They weren't just slowing down old phone's. They were maintaining battery life by throttling the CPU. As far as I know they added a setting to turn that feature off. Not sure if that's on by default or not.

It was off by default, but it turns on if your phone unexpectedly shuts down. They later added the option to turn it off. 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.

There are a few factors at play such as temperature that can’t be exactly characterised so it has to be conservative.

    Apple said it themselves about the 6S at least: https://www.theverge.com/2016/12/6/13853280/apple-iphone-6s-battery-problems-fix-explanation https://www.theverge.com/2016/12/6/13853280/apple-iphone-6s-... 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.

      I don’t see any indication this feature was put there to cover up the issue. It would definitely help since it helps with battery degradation in general, but they would limit it to specific models if it was that targeted and there would be no need to still have the feature around today.

        "For iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation), iPhone 7, and iPhone 7 Plus, iOS dynamically manages performance peaks to prevent the device from unexpectedly shutting down, so you can still use your iPhone." 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.

        The feature still exists today. On my iPhone 11 I can go in to the settings under Battery -> Battery Health & Charging and see that I have “Peak Performance Capability”. 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.

        It's called something similar, but it doesn't seem like the same thing. For one, I don't think you can force an iPhone 11 into max performance mode like you can with a 6. If you read the context around that quote on Apple's site, the later phones are called out separately. 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.

Avoiding having the phone shutdown by drawing power faster than an older battery can support, actually. You can’t turn that off, but there’s now more communication that replacing the battery will make the phone faster.
