Go to a tech store and ask there. Sorry, I can't help you
My iPhone battery doesn't last four hours I use airplane mode brightness down and dont use it Will apple replace or fix this Began since the update and I practically can never use it I charge it to 100% before I go to bed & by morn its dead?
Make sure that bluetooth is turned off. That can severely drain your battery.
Yep, I'm think'n you might need a new battery. Batteries have a finite life expectancy. They will charge but they won't retain the charge...that is a sure sign that it's at the end or close to the end of the road.
