Battery meter going haywire


Android Expert
Lately my battery meters been acting strange. It would go up and down on it's own right in front of my eyes. Like say it would be at 50 then jump up to 52 while I'm using my phone. I would sometimes see it jump up or down by as much as 10 after a reboot.

No i don't have it plugged in during any of these times. Could it mean that my battery is soon to die? I just hope it lasts long enough until the arrival of the S3.
