A lot of reports on the internet about this.
I updated this morning and continued working on an iOS app. Everything felt slow. I thought I did something stupid in my code. Apparently not. As per this Geekbench 5 test, the phone scores ~1200 where it used to regularly score ~3000+ (!!!).
There's a lot of rumors what's the cause of this but no official explanation from Apple as of right now that I can find.
- raspasov 5y agoAaaand it's fixed... I didn't do anything specific. It took a few hours (?!) after the upgrade. It scored many times low, but now it seems to score at a normal level (3000+). Really wonder what the explanation for all of that is.
- toomuchtodo 5y agoBackground process doing some sort of migration or other data conversion between versions? Strange the device wouldn't wait until during the night while plugged in, but without context, that might not be an option.
- bigphishy 5y agoKind of sad that we don't have a top or process viewer. Or free -m / open system. This makes me yearn for an open source OS on my phone again, I may have to look into a pine phone.

- raspasov 5y agoYes... I remember back in the day I had terminal with root access on a jailbroken iPhone. You could install almost any package on your phone via terminal.
- lifty 5y agoI agree, but it shouldn't be a classic process viewer. It should be a task viewer which has some context or understandable description. Like "photo analysis job" or "iOS 14.5.1 data migration job".

- saagarjha 5y agoIf you connect your iPhone to your Mac you can run Instruments on it to figure out what is going on. I used to recently to figure out that Slack had been making my entire phone slow because it was busy looping in the background.
- tgv 5y agoMight explain why my battery dropped that much, too.
- mxcrossb 5y agoStick a fan in it so I can hear if a background process is being run!

- DeliriumTrigger 5y agoIndexing or rebuilding I guess.
- yardstick 5y agoYeah pretty sure it’s this. Have seen various complaints about both macOS and iOS sluggish performance post upgrade to end up being just temporary while caches / indexes rebuilt, file systems migrated etc
- raspasov 5y agoLikely, yes. The thing is, the phone does not "heat up". Perhaps they throttle the whole phone down globally and let the background update processes run at a slow speed/low priority so they don't heat up the phone too much.
- kwdc 5y agoYet no notification. The goblins inside the ios doing their thing behind closed doors. Even a heads-up saying "hey we're doing some work behind the scenes on your device as part of the upgrade" would do.
- raspasov 5y agoThat's potentially a good idea. It could even be hidden in the developer section, since those are the people most likely to notice.
- dylan604 5y agoIs there mention of this in any of the dialogs that one is asked to click "I have read and understand" that were not actually read? I remember Photos telling me that it was scanning the library to do their new layout after whatever update that was. That was to that specific app, and not a system wide notification, but it also said it would be paused until it was plugged in. I could see a new something in the Settings that indicates post-OS upgrade showing migration status being useful.
- pawsforapplase 5y agoOne of iOS' more annoying quirks is its opacity and lack of user affordances. The volume buttons don't seem to affect haptic noises, but the mute button does. The OS locks up for about a minute when you change passcodes while it re-crypts everything, but from the user's perspective it just looks frozen. The implications of opting into their 'find my...' and iCloud networks are not adequately explained. The devices take 15-30 seconds to actually cut power after they appear to shut down, and during that time they won't respond to any button presses. The list goes on, using a modern iPhone feels like you are constantly negotiating with a disingenuous UI. The OS regularly claims to be done with something while it continues working furiously in the background, and it is full of undocumented exceptions to common settings.
- xallarap 5y agoTo slow you down so you can't sudoku faster than the queen bitx. Or maybe to allocate resources to background daemons that attack wielders of non-iphones.
- raldi 5y agoEvery time there’s an iOS update, the internet goes crazy about their phone being slow or hot or not holding a charge. Then, a day or two later, the background system processes finish doing their post-upgrade homework and everything goes back to normal.
- raspasov 5y agoWell I've been developing iOS apps for a long time, and updated many times. I don't remember anything as dramatic as this!
- raldi 5y agoHmm, if I specifically go looking for reports of benchmarks going down, it does seem to be a much more prevalent story with this version than any previous one.
- raspasov 5y agoYes. The slow down was real and very significant and it lasted hours. It was not people freaking out for no reason.
- raldi 5y agoReports of post-upgrade slowdown are pretty common (google it for various versions), but this is the first time I’m seeing lots of reports of post-upgrade benchmark hits.
- asdff 5y agoExcept for when apple started throttling phones with batteries below 85% capacity.
- zepto 5y ago…to extend the usable life of those batteries.
