Why Is My Phone Not Charging As Fast. If you have any other questions feel free to ask them in the comments section below. Go to Menu Settings Battery and look for the Fast cable charging option.

If it doesnt try restarting the phone. Then check if the charger cable and your phones charging port are faulty. When Optimized Battery Charging is active a notification on the Lock screen says when your iPhone will be fully charged.
If the charge of your smartphone is depleting too quickly then that is a clear sign of a damaged battery.
Answer 1 of 5. I have a fast charging block and fast charging. My phone is plugged into the USB in the computer charging. Its always going to be slower than the wall.
