iPhone 12 Pro Does your battery drain 1% every hour on standby?

It seems my phone isn't behaving like my previous iPhones. I have a similar post about battery standby overnight.

No. Check your background tasks. You can see what is running screen off in the Settings->Battery screen.

If you have been busy before that, it might, as apps are still performing. However, over the course of a day it should not (that would indicate a 24% drop in a day, which sounds too much).

This was what happened. I got mine yesterday. After setting up by transferring data from my old phone, I fully charged the 12 Pro. At 10pm, I went to bed with the phone at 100%. The following morning at 7am, it was 99% which is very unusual for an iPhone. I used my phone for an hour watching YouTube, updating apps, checked socials. At 9am, it was 91%. I left my phone on the bed with no apps running in the background, wifi and Bluetooth turned off. By 11am, I was shocked to see it was already 88%.

Doesn't seem to be too unsual to me to be honest. It obviously only lost 1 percent in the 9 hours at night. That's why I meant you'll need to observe this for some more time.
The percentages are also rounded and approximations. Let it sit somewhere for a few more hours and see what happens.
