Why My Iphone Battery Is Not Charging More Than 80. You either set it to max of 80 in the power manager options you can do that to try to keep battery life longer or battery is bad. Your iPhone might get slightly warmer while it charges.
Your iPhone will charge again when the temperature drops. While continuing to hold the OnOff button press and hold the volume down button on the left side of your iPhone. If your cell battery runs to dead it ages the battery much faster than charging above 80.
Even after being on a Wall Charger for several days the battery remained no more than 50.
Change charging location to a cooler location. Charging iPhone while its off. Charging iPhone to 100. If youre charging your iPhone in a particularly warm location the iPhone will automatically stop the battery from charging past 80.
