iOS slow speed troubleshooting

Some decrease in speed is expected when using a VPN. Feel free to take a look at our article where we have described potential changes in your connection speed.

If you have noticed, that the connection speed has decreased more than it should, try adjustments below.


  • Test the speed of several different locations.

    Even if you have used the Fastest Server button previously, you should try several other locations as well. Try the ones that are closer to you. 

    If you're not sure how to check if the speed has increased  - you may find many apps on the App Store for testing the speed. You can download one and use it for speed testing purposes.

  • Change the current protocol on the Surfshark app.

    Go to the Settings page on our app and scroll down until you find the Protocol setting. By default, the protocol must be Automatic. Change it from Automatic to OpenVPN (UDP), then connect to one of our servers and test the speed again.

    If OpenVPN (UDP) does not help, try the IKEv2 Protocol as well. 

  • Disable interfering apps.

    If you are using some file-sharing or cyber-security apps, temporarily turn them off. Test the speed to see if that affects the performance of the Surfshark connection. 

  • Switch from Wi-Fi network to Mobile Data (or vice versa) and see if that affects the speed.

    Some networks might be performing worse with VPN compared to others.

  • Disable the Low Power mode if you have enabled it previously.

    Go to Settings > Battery and check if the Low Power mode is turned on.

  • Reboot your device.

  • Reboot the router.

 If none of the suggestions above help to increase the speed, do not hesitate to contact our Customer Success Sharks and they will help you out!
