I had this problem on my Galaxy S2 a few days ago, while listening to music and playing games after a while it shut down. Then when I start it again the battery is very low then shut down again with no reason. Uhm is there a virus in my phone, if any, how to remove it? Now everytime I am using it, even it is fully charged it still shutting down then the battery turns too low. Anyone? Pls. help

Could be you are needing a new battery. How old is the phone? And is it the original battery? How long are you playing games or listening to music?
