Aaaand 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.

Background 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.

Stick a fan in it so I can hear if a background process is being run!

Yeah I have 14.5.1 for a few days now and my 11 pro max scored 3509 which is pretty much bang on when it was new. I just went and checked. It’s actually gone up since it was new. I have 3 benchmarks in the 3400 range so if this is an issue it’s either temporary along the lines of someone needing to let background processes finish or some phones are affected but not others.

Every 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.

To be fair, iOS maybe should put some visual indicator that it is doing this. Then everything would be obvious.

"Background system processes running" wouldn't be obvious to non-technical users. It might even be distressing. If the process isn't something that can easily be explained to a regular user, I can see why Apple wouldn't try and communicate about it.

Though I could see maybe detecting that a user is a developer and showing a message only for those users

True, but it could be marketed a bit better: "Update finishing in the background"

"Apple fined for slowing down old iPhones" (Feb 2020 finally brought a judgement around in France) https://www.bbc.com/news/technology-51413724

May 2020 via the Verge. Apple agrees to pay $500 million (715,000 iPhone's worth) in artificial slow down settlement. https://www.theverge.com/2020/3/2/21161271/apple-settlement-...

My FaceID stopped working. I cannot %100 relate it to the update itself, but after the update, I also enabled the unlock with watch, after one day, I decided it it not for me and disabled it. After that my FaceID entirely stopped working. I have removed face id to add it again, but cannot add it back, it keeps saying "move iphone a little lower". Tried everything short of resetting to factory defaults and nothing has worked yet.

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.

If your update system requires 1-2 days of "post-upgrade homeswork" time and slows your phone by 50% in the process, you've designed a very poor update system.

One 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.

The headline is not representative:

> Apple has been fined 25 million euros (£21m, $27m) for deliberately slowing down older iPhone models without making it clear to consumers.
