They slowed individual handsets with degraded batteries to prevent resets. They still do. Replacing the battery brought the device back to full speed.
They got flak for not telling the user, so they alert now. All new iPhones have this feature.
Ironically this was actually to extend the life of the device - many people who would have upgraded if their phone was resetting under high load just carried on using it throttled (my wife included).
Apple is the only malicious perpetrator here. For many years they had specifically denied that they were doing this. That is malicious and borderline criminal damage.
Then when they got caught they came up with plausible deniability. It was evil, it was dishonest and it was awful.
Replacing the battery brought the handset to full speed. How do you fake this well enough for it to be only “plausible deniability”?
The Apple PR people are reaching pretty low trying to deny this ever happened.
> Then when they got caught they came up with plausible deniability.
This is the bit you need to prove. You are implying that they were maliciously doing something underhand rather than implementing a feature to stop degraded batteries causing reboots. How do you implement the exact features required for degraded battery management when you are trying to do something else like slow phones to sell more? That’s the bit you need to explain.
As far as I know they added a setting to turn that feature off. Not sure if that's on by default or not.
The thing is, they were covering up a battery defect unique to a few models like the iPhone 6. Also the throttling was pretty conservative. It made my phone lag so hard that even typing in a default app like Messages was a chore. My phone almost never shut down even after I disabled it, so it's not like I needed it.
Do you have any proof of this?
> My phone almost never shut down even after I disabled it, so it's not like I needed it.
“Almost never” sounds like you did. There are a few factors at play such as temperature that can’t be exactly characterised so it has to be conservative.
Mine shut down once, at a low %. It was a very easy decision to disable the throttling. Even if I were unlucky enough to get a model that shut down more frequently, the throttling was so bad that it'd have been worth disabling.
It was limited to certain models, which makes sense because personally, I've never seen an older iPhone (≤5) shut off randomly. Apple didn't say what the affected models have in common.
This isn’t an issue unique to iPhones either. Different battery chemistries will behave differently and different technology nodes and designs will have varying supply requirements, but in general the internal resistance will increase as the battery ages and cause brownouts as the voltage dips under high load.
I understand that batteries in general can have voltage dips as they degrade, but the 6-7 had something especially wrong with them. Unlike Antennagate, Batterygate was a real thing.
11 and above:
> While performance impacts are reduced as much as possible, battery ageing might still eventually lead to noticeable, possibly temporary, effects. Depending on the battery state, level of charge and the tasks that your iPhone is handling, examples might include longer app launch times, lower frame rates, increased processing times, reduced wireless-data throughput, backlight dimming or lower speaker volume. During the most extreme cases, the camera flash or other camera features might be temporarily disabled.

Below 11:
> Additionally, you can see if the performance-management feature, which dynamically manages maximum performance to prevent unexpected shutdowns, is on, and you can choose to turn it off. This feature is enabled only after an unexpected shutdown first occurs on a device with a battery that has diminished ability to deliver maximum instantaneous power. This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation), iPhone 7 and iPhone 7 Plus. Starting with iOS 12.1, iPhone 8, iPhone 8 Plus and iPhone X include this feature; iPhone XS, iPhone XS Max and iPhone XR include this feature starting with iOS 13.1.
You can’t turn that off, but there’s now more communication that replacing the battery will make the phone faster.
The end result for me personally was having a borderline unusable iPhone for how ever long this was, even though it was fairly new. And they never fixed the root cause, which was a seemingly flawed battery design.
