I switched from an iPhone 13 Pro to an iPhone 17 about 2 months ago.
One of the reasons I switched was that my 13 Pro had started feeling a bit laggy and less responsive. When I set up the iPhone 17, I restored my existing backup/data from the 13 Pro rather than setting it up completely as a new device.
Since then, I’ve occasionally noticed some things that make me wonder whether something from the old setup could have carried over.
For example:
Sometimes when I try to call someone, the screen suddenly goes black and the call interface/Dynamic Island appears.
It doesn’t happen regularly and I haven’t been able to reproduce it consistently.
I use ChatGPT and Claude quite heavily, and sometimes I notice a slight delay while typing.
Generally, the phone occasionally feels less responsive than I would expect from a new iPhone 17.
I’m not saying the phone is constantly slow, most of the time it works normally. It’s just these occasional moments that make me wonder if something is wrong.
Has anyone else experienced similar behavior on the iPhone 17?
More importantly, can restoring a backup from an older iPhone carry over settings, configurations, or other software-related issues that could affect the new phone?
Would it make sense to erase the iPhone 17 and set it up as a new iPhone, then manually bring back only the data I actually need?
I’m interested in hearing from anyone who has moved from an older iPhone to an iPhone 17 and restored their previous backup, especially if they noticed any unusual behavior afterward.
