Ok so I looked and I looked for a couple of days trying to get rid of the freaking battery notficications. I mean I can see my battery bar with magic button and it seems as if after I get one 5 secs later another one would pop up while Im trying to do something and this was very very annoying. So I decided to start looking into how to turn off/change the settings....but to my surprise I never found a setting. So I got to playing around and found a fix. Install the .cab attached and now in ur sounds and notifications menu, you now have a Battery settings which u can change the options. The icon will still pop up on the task bar but no more annoying message popping up and getting in the way. Maybe some of yall feel like me so I decided to post this.

Edit: pulled the .cab for further testing...it worked for awhile but for some reason stopped....I'm looking into it.
