Do Apple really slow down older iPhones with software updates?

If you have an older iPhone that you bought 2+ years ago you might suddenly start to notice a slowdown.

You may start to think Apple are pushing software updates made to deliberately slow down your iPhone to encourage you to upgrade to a new one. But this is false.

Battery degradation

Over time, just like laptop batteries, iPhone batteries degrade, giving less and less battery life and making the phone less reliable. Some power for the CPU comes from the battery, but if the CPU requests for more power than the battery’s got, it can trigger a sudden shutdown.

Just imagine if these kept happening. How unbearable it would be. You may even start carrying around a non-iPhone as well to use in the case your iPhone unexpectedly shuts down.

If your capacity is above 80%, there isn’t really much to worry about, but if it’s under 75%, you might want to start looking at a battery or phone replacement.

Performance Management

Apple’s answer to this comes in the form of performance management. Simply, when your iPhone detects that it is booting back up from an unexpected shutdown, it starts to limit the CPU’s performance to prevent the shutdown happening again. This is why your iPhone will become slower after an unexpected shutdown.

You can turn off performance management either by replacing the battery of your iPhone, or heading to Settings –> Battery –> Battery Health, where an option to disable it should be present provided your iPhone is running iOS 11.3 or later. You can also see your battery health percentage here. Please be aware that if an unexpected shutdown occurs again it will be enabled again.

iPhone 3G, 4, and 4S slowdowns

Despite what me saying above was true for most iPhones, it appears that the last major OS upgrades for these devices slowed them down and made them unusable in some cases.

The iPhone 3G received iOS 4 but did not receive many of the iOS 4 features such as wallpapers and multitasking and iOS 4 made existing functionality a lot slower on the iPhone 3G. This was not due to battery degradation but rather due to planned obsolesence. Apparently, some of the issues were fixed on iOS 4.x updates, however.

The iPhone 4 received iOS 7 and missed out on a few features but still had a lot of the functionality. However, in some cases iOS 7 would lag on this device especially when browsing the internet and switching between apps.

The iPhone 4S received iOS 9 and missed out on a few features but still had a lot of the functionality. However, it was unusable. It would lag everywhere. This led to me downgrading my 4S to iOS 8.4.1 by downgrading to 6.1.3 through the signed IPSW and then installing the 8.4.1 OTA.

These are only three cases however and I doubt Apple are planning on deliberately slowing down any more iPhones now that word is out about those three.

Conclusion

So if your iPhone has become slower, unless you’re on a 3G, 4, or 4S, blame your battery, not Apple. They only want to ensure that your phone is reliable and doesn’t unexpectedly shut down.

Apple no longer signing iOS versions other than 13.1.2 and 13.1, preventing downgrades

If you’ve heard of how much of a buggy mess iOS 13 is at the moment to the point where Apple have already released 3 minor updates for it after its release, you may have been planning to downgrade to iOS 12.4.1. But now you can’t.

Apple have stopped signing all iOS versions for iOS 13 capable iPhones except iOS 13.1 and 13.1.2. Why they stopped signing iOS 13.1.1 and kept signing 13.1 is unknown.

Also, for the devices that are now stuck on iOS 12.x versions of iOS because Apple deemed that they are incapable of running iOS 13, iOS 12.4.1 has gone unsigned for them too meaning that only the exclusive iOS 12.4.2 remains signed for those devices.

This means that no signed iOS versions that are publicly jailbreakable can be downgraded to anymore. However, with the checkm8 BootROM exploit compatible with all iPhones from the 4S to the X, that shouldn’t last long.

What iOS version are you currently using on your iPhone and how are you getting on with it? Tell me in the comments section!
