Why iPhones Slow Down After A Software Update

If you’ve updated your iPhone to a new version of iOS and felt like it became slower, you’re not alone. Apple’s been accused of slowing down older iPhone models to get more people to upgrade, but that’s not actually what’s going on here.

I’m still on an iPhone 7. I had the battery replaced a year ago, and I make sure to leave at least 20GB of storage available.
With these measures it continues to be pretty snappy, even on iOS 15.4.

Actually, some people recommend you change the battery on your iPhone ever 30-36 months. Also, be aware that if you upgrade to a new iOS version, your phone may be "reindexing" certain code for a couple of days as a gets used to the new version of IOS, causing slowdowns. If you phone is still lagging after a couple of days, it may be time to get a new battery installed.

For me it seems like my iPhone gets faster after the software update and run even smoother

Has Apple ever heard about software optimization? They can easily optimize their OS to demand less power from the battery if they want to. You don't have to defend every Apple decision. I own 4 Apple products but still don't get their actions sometimes, like removing charging brick from the package.

Maybe instead of ‘your battery and hardware can’t meet the demands of newer operating systems’ it should be that newer operating systems don’t demand so much from your processor. I understand that technology progresses quickly, but it’s ridiculous that a processor made 3.5 years ago like the A12 Bionic would struggle to keep up with running iOS 15.

I don't see any lagging on my original SE running iOS 15.4. Actually, it gets better with every update!

"which is free if you have purchased apple care plus"-🤣🤣🤣 jokes like these

While I love these short and to-the-point videos, I really miss the old style videos that AE made. I definitely missed what the reason for the change was but I wonder what those videos would look like today.

*Replacing the battery* is the most optimised solution to this problem!

This is exactly the reason i always hesitate upgrading my OS to the new versions both for MAC OS and IOS.

They weren't "accused" of slowing down older phones. They did. They got sued. They lost.

But a lot of the new features with the updates can’t be utilized on older iPhones so it shouldn’t be related to battery health.

Guys, to keep your battery life healthy for as long as possible make sure you never let the battery lower thant 20%. Charge it!

I did an experiment with my iPad Air 2, I let it on iOS 8.4 until the App Store closed for iOS 8. It was running perfectly, like day one, even 5 years later.
When the App Store finally closed, I updated to iPadOS 13, and it suddenly got A LOT SLOWER. Full of stutters, considerably slower to open anything.
So yeah, big annual iOS updates do slow down your Apple device, considerably so by the time the latest ones comes out.
And it's not battery related

My mom’s iPhone 6s is running on the latest version iOS. That’s 7 years of software support, I commend Apple on doing this. When we had her battery replaced it was pretty snappy like you said, although her battery levels have come down again but it’s still as snappy as my sister’s new Android phone and actually more reliable than that. I always knew that it was battery degradation and actually liked the fact that Apple slows down the phone if the battery has degraded badly, that way it won’t have a hard shutdown like other phones do when their battery is degraded. This was actually done in hopes that it would keep the phone running for longer with the same battery so Apple was actually trying to make the consumer retain the phone for longer not the other way around. Sadly they were accused for the opposite but in return we got more transparency for our battery health which is nice.

This is such a great channel. I always learn valuable new things. Thanks, greg! 💜

After updating to iPadOS 15, my iPad 6th Gen felt slower, overheated so quickly and had worse battery life. So, I did a factory reset. After the factory reset, it became much faster and smoother. I tried performing a Browserbench Speedometer 2.0 and the score nearly doubled.

personally I use iOS 13.4 on my iPhone SE 2020 with 89% battery health and it is a performance KING
