Ulefone Armor 33 Pro Review: 25500mAh Battery Beast Tested
What People Say
The battery life is insane; I went four days of heavy GPS use and still had 20% left.
The build quality feels like a tank. I dropped it on a gravel path and there wasn't even a scratch.
I love the rear screen! It is so convenient to check my messages while I'm working without having to wipe off my screen.
