3g_iphone_battert_deadAt first I thought I was alone, and that my iPhone 3GS was defective, but now it looks like battery complaints relating to iPhone OS 3.1 are far from isolated incidents. Apple is officially investigating the matter, according to The iPhone Blog, which is something the company generally only does if enough people crow loud and long enough.

My own experience is that the iPhone charges in far less time than it normally would, and then only lasts about 12 hours on standby with my average daily usage of around three hours talk/browsing/gaming time. That’s probably a full 12 hours of standby off of what it used to be able to handle post-updating.

The behavior seems to indicate that the iPhone isn’t recognizing or using the full capacity of the battery anymore. I’ve tried resetting the phone, but I haven’t done a full restore, since I’d rather wait and see what kind of fix Apple comes up with before I lose all my data and settings. Also, support forum posters indicate that doesn’t correct the problem.

Other problems include a sticky battery indicator, which sometimes also won’t go below 100 percent after a full charge, and a huge additional drain when using Push features. My temporary fixes include turning off Push altogether, and charging the phone whenever I’m near an accessible power outlet, since the battery indicator can no longer be trusted.

Hopefully, Apple can solve this quickly with a x.x.1 release, but until then, drop by the support forums and answer the questions Apple is asking about the problems to help expedite the process. You might even be able to get one of the “Battery Life Logging” profiles Apple is distributing to gauge the extent of the problems. If you’re experiencing similar issues, please share in the comments with specific details.

  1. This seemed to be initially occurring with 3.0 as well, but I found that a full cycling of the battery fixed it. Have you tried running the battery all the way down and then charging it completely without interruption?

  2. iPhone Software 3.1 Update – OSNN Forum Monday, September 21, 2009

  3. i always run my battery down as i invariably forget to charge it. But when i went to the genius bar last week for a macbook appointment i asked the genius about the dropped calls and battery life issues id had within the first week of 3.1and the guy said they have had a few people in and they’re just referring people to wait for 3.1.1 now because it seems to be a firmware issue rather than a handset issue, with a restore or not.

  4. My phone experience has gone down drastically since my update to 3.1. My phone has had trouble dialing out, it rarely can connect to the 3G network for data usage, the battery life is miserable. Glad I’m not alone!

  5. Ohhh, you are not alone. Since 3.1 I have rebooted my iPhone more times than I’ve rebooted in the previous 3 – 4 months. I never reboot this phone, now it’s a must. Locked up on me twice in 2 days, push the Home button and nothing happens. Wait 5 minutes and it’s back to normal. Calls just stop working. No apparent reason. That also happened to me twice since 3.1. Only found that a reboot fixes that. Really freaking annoying. But the fun one was the night it was at around 90% when I went to sleep. I forgot to plug it in, of which I’ve done plenty of times WITHOUT the same results. 6 hours later, it’s completely dead. Not enough battery to even show the low battery screen.

    Ridiculous that one update does this. I have had this phone for 10 months. Not one of these problems existed before 3.1.

    1. I have had the phone for the exact amount of time and you are explaining exactly what has happened to my iphone after the

  6. Started immediately after the upgrade, sudden black screens, slow response when opening apps, now crashes multiple times per week vs almost never, much less battery life, clearly is 3.1 sw or firmware related, first real problems after 18 mos of ownership.

  7. And for this you have the honor of paying AT&T $80 per month, minimum. Nice!

  8. I know this would be an embarrassment for Apple, but I sure would be a lot happier if they’d let me roll back to 3.0.1 until they get 3.1.1 out. Right now this upgrade is pretty hard to defend.

    1. you should be able to. just find the ipsw for 3.0.1 on the interwebs and restore.

  9. Maybe if Apple would easily allow people to modify the OS a bit more, some brilliant developer could develop a wiz bang way to cure the battery life issue. Just jailbreak it and give it to the open source community to solve.

  10. Battery draining much faster. Also, I’ve had several text messages where the progress indicator stops just before the end — then I get that exclamation mark telling me the text wasn’t delivered. Turning the phone off then on again did the trick with the text problem, but I did that just yesterday, so how long it stays fixed, I don’t know.
