    You probably have a STL100-1 model, which is known for a battery calibration issue.. That means the phone doesn't read the precise battery percentage, so probably your 20% that the phone shuts down at is actually 0% or a bit more..

    There's threads here with different methods on how to fix the battery calibration issue. Try any of them

    You may try these
    1) when your phone is dead, remove sim card, memory card, and battery for an hour or two.
    2) try to charge it via PC
    3) Try different battery

    My ST100-3 does this almost everyday. I think I need a new battery!
