Why does everything get worse whenever you update?

[swealpha]

Hello!
I have a Macbook AIR 2024 m3 16gb 500GB. Allways when I update MacOS it is getting hotter, slower or even lower the battery life. 90% battery life right now.

Why is it like this?

Right now my standby cpu temp is about 70c. I remember before when it was like 40c.

It is like this with Iphones also, whenever you update it gets slower or the battery dies faster.

I guess Apple just want us to buy a new device more often. Why doesnt EU or US complain more?

Why am I even asking when Apple have admited this before.

Apple fined for slowing down old iPhones

Apple agrees to pay a £21m fine in France for not making it clear that it slowed down old iPhones.

From now on, I will never ever update a OS if I am not forced to. 😠​

Installing a new OS is a lot of work. There is unpacking and processing the data, several GB of data to write. First launch will have lots of setting up to do, filling caches, rebuilding databases for Spotlight, LaunchServices, Mail, etc, etc.

However, this should all die down, and battery life/temperature should be consistent with previous usage.

It makes no sense for Apple to make the OS use more resources -- because that would be the case for new Macs, too. Apple is all about showing how efficient their laptops are. (In fact, your MBA is the current model, so why would Apple make the model they are selling now to run worse than previously?)

It's also true that "a problem I am having with my Mac" could just be a particular combination of circumstances on this machine, rather than something that affects everyone equally.

What OS did you update to, and from what?

Another possibility is that if you have very old software that isn't compatible with the new OS, it is using much more CPU than it ought to be. So check Activity Monitor and see what is using CPU.

Generally, keeping reasonably up-to-date is a better strategy for avoiding problems than keeping apps and the OS years behind. (By "reasonably", I mean you don't have to be right on it the second it drops...!)

It doesn't, but some people can experience issues. The vast majority will not have any issues at all. I am on an M1 Max and no issues after any updates.

'Admitted' is doing a lot of the work in your sentence. It makes it sound like Apple admitted they've slowed down devices to encourage customers to "buy a new device more often" as you say, when what they have actually admitted to is taking steps to prevent iPhone from ceasing to work at all.

So essentially Apple have preserved customer's ability to use their devices for longer. The trade-off is slower performance, but given that battery capacities diminish over time and have a finite lifespan – what else is the solution (unless you want it to just randomly shut down)?

From the BBC News article:

In 2017, the company confirmed it did slow down some models as they aged, but not to encourage people to upgrade.

It said the lithium-ion batteries in the devices became less capable of supplying peak current demands, as they aged over time.

That could result in an iPhone unexpectedly shutting down to protect its electronic components.

So, it released a software update for the iPhone 6, iPhone 6s and iPhone SE which "smoothed out" battery performance.

The practice was confirmed after a customer shared performance tests on Reddit, suggesting their iPhone 6S had slowed down considerably as it had aged, but had suddenly speeded up again after the battery had been replaced.

Allow users to downgrade to the older OS? Allow users to silent the constant update nagging while they're at it. Separate the OS from the features update. Let those running older OS to run the latest iMessage and Mail. Unless the new features requires functions of the newest OS to work, I see no reason why features should be bundled with the OS.

I'm using Android 9 on a 5 year old phone, yet I still get the latest Gmail and Maps. I'm not stuck with the ancient version of Gmail or Maps.
