I have been using galaxy s10 for almost a year now. Since the last few updates I have noticed heavy battery drain issue even when the phone is in stand by mode with ever turned off except mobile data.
Hi, please go to Settings > Device care > Battery > Battery usage, and check which apps drains your battery most, click the apps and turn 'Put app to sleep' toggle on, let me know if this was helpful.
Battery percentage may vary according to the usage (internet, call, video playback, etc..). However, if you feel that the device battery drains quickly when no function is used, please send the device to one of the service centres to discover and fix the problem. www.samsung.com/ae/support/servicelocation/.
