Hey there, I'm having the same problem. My Xperia Acro S suddenly drops its battery to 1% from 59%. Then it shuts down automatically. After that, I turned it on again, and after 20-30seconds, then phone would shut down again. My phone also became super hot! Have you solved your problem? I've been searching for solutions for days! If you solved it, please share it. Sorry for my bad english.
