So on your own volition you decided that you wanted to upgrade your phone?
I didn't want to upgrade - there were no new hardware features that my wife wanted on her phone. We tried doing a fresh install and the performance still sucked. We thought maybe it was thinking the phone used to work a lot better. We didn't think there was anything else we could do after we did a fresh install. We knew the battery was old, but we didn't care about it since we always have access to plug in. So if you think that is us _wanting_ to get a new phone, then I don't even know what to say. They degraded the phone to the point that it wasn't usable.

Consider this though: You are not allowed to downgrade the OS once you’ve gone up. Apple can cite security concerns all they want, but the fact is they could keep older OSs in their final version optimised for several years if they chose to. Their strategy is blatantly part of planned obsolescence.
 
So I'm curious, why didn't random shutdowns happen widespread for iPhone 5s and below?
I don't think Apple designed their phones to exceed power envelopes back then. The CPU didn't draw that much power all at once. The newer chips are able to draw power that exceeds the power supply in bursts that actually shut the system down.

That is still 55% more than if it switched off. I know what I would prefer ;)
Not if you had the phone plugged in and needed to run an app that used a lot of CPU. The problem continues even when plugged in. So basically you can't run apps that could run before Apple flipped the switch on your phone to make it run degraded/unusuable mode.
 
The first time you try to run an app that needs a lot of CPU and was able to run fine in the past, then you will realize how this is a bad thing.

Basically they've just split the install base. iPhone in normal state and iPhone in degraded/unusable state. This makes an enormous difference in any apps that are CPU dependent.

I do understand what you are saying.

BUT.. Without this patch, the iPhone would have spontaneously rebooted or shut down. I would argue that a slow phone is better than dead phone.

HOWEVER, I what I would really rather see is a warning message like this when I try to open such apps: "This iPhone's battery has been degraded and you may experience decreased performance."

If that is what you use your phone for; high cpu charger connected applications than yes for that particular use case agreed.

Can’t help but think that anyone making calls, sending text messages, reading emails, browsing a website or posting on Facebook will notice any difference at all.
 
Now I feel much better leasing my iphone each year from T-Mobile. A new iphone every year, i won’t have to experience any of this shenanigans.
 
im guessing they had less power requirements than the newer cpus and the battery designed for them was adequate
So this could possibly all be solved if Apple gave the iPhones bigger batteries. Not an engineer so I don't know if that's how it works.

I think this has been happening to the plus models too right? So bigger batteries wouldn't solve it?

yes, bigger battery ( not necessarily bigger in size, just larger capacity) = more stored energy

my air 2 is 3 years old, no issues. runs at same CPU speed as it did the day I bought it. Original battery.
 
CPUs don't degrade over time the way car powertrains do. But if you lost half your car power in the first year, you'd certainly have a valid complaint.

And at least you'd know why your car lost power. :p Even Apple is telling people their batteries are "healthy" and fine, not in need of replacement, yet they're being heavily throttled.

How is Apple telling people their battery is healthy while also throttling? They make no indication of battery health.

Here's my perspective on this: why did my phone run for 2-3 days on my usual load (games, browser, messages, etc.) on 10.x (and earlier), but now with 11.2.1, I get much less than a day of use with the same app mix? The only thing that changed was the OS! :^(
 
No matter how much you slice and dice this, the reason Apple did not disclose this, or add a toggle switch with a full explanation (even if its implemented automatically) is to encourage users to buy a new iPhone.

The technical reasons are believable but the method reveals the motive and hence proves Apple is dishonest.

Hence my original comment. I upgrade when I’m ready because a new phone offers something of value. Can’t really say I’ve had a phone slow down to the point it annoys me. I have two 5s from 2013 and they are running like a top in 11.2.5. So I don’t believe there is a grand scheme.
