Just done my 2nd discharge and charging. Below is what I found.
Device Setting:[Remain the same]
Major Changed:- No gaming activity (previously 1 h 28 m gaming)
- Use ShopBack for 25 mins
Result:- 25 h 54 m usage from 100% to 1%
- 7 h 44 m SOT
- ShopBack apps alone consume 15% battery with just 25 mins usage according to AccuBattery Pro (sharp drop around Time Bar 5 to 6 in screenshot below)
- Overnight standby drain of 5% over 7 hrs Screen Off Time (from 18% to 13%)
- Charging time from 1% to 100% with standard charging: (GSamBMP seems more accurate on actual full charge)
3 h 25 m according to GSam Battery Monitor Pro (99% to 100% take almost 41 mins)
3 h 8 m according to AccuBattery Pro
Conclusion:- Can concluded that without gaming alone can improved your SOT by around 100% comparing to gaming SOT usage.
- ShopBack apps is very power hungry and with itself alone can only get you estimated 2.5 - 3.0 hrs SOT from 100% full charge.
- Assuming that without ShopBack apps running and no gaming while keeping the rest of device setting the same, you can probably get estimated 9 hrs SOT or more.
- By enable "Keep Open" on AccuBattery Pro from Recent Apps, it is able to avoid getting killed by system and able to record single full charge session of 1% to 100% instead of being "chopped".
- AccuBattery Pro is also able to detect a full charge and give an estimated capacity of 4,903 mAh. (official rated battery capacity was 4,855 mAh)
- Suspected there is an issue with my charger due to longer than expected charging time. Will re-test this again.

good analysis on your end. during the standby, are you able to determine what is/are using the most battery out of the 5% drain?
