Battery life

Walter199

Hi, after some days of plug and unplug battery to run SPFT to flash rom's or device, and run some test about microphone issue ( solve with welding and 35 euro's ) now the battery working bad,
the battery autonomy is very low the indicator say to 70% then suddenly turns off, then on again, and you see it at 2%.

Do you have a shorter battery life as well, or only the battery percentage indicator has become hectic?

I believe the indicator functions do bad, think the battery is good because lat night gone to sleep with 6% and morning after was 6%, or log in and out many times I ruined the connector.

Yesterday before sleep was at 70%, this morning immediately after woke up take it in my hand, on the screen and device shut down for end of battery.

You should install a battery management app like GSam Battery Monitor and monitor how the voltage of your battery is changing and compare it with the displayed percentages.

Try calibrate battery .

Calibration is not a miracle that can solve anything. If a phone shuts down from 70%, that might mean a serious malfunction of the battery or the power management electronics, not just an inaccurate calibration.

My phone battery temp is 49 C after i used 20 minutes,  Sometimes 52 C. And then, i put my umi into my  freezer about 5 min, after that, temperature is 19C. Lol. That is my used way.
