I have a iphone 4s, i had 65% battery life when i was trying to respond to text message. When my phone completely shut off, i went to plug it in, it turned on and showed that i had 100% battery life but constantly would be searching and not pick up my service provider. Upon unplugging it, it would shut off and not turn unless i had it plugged in. Now when its on the charger it keeps shutting on and off. Please help.
iPhone 4S, iOS 8.1
HAve you tried resetting your phone?
IF resseting the phone does not work you can try restoring your phone i was told this week to restore as new iphone and do not use any back ups as you could be putting the problem back on to your phone and if that does not work you will have to contact an apple store And they will run diagnostics on your phone to find out what the problem is. Hope this helps you.
The two most likely possibilities are a failing battery (not unlikely in a 4 year old phone) or the battery gauge needs to be recalibrated.
Try recalibrating your battery gauge:
If the battery is not defective this should fix it.
Battery problem, please help!
