Shouldn't the battery saver mode be turned off when the phone is charging?I'll say yes. And don't call Alex--looks like he has his hands full.
What I'm saying is that the orange bar at the top in the OP's picture doesn't indicate the battery saver mode. It is merely a background colour. Go to the Contacts app and tap a contact that has an orange icon (provided they don't have their own avatar), the detail screen pops up - with the status bar in orange.I really have no idea. I'm just guessing.
So I now see what you're saying--that Battery Saver turns the top and bottom borders red/orange. But there is also a Battery Saver icon that appears in the Notification Bar (a battery icon with a plus sign in it), that can't be swiped away. Maybe that disappears when charging?
Answer is No. Both top and bottom should be orange. Not just the top. And it shows it's charging.
