Just came across this new battery app.There's lite and full version, free and for 1,99$. Look them up at google play. Just type in AutoLife - Battery Saver.
Was rather surprised that an app like this exists. It solves a huge problem for me since I often have problems switching in and out of wi-fi networks. (I'm on the road a lot)
Anyhow thought I would give you guys the heads up. Really cool app so if you are in the market for these sort of apps don't hesitate for one second.
