It has nothing to do with overheating. It is battery ageing. The internal resistance of a battery increases as it ages, leading to brownouts when peak current happens.

The throttling feature still exists in iOS. All that’s changed is that you will be made aware that it’s happening and you can switch it off if you prefer a brownout when your battery is degraded.

Other manufacturers are happy to let your handset reboot, it could lead to another sale for them. Some would call that planned obsolescence.

yawn Why my 8 years old Moto XT910 eat the battery like cookies but did not reboot? It's battery wasnot only old, but swollen a bit, it's USB port was damaged so sometimes the charge didn't actually happened... but it still could survive a couple of hours with enabled radio and GPS, serving a navigation app with 3G updates? And didn't reboot?

I’m not sure what answer you’re looking for here - each system is different. Design, manufacturing, usage patterns will all play a part.

When batterygate happened my wife’s phone was throttled but mine wasn’t. She didn’t care and never got the battery replaced but she definitely would have upgraded sooner if it was rebooting.

Are you saying that Apple use different battery technology to everyone else? Or what is your point?

Probably because it's a simple, slow dual core Cortex A9 with low enough power draw that it doesn't stress the battery enough to matter.

I had one of the early generation 17" MacBook pros that ended up with a swollen battery. And when I say swollen, I mean the case eventually split in two and was about 1/2" taller than it was originally.

Granted this happened because glue in the battery was compromised by excess heat because Steve Jobs preferred heat over the sound of a fan, but the machine never rebooted or shut down due to heat or decreased max voltage.

It was a rhetorical question, yet a Jobs' fanboi couldn't resist, see the neighbouring comment.

> each system is different

Except in that part it's pretty much the same. Or your battery, even discharged, can keep up with a full load from a CPU, GPU, WiFi and GPS modules eating amps, or it couldn't even when it's fresh.

If at 3V your battery couldn't power the system then you shouldn't show 3V as 30%, you should show it as 0% and adjust %/V curve accordingly.

It's simple, it's about momentary load in amps, but "only some iPhone 6S models manufactured in September and October 2015 had suffered from a battery manufacturing defect" yet millions of iPhones were slowed down ~~totally not beacuse Apple needed to sell the next iPhone~~.

And as an anecdote - even after the years of abuse, the last time I used my XT910 it was literally showing 10% when I enabled the radio so I could receive a SMS from my bank on it. I really expected it to just shutdown (because enabling radio means data too, so all that bullshit rushed to update their things and using data => more power draw) and for me to be stranded in a remote city without money. But not only it did survive that, it kept chugging for another 4 hours, with radio disabled, ofc. *shrug_emoji*

> Or what is your point?

What people would eagerly drink any Koolaid what would make them feel entitled or standing out. Which most Apple fanbois vehemently deny.

NB: there are people who just use iPhones/Macs/whatever and don't engage in defending 'their favourite brand', of course they aren't fanbois.

Ah, yes, the mighty Apple chips suck so much what an inferior chips from the other manufacturers never could!

Or you drunk your Koolaid and ignored "GPU, WiFi, GPS" parts.

This is a low quality comment not fitting with the discussions we try to have on HN. Please stop trying to call people fanboys for no reason.

> yet millions of iPhones were slowed

Citation needed. Only handsets with degraded batteries were slowed, and only after the first brownout. Replacing the battery brought it back to full speed. This is the main point people don’t understand. Every phone got the software update. The feature still exists today. But not all phones were slowed. My iPhone 11 will slow if the battery degrades.

If they wanted to sell you a new phone, was that the best way to do it? Couldn’t they… have just done nothing instead? Like the other manufacturers? Instead of prolonging the life of resetting handsets?
