battery keep “discharging”, it probably done by max17047 chipset, wchich calculating current flow and estimate battery precentage. To prevent this, we can try short MAX17047 pin 5 (CSN) and 6 (CSP). Or use dumpsys like this:
/system/bin/dumpsys battery unplug
/system/bin/dumpsys battery set level 100
/system/bin/dumpsys battery set ac 1
