Have completely charged phone wirelessly in safe mode. It was showing 2 hours 40 min to full charge but actually took 4 hours to complete. So either issue with samsung phone or samsung wireless pad. But for sure its samsung.
I think no one has a solution to this. Samsung says send phone for repair or else send wireless charger for repair. They know nothing about why phone takes 4 hour 30 min in safe mode to charge phone wirelessly.
After June 2021 update the battery performance is improved but still
Overheating remains when on whatsapp call. within 15 min call temperature reaches from 28 degree Celsius to 39 degree Celsius.
And wireless charging have became even worse now. Within 5 min the temp goes above 35 degree Celsius and then extreme slow charging.
What have you done samsung?
