Thanks for the kind words — and apologies to your wife 😅 We didn’t mean to become a surprise 6:45 AM alarm clock, especially on her side of the nightstand. Tip: you can set a Quiet / Do Not Disturb time in Settings to silence battery alerts overnight. Bonus: fewer notifications, better sleep, happier marriage 😉

Not helpful. I have something draining my battery, and this doesn't show anything that the built-in monitor doesn't. It shows something off-screen draining, but doesn't say what it is. So it doesn't show anything I didn't already know. The app history randomly drops its recording and displays all lightning bolts, making all data it's collected up to that point useless. There's just no reason to use this because it just displays the same info as the built-in monitor.

Hi Shaun—thanks for the feedback! The off-screen drain shows total background use over time, not individual apps, to help spot what’s normal vs abnormal. When you start charging, measurements would get distorted, so history switches to lightning bolts. We’ll work to make this clearer. Best
