My point still stands. Battery low? Stop. Using. The Device. Let it charge back up.

If you can't get a new phone, why not try to get a better battery? Definitely sounds like the battery itself is a problem and not the phone's 'management' of it. If you can't replace the battery, then oh well. Guess you gotta deal with it.
