But it's useless because system shows same speed of battery decline, as if it is on the original battery.
Process is the same even if you connect internal battery to constant voltage source, thus preventing any discharge at all.
When misestimated charge value reaches 0, system goes to sleep mode.
I've already tried the BatteryCalibration app from the market.
I'm on rooted stock rom 4.4.2
Could you please give me an advice to fix battery the charge estimation algorithm or prevent sleep at least.
