I uses 90Hz and save battery with WQHD+
Battery drain is linear can last me 8hrs. With normal surfing, social media, taking photo 10+ shots, Whatsapp messaging etc
My Android system drains at 8% only.
The charger u show is only 55w..... The new one is 80w comes with 120w power supply.
U try using 67w supply direct to the phone. It should be full speed.
Yeah agree with you. But at this junction only can see if there's updates to solve the thermal issues. I also found that setting manually at 90Hz is good too :)
