I have an iPhone 13 mini running iOS 18, and I've been putting off the newest major update because I'm not a fan of its design and I'm concerned it could hurt performance on an older phone. I need to send the phone in for a battery replacement through my AppleCare One plan, and I'd also like Apple to investigate a possible camera hardware problem: the camera won't reliably maintain autofocus, so I often have to tap the screen repeatedly to get the image sharp.
Support chat told me they probably can't proceed unless I first update to the current iOS release. I'm not convinced the camera issue is software-related since it was already happening on iOS 17, but I also don't want to make a big deal with another support tier if the update is unavoidable anyway. Has anyone had Apple diagnose or repair an iPhone without requiring the latest system software first?

The repair terms allow Apple to install system updates as part of servicing, and the phone may not be able to complete post-repair diagnostics or component pairing until it’s on a compatible current version. Updating before sending it in may be the easiest way to avoid delays.
A worn battery can contribute to performance problems, but replacing it should address that independently of the camera issue. The newest iOS may look different, but current versions generally remain usable on an iPhone 13 mini, and Apple’s service process will probably require the update regardless.
It’s still worth listing the autofocus problem separately in the repair notes. The fact that it happened on iOS 17 and iOS 18 doesn’t prove a hardware fault, since a later release might contain a fix, but Apple can test the camera once the phone is on the required software.
Apple usually expects the phone to be fully updated before running diagnostics or starting a repair. The repair tools, logging software, and post-repair checks are tied to current system versions, so support may not be able to complete the process on an older release. If you send it in, they’ll very likely update it during the repair anyway.

That makes sense, although I’ll make sure everything is backed up first in case the update or repair requires an erase and restore.
