@LelD Hello, have you tried to Reset the Galaxy S 10 + to factory settings? Save your personal data before proceeding. This procedure will make your phone work more quickly. You may not want to change it.😀 Greetings.
@LelD I agree that the s10 is generally the better device and also has better screen resolution,though some have found the battery life on A53 fairly impressive. obviously replacing the battery an option if the Factory Reset does not improve matters sufficiently. For others pondering comparisons between the two Devices here: https://www.expertreviews.co.uk/mobile-phones/1407169/best-samsung-phone
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
