Hi mohamedyusuflbk,
Please tell me your firmware version.
Please check if there is battery drain issues in sleep mode,
in order for us to verify, please kindly follow the methods as below:
(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 (95%)
(3.) In the meantime, were mobile network, WiFi, and Bluetooth turned on or off?
Thank you 🙂
