Battery

The Pocophone F1 has a 4000 mAh Li-Po battery.[7] The battery is 18W ″Quick Charge™ 3.0″ type developed by Qualcomm[12] where the port (USB Type-C port) is vastly superior to standard USB. It has 94 h of endurance as tested by GSMarena.[11]

Memory

Software

The Pocophone F1 runs on MIUI 11 based on Android 10. Since 4 March 2020, the software is upgradable to a stable version of Android 10.[13]

There is a very active software modding community for the Poco F1 and there are a huge variety of aftermarket custom ROMs or operating systems for the end user to install as they wish (after the user unlocks their bootloader).

Sales

Since it was announced in August 2018, it instantly became Xiaomi's bestseller with 700,000 units sold until 6 December 2018. It was the top rated smartphone of Q3 2018 in India .[14]

Issues

Early copies of the phone had screen bleeding issues. Some users of the international version of the phone reported issues related to an oversensitive screen.[15]

Upon release, the device came with Google's Widevine L3 certification, but with a software update released in February 2019, the phone promptly received L1 certification. This allowed users to playback DRM-protected content without any restrictions.[16]

The phone also allows HDR playback from the YouTube app even though the display does not have the feature, causing the videos to look washed out, grey and a bit darker compared to videos that aren't HDR.

The display on some units suffer from screen retention even after being replaced with a new and original display. The temporary solution some users found is to turn off the display for a few seconds to a minute and then turn it on again.

Media outlets described the device as a flagship smartphone at a bargain price.[22] Among the pros are a good camera and a strong battery.[7] The Pocophone F1 was the runner-up of MKBHD's blind smartphone camera test in 2018.[23] It also received a score of 91 from DxOMark, placing it in between the iPhone 8 and the Google Pixel.[24]
