Up until now I have been pleased with my 3GS battery...but in the last couple of days it seems to be losing its charge more quickly with less use. At 5 pm tonight it was at 90%. I haven't used it since and now 3 3/4 hours later it is down to 60&. It is on my home network, and I haven't changed any of the settings. When I first got the phone I was playing several hours of games and the battery was lasting much longer. I generally plug it in to the computer each night for a sync and a charge and usually I get it down to 20 or 30% The only thing I can think of that might be the problem is the car charger...it has the option for a 'quick' charge...

Any hints or help?

    Try doing a full turn off using the top button, vs. Sleep.

    Next would be a Reset (hold both buttons for 10 sec or so).

    Final step would be to do a backup in iTunes (a sync) then a Restore.

    Things don't change for no reason and it seems unlikely this would be a hardware issue appearing sometime after buying the phone.

    Thanks. I did the turn off and back on after a while and after a full night's charge again it seems to be working fine again! Go figure! I will keep all of your suggestions in mind if this occurs again.

    Good! I find that with computers if I let them run long enough, or sleep long enough, without a full restart they can get discombobulated.

    Mine has just started doing this too. It also shut off as if it was out of juice when the battery meter read 36%. Not sure what caused it to suddenly start acting up this week, but will be doing a reset later tonight.

    Mine has been happy again once I did a reboot. I have not used it since noon today (it was 100% this morning) and it is still at 86% at 6:30. The other day you could practically watch the battery drain. Try the rebook (actually I turned it off for a while) and then recharge and reboot - it's like little gremlins get in there and you have to show them who's boss! LOL!!!
