Display
The Poco X6 features a 6.67-inch OLED screen of 1,220 x 2,712 pixels or 446ppi. It supports 120Hz refresh rate, Dolby Vision and HDR 10+, and 1,920 PWM dimming. A sheet of Gorilla Glass Victus handles the protection.
According to the official specifications, the screen has 1,200nits of High Maximum Brightness (that’s the sunlight mode) and up to 1,800nits of peak brightness.
We’ve completed our display test, and the numbers are in line with Poco’s official specs. We captured 531nits of maximum brightness when controlling the brightness slider manually.
When using the Auto Brightness mode or with the Sunlight Boost enabled, the screen can be much brighter – 1,339 nits to be specific.
The minimum brightness at point white was just 2.3 nits.
Color accuracy
The Poco X6 display supports DCI-P3 wide color space. The display color options offer three different color models – Vivid (default, DCI-P3), Saturated (DCI-P3 with saturation boost), and Standard (sRGB). You can fine-tune the color temperature for each mode.
There
is also a custom section, where you can select the color gamut (Original, P3, sRGB) and fine-tune colors, saturation, hue, contrast, and gamma.
The Vivid (default) option reproduces DCI-P3 faithfully, and we found it to be fairly accurate, excluding the slightly bluish-white and gray hues, but this is fixable by selecting a warmer color temperature.
The Original color option corresponds to sRGB and offers incredibly accurate rendering, including white and gray colors.
Color options
Refresh rate
The display supports up to 120Hz refresh rate, and there are two refresh modes – Custom
(choose between 120Hz or 60Hz refresh ceilings), and Default (automatic switching behavior).
The screen should support the fixed 30Hz, 60Hz, 90Hz and 120Hz steps.
The adaptive refresh rate works as expected – it drops down to 60Hz when the screen shows static content. All streaming apps are capped at 60Hz for UI and streaming, too.
And, of course, incompatible HFR apps such as the Camera app and Google Maps are always rendered at 60fps.
The only time we saw the screen use 30Hz was for the Always-on Display, which cannot be always-on all the time, but appears only for 10s.

HDR and streaming
The Poco X6 comes with Widevine L1 DRM support, and Full HD streaming with HDR10 and
Dolby Vision support is available across popular platforms, Netflix included.
Battery life
The Poco X6 comes with a 5,100mAh battery, a minor upgrade over the 5,000mAh battery inside the Poco X5.
In our Active Use Test, the Poco X6 posted average numbers across all on-screen tests.
Charging speed
The Poco X6 supports 67W fast charging and comes bundled with a 67W Xiaomi charger and cable.
The charger refills 47% of the Poco X6’s dead battery in 15 mins, 78% in 30 mins. A full charge took 48 minutes, which is nicely fast.
Optimized charging is available, an option that should prolong the lifespan of your battery.
Speakers
The Poco X6 relies on the traditional hybrid stereo speaker setup with a new twist. It has the
two pieces placed on its top and bottom sides behind dedicated grilles. The top speaker also acts as an earpiece, and that’s why it has another front-facing outlet.
As usual, the top speaker is quieter than the bottom one and focuses mostly on high frequencies. But since it has two outlets – the Poco X6 offers balanced audio output. The
speakers support Dolby Atmos enhancement, and it’s ON by default.
The Poco X6 scored a Good mark on our loudness test. The sound quality is very good – the vocals are great, the high frequencies are well presented, and there is some minor bass presence.
Turning OFF the Dolby Atmos makes a little difference – it offers a slightly richer but less balanced output.
