Should the iPhone be completely turned off to recharge the battery?
I'm really new so any help is appreciated. I've turned the iPhone completely off and tried to recharge without it recharging and I'm now at the 20% remaining and getting the red signal about the battery. I've tried recharging with the phone in a "sleep" mode and that doesn't seem to work either. Any suggestions are appreciated.
