So, the Ulefone Power Armor 13 is the company’s rugged smartphone with a huge battery. It has a red-colored custom physical button on the left-hand side. You can assign a range of functions to this key.

There are 6 different functions to choose from, and you can pre-set it for a single press, double press, or long press. For demo purposes, Ulefone assigned a single click for Sound Recording, and then reassigned it to a Flashlight function, just to show you how to do it.

You can also choose to activate an app with one of these functions, if you want. For example, you can assign a double click to activate YouTube, or your phone’s camera.

All of this is really simple to do via the Settings. All you have to do is open your phone’s ‘Settings’, and scroll down to the ‘Custom Key’ submenu. There you have options to set actions for a single click, double click, and long press functionality.

Having a physical button that you can utilize any way you want is a really nice feature. Smartphone OEMs started implementing such functionality a long time ago, but it’s nice to see Ulefone is still sticking with it.

The device includes a truly gigantic battery pack

The Ulefone Power Armor 13 comes with a 13,200mAh battery, and it’s a chunky phone, needless to say. Still, if you want a rugged device, which you don’t need to charge that frequently, and which can take really intense use, this device may be just right for you.


The phone also includes a 6.81-inch display with a hole punch, and a 48-megapixel main camera. It comes with 8GB of RAM and it’s waterproof, dustproof, and shockproof. Android 11 comes out of the box, while the device supports 33W wired charging, and 5W wireless charging.
