I’ve had this iPad Air 4 since January (somehow I got unlucky and the first iPad Air I got from December got dropped in the airport with Magic Keyboard case on and it jammed the power button 
), and ever since, I’ve drained about 5-10% of battery overnight and I can’t figure out why.
I have background app refresh off for most of my apps (I’d say about 80% of my apps), and I always have DND on from 9pm at night to 7am in the morning. I checked my battery health via the CoconutBattery app on Mac showing me about 150 cycles on this iPad (I use it a lot), and this is with me running iPadOS 14.4, 14.5, 14.6, and 14.7 and still hasn‘t fixed it (I’m currently trying out the iPadOS 15 Beta at the moment and still has mysterious battery drain).
I try not to charge my iPad when I don’t need to, which is why I care so much about it draining overnight (most of the time when I have around 50% or more of battery, I just save for the next day unless it is going to be a heavy day of usage).
Since I’m on the iPadOS 15 Beta, I’ve been using low power mode to get me by for now, which brings me total drain down to 2-3% lost during the night. Any suggestions that may help me lose less battery overnight/long standby time?
Edit (July 24, 11:07pm CST): I found something about a ”Sidecar” background activity task (see my other thead for more detail) which shows 90 hours of total background activity in the past 10 days, EVEN WHEN I really haven’t touched sidecar for my personal iPad Air 4 in at least a month.
