I just “setup as new” a few days ago. I had a couple of bugs that had been so long standing I was convinced it had to be something wrong with my setup only and it was carrying over when I was restoring from backups. These bugs had followed me through multiple iPhone versions and multiple major iOS versions.

After doing the full reset and “setup as new”…those bugs still exist and it was a wasted effort.

Restoring from backup is fine.

I factory reset once when I had a 5C and that was only because the memory function was so messed up that I could no longer receive text messages.

Occasionally very rarely something doesn’t work as expected usually an app but sometimes even my ringers and/or notifications act strange so I will do a soft reset. (Just turning it off and back on)

Reset? Like wipe all your data? No, never do that unless it’s actually necessary for some specific reason.

I’ve never had too. I’ve went from the 7+, 10s, 13 without a factory reset. The person who told you that must have came from Android originally.

No

iPhone „science“ reminds me of snake oil „science“

Uh, no? There are those rare occasion when Wifi stops working properly so a shutdown/reboot is necessary. That is not a reset.

Your friend is mistaken.

I would say a BIG “N-O” on that notion……

Just do it when there is a major iOS update. Otherwise, there is no need to.

Most ridiculous thing I ever heard.

… at first, I thought you meant “restart”. I do restart every now and then but only if something is acting weird or buggy. I can go months without it but sometimes I will.

It’s generally not a bad idea to to restart smartphones but iPhones less so than other OS’s.

Only if I’m having an issue that restarting doesn’t fix. Doesn’t happen often as the process is easy but will take like 30 minutes between erasing and redownloading everything.

Don’t reset unless you have an issue that would seem to require it.

Reset means rebooting the phone? I only do that when I update OS or I encounter an issue that forced me to reboot.
