Why does my batteri drain fast all of a sudden?

[AC Question]

All of a sudden my battery Drains very fast (within 6 hours). Why?

What do your battery usage stats reveal? Also, have there been any recent changes to your signal, which might cause battery drain? Have you changed any of your phone settings?

It's very difficult to diagnose anything much with so little information, I'm afraid.

Or have you received an update? That can use a lot of battery for a few days to a week while the system is setting itself up.

Also check the battery itself. If it's removeable, put it on a flat table and flick a corner. If it spins, it's shot (it's bulging). If it's more than 6 months old and you regularly use it until the phone tells you to recharge it (which is between 5% and 10%) it could be on its last legs. If you discharge it until the phone shuts off regularly it definitely won't last long. The charge point for longest life is 50% (40% doesn't shorten the life much).
