Laptops cannot survive 4 days on a single charge, in contrast to phones. It's the exact opposite of what you're saying. Also, calling me uninformed so quickly shows something I guess...

Phones can’t last 4 days on a charge! You’d be lucky to get 6 hours of solid use out of a phone whereas you’ll get a good 10 hours from a laptop, and you use a phone more than a laptop so as I stated, the charging cycles will be higher on a phone.

As a case in point, my laptop purchased on 3 October 2017 currently has 21 cycle counts and my phone purchased on 3 November 2017 currently has 30 cycle counts.

In fact this is the precise opposite of a conspiracy theory. Conspiracy is Apple deliberately slows old phones down to make people upgrade. Reality is, Apple slows down the processors of phones with worn out batteries to make them last longer.
First half of both those statements are true, second half are both opinions.

You're advertising a device with a certain battery life. At no point should you be deliberately be lowering that battery life after a sale to make up for a different deficiency

That's the point though. No one's
deliberately lowering the battery
capacity after you've bought it, that's just an intrinsic part of the way batteries work. CPUs don't get slower unless someone decides to make them go slower.

get off your fucking high horse. batteries degrade, there is no way to maintain both battery life and speed. They made the decision they felt would be the most benefit to most customers. Better to have a slow device than a dead device no?

That's bollocks. Old batteries don't make CPUs run slower unless you underspecced the battery to start with.

CPUs will only get slower when the battery has deteriorated to the point where it can no longer reliably power said CPUs. By gum, I think you are finally getting it!

You can't under spec a battery in terms of being able to prevent it from deteriorating. All batteries deteriorate. You cannot spec a non-deteriorating battery no matter how much you wish, hope and pray that you can (or you expect Apple to be able to for some reason).

Or you could just make a removable battery, but that's crazy talk. Same reason I buy cars with the sparkplugs welded in, and the batteries sealed in the lower frame rails. Saves space, and keeps the center of gravity lower.

Removable batteries still deterioatate.

They absolutely do, but for ~$10 you can get fresh out the box performance, and a complete idiot can install it.

Great, but I’m not really sure what your point is given it’s very easy to get a replacement battery from Apple too.

For how much? How much does it cost to install? What percentage is that of a new phone? If you don't get my point, you truly are a dim bulb.

It’s only £80! If that’s too much for you then we are playing two very different games here.

but battery life degradation is right?

and Apple decided it was better to degrade performance to prevent battery life degradation

i call that an intelligent design decision

That's bollocks. Old batteries don't make CPUs run slower unless you underspecced the battery to start with.

but they do make battery life shorter

do you not understand that?

apple found a way to counter that battery life degradation. yes there are tradeoffs, but all engineering is about tradeoffs

apple made the tradeoff they felt served the most consumers the best

you may disagree with their tradeoff analysis, but they put a ton more research and thought into it than you did

Yes, but normally the CPU runs at a normal speed or the OS notifies you that it's gone into power saving mode.
You can't under spec a battery in terms of being able to prevent it from deteriorating. All batteries deteriorate. You cannot spec a non-deteriorating battery no matter how much you wish, hope and pray that you can (or you expect Apple to be able to for some reason).
Well you can expect them to spec either the CPU speed or battery capacity to be able to run the CPU at advertised speeds!

Eh? The batteries in the iPhone degrade the same as other batteries, just that other phones dont get slower as well as getting less battery life.

you're just trolling right? haha, so funny. not. iPhones don't lose battery life (at least as much as they would otherwise) precisely because of this tradeoff

As far as the engineering goes it's a good compromise. The only real error I see, is that Apple could have been more forthcoming about it. "If it seems your phone is running slower, it may be. Time to have your battery checked." Or something along those lines.

Yeah, I guess a persistent notification telling you gone into limp mode would be a bit fairer.

Eh, some people just hate everything Apple does. And it shows up in every thread Apple is mentioned. I'm sure if they cured cancer, and gave it away with a free unicorn they'd come up with a reason to hate on it.

After discussing the insanity of a removable battery, we could also talk about other crazy shit, like letting the user decide what to do. Give a selectable option to degrade performance, and let the user choose, but that would literally be anarchy.

for what? that slowing the CPU prolongs battery life?
You were disagreeing with "just that other phones dont get slower as well as getting less battery life.". So do apple batteries get slower and lose battery life as well as opposed to just losing battery life?

AFAIK this was to stop them shutting down suddenly rather than to stop the battery life getting progressivly worse over time.

I'd not be entirely happy with just a notification if I couldn't disable limp mode tbh. It would still be better than doing it and not saying anything to anyone.

slowing down processors make them more efficient. this is a well known and understood fact. even the author of the article understands it

That absolutely makes the phone more useable — it apparently helps stop random shutdowns, which are a major pain. And I would think it helps with battery life in general as well.

yeah, NSS

however even if you were 100% correct and it was 'just' to stop random shutdowns, it would be a worthy goal to accomplish and I see nothing wrong with Apple doing it
