iPhone 16 Pro Observed Battery Drain on Idle

So I have had my iPhone 16 Pro for a few days now, and my friend has got hers last night.

She's on 18.0 and I am on 18.1 beta 5 but what I am about to share proves this is not version specific.

We both observed great battery life when actively using the device, browsing, texting, camera, etc.

However, when it comes to idle, the battery drain is very noticeable.

For me, last night I went asleep at 10pm and woke up this morning at 7am, the battery drain was 30% and every hour there's a different app that accounts for the drain (ranging from the weather widget, find my and strangely youtube, since I don't have a subscription for the membership which enables background playing).

This is strange and it seems to be a case, can any other 16 Pro users share the idle (without charging) battery drain experience?

Mine drained around 20% while on the charger but I might have a defective device. Or there is an iOS 18 bug affecting the Pros in all these weird ways. I'm on the latest 18 general release build, not beta.

This is from my 16PM with 18.0. I have been monitoring it for the past few nights and it only shows Home & Lock Screen for the 6 hours that is it idle, the battery doesnt even drop a single percent which is great. I did have issues on my 15PM in the past with Find My draining my battery overnight so I disabled Find My on my Airpods which resolved the issue. I currently have Find My re-enabled for the Airpods on the 16PM and I am not seeing it show on my overnight battery stats.
