iPhone 3GS OS 3.1.3 Battery percentage fail?

Does Apple test the OS updates before it goes out? Answer is NO

I am having the same issues... My battery is now reporting different levels especially when I turn it off and on...

From 25% to 7% with the warning that I have 10% battery left back up to 24%!

GO APPLE GO!

I always do a restore as new when I upgrade the firmware, and so far it has been a good experience. Have you tried the iPhone Configuration Utility? That software is incredible as it covers basically everything that iTunes can't handle! You define what (Email accounts, APN's, Wifi spots, etc.) you want to setup in profiles and then install the profiles on your iPhone within seconds.

I have done a full restore as a new iPhone on two iPhones... SAME ISSUE...

Do this test...

Look at your battery percentage on iPhone 3GS.

Turn your phone off and quickly turn it back on... Look at your battery.

It will increase/decrease without doing anything to it. It's Magical.

i'm with you in that its not likely the battery just all of a sudden went bad, but rather the way the phone is utilizing it. but its not just the percentage because my phone runs excessively hot to the touch after the update to 3.1.3 and will deplete the battery to the point of shutting itself down and will not turn back on until its been on charge for several minutes. not simply the gauge there, its dead! i'm growing increasingly frustrated. through the magic of it killing itself repeatedly throughout the day i've 'recalibrated' the battery (which i think is absurd at best for a lithium based battery) several times with no apparent increase in battery life. i attempted to back up all my files today in order to perform a restore as suggested above only to be prompted to accept the user agreement for os 3.1.3! **** no i won't agree with it! its the very thing that started all my headache! i want rid of it! please apple, fix your fix! you broke what was working fine! least for me, and it seems a number of other users. if i don't hear some decent news towards a solution i'm taking this $300 paperweight back to at&t tomorrow to see what they suggest (not holding my breath!)

it is fun isn't it, when i turn my iphone on the percentage jumps from the wrong % to the right percentage..stupid firmware always does something to my iphone, i have sent feedback hope you have mate

you must send feedback, apple dont read anything else but the feedback

Greetings,

No problems with my 3G, or my wife's 3GS, after 3.1.3. The battery life is as advertised, so I have no complaints, actually I didn't have any before, but after 3.1.3, if anything it reports a larger percentage at the end of my day, than before.

The update took no more that 15 minutes, or so. The apps all work, etc. Whenever I do an upgrade on a phone, or Mac computer, I run the usual maintenance routines. On the iPhone, I shut it completely off for a minute or so, not just put it to sleep - this clears out any resource hogging from lingering apps, if you have any. Then turn it on and do the update. Never had a problem.

I also have all of the services on, except Bluetooth - I have no need for it, as I have never answered a cell phone while driving - that's stupid. Pull over, take care of business, and move along. No call is worth the risk of an accident.

All works as it is supposed to.

Cheers,
M.

I just bought 2 3gs, 16 gig, updated to 3.1.3, and, now, when I power off then on, the battery percentage drops 17 percent, then after 2 seconds corrects itself also!! Its a bug in the 3.1.3 update! UGGGGG!

check your thread.

My phone was working great until 3.1.3. I did a FULL RESTORE after much aggravation and was very sad to lose a ton of settings i spent a ton of time on. Even with this, my phone runs VERY HOT and as someone else said it now gets 3 -4 hours battery life tops and runs down even when it's in standby. The meter is not that erratic, but it runs down very fast. i did a full discharge and more. very frustrating.

Yes, I am experiencing these same issues after the supposed fix.
Rapidly swinging battery percentages.
Did Apple TEST this update?

I'm sure they did, and it works fine on the 2 dozen 3G and 3GS phones in my office, as I'm sure it did on all of the phones they tested on internally and also the hundreds of outside beta testers. If you have a problem there are a few things you can try: Reboot, then if you still have a problem run the battery all the way down until the phone shuts off, then charge for 4 hours. In the very unlikely event that this doesn't fix it restore it as a new phone. And if you still have the problem take it to an Apple store for exchange, as you have a defective phone.

it is the firmware, just because you know of iphones that are not having the problem, doesn't mean we should take our iphones back for refurbs..it can actually be apple's firmware you know, oh and with all those iphones you know of sit and actually look at some 3gs's and turn them on and watch the % jump from lower % to the right one when u unlock it

its the firmware mate, don't listen to people telling you to goto an apple store as they will give you a refurb, i refuse to do that as i have only just got this iphone 3gs and i know its the firmware

I installed 3.1.3 on my phone in DFU mode. I had battery problems before as you can see from the HUGE 3.1 OS thread. I was happy that Apple finally provided a "FIX" for the battery..............BUT, My battery stamina got worse. Maybe even worse than 3.1.2.

I have an iPhone 3GS.

I miss 3.0.1 = best battery life ever!
