The g heavy and 9. The Redmi 8 also supports Miracast for streaming video wirelessly to a Miracast-capable external monitor. Our review unit worked perfectly in this regard with our Sony Android TV. The device has a USB Type-C port for charging its 5, mAh battery, with the former being located on the bottom of the device. While the device cannot format microSD cards as internal storage, it supports the exFAT file system and has a dedicated microSD card slot.

The device runs on a base of Android 9. The global version of the device has Google services installed at the factory and, in addition to Chinese and English, supports multiple system languages including German. Please note that the Chinese version of the Redmi 8 does not come with Google services preinstalled. In practical terms, this means that the likes of the Google Play Store and Gmail are not there by default, with Xiaomi's in-house equivalents being preinstalled instead.
Adding these apps and services is easy enough, though. Third-party sellers like Trading Shenzhen have guides for doing so if you are interested. The Redmi 8 can only access a few LTE bands though, as is typical for a smartphone at this price. Specifically, the budget handset can only utilise 10 LTE bands, but this does not include the ever-increasingly used Band The Redmi 8 supports Bluetooth 4. The transfer speeds, which we measured with our Netgear Nighthawk AX12 reference router, are constant though, at least.
In order to measure the location accuracy of our test device in practice, we took it on a bike ride to compare the route it plotted against the results from a Garmin Edge bike computer.

There is about metres between the Redmi 8 and the Garmin at the end of a 6 km route, for reference. Overall, the deviations of the GPS module in our review unit are small. Looking closely reveals that the Redmi 8 is at least accurate enough for use when driving. Our review unit achieved a satellite fix with up to four metres accuracy indoors and six metres outdoors.

The call quality of the Redmi 8 is acceptable. The device reproduces voices well, with our call partner reporting that the microphone captured our voice cleanly too. Video-calls over Skype using the front-facing camera also worked without any problems during our tests, but the call quality suffers a bit because of the device's quiet microphone.
The device does not support Wi-Fi calling though, nor could we find it from within the main settings menu. The sensor also supports dual-pixel phase detection autofocus. Rounding off the camera setup is Google Lens support. The IMX captures plenty of details in daylight conditions and offers good image sharpness, at least in the middle of our test shots. Its colour accuracy is decent too, even if photos are often a little too reddish for our liking. However, low-light shots look significantly blurrier and lack the contrast that daylight shots offer.
The sensor struggles with exposing low-light scenes properly too. In short, the weaknesses of the IMX are particularly evident in low light. The highlight of the self-proclaimed "Selfie Champion" is its 8 MP front-facing camera. Choose a scene and navigate within the first image. One click changes the position on touchscreens.
One click on the zoomed-in image opens the original in a new window.
The first image shows the scaled photograph of the test device. We also subjected the primary camera sensor to further tests under controlled lighting conditions. Using ColorChecker Passport, we determined that the IMX reproduces colours solidly, while the sensor also does a good job at capturing colour gradients in our test chart. However, sharpness and contrast levels are only satisfactory in the middle of the picture of our test chart. The device also has 12 months manufacturer's warranty from the date of purchase. MIUI 11 offers onscreen buttons for navigating the Redmi 8 by default, but the OS also offers gesture control should you prefer to use that.
The capacitive touchscreen in our review unit is very sensitive and responds precisely right into the corners of the display. The glass top-layer has a pleasant finish to it too that is conducive to gliding one's finger across its surface. The Redmi 8 also has a fingerprint scanner, which Xiaomi has placed on the back of the device. The sensor is not that fast though, as is expected from an entry-level smartphone.
However, the sensor unlocks the device reliably and is much faster than those in devices like the Nokia 4. The Redmi 8 supports facial authentication too, although only using its front-facing camera. While not as secure as the fingerprint scanner, it recognised our face quickly and accurately. The Redmi 8 has a 6. The panel has a pixel density of PPI, which is good enough for everyday usage even if it is not that sharp.
Redmi Note 8 Pro: Design and Build
The display is comparatively bright, though. It should be noted that this only applies when the display is set to automatic brightness. If PWM was detected, an average of minimum: 5 - maximum: Hz was measured. The IPS panel also achieved a very good black value of 0. Accordingly, the panel has a high contrast ratio, which we measured at 2, APL50 reflected these values, too.
We also used a photo spectrometer and CalMAN software to assess the display's colour accuracy. These recorded a colour deviation from DeltaE reference colours of 2. These are comparatively low for a device at this price, while its colour temperature of 6, K is close to our ideal of 6, K. The Redmi 8 leaves a satisfactory impression outdoors, too. Its bright and contrast-rich panel ensures that content remains readable even outdoors in wintry conditions, but reflections from direct sunlight during the summer will likely obscure the display somewhat.
The IPS panel also has stable viewing angles, with there being no colour accuracy issues at regular viewing angles. There is some brightness drop-off at acute viewing angles, though. The UI does not, despite the display's low pixel density, always run smoothly. The device's limited performance shows when multitasking and loading games, with long waiting times being the rule here. Our review unit loads websites slowly too, while scrolling does not always remain smooth when the system is rendering complex content. Text, photos, and videos look sharp enough to keep these complaints at bay.
This particular panel can go as bright as nits by cranking the brightness slider all the way up, and with auto-brightness enabled, it maxes out at nits. I played a couple of HDR videos from YouTube on both the Redmi Note 8 Pro and the Redmi Note 7 side by side and the difference was immediately stark: videos and images looked a lot more vivid and life-like in the newer-generation phone whenever HDR was supported. The addition of HDR support is definitely nice, and even more so in this price range.
I also went ahead and downloaded Display Tester on my device in order to perform a couple of more tests, particularly in the matter of touch sensitivity, banding, contrast, and more. And the Redmi Note 8 Pro passes most of these tests with flying colors. When it comes to banding, contrast, and saturation, the Redmi Note 8 Pro emerges as a complete winner, coming out flawlessly in most areas. Colors are nice, vivid and accurate. The only aspect the device struggles with is with regards to black contrast, but they are still as good as blacks on an LCD can get given their technical capabilities.
But the Redmi Note line, in particular, has not featured a MediaTek-powered entry since the Redmi Note 4 with an Helio X20—which also received a wildly more popular Snapdragon powered model in certain regions. Additionally, MediaTek devices are often lacking in performance and other aspects, at least compared to their Qualcomm and Samsung competitors. And the fact that most cheap, crappy Chinese phones are powered by MediaTek SoCs has also tarnished their brand quite a bit in the eyes of end-users. The sole fact that the Redmi Note 8 Pro was powered by the Helio G90T was reason enough for a lot of people to immediately write out the phone from their list of options.

They have also released kernel sources for the phone, which means that modding and development should not be much of a problem compared to other MediaTek devices. And truth be told, I was actually very surprised by the way this phone performed, and in quite a pleasant way. My initial testing shows very promising results for the Redmi Note 8 Pro.
This metric only measures CPU performance and not much else. As expected, all of these devices are slightly ahead of the Snapdragon , while the Snapdragon carries the same overall score and is considerably ahead in multi-core score.

Work 2. I ran the test multiple times just in case it was a miscalculation error of sorts and they were all in the range of 10, Off this benchmark alone, we could suggest that the Redmi Note 8 Pro is about twice as better in graphical performance as the Redmi Note 7 Pro. Gaming in the Redmi Note 8 Pro is a decent enough experience. First off, I tried out Fortnite Mobile season X , which as many of you know by now is a surprisingly demanding game despite what it may look like initially.
With graphics settings set at High, though, the game actually manages to run fairly decently, staying at a constant 30fps most of the time. There were considerable frame drops here and there, particularly while jumping out of the bus as well as in busier areas of the map, but overall, nothing that really detracts from the overall experience or makes the game feel unplayable.
