Currently Being ModeratedJan 30, 2010 12:08 PM (in response to akarelin)Having the same problems! I just sent a text message with 67 characters and then sent it and my battery life went from 43% to 39%...How does that happen?? I switched from BlackBerry which has a great battery life. Come on Apple! Do something about this NOW!!!iPhone 3GS, iPhone OS 3.1.2
Currently Being ModeratedJan 31, 2010 4:30 AM (in response to brock13)Anyone out here has a problem where usage time = half of standby time? This is even after I turned off all services and put the iphone on airplane mode:
Mail: manual & all accounts deleted
3G: off (airplane mode)
Location services: Off
Push notification: Off
This is my replacement phone and it has the exact same problem as my first one . Wonder if this is a bad batch from the provider (Starhub in Singapore).iPhone OS 3.1.2
Currently Being ModeratedJan 31, 2010 11:47 AM (in response to CK13)I suspect that Apple isn't ignoring the problem as much as there is nothing they can do to solve it. That's the only explanation for a lack of a fix.Mac OS X (10.4.10)
Currently Being ModeratedJan 31, 2010 12:14 PM (in response to davidmintzer)Considering that most of us here are convinced that this is neither a hardware problem (including the battery itself) nor an app problem, that only leaves the OS. This is completely under the purview of Apple - no external considerations to worry about.
That the issue started with OS 3.0 gives Apple a good place to start investigations. That and they've been collecting user data on it for some time now. If it is unsolvable then it is time for them to drop back to OS 2.0 and start over or start working on OS 4.0 with this issue as top priority for resolution in the upgrade. It has been over six months and they haven't a clue? I really hope not.Intel iMac, Mac OS X (10.5.8), iPhone 3G OS 3.1.2

Currently Being ModeratedFeb 1, 2010 6:29 PM (in response to akarelin)my Iphone 3GS has got even worse battery lifetime.
With Push Off, Notifications Off, All Manual Fetch, 3G On, Wifi Off, Bluetooth Off, brightness at ~50%, the stats are:
Usage: 3hrs 15 min
Standby: 10hrs 10 min
Call time: 12 min
Current Battery: 8%
I had started the day with 100% battery charge, then barely used my iphone today except for checking emails about 8-10 times and listening to music about for 15 minutes!
With push on, the battery drains to 10% in 4-5 hours and the iPhone feels warm.
I have tried resetting all settings, resetting iPhone and restoring it back.
Has anybody experienced similar iPhone behavior? Any suggestions?

Currently Being ModeratedFeb 2, 2010 11:28 AM (in response to akarelin)A new iPhone update. But 3.1.3 not 3.2 (iPad OS). Says it fixes battery level reports.MacBook Pro 2.66 GHz Intel Core 2 Duo 4GB, Mac OS X (10.6.2)
Currently Being ModeratedFeb 2, 2010 11:34 AM (in response to gumsie)iPhone OS 3.1.3 is out....... supposedly it fixes the battery indicator problem..
i have my fingers crossed!!!!!!Other OS
Currently Being ModeratedFeb 3, 2010 8:09 AM (in response to kangjins2)I upgraded to 3.1.3 last night. So far I'm seeing some improvement. The phone has been on for 2 hours and instead of the normal rapid drop when I haven't even done anything, I'm at 97% after a few phone calls and texts! Promising.24" iMac, iPhone OS 3.1.3, iPhone 3GS
Currently Being ModeratedFeb 3, 2010 8:29 AM (in response to kangjins2)Installed 3.1.3 before going to bed. Fully charged the phone, then unplugged it and let it sit "idle" overnight (well, I do have "push" e-mail and notifications turned on).
I woke up this morning and check my iPhone 3GS and it had 84% battery life (~8 hours later). 3.1.3 is an improvement, but not a solution. (with 3.1.2 it would have had only about 64% after being idle for 8 hours)Orig, 3G + 3GS iPhones; 13" C2D MB; 24" C2D, 20" CD, 17" G4 + G3 iMacs; 3 iPods, iPhone OS 3.1.3, AEWB (100baseT)

you do realize that while you were sleeping the iphone is on 3g receiving signals all nite. assuming 8 hours 16% usage (email is in use) ~2% hour .... extrapolated 50 hours of 3g that is more than 2 daysmacbo0k, Mac OS X (10.6.1), 32GB 3Gs iPhone
Currently Being ModeratedFeb 3, 2010 8:46 AM (in response to Dizzy D)I don't know what you expect, but this sounds pretty **** good to me. Push and notifications are known to be battery killers. Someone claims Wifi is too, but I always have Wifi on and do not find it to be the case.
Do you actually expect it to be 95% after 8 hours with these on? Dream on.
There can be runaway processes that kill the battery, and I don't know how these get started, but they are rare for me. System Activity Monitor will show clearly when that occurs.
What improved things for me under 3.1.2 was some combination of the following:
1. Hard reboot, both buttons down.
2. Drain the battery fully from 100% by turning brightness up and all the battery killers on and playing music into headphones.
3. Full charge and beyond.
4. Restore as new user.
5. No push or notifications, manual everything for email.
Not all of you can run like this, but battery life was fine for me and seems better anecdotally under 3.1.3.MacBook Pro 17", iPhone OS 3.1.3
Currently Being ModeratedFeb 3, 2010 8:56 AM (in response to Arlak)Have you tried taking it to an Apple store and have it looked at? I did that and they replaced the phone due to a bad battery. Did this in November and have had no problems since then.MacBook Pro 13", Mac OS X (10.6.2)
Currently Being ModeratedFeb 3, 2010 3:19 PM (in response to Surachet)After updating to 3.1.3, my phone is doing the same thing, except that my usage time is always the same as my standby time. I've tried turning everything off as well as rebooting. It always shows both times as the same and the battery is draining rather quickly.
Prior to the update, I have had no problems like this.MacBook Pro, Mac OS X (10.6.2)
