Watch does not hold charge and is only 3-4 years old and my husband has a series 3 and it is fine.
Apple Watch 6 SE does not hold charge and is only 3-4 years old. I have unpaired it and restored from backup. Same . Tried unpairing and setting up as a new watch, same. Within 1 hour it drops to 80% from 100% charge.
