I don't know what is happening to my battery

[BYN0110]

My s 23 ultra isn't even like this in first 2 months. I have notice that my battery drain quicker than before. I always check the background running apps, and there's always no apps in there. I don't know what making my phone battery drain this fast. I have tried the diagnostic and it says normal. I am mostly getting now 4 hrs screen on timewuth light use. My battery drained for 10% with 5 hrs screen off time. When I noticed the drop, I check the background and there was no apps was running. I even check the battery section, at that 5 hours screen off, i doesn't show any apps was running at that hours. I really realise now that I should stop hoping for my phone battery to get normal now like before. Idc about the opinion of yours going for light performance/ battery saving feature or ect.. I just want my old battery performance back with just defult settings on my phone.

Try to see if this is turned on or off and maybe give it a try. Settings >>> battery and device care >>> open battery option >>> scroll down to more battery settings >>> make sure adaptive battery is turned on and the profile below that is set to standard. This will monitor and learn the apps you use and put apps you don't use much to sleep to save battery. Also turn your screen brightness to adaptive and screen off timer down help save battery.

Have you traveled to "government restricted" countries recently? They could "tag" your phone.
