Anyone else having recent battery drain issues with an iPhone 3GS and iOS 5.0.1? All of a sudden today, the battery drained to 0 in 2 hours. I recharged at work, pulled it off the charger at 5:30, and at 7:20 it was down to 82%. By 9:10, it was down to 43%. I did a full backup and restore but I don't think it fixed the issue. It just started today. The Genius Bar was useless. Blamed it on me having too many tasks running. If so, then why didn't it happen last week when I updated?

I am not happy.

Edit: Oh and this is the work phone, so I'm limited in what I can do to fix it. I can't unlink my exchange account until I can talk to IT tomorrow.

This might be due to the OS 5 battery bug.

I have not had it happen, but people have been complaining about it off and on. I thought it was just a 4s issue, but I wonder if it is an OS 5 issue.

How long have you had the 3 GS? The battery might just be giving up the ghost.

MFNLaw I've had the issue with the 4S and turning off the automatic timezone determination in settings resolved it for me. It mysteriously came back recently and again that setting had been turned on, turning it off resolved the problem again. I also closed all my applications in case one of them was the culprit.

it's probably the location service constantly running, Maria. go to Settings->Location Services->Turn off everything that isn't necessary, like Maps.

I love 1password: it is available for windows, but I use it on the mac and iphone and I really dig it.

I share your love for this software :)

le n, the phone's only 3 months old. Work went with this over the 4 because it was free. @@

ehab, I turned of the automatic time zone determination 2 hours after I installed 5.0. It's been off ever since. I closed all my applications last night, and it's still going on.

tiggy, I don't think it is. I only have running what's necessary, and now I'm having an issue with my exchange emails not showing up on the iPhone until I click on them in Outlook.

Argh. So not happy.

hmmm...maybe it's just a lemon.

Erin, when are you looking to upgrade? Right now, T-Mobile has a lot of their 4G Android smartphones for free.

Not until March. I'm an early researcher. I know that comes as a shock...

But you like the Androids?

What is the difference between sleep and hibernate? I mean, I know that they're different, but...what is the purpose of each? In fact, what is the purpose of ever turning off the computer instead of hibernating?

When your computer is asleep, your session is kept in RAM, and it is still drawing power (although much less than when your computer is awake). If your battery dies completely (or you remove it), your computer's RAM will be wiped out and your session will be lost.

When your computer is hibernating, the contents of the computer's RAM is written out to disk, so the system can lose power completely, and your session can still be restored.

The drawback is that it takes time to write the RAM to disk (and read it back), while sleeping and waking up can be nearly instantaneous.
