JayeshRangwani , via OnePlus 9 , Jul 28, 2021 : Yesterday it's self purchased one plus 9 and battery is draining quickly 10% down during night (mobile data and wifi switched off) 25% down during heavy usage for 20 mins (Data trf) 15 % down in last 25 mins (low usage) Software-up to date Any suggestion?
McJader , Jul 28, 2021 : Just saw this is a new device. It will take time to get adjusted to your use cycle. Charge it for 3-4 times. It will get better over time. The first day is often the worst.
JayeshRangwani , via OnePlus 9 , Jul 28, 2021 : Update : Working better after draining battery to zero and charging again at 100
