Except for when apple started throttling phones with batteries below 85% capacity.

…to extend the usable life of those batteries.

Yes. So now instead of driving 100 miles with 100 miles pers hour I'm now doing 100 miles with 85 mph.

Did you know that batteries are made of chemicals and don’t last forever? Over time their performance degrades, but you can use them for longer if you don’t use as much peak power.

In case anyone missed it, the author of the submission added an update [1] saying that after some time the issue went away: > 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.

After the update I definitely had at least one day of terrible idle battery life.

It's not uncommon with updates though, nothing alarming.

Yet 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.

Is 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…

If there was I didn't see it. But that is no surprise. Its not a way for them to escape a notification either imo. Especially if its slowing everything down.

This is how Android shows it, and I think it is quite good because the phone feels slower while finishing the upgrade.

But unlike this (which is timed in hours) in Android it's done in a minute and then the notification is gone. Maybe Apple should start by doing the update in minutes first.

I find it really bizarre that it takes hours to run whatever background process iOS has after an upgrade, especially because in Android's case this is AFAIK rebuilding the Dalvik bytecode while iOS should use a compiled language (ObjectiveC/Swift).

Does someone knows what is iOS doing at 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-...

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 .

That really says it all. However, I am also shocked at the lack of consumer protections regarding such artificially imposed slowdowns.

Something similar happened with the macbooks a few months ago. Apple changed something in one of their services which made it impossible to open non-Apple applications and made the entire computer grind to an halt. After thirty minutes everything just started to work again for no apparent reason. Turns out that their service for validating application certificates went down for some time. Not sure if it’s related at…

Using macOS on very shoddy internet is almost impossible. You're better of disabling wifi. I can't believe I'm typing this.

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.

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.

To 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.

It wasn’t artificial, it was required to prevent random shutdowns due to over-voltage on a degraded battery. The fine was due to them not telling the consumer like they do now in ‘battery health’.

I never experienced a random shutdown on my old iPhone despite not allowing the software update for years. Finally, when I did update the phone, everything was noticeably slower, instantly, so that sounds more like good PR management than actual consumer-minded thinking to me. Yes, devices get old and batteries get old, but my understanding is that this happens even if you replace the battery with a new one, which would negate this argument.
