iPhone Air MagSafe battery dying in my bag

My iPhone Air MagSafe battery drained down from 100% to 0% in my bag twice now.

Anyone else experienced this? The only thing I can think of, besides it being just defective, is the magnets on my Kindle case are somehow tricking it into slowly discharging over the span of a few days.

From further testing it does appear to be the battery getting activated repeatedly by the Kindle case.

I've put the battery on top of my Kindle on the table and watched it on and off. The light on the back comes on periodically. It's already discharged down to 92% after spending half the day on there.

I guess I'll just have to keep them in separate pockets.
