Got a wireless charger (PowerPort Wireless A2511) a couple weeks ago for iPhone 8, it charges the phone well but even after the phone reads 100% charged the blue light on the charger stays lit and doesn’t alternate with the red light like the instructions say it’s supposed to.
It also gets a little warm but not alarmingly so.
Is this normal? Is it overcharging my phone or hurting the battery in some way?
