Insane battery life after 3.1 update

Did you restore in DFU mode (and if the answer is yes, are you sure you were really in DFU mode...many people get that wrong)? Also, did you set up as a new iPhone, or did you restore from a backup?

 

I've noticed bad battery life too, I don't know what it is. I'm going to let it run down to 0 this weekend to see if the meter is just wrong and there is more charge than it thinks.

 

scary

did you JailBreak your iPhone? .....ever

 

Are you sure you were in DFU mode? The screen was completely black?

 

Okay, is the battery meter accurate? Has it shut off yet?

 

If a DFU restore doesn't fix it, then I think the next step is the genius bar. Sounds like a hardware issue.

 

I would be bringing it to the Apple store if that happened to me. Best of luck with that.

 

Perhaps try downgrading to 3.0??

 

That would narrow it down to a hardware issue. It's possible that your battery just decided to fail during the update. Sounds pretty improbable, but still possible.

 

You cant do that with a 3GS can you? I could be mistaken but I thought you couldn't go back on 3GS.

 

I think it depends on whether you saved the backup file from itunes, since 3.1 wiped it. I have mine in a safe place. However, I've read what you are talking about, so I'm not totally sure you can use it. It would seem you can though.

NVM, to what I said, I didn't understand the new signing process for the 3GS.

 

If you get it back to 3.0, please tell me how, im using an iphone 3G, redownloaded the 3.0 firmware and tried to install it but all i got was errors, please tell me if you get it to work.

 

Seeing as everything recommended (everything I would also recommend) has failed.

My last resort or top recommendation at this point is to go to an Apple Store and state your case. Clearly, this has become a hardware issue now.

 

They are correct you can't do this with the 3GS because Apple stopped signing the 3.0 and 3.0.1 OS's for the 3GS when 3.1 came out. I would definitely take it to the Genius Bar because that is an insanely ridiculous battery life.

 

You still on 3.1?

 

I've seen similar poor battery performance ... both on a 3G and a 3GS. Something has changed, but I can't pinpoint what. It's pathetic performance right now.

 

your phone dropped from 49% to 10% in 26mins? time according to your clock....

dont even bother, take it to the apple store...something is clearly wrong...when people talk about bad battery life, they are talking more like a day or half a day with everything possible running...push on, fetching every few mins. You phone lost approx 40% in 26mins.....thats a shot battery.

If you DFU mode and restored it to a brand new phone and it continues, its gotta be replaced.

 

no doubt man, i went to my local apple store yesterday and swapped my phone out cause of a camera issues...

was a painless experience...however, right now its prob not a good time to go unless you have a appointment...they stop taking walk ins at about 7pm EST (2 hours prior to their closing time).

Grats on your soon to be new battery =) i think they will just replace the battery right there for you.
