I need a little help with a strange battery problem... or it could be a phone problem I suppose.
Over the past week this has happened three times on my stock Epic Touch running the latest Sprint public build, FI27, Android version 4.0.4
In each case, I was using it in some kind of high battery drain function... either watching a movie or running GPS software.
In two of the three cases, this was started right after unplugging the phone from the charger for the night, so I had a full charge,
but suddenly, without warning the phone just shuts off dead. No power down animation, no nothing... just goes cold black dead.
In each case, I know I've had about 60-75% battery left just before it died.
When I power up the phone, it beeps low battery, and say I have between 1-3% power left and eventually powers down from low battery.
However, if I pull out the battery and let it sit for a minute or two, then put it back in and restart, I've got battery power back again, at a slightly
reduced level. I happened to catch it in action this morning with a screen capture a little after 8am where you can see after the reboot, it reported
having about 55-56% before rapidly plunging down to 48-49% power remaining. Then the battery percentage began to grow over the next hour
rising up to about 56% by 9:30am before starting a very slow drain. It's now noon and I'm still got 50% remaining according to the meter.
Any idea what is going on? Is my battery going bad, or is this some kind of new bug from the FI27 build?
