Battery life depends on the usage and various other factors,Check the battery life in the device care--->phone diagnosticsIf it displays as weak battery then you probably might have completed 1200 cyclesIf it's bad then time to replace

Check in the Samsung cloud, if any backup available for logs but max 2500 entries will be available

Might be inventory issue in your area, bcz I got my display replaced last month in Delhi NCR
