi K20 Pro "width =" 1600 "височина =" 1200

Широкоъгълен

Широкоъгълният сензор 13MP Redmi K20 Pro може да заснеме 125 ° широко зрително поле. Поради по-малката бленда f / 2.4 в сравнение с основната камера, изображенията имат по-ниска експозиция и изостават от последната по отношение на детайлите. Практическите приложения на тази функция включват заснемане на по-широк пейзаж, както и заснемане на големи групи хора. Поради по-ниската осветеност изглежда, че широкоъгълните изображения имат по-добър контраст от тези, заснети с основната камера.

Нощен режим

Нощният мерник на Google постави еталон за цифрово подобрена нощна фотография, а флагманът Redmi следва примера на устройства, които разполагат с вграден нощен режим. Заедно с технологията за бининг на пиксели, камерата на Redmi K20 Pro може да заснеме доста количество детайли при сценарии с ниска осветеност. Освен че увеличава експозицията, нощният режим на K20 Pro също помага за подобряване на детайлите при слаба осветеност, но това идва за сметка на забележимо увеличение на ISO стойностите.

Портретен режим

Redmi K20 Pro не разполага със специален сензор за дълбочина, а телефотокамерата се използва за портрети или изображения с боке ефект. Изходът на тази функция е забележим, когато има достатъчно светлина, но смартфонът често може да пропусне, когато фонът и предният план имат съответстващи цветове. Смартфонът обаче може да не работи добре, ако се опитвате да заснемате портретни снимки с група хора, стоящи на различни разстояния.

Xiaomi’s MIUI does allow you to change the point of focus for bokeh shots and also allows you to change the depth of the effect to make it look as realistic as possible.

Самоснимки

The 20 MP camera on the Redmi K20 Pro comes across as capable and dependable. It captures a good amount of details, but it has a notable smoothening effect on the face. This is a fixed focus camera and because of the small f/2.2 aperture, the major focus is on getting the details of your face captured properly. In a lot of cases, this may result in the background being washed out, which is something that irks me. Considering the impressive performance of the rear camera, I do feel that the Redmi flagship deserved a better selfie camera.

The camera does perform explicitly well while taking portrait selfies. The edge detection is on point and you can choose from a variety of stage lighting effects available in MIUI.

Video

As mentioned previously, the Redmi K20 Pro is capable of capturing 4K videos at 60fps. This feature was highly demanded by the users of POCO F1 and its addition shows that Xiaomi actively listens to the feedback from its users. The quality of the 4K videos is on par with other devices in the range. Besides this, the smartphone also supports capturing stereo audio with the help of the primary as well as the secondary microphones. In spite of electronic image stabilization on the smartphone, videos do appear to get shaky.

Take a look at the 4K 60fps samples recorded using the K20 Pro.

The videos captured by the Redmi K20 Pro have good colors and details for a smartphone priced this much. From the Settings of the Camera app, users can choose between the H.264 and H.265 codecs for video recording.

Besides the primary camera, the telephoto sensor also supports video capturing at 4K with support for up to 60fps frame rate. However, EIS appears to be struggling to keep the video stable at 2X digital zoom.

The wide-angle lens also gets support for 4K video recording but the frame rate is limited to 30fps. Since the frame is zoomed out, the video appears to be fairly stable. Here’s a sample:

Besides 4K recording, the Redmi K20 Pro can also capture slow-motion videos at not just 120fps and 240fps but also 960fps. While the first two appear to be effectively slowing down the frame rate, the 960fps video is jittery and that may be because of extrapolation. While there’s no limitation on the time of recording 120fps and 240fps, the 960fps video is limited to 10 seconds. Since the video is slowed down to 32 times, it records less than a second of the real-life event and you have to be very precise to capture the right moment. Further, while you can trim the slowed down parts of the videos at 120fps and 240fps, there’s no trimming option in the 960fps video. Here are the samples of the Redmi K20 Pro’s slow-motion videos:

Sky replacement

Besides the horde of features, MIUI also brings the Sky Replacement filter in the MIUI Gallery using which you can change the sky in almost every well-lit picture. The feature intuitively senses the sky in the picture and lets you change the color and add or remove elements like rainbows, clouds, and sunset. Besides that, the feature also optimizes the overall color scheme of the image to make the other elements coherent with the sky. Here’s how the feature works:


Battery

The battery on the Redmi K20 Pro is among its key strengths. A 4,000mAh battery dwells inside the smartphone and it delivers stunning performance.

If you’re especially among the users who like to squeeze out the last drop of energy from your smartphones’ batteries, you will find the Redmi K20 Pro’s performance praiseworthy.

With heavy usage, I could easily get almost a day’s worth of use out of this battery per charge. What’s even more impressive is that I’ve been able to reap a daily screen-on-time of nearly 6 hours, with multiple gaming sessions included. If you’re especially among the users who like to squeeze out the last drop of energy from your smartphones’ batteries, you will find the Redmi K20 Pro’s performance praiseworthy.

When it comes to charging, the smartphone gets inherent support for Qualcomm’s Quick Charge 4+ with the Snapdragon 855. Additionally, the smartphone gets support for USB-PD which means it can be charged using any charger that supports that technology. Inside the box of the Redmi K20 Pro, you get an 18W charger that supports Quick Charge 3.0. This charger takes around 100 minutes to go from 10% to 90% and the charging eventually slows down on its way to 100%.

Since the smartphone supports charging at up to 27W, you can buy Xiaomi’s SonicCharger Adapter separately and this has the highest charging rate supported by the Redmi K20 Pro. Using this charger, the battery can be charged from 10% to 90% in approximately 75 minutes but you’ll be required to spare nearly 15-20 minutes more if you wish to tank it fully. This is because of the heating protection mechanism on the phone at higher battery levels. Notably, this charger also runs on the Quick Charge 3.0 protocol and you might experience some heating of the smartphone or the charging brick.

Furthermore, the support for USB-PD allows you to use charging solutions including the charger for a laptop. Using a 65W MacBook Pro charger takes only a few extra minutes above the standard 18W charger, it is safe to presume that it may be charging at approximately 15W. It can be a useful addition, especially when you’re traveling and don’t want to carry separate chargers for each device.

Lastly, I’ve not tried a Quick Charge 4+ charger with the smartphone and there’s no support for wireless charging on this device.


Connectivity

Offering great flexibility to its users who might be switching from a mid-range smartphone, the Redmi K20 Pro retains a headphone jack, which can be considered a luxury at this price point. Starting with the Mi 8, Xiaomi’s flagship series was deprived of a headphone jack, so it is refreshing to see that the Redmi K20 series accommodates one. Further, MIUI allows users to meddle with the system-wide equalizer settings by heading over to the “Headphones & audio effects” option in Settings.

Besides the headphone jack, the USB Type-C port on the smartphone also supports audio playback in addition to charging and data transfer. Further, Redmi has taken the liberty of removing the IR blaster from the K20 Pro, citing that many people are now inclined to using Wi-Fi or Bluetooth. While I don’t depend on the IR blaster for controlling devices wirelessly, your use case may be different. Further, while both the Chinese variants of the Redmi K20 and the Redmi K20 Pro have NFC, it is not present on the Indian unit and this may, perhaps, be because of the poor adoption of contactless payment methods in India.

The Redmi K20 Pro comes with dual-frequency GPS for better reception of signals and, thus, more accurate positioning. Compared to a conventional single-frequency GPS, which has an accuracy of 5 meters, the accuracy of dual GPS goes down to 0.1 meters, which is phenomenal. The feature has been instrumental in helping me navigate seamlessly on parallel roads and even while walking through the narrow and tight alleys of Delhi. This is something I would love to see on more devices in India.

In terms of network connectivity, the smartphone comes with LTE-Advanced which supports carrier aggregation in theory. In India, I tried using both the networks the support carrier aggregation – i.e. Airtel and Reliance Jio – in India and while the network status does indicate “4G+,” I did not see any real benefits of the feature in terms of network speed. Meanwhile, the K20 Pro supports dual-band Wi-FI and can also be used as a repeater, something we’ve been seeing on several Redmi devices for quite some time.


Conclusion

The Redmi K20 Pro portrays Xiaomi’s expertise in craftsmanship. Even though beauty is a slippery concept, the K20 Pro will appease your taste buds if you have the palate for stimulating high performance. The symmetric AMOLED display not only brings out rich colors in almost all forms of content but also helps you evade a notch, which I personally have not grown fond of yet. The Redmi K20 is an excellent device by all means and never fails to surprise in any sense. Even though the synthetic benchmarks show that it may not be on par with other devices such as the OnePlus 7 and the Xiaomi Mi 9, its relative affordability and the total of all the exciting features viz. its expansive display, a pop-up selfie camera, triple – and more importantly – useful cameras outweigh any concerns about lagging performance.

Redmi K20 Pro XDA Forums

In India, Xiaomi appears to be benefiting from the economy of scale. In the last five years of its presence in India, Xiaomi has surpassed Samsung, and now has four major manufacturing hubs in India. This also helps it keep the prices down compared to OnePlus which, as per the last piece of reporting on it, has been using sister company OPPO’s manufacturing plant to assemble its devices.

In the meantime, Xiaomi and Redmi have been working on crazy innovations like a 108MP cameras and 100W fast charging, and these are likely to shape the future of the Killer Flasghsip lineup by the two brands. Presently, the Redmi K20 Pro feels adept, equipped, and well prepared to not only slay competition but also pose a strong opposition to competitors. The Redmi K20 Pro is a good reason for OnePlus to be worried, not only in India and China but also in markets like Europe where the smartphone launches as Mi 9T Pro very soon.

Other color options available in India

In India, the 6GB/128GB variant of the Redmi K20 Pro can be bought for ₹27,999 (~$405) while the 8GB/256GB is available for ₹30,999 (~$450). You can also buy the 27W charger additionally for ₹999 (~$15). The smartphone is available for purchase via Flipkart and Mi.com and you would no longer have to wait for flash sales to buy one. The Xiaomi Redmi K20 Pro will also be launching as the Xiaomi Mi 9T Pro in the European region.
