iPhone Slow? What’s Up with iOS 8 Performance

Why is the iPhone Slow? Is Apple sabotaging my old iPhone so I’ll buy a new iPhone 6?

These are two questions I’ve heard repeatedly in the last 24 hours as the iOS 8 release delivered dozens of new features to devices as old as the iPhone 4s and iPad 2.


Here’ a look at what’s up with complaints about a slow iPhone and how you can try to fix your iPhone slow problems without buying a new iPhone.

Every year there are people who ask why is the iPhone slow after updating and is this a conspiracy. Here’s what’s up with your iPhone.

After the iOS 8 update, "Why is my iPhone slow?" is a common question.

Slow iPhone issues on iOS 8 aren’t limited to older devices, we’re hearing from iPhone 5s owners who think the iOS 8 update slowed down their phone leading to apps that don’t load right and other iOS 8 performance issues.

This is something that happens every year when Apple delivers a new software update for the iPhone. If you look at the trends there is an increase in searches for iPhone slow n every month where Apple releases a software update.

iPhone Slow: iOS 8 Conspiracy?

Is Apple really slowing down your iPhone so that you’ll want to buy a new iPhone 6 or iPhone 6 Plus? The short answer is no, Apple doesn’t want to ruin your iPhone.


The longer answer is for some users a search for iPhone slow is justified. Data shows the iPhone 4s is slower on iOS 8 than it was yesterday on iOS 7.1.2. This is something Apple may fix in an iOS 8.1 update months down the road, but if you are using an iPhone 4s you may want to wait.

Why did Apple offer an iPhone 4s iOS 8 update if the performance isn’t as good? Look at it this way. If Apple did not offer an iOS 8 iPhone 4s update users would complain that the company doesn’t care and is keeping features from the three-year old phone to force users to upgrade.


By offering an iPhone 4s iOS 8 update with most of the iOS 8 features Apple allows the owner to choose features or performance. You don’t need to install iOS 8, you can stay on iOS 7.1.2 forever, or until the iOS 8.1 release arrives.

I was nervous about moving up to iOS 8 because older devices typically struggle with new updates. However, so far, the iOS 8 experience on my iPhone 5 has been on par with the experience in iOS 7. I haven’t noticed any lockups, the animations and transitions between apps and the home screen are fluid, and it’s still extremely fast especially for a two year old phone.”

So What’s Up with Slow iPhones?

If you’re using an iPhone 5 or iPhone 5s you may still think your iPhone is slow. This isn’t surprising. When something changes we key in on certain things and with new features and options the iPhone 5s may seem slow.

Right after you update to iOS 8 the iPhone needs to run through a lot of background tasks to get everything running right. For a short period the device may really be slow. Give the device a few hours before you call iOS 8 a bust.

Rene Ritchie of iMore explains the rest of why you think the iPhone is slow after an update,

“And perception, as the old saying goes, seems like reality. Likewise when you update to a new version of iOS, you know you’re changing things and you become more sensitive to change. You’re looking for what’s new and what’s different so any little tick, pause, or skip tends to stand out.”

How to fix a Slow iPhone on iOS 8

You can fix a slow iPhone in several ways. There is no one solution though, so you may not end up with a complete fix until Apple delivers an iOS 8 update.

Easy Solution

The first thing to do to try to fix a slow iPhone is to reset all settings. Sometimes an iPhone setting goes haywire and causes all kinds of problems. This does not delete your apps or data, but you may need to re-enter WiFi passwords.

Go to Settings -> General -> Reset -> Reset All Settings -> If prompted enter your Passcode and confirm.

Wait a few minutes for the iPhone to restart with settings back to factory specifications.

Next Level Solution

If iOS 8 performance is too slow after waiting a day or two and resetting all settings you may need to perform a clean install. This involves restoring the iPhone to factory settings. This wipes all of your data so make sure you back up. The best solution is to add all of your apps and accounts back manually, instead of restoring, but that’s more work than many users want to go through.

After you back up go to Settings -> General -> Reset -> Reset All Settings and Content -> Enter a Passcode and follow prompts.

After a short period the iPhone will be like you took it out of the box and you can restore or set up as a new iPhone. This process takes a little bit longer so don’t do it unless you have an hour or so to reset and get back up and running.

For a very limited time Apple is still signing iOS 7.1.2, which means it is possible to downgrade from iOS 8. This hole will close any day now, so make sure there is a yes next to your device on this page and then follow these instructions to downgrade from iOS 8 to iOS 7.
