Iphone 4 battery woes

[Delarado]

Guys,

My iphone4 battery has suddenly gone to sh*t.

It was fine a couple of weeks ago, but last night I charged it to 100% before bed (midnight). It was flat by 8am. I've closed all my apps, switched it off and on again; I dont know what else to do? Is there any way to see whats taking up all the battery? I havent installed any new apps or anything at all recently, it just started all by itself...

Do you connect to an Exchange server for email?

There are some known issues that can cause the email function to pretty much constantly poll the server which burns through the battery in no time at all.

The battery could be failing as well of course, but if you want to try removing your email accounts then testing overnight again it might highlight a problem.

Make sure you have all the details needed to add the accounts back again before you delete them from the phone :)

I do connect to an exchange server, however I Always have done and in over two years this has never happened!

IS there any way to tell if the battery is failing?

[GIXERMAN]

have you got bluetooth and wifi on all the time?

You could try a quick pop into a Apple shop & speak to one of their 'Genius' people, always found them helpul when anything has gone awry

I had exactly the same problem and shared exactly the same disbelief that it could be the cause as I'd also had it running with the same Exchange server for ages.

However, removing the email account did fix the problem.

Hi,

I've just had exactly the same thing happen to me. Fortunately I had 7 days left in warranty.

I took it to the Apple shop and they tested the phone by seeing what the history of the battery was. They told me it was ok, which it clearly wasn't. Then they ran further tests and found although the battery said 100% actually the phone wouldn't let it charge to that state. Something to do with the dock inside!!!

They replaced the phone and all is now fine.:)
