Samsung Galaxy S2 Battery Drain

[Anonymous]

Hello

I've had an S2 for three months. Every ten days or so I experience very fast battery drain, with the battery lasting around eight hours with minimal use (sending/receiving a couple of text messages and making/receiving a couple of minutes' worth of phone calls).

I've tried deleting all the apps I'd downloaded and the problem wasn't fixed.

Is there a known issue with the S2? It's pretty useless to me as a phone when it regularly won't even last a full day at work with what I'd consider minimal use.

Any help would be appreciated.
Thanks

When I owned an S2 the biggest battery drain was Google Maps and location services as there was always an open service running in the background. If you don't use Google Maps, disable or uninstall it by going into Settings > Applications > find all and then Maps. From there it should give you the choice to disable or uninstall, normally one or the other depending if it's set up as a system app or user app.

Also go into Settings > Location services and disable sharing anonymous data with Google.

Some of this may not be 100% accurate as trying to remember off the top of my head but it should be very similar to get to those options.

You can install an application such as Juice Defender (Google Play Link) which not only help to reduce your overall battery consumption through various tweaks, it also lets you know which applications or services are using up your battery the most.

Android also comes with this kind of usage monitoring too - but it depends on which Android version you're using. You can try looking for it under Settings -> Battery, and if you can get to there - you should see the power usage by application.

Thanks for the replies and suggestions everyone.

I do use Google maps occasionally, but don't use the location service. I spoke with o2 the other day about the issue and they are sending me a new battery - I'm really not convinced that's the issue, but I'll give it a try.

Today the phone was nearly out of power after about 7 hours from being fully charged, with absolutely minimal use. The battery function is showing Android OS as having used 56% of the power.

It sounds like you are on old firmware. Have you checked for updates or done a factory reset recently?

On both stock Samsung firmware and custom with medium usage I used to get through a 14-15hr day with still 50-60% remaining so something's not right, it's good to see they've just offered to send out a battery though.

I'd recommend grabbing Better Battery Stats from the XDA thread here. It's a free version of the paid app but as the developer uses XDA to get testing and feedback from a free version has to be made available there. I've used it before and it will highlight all the apps and/or services that are using your battery most. You can then get logs from it which you can post in that same thread for help or post up here and will help others to help you

Ignore the %'s in the battery screen in the phone's settings as they rarely equal actual usage. It's meant to be relative to usage time but I've always had say 2 hours screen on and 30 mins Android OS however the Android OS was always a higher %. This was meant to have been a bug in ICS as was never the case with Gingerbread but can't remember that far back. Also when you hardly use your phone you can expect Android OS to be the majority of that usage because if nothing else is using the battery it is the only thing running therefore the highest %.
