When Samsung debuted its quartet of Galaxy S10 smartphones last month, one of the big talking points was the punch hole camera design the South Korean manufacturer employed in order to get as much screen real estate on its devices.

Since the launch of these new smartphones, developers have been finding interesting ways to make the most of the punch hole cameras, turning it from an eye sore for some, into a nifty little feature.

For the most part it has been weird and wonderful Galaxy S10 wallpapers that have done the trick, but now there’s another ingenious app on the market that could make watching your battery life go down a bit more fun.

The app in question is called Energy Ring, and it certainly lives up to the name.

Developer IJP, which has a number of battery monitoring apps for Android, uses the front facing punch hole camera on either the Galaxy S10, S10+ or S10e, and wraps a slim strip of light around it.

As your battery life goes down, the strip of light changes colour, and therefore provides a more interesting method of monitoring than the standard battery bar that Samsung’s UI employs.

The basic version of the app is free, and offers up a few customisation options, such as adjusting the width of the strip from one pixel to as large as a “donut”, the developer notes. Added to this is the ability to toggle it off when using other fullscreen apps, as well as assigning any colour options you want.

Lastly, IJP says Energy Ring draws nearly no CPU power, as it only appears when the phone is unlocked or woken up.

At the moment Energy Ring is only availably on Galaxy S10 branded devices, which is a pity considering more manufacturers are going the punch hole camera route at the moment. Hopefully IJP has a version of Energy Ring in the works that’s not dependant on specific Android phone makers.
