Galaxy S3 Mini seems to be running out of battery really quickly. I checked the battery usage stats and it says that the Android OS is the main battery hogger, using 35 percent of the battery. Is this too much?
The only active widgets that I've got are the default whether one and a Google+ one, which I don't think should use a lot of battery.
Unfortunately you set the topic to a discussion not a question, so you don't get the option to select a solution.
I have changed that for you. You should now see the button on my posts.
Anyways, grats on figuring it out. I would recommend going to the play store, and downloading "ES Task Manager" it's a great app that lets you kill all background processes. It also lets you wipe the cache and a few other things. ES also has a file manager but you need root permissions to use it.
