I first deleted all the downloaded applications and also deleted the Android folder, and then I restarted the phone once, and then I started downloading the Android operating system, and after installing it, I did a factory reset once, and now there is a problem.  I do not have it with Android 11. But why after the update, a new version with a volume of 325 MB came again and I had to download a new version again
I do not have any problems with the new Android update now, and the problems with Android 10 have been fixed, only a certain amount of battery charge will be emptied earlier in working mode, but not in standby mode
