Hi. When I put my iPhone on the charger at night and go to bed, I wake up with 100% battery life. Now if I wake up in the middle of the night and keep it plugged in and check the screen then lock it again it discharges. I wake up to 97 or 92%.
Is there a reason? I've had it on my other iPhone as well!
I charge it all night. And I usually keep it right next to my bed and I wake up sometimes a little early to see what time it is And from that moment on it stops charging. I've tested it a few times over the past few days.
It's no big deal to me. As soon as I wake up for real I just unplug and plug again while I shower.
Can you guys try it. It only happens after being at 100% for many hours.
