My phone will say that it's charged 100%, but when i take it off of the charger, it shuts itself off and will not turn on again untill i plug it back in. Upon doing so, it says my battery is completely dead, but when it turns back on, it says it's back at 100%. Please let me know if there is anything i can do to fix it, because i cant use my phone whatsoever unless it's plugged into a charger.
iPhone 4
iOS version? Jailbroken?
No, i havent jailbroken the phone, and i would check my iOS but i cant turn the phone on. As far as i know, though, i have the latest update for the iPhone 4
Restore the iOS using iTunes - first also retoring a backup and if needed without restoring a baciup.
If reststoring without using a backup doesn't help, there is a hardware problem (possibly a dying battery) that needs evaluation by Apple or an Apple authorized service provider.
Why does my iphone 4 turn off whenever its not charging?
