Hi. 

After updating my phone to the recent ICS update, I've been having a problem with battery life. The day after I updated, I went from having 100% battery at 7 in the morning to being empty before lunch, with very little use on my part. The next day I fiddled around a bit, and I found it is a problem with the Mobile Network. When it is turned off, the battery life is perfectly fine. But when the mobile network is turned on, the battery drains at a rate of about 10% in half an hour. As far as I'm aware, nothing is downloading in the background, but if I leave the mobile network on for an hour or so, with the phone in idle, the phone physically heats up to a very high heat, and the battery would have dropped significantly. Does anyone know what the problem is and if there is anyway to fix it? It is very annoying to have to constantly turn the mobile network on and off, as before the update, it was always turned on.

Thanks.

Sounds more like a bug in an app that is running. I recommend backing up and doing a factory reset and then load everything back into it.

If that does not work, download JuiceDefender. It disables the networks when your not using the phone (turn off the screen).

Do te reset first though.

Accessing the Internet tends to use a fair bit of battery, so completely preventing your phone from accessing data by switching off Mobile networks will extend the battery usually 2 or 3 fold anyway.

I have heard a couple of reports of battery issues after upgrading to ICS. There are a couple of things you should try to rectify it:

• The first thing you should check is your sync settings. There have been a couple of reports that, after updating to ICS, the phones sync settings have been turned up to maximum (i.e. sync all the time). Having the sync settings turned up like this will use heaps more battery. You can check this through Settings > Accounts & sync, then select the individual account you want to check/change. Not all sync settings for all accounts can be changed.

• If your sync settings are all fine then, as will89 mentioned, a factory reset is the way to go. This will wipe everything on your phone and set it up again like it's just come out of the box. Make sure you back-up your data to your computer first though, because you will lose it all otherwise.

There is also a short video available on the Support section of our website that outlines a few ways to save battery. It might be a good idea to just have look at some of the tips, as they may lead you to the answer.

Please let me know how you go. If the issue still persists I would love to work with you to get to the bottom of it, and find a solution!

Cheers,

Nick

Hi Nick,

Thanks for your fast response. It turns out, indeed, it was the sync settings. I hadn't bothered to check, as before the update my sync seetings were all good and were at like 1 or two hours. But it appears that ICS had changed all my sync setting to 15 mintues, so obviously the continuos syncing was what was draining the battery.

Thanks for your help
