iphone 3gs battery question

I have had my 3gs for less than a year now. But for about 5 days now the battery is draining really fast. I haven't changed any settings and it is jailbroken. It seems to drain 10-20% an hour on standby. If i goto bed with less than a full charge its dead in the morning. But it seems to last longer when in use...

One thing that did change but about a month ago, was my motherboard. Its a newer gigabyte and has 3X power. Maybe this isnt charging it right, to much amps and is or has killed the battery? Here is the http://www.gigabyte.com/MicroSite/185/on-off-charge.htm

Im thinking of restoring the thing, because draining while in standby is really bad.
 
The phone will not draw more amperage than it can handle. It could be that the ports were overvolting the phone, that would damage it.

Have you tried letting it run completely down and recharging it with the included charger?

Also, restoring is worth a try, it can help isolate a potential software issue.

If after restoring, the problem is still happening, consider taking it to an Apple store. The phone has a 1 year warranty and if nothing else they can run diagnostics on the battery to see whats what.

I googled around, but couldnt find any issues with the 3x usb's.

I have tried that.

I guess im gonna have to try a restore, when i can. Sucks that i can't use iphone as alarm.

Would they try to updated it to latest firmware? I dont have ATT either.

They might actually (update to latest firmware), probably by saying that unless they do so, they cannot rule out software issues.

If you do take it in, just see if you can have them test it regardless, maybe pick a random app and say that it doesn't work with the updated firmware.
 
my o.g. iphone 2g lasts longer than my iphone 4 lol. and the iphone 4 is like 2 months old tops.

treat your batteries right - always use the apple charger. it's spot on.
 
There are some applications out there that are not made well which have memory leaks and cause undue strain on the Iphone's battery life. IF I were you, I would restore it to factory settings with only the applications the phone originally came with.

yeah thats my next step, the restore and then restoring backup didnt change anything.
 
This happened to my 3Gs too, and it was a mystery what caused it. I noticed it a few weeks after I replaced the screen & digitizer. I ended up restoring it and re-jailbreaking it, and that didn't seem to help immediately, but after a week or so it just randomly seemed to go back to normal.

My theory is that I might have somehow physically damaged the battery, perhaps through overheating. I remember leaving the iPhone in a hot car all day long around the time I started noticing the battery problem. I know heat is bad for LiIon batteries, so I wonder if maybe the heat damaged the battery, and it took a while to "heal"? I don't know if that's even possible, but that's my theory.
 
well I just added a couple apps, runkeeper and no jailbrake so i could run tonight. But after about 2 hours of standby battery went from 90% to 90%, according to battery magic.

So it must be some thing on my previous setup. I mean less than 8 hours standby time. Battery magic says i should get 270 hours of standby.

Gmail push wouldnt use that much more would it?

Have you started running skype? Or other apps that are "working" in the background?

Well I think skype was/is the problem. But it has been fine since I updated to ios 4. Oh well guess shit changes iPhone battery drains at a rate of 10%/hr with skype now.
 
I have a 3GS I had same problem with battery but all I know about poor 3G network signals (1 bar) would kill battery real fast.
 
]WEll the mysterious battery drain has returned... restoring again. I found some comments on it on the iphone team blog below. At least I am a pro at restoring now... its major suckage though, from full batter to 30%, and only got about 6 hours last night. Anyone have any other info on this issue is it only for jailbrakers, 4.x? I never had this issue on 3.x, i might go back...

Hi, i got a iphone4 JB and unlocked with PwnageTool 4.1.2 for Mac and Ultrasn0w. All good, but i got a mayor battery problem. It goes from full charge to 15% overnight with no use at all and push off. Does anybody got a way to fix this?

I always set the phone up as new after I JB...Every time I just restore, I get total batter drain. Even on stock Software upgrade, no JB, battery drain.
I delete my backups and always start as new.
EDIT
Reading throught the posts, seems like others are having this issue, and have set thier phone up as new, so my advice is prob not worth 2 cents!

Tons of people having battery issues but there doesnt seem to be a clear cut solution. Try reinstalling ios and setting up as new phone. This worked for me temporarily but now I am back to battery drainage problems."
