did you try resetting your handset? If you get updates where the version of the OS changes, example from Android 9 (Pie) to Android 10, then in this case it is a good thing to do a factory reset. This will clear up many unnecessary caches and files in your phone and will really boost up performance.
Kindly follow the below mentioned step to improve the performance of the device
Check Auto Restart should be Off: Setting> General management >Reset>Auto restart off.
