Ok so the windows team decided to make icons' lines thinner. Seems like a quite nice idea, this may look stylish. Well, then why on the earth they changed the battery icon to some strange nineties looking fat crap?
It's the battery icon from Windows 10 (desktop). Shoehorning desktop stuff onto a mobile OS = garbage. The wireframe/hollow icons are a mess on mobile as well. They're harder to see and fall apart on lower resolutions.
