With our Free Health Check, in any store, we can test your smartphone's battery and performance within minutes. If we find any issues we can offer a range of repairs to get you back up to speed, even if you bought it from somewhere else.

What's in our Free Health Check?

Battery

Your smartphone's battery gets weaker the more you charge it. Our team can check your device battery and let you know if your battery needs replacing.

Apps

Applications running in the background can cause poor battery performance. We can tell you which applications are using the most battery life and show you how to close them.

Connectivity

Leaving on Wi-Fi, Bluetooth and GPS connections on when you're not using them can drain battery life. We can show you how to switch them off and help your battery last longer.
