Well, i recently got my iphone replaced, and got a fresh new one (refurb imo). And, first day, it was fine, but after 2 days or so, i noticed the battery isnt really accurate. I could charge it, let it charge overnight, and it would go from maybe 100% to 89% or so within 5 minutes. Dont think its a battery issue, since it sometimes freezes on certain percentages, and it still lasts me all day. Any ideas as to what should be done, and as to weather or not im going back to the apple store for a third time in one week ?.? P.S. Updated to 3.1.2, not jail broken, and using the battery meter as jailbreak leftover. Thanks in advance for help.
