Having a weird issue where my phone will display 40 or 50%, then suddenly drop to 5% and state that I need to plug it in. I have tried clearing the battery stats and the issue persists. It seems as though the phone is actually reading the battery status incorrectly. This is pure speculation, because it seems that the supposed 5% lasts for longer than I would assume.
What can I do to confirm the health of my battery and also ensure that the phone is reading the battery correctly?
Don't really want to try another ROM, so is there anything I can do short of buying a new battery to see if the problem persists?
