[BUG]: Battery problems with SUP M3

[monuthebirb]

Version

2.0.0 (BETAv2) pre-release

Version type

uClibc (compatible)

Version hash

No response

Issue description

even though the battery is fully charged, the CFW is not detecting that and after 2 hours of charging, it still shows just one bar, which goes to zero in a matter of minutes, no charging animation as well.

after replacing the microSD card with MiyooCFW on it with the microSD it came with (it has the original SUP firmware on it), I can boot into the firmware it came with - and it clearly shows the battery as full. is there any way to reset the battery indicator in the CFW?

Steps to reproduce

1. Turn the device ON.
2. Look at the battery percentage. Congrats, its wrong.
3. Turn the device OFF.
4. Remove the SD card with MiyooCFW on it with the SD card the SUP M3 came with.
5. Turn the device ON.
6. Look at the battery percentage. It's full.

What device are you using?

Sup M3 v2

The "Charging" status has been added in MiyooCFW/gmenu2x@3bba839 so latest nightly (at least for M3).
For battery percentage indicator: first I suggest you grab another battery, then take a multimeter and observe battery voltage while compering with output value in /sys/devices/platform/soc/1c23400.battery/power_supply/miyoo-battery/voltage_now. If the multimeter values match what's in voltage_now file, then it may be your stock battery is drasticly loosing voltage due to low capacity or other cost-cutting factor (which original OS may mask to easy your pain of "bad spend money").
The Li-Ion batteries in Miyoo consoles are 3.7v so mid point between being flat and fully charged at 4.1v, which has been base for writing our frontend battery range points.
