iPads have always had bad standby life. When I had a M1 Pro it would drain 30% in half a day. Not kidding. I would keep the Ultra, it's a far superior device.
My m1 iPad Pro after years of usage on degraded battery health doesn’t come close to this and lasts multiple days. What were you doing with iPad that was draining 60% a day in standby?
 
Logic dictates that between two identical devices (hardware), the device that is exhibiting higher standby drain is simply doing more work in the background that is keeping it from staying in the lowest power state for a longer period of time. The challenge for users who have poor battery life is to determine the software and settings that are contributing to it and evaluating whether the benefits of those are worth the extra drain, so it's great when feedback on potential places to look is given. Posts about having great standby drain are certainly valid in that they prove that better performance is achievable but at the end of the day the variation is still going to exist between different users.

Yeah but draining 60% on standby in a day isn’t logical unless it’s faulty battery. I could leave iPad with cellular in a dead zone trying to connect to network all day won’t degrade the battery to that extent. In fact iPad Pro is excellent hot spot and battery last lot longer than tethering from iPhone.

I'm serious my iPad M1 would drop 20% overnight, 30% over 12 hours. It's one reason why I got rid of it. Not only that but it would take 10 hours to charge 10%. Not kidding. And it wasn't the charger I've tried multiple chargers. 20 watts, 45 watts, 60 watts 100 Watts I have them all.

True, most likely was.
 
Do you have an Apple Pencil attached to it? That little bugger drains my iPP M1 so much that I prefer to keep it deatched. I just hang it on different furniture pieces that are metallic lol.

It's overall unfortunate how much energy it requires. If I write something for a while it feels like my iPad will be down 20% by the time I'm done. Not to mention how it makes the iPad heat up sometimes.
 
I've also been trying to diagnose a battery drain on my 2020 11" Pro recently, and I'm starting to suspect the Pencil as well. I mainly use my iPad when travelling, so it can go days sitting on standby. That's never been an issue before, but 2 weeks ago I charged it to 100% after using it over the weekend, and 2-3 days later it was completely dead. 🙀

Checking battery usage, each day was showing a 20-30% background energy drain from some random app (Mail, Weather, Health, different each day). But once I charged it and detached it from both the Magic Keyboard and the Pencil, standby drain was negligible, as I'd expect (maybe 4-5% each day across several apps). Now I'm experimenting with keyboard attached/Pencil detached, keyboard detached/Pencil attached, both attached, and so on. And the Pencil seems to be the guilty party. Not sure why the battery monitor assigns the energy drain to random apps, mind you. 🤔

All very odd. I've had this Pencil attached to the iPad for years without this being an issue before. Seen some suggestions online that unpairing/re-pairing the Pencil can help, so I guess that's the next step.
 
Weird, I don’t experience anywhere near that level of battery drain on either of mine. I charged my M5 IPP yesterday, left it in my work bag overnight (unplugged), took it to work and about 30 hours later since charging it, first use since charge, it’s still 100%.
