Other IPhone Battery Replacement Process At Apple Store?

For a once-off, why not just backup to your local PC.

Yes for a one-off backup, I'd just use a computer. You just need a normal, regular USB-C cable (essentially like the charging cable you use, just instead of plugging it into the power brick, you plug it into a USB port in your computer).

If you only have a PC, not a Mac, I believe you use iTunes software to create a backup. Should be fairly straightforward.

Back up your iPhone, iPad, or iPod touch in iTunes on PC

In iTunes on PC, back up your device to your computer. You can then restore your device if you have any problems.

Y’all OP’s out of the party. But thanks for sharing your helpful tips, yes indeed we do have to do any type of backup in order to ensure that the personal data is properly maintained and preserved should the iPhone be wiped during repair.

To sum up:
Either use Finder on Mac or iTunes on windows to backup y’all’s iPhones into your computer.
You can also use the temporary iCloud storage option in Reset or Erase iPhone section to backup your iPhone by allocating temporary spare storage. Though it’s intended to help users avoid paying for iCloud storage upgrades on restoring from backups it is useful when your iPhone needs to be restored for any reason.

Just make sure to do a complete backup the night before you head to Apple Store!
