My phone works normally in every other way, but the battery no longer holds a charge well. I'm considering having the battery replaced and want to know whether the repair process normally wipes the phone or puts my photos, apps, and other data at risk. I already keep my important data backed up, but I'd like to understand what to expect.

A standard battery replacement does not normally require erasing the phone. However, repairs can occasionally go wrong, or technicians may find additional damage such as a swollen or leaking battery. Make a current backup before handing it in, just in case.
There’s always some risk when hardware is being repaired, even if data loss isn’t an expected part of the procedure. Keep both a cloud backup and, if possible, a computer backup so you’re covered before the appointment.
The phone should generally come back with its data intact after a routine battery swap. Still, backing up beforehand is the safest move because data can be lost from unexpected hardware failure or accidental damage, not just from the battery repair itself.

I already have my important files backed up, so I mainly wanted to confirm whether wiping the phone is normally part of a battery replacement.
