one thing you can do is after full charge, note your time as after 12 o'clock it will change so e.g. you full charge today at 9 0 clock, and that time you sot shows 4 hrs. just note down this 4 hrs. and after you reach 0% check sot, if it shows 14 hrs. then simple deduct that 4 hrs. from it 14-4=10 hrs would be your sot from 100 to 0.
yes @Blackwinter 😊😊 its true, one person posted earlier that too much battery drain this and that... i asked his sot he replied 12 hrs i said its ok then he replied no its not ok it has 6k battery it should last for 2 days at least.
