Huawei Mate X6 review
Displays
The Huawei Mate X6 has two screens - a cover display on the outside and a huge foldable one on the inside. Both use LTPO OLED panels with dynamic 1Hz-120Hz refresh rate, HDR Vivid support, and both have small perforations for the selfie cameras.
The cover screen has a 6.45-inch panel of 2,440 x 1,080 pixels, up to 2,500 nits of peak brightness and up to 300 Hz touch sampling rate. The display glass is quad-curved.
The inner screen is 7.93-inch with 2,240 x 2,440 pixels, 1B colors, up to 1,800 nits of peak brightness, and up to 240 Hz touch sampling rate.
We have completed our display measurements. The maximum manual brightness we captured was 633 nits on the cover screen and 683 nits on the foldable one. The maximum automatic brightness was 1,143 nits on the cover and 1,173 nits on the inner display.
The minimum brightness was 2.2 nits for the cover and 2.0 nits for the inner screen. Both screens offer 1440 Hz high-frequency PWM dimming.

Refresh rate handling
Both screens support dynamic refresh rate up to 120Hz, but the integrated refresh rate counter is not working properly, so we cannot confirm the exact steps it can offer. The available options in Settings are High (up to 120Hz with using the maximum possible RR), Standard (up to 60Hz), and Dynamic (up to 120Hz, but smart switching for longer battery life, uses 90Hz as well).
HDR video
The Mate X6's screens support HDR Vivid, which improves on HDR10 by using dynamic metadata to adjust brightness, contrast, and color levels on a scene-by-scene or frame-by-frame basis. In contrast, HDR10 uses static metadata, which is constant for the entire video. HDR Vivid is similar to Dolby Vision but is an open format unlike Dolby Vision.
In our testing, some apps detect the screens as HDR10 capable, but since the Mate X6 only supports Widevine L3 DRM, you will not get HDR or high-res streaming from any online service.
Battery life
The Mate X6 comes with a 5,110mAh Si/C battery. Unfortunately, the new hardware, together with the new battery and software, posted some uninspiring results.
The Mate X6 scored an Active Use Score of 8 hours and 56 minutes when using the foldable display. It got a below-average score in the call, web and gaming tests and a solid score in video streaming.
When running our battery life tests on the cover screen, we got a subpar Active Use Score of 11 hours and 26 minutes. The phone did well for video streaming and gaming but was below average regarding web browsing and call runtime.
Charging speed
The Huawei Mate X6 supports Huawei's 66W SuperCharge and 50W Wireless SuperCharge. The retail bundle contains a 66W power adapter and a proprietary 6A-rated USB cable.
The phone also supports reverse wireless charging up to 7.5W.
The bundled 66W power adapter and cable recharged 23% of the battery in just 5 minutes, 52% in 15 minutes, and we captured 83% of the battery charge at the 30-minute mark. A full charge took 50 minutes. While not the fastest charging possible, it ranks among the best in class.

The Mate X6 supports Smart Charge, which learns about your charging habits and drops the charging speed once it reaches 80%, only to complete the charging closer to your expected waking time if you are doing an overnight charging. Or you can set the maximum charge limit instead of slowing the charging speed - it could be 70%, 80%, 90% or 100%.
Speakers
The Huawei Mate X6 has two speakers - one on the top and another at the bottom. The stereo setup is symmetrical when the phone is in the closed position and asymmetrical when using it open.
The stereo setup scored a Good mark on our loudness test. The audio quality is good - there is a rich sound with well-presented frequencies across the board; it is just not that loud. While holding the phone and listening to music, you can feel the thump at the back of the X6 around the speaker next to the charging port.
Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.

I accidently entered my comment "Iphone isn't in the list" in this room. It belongs to other room "Top 5 phone... ". Sorry for being late to make correction.

It proofs the false advertisement sometime work best to boost sales. However, it is not as simply as it looks like. Most people have already been aware who is Samsung so far. What I meant here is a brand like Infinix should not do the same practice a...
