I think I’m gonna try this one. Two of my friends have bought it. I’m
done with my iPhone 7. Yesterday I just shot some snow-covered landscape
pictures, and it turned off with no reason. I thought it may because of
the cold weather as it always, so I put it in my pocket for a while and
warmed it up, and then turned it on. And as expected, it powered on
successfully with 50% of the electricity. Very annoying.
