My iPhone 7 has been super slow on iOS 14, all versions. Sometimes freezes when I lock it and takes seconds to wake back up.

I've also had some weird bugs for a long time, both with Messenger and spotify, that haven't gone away even when I've reinstalled the apps. However, after a restore it was working well. Super fast and no bugs. Then I decided to restore data from my backup and the bugs were back.

I'm not sure if the bugs are in iCloud or in my backup data, as I hadn't signed in to icloud. Any ideas? Just clear the phone of data and try again maybe? Is there any way to selectively import backup data e.g pictures but leave e.g spotify data? Or is some stuff stored in the cloud?
 
Anyone? Is it a fault with my backup data or with iCloud somehow?
 
Had iOS 13, upgraded to 14.0 Slow. 14.1? Better, then slow again. 14.2? Much worse and also still slow.

Restored phone, used backup. Still slow, Spotify buggy.

Restored phone again, no backup. Fast but became slow. Solved bugs.

iOS 14 grinded my iPhone 7 to a halt. Bought a 12 mini instead. Problem solved, albeit expensively.
 
I usually see the same behavior with devices that have some kind of battery issues going on. Did you check your iPhone 7's battery health and whether "Peak Performance Capability" was still supported?
 
Battery was bad actually as in that it had lost a lot of capacity in a short period of time (had it replaced at "teknikmagasinet" in Sweden, they installed some cheap crap that degraded to 72% capacity after a few months). The phone reported it as supporting "peak performance capability" = no toggle to disable throttling, but it also reported the battery as in need of service.
 
In my experience, when battery health drops below 80% iPhones act up in one way or another. Yours might have been the same - even if the Peak Performance Capability was (surprisingly) reporting otherwise.

On another note, iOS 14 seem to have (had) some battery drain issue on some versions. Since you said this issue began when you upgraded to this version of iOS, I imagine problems were already brewing under the surface of things, and that they came to light with iOS 14 because the battery drain glitch escalated the matter further.

I have a 7 at my end too. The battery health is currently at 89%, and the performance is rock solid. (Touch wood!)
This further makes me think your issue was not related to iOS 14.
 
That makes sense. Though to complicate things, when I check the battery capacity via my computer (coconutbattery), it reads the iPhone 7 as being at 92% and in good condition. Fair enough if it can't detect the "need service" as displayed on my iPhone, but that the capacity is reported so differently is weird to me. The restore unfortunately didn't help either.

But yeah, I'm happy with your explanation and I don't use the 7 anymore. But can't help to be a little bit curious though. Maybe the presumed crap quality battery is partly to blame here.
 
If you do not plan on using that iPhone 7 anymore, I recommend checking Apple's Recycling Program (AKA Trade-in Program). It will be good for environment, it will free up space in the house, and you won't have to worry the hazards involved with malfunctioning batteries. You *may* get an iTunes Gift Card too.

Pays about $80. I'd rather just have it sitting as a spare in case the 12 mini acts up. My 5 had to be repaired three times, didn't have a backup back then. Maybe recycle it when it's completely past all usability.
