For my use case, I find battery life on my 15PM to be excellent. I start the day at 80% and end about 50%. Same usage as the phone it replaced, which was a xs max. The max used significantly more of the battery.
 
I had iPhone 13 Pro Max, replaced it with 15 Pro Max and it is really disappointing that after 2 years Apple is not able to make some reasonable improvement of battery life - that is actually one of the main points of having a mobile phone. The battery life is not even the same but slightly less during the normal daily use. What is the use of adding some megapixels and some secondary mostly useless loudly presented features?

Really careless ... I expected reasonably longer battery life and not just some usual minor "as if" improvements ...
Well just hope the future iPhones don’t get thinner (as one poster on this forum was complaining about) because if they do, battery life will be even worse. Battery life is dependent on how the iPhone is used. Gaming, shooting video, photography, etc will drain the battery quicker. I’m guessing the new A17 chip requires more power to support gaming and other activities.
Turning off WIFI & Bluetooth when not in use helps a lot. Are you constantly browsing facebook or instagram all day? Use Safari a lot? Go to settings and reduce white point to around 30-40%, that’s helps. Turn auto brightness on.
 
This is just a regular problem of linearity with this new chips since box(12+) design.

Basically my wife gets 14.5 hrs out of 15 pro max, while i get 6-7-9 hours out of it cause mine is losing battery at idle more so than i use the phone and screen itself.

If you use constantly then you get “battery’s worth” and if not then you still lose battery but do not accrue use time out of it.
I don't really follow this, are you saying yours and your wife's battery are different? Or are they the same but the use case affects SOT?

Can somebody tell me if this is a good battery drain? 80% battery locked.

That's basically how my iPhone 15 Pro Max has been looking since launch day. Still the same. It also reflects the experience of at least 3 friends who got the same phone.

So either we all got a lemon, or we all have some usage in common that is responsible for increased battery usage.
 
I pretty much get 7.3 hrs of screen time per day which doesnt seem great... usually needs chargning by 5pm daily... lot of it is teams and wallpaper. I feel the pro is the same... wondering by have a max even..

If Apple would stop with it obsession with thin, we could have a larger battery. That is not going to happen. As the circuits gets more and more efficient, they decrease the battery size.
 
Not the max but the 15 pro, at first I was really impressed with the battery life, now not so.
It used to be next morning between 40-50% now it’s down hovering about 20% each day, and not a big user during the day.

or battery tech could become modern and get thinner (give it some ozempic!)

Red Magic 9S Pro has a 6500mah battery and it's only 0.6mm thicker than 15PM, so it's 7% thicker but has a 47% larger battery capacity.
Apple increased the thickness of 14PM compared to 13PM but used a smaller battery, and it had worse battery life even with newer chip.
So it's not about thinness, they just don't want to improve battery life on purpose because people would hold their phones for much longer, Samsung and google are doing the same as well.

Sorry it is about being thin.
