A slow iPhone® is more than a minor annoyance—it's a major roadblock. Especially if your device is taking its time to do, well, anything.

Why is my iPhone running so slow?

Ever wonder why your iPhone isn't running as fast as it used to? Here are a few speed bumps that might be slowing you down.

Storage is full

Photos, apps, downloads—all of these files take up space. When your storage is at max capacity, your phone can start running slowly. 

Poor battery health

Your iPhone's battery can start to wear out. A tired battery might not just mean more frequent charging; it can also lead to sluggishness, overheating, and crashes

Frozen applications

Apps are great—until they're not. They can freeze, move between pages slowly, and everything in between. 

Poor network conditions

Poor network connections can make even simple tasks like browsing or sending messages feel like a marathon. 

How to speed up an iPhone that’s running slowly

It’s common for devices to slow down over time. However, there are a few ways you speed yours back up.

Increase storage

It might be time for a digital declutter. Offload unused apps and give your photos a new home in the cloud or on a computer. You’ll notice a little breathing room can go a long way.

Close frozen applications

When an app freezes, double-tap your home button or swipe up from the bottom. Swipe the apps away then try opening them again to see if your iPhone continues moving slowly. 

Improve network signal

Sometimes your phone’s network signal—or lack of one—can be the problem. If that’s the case, sometimes a simple reset can help. 

  1. Open Settings
  2. Turn Airplane Mode on and off or disconnect the Wi-Fi. 
  3. Make sure Airplane Mode is off and test your phone speed. If you have internet access, try reconnecting again.   

Still stuck? You might just be in a low-coverage zone.

Replace the battery

The battery inside your iPhone could be to blame—or at least putting a strain on your phone. When your battery starts to fail, your phone starts to feel it in other places, like processing speed. Check your battery health and determine if a battery replacement is just the thing your iPhone needs. 

If you've tried these steps and still need a little help, we're right around the corner. Schedule a repair at the nearest uBreakiFix® by Asurion store and our certified experts can get your device back up and running as soon as the same day.
