Hi drjaimewong,
Could you tell me your current firmware version?
* Find the firmware version in Settings > System > About phone > Software information
Does battery drain more when using any specific apps?
For battery drain in standby mode,
in order for us to verify, please kindly follow the steps below and show us the screenshots.
1) Charge the phone to 100% before going to bed > remove the charger and turn off screen> the next morning before using the phone, please provide me two screenshots:
a) Settings > Battery
b) Settings > Battery > ""Advanced battery usage"" (click on the battery icon to access)
2) Provide me the time interval and the battery level: for example 23:00 (100%) > 08:00 (90%)
3) In the meantime, were mobile network, WiFi, and Bluetooth turned on or off?
Thank you 🙂
