    Hi.I'm using my Galaxy S2 for nearly two years.Now i have problems with battery.This problem came out a week ago.My battery goes from 38-45% to 1% just in a second.I think I should change my battery to new one.Am I right or is this problem more serious?

    If you have your original battery then yes buy a new one. My old electronics teacher told me the more you charge a battery the weaker the charge gets. So even if your battery has a "full" charge your battery can't hold the charge as long as it did from the start.

    Hope that makes sense.

    Also. It would be wise to only charge your phone under 10% to ensure a longer battery life.
