Werid thing, I used Magsafe battery pack to work out and keep the phone charged so it's not wasting the phone's internal battery. In the past, the battery would drain to about 20 percent over three hours.

Today, I noticed after the three hours, that the phone and the battery still said 100 percent, which is impossible. Plugging in the battery gave me a green light on the battery, like it's charged.

I rebooted the phone, but it still says 100 percent Magsafe battery.

What the F? Bug?

Noticed same behavior today. Used MagSafe battery all day long and it is still at 88% like 10 hours ago

I used my MagSafe battery for the first time on a trip, it was absolutely useless. My phone went to 0 and it wouldn't even charge it enough to turn it back on and kept rebooting itself.

The phone was at 50% and went to 0 while the MagSafe battery went from 95-70% in a few hours.

I have been looking for a thread like this.

Similar problems.
Magsafe battery attached and the phone charged for 4% (37 -> 41) and then after some normal use it dropped to 39%

Tried it with 2 iPhones (12 pro and 12 pro max). Same behavior
