How to Fix WhatsApp Crashing on iPhone

Getting annoyed with WhatsApp since it keeps crashing on your iPhone?

WhatsApp is a messaging app that should be perfectly compatible with the latest iPhones. With this, we expect the messaging app to work without problems. 

Unfortunately, iPhone users have been experiencing random crashes while using WhatsApp

If you rely heavily on WhatsApp for communication, this issue should be addressed immediately.

Today, we’ll walk you through several solutions for fixing WhatsApp if it keeps crashing on your iPhone. 

Let’s jump right in!

1. Check WhatsApp Status. 

Random app crashes can indicate a problem with WhatsApp’s servers. Before tweaking your settings, see if there are ongoing issues with the service. 

You can use third-party sites like Downdetector to check for reported outages with WhatsApp. 


Unfortunately, server issues can’t be resolved on your end. If the servers are down, the best thing to do is wait for the problem to get fixed. 

If there are no issues with the servers, head to the next solution. 

2. Restart Your iPhone. 

Restarting your iPhone appears to be a simple process, but it’s quite effective in solving software issues. 

A restart should reload system resources, resolving temporary bugs in the process. It also clears corrupted and unused data from the system memory. 

If you are using an iPhone X, 11, 12, 13, 14, or later, here’s what you need to do: 

  1. Hold down the Volume Down button and Side button until the ‘Slide to Power Off’ prompt appears. 
  2. Now, drag the slider to the right and wait for 30 seconds. 
  3. Press the Side button afterward to turn on your device. 
Restart iPhone

For older models, follow the steps below: 

  1. Locate the Power button on your device. 
  2. Now, hold the button until the ‘Slide to Power Off’ prompt shows up.
  3. Drag the slider to the right and wait 30 seconds before turning on your device.

Try using the messaging app and observe if you’ll still encounter random crashes. 

4. Check Your Connection. 

Slow or unstable internet can also cause WhatsApp to crash. Since you are using an online service, you’ll need a stable internet to avoid issues. 

Run a test using to measure your connection’s bandwidth.

If the result indicates a problem with your internet, you have to power cycle your modem.

  1. Go to your router and remove its power cable from the outlet. 
  2. Wait for 5 to 10 seconds. 
  3. Reconnect the power cable and wait for your router to initialize.

Re-run the test on your network to check if the problem is solved. If not, contact your provider to report the issue. 

For mobile data users, check if your phone has enough signal. A 5G or 4G icon should appear beside the signal indicator to be able to use online apps without issues. 

Consider moving to another location to get better reception from your network. 

5. Update WhatsApp. 

Faulty versions of WhatsApp could also be why it keeps crashing on your iPhone.
