Probably, there are two such batteries inside
The Honor Magic V2 smartphone presented yesterday turned out to be unique. Not only is it the thinnest foldable smartphone and one of the lightest in its form factor, it also packs a 5,000 mAh battery, more than the competition. And in the photo below you can see this same battery.
As you can see, this is a very, very thin battery by the standards of smartphones. Actually, the battery of the Magic Vs model had the same capacity, but the thickness of that smartphone was higher.
The super-thin Honor Magic V2 received a super-thin battery.
