Two days ago Chuwi released a new updated bios that fixes the powering off issue once lower than 40% battery. And the wifi disconnection issue (Never experienced this one myself). I’ve managed to get my Hi12 down to 3% without random any powering off so it would seem the issue is fixed. If I find any other issues I’ll be sure to report them as I continue to use the Hi12.
My unit has become my most used dual os tablet now thanks to the 3:2 Surface Pro 3 screen, dual boot and great battery life.
The bios fix is here
To flash it place the files on a bootage USB stick and then boot to it using F7 on boot. Make sure you have at least 80% battery life before doing this. Whatever you do, don’t power off your Hi12 and don’t do it on a low battery.
