Hi there!
I recently updated my iPhone 3GS from OS 3.1.2 to 3.1.3.
I've experienced some bugs with this update. I will try to explain everything sience my other phones camera can't capture good pictures to show the problem.
Here we go:
First I power up my iPhone. Then when it starts up the battery percentage shows me that the battery has 67 percent left. Now comes the bug. After some seconds the battery percentage meter CHANGES to 78 percent. This has never happend before I updated. I am very happy with my iPhone 3GS and I feel pretty disapointed with this update.
I find this highly unacceptable sience it has basicly ruined the user experience because I can no longer tell how much power my battery has left in percent.
I hope that Apple or someone reading this topic can help me with this problem.
Also if i restore my iPhone 3GS, will it delete all my apps and saved data from the apps like high scores from the game "Doodle Jump"?

    Recalibrate the battery gauge by running the battery all the way down until the phone shuts off, then charge until full (preferably 4 hours).

    I just noticed something similar, my battery was down to 23%, 2 minutes later it reads 44%, another 2 minutes later down to 41% with nothing running..., what the heck is going on here? I haven't had an issue with battery levels before, I'll keep my eye on it.

    Upgraded my 3GS yesterday from 3.1.2 to 3.1.3. It now runs warm and drained the battery from 100% to completely dead inside of 5-6 hours yesterday and it was doing absolutely nothing. I charged it this morning to 100% and unplugged it at about 11am. It is now 2:42pm and the battery is showing 67% !! It's done nothing all day except sit on my desk and buzz once in a while when an email comes in.

    Nice going Apple.

    Exactly the same thing has happened to me. I upgraded the day before yesterday and I've had a very rapid power discharge since then.

    For instance, mine was fully charged at noon today and is now down to 57% three hours later, with almost no use.

    I am having the same problem since installing the new OS 3.1.3 - I immediately literally saw my battery life draining away - the phone now lasts about *4 hours* without any phone call/wifi/BT use at all! I have done all the things suggested above and the phone still drains within 4 hours.
    Can I get the previous OS 3.1.2 back? This is disastrous as I travel a lot and the phone is now *completely unreliable*.

    recalibrating the battery a couple times might be necessary. Leave everything possible on to drain the battery. If it's still a problem with the battery % jumping, you might want to look into reinstalling the OS?

    I will wait untill next week to update to 3.1.3 untill I read some better stories.

    You won't get a lot of better stories, because people with better stories rarely post messages in a support forum. But here's mine:

    I upgraded to 3.1.3 2 days ago. The upgrade took about 15 minutes, and since then my battery life is MUCH better. At this moment towards the end of the day (5 PM) my battery is showing 71%. Before 3.1.3 I would be down to 30-40% at this time of day, after removing it from overnight charge around 6 AM. I keep everything on all the time - location services, WiFi, 3G, BlueTooth, Push (Exchange), Notifications.

    From board activity, problems are very rare with 3.1.3. When 3.0 came out there were over 10,000 posts reporting problems within 2 days. In looking today there are only a few scattered ones.

    Hi All

    I just updated to 3.1.3 this morning. My phone is only 1 month old and had been working perfectly

    An hour ago it became unusually warm and the battery quickly ran down and died. I wasn't using the phone it was just in my pocket. I have made no calls today and have not been using any apps. I started the day with a full charge.

    Something is definitely not right here!

    It's likely that there is corrupted metadata in your email app. Try the following, in sequence, until the problem is resolved:

    1. Reboot the phone (hold Home and Sleep until the Apple logo appears; about 10 seconds).

    2. Delete the email account(s), reboot, add them back.

    3. Reset Network Settings in the Settings app and reboot.

    4. Restore the phone in iTunes.

    5. Restore again in iTunes, and this time set up as a new phone.

    You probably won't need to go beyond 3.

    No, if you actually read my post I said try them one at a time until the problem is resolved. So if the first one fixes it you are done.

    Just bought my 32gb 3gs on 30dec09. updated to 3.1.3 about 72 hours ago. since then i can't make it more than 4 hours after a 100% charge without finding my battery down to 30% or less. Doesn't matter what i'm doing browsing on wifi, standby, email, whatever! Was not experiencing this issue prior to upgrade. Also as reported by other users the phone gets very hot to the touch, even when just in standby. Very displeased with this issue! Making me wish I hadn't jumped ship from my trusty blackberry! i'd been elated with my iphone excuse up till now. Hope they get this fixed soon!

    Nobody here has answered your problem, I think it's a firmware problem I'm having the same problem you must send feedback, I just did, I doubt there is anything else we can do I think it's just the percentage icon that's the problem not the battery..
