If by many posts you mean posts here, keep in mind that MacRumors users tend to overwhelmingly buy pro models. The regular 17 has not really been discussed on these forums.When looking at many posts of bad battery experience after updating I get the impression that most seem to be using a PRO model of the iPhone. That makes me wonder if this bug/issues is related to the 120hz screen "feature" that was released with the 13 pro. Would be interesting to find out if enabling the "Limit Frame Rate" setting makes a difference.
Hopefully Apple will correct this issue ASAP, won't update my daily driver until then (16 pro user).
Edit: Just read in another thread that LPM seem to improve things. LPM disables 120hz.
Please tell us how you get along!I have been on the public betas on my 16 Pro since July and it was never an issue until I installed the final release of ios26. Now it runs hot and I have to be careful in order to get a full day's worth of battery life. I am going to install the 26.1 public beta and see if that makes a difference.
Thanks for posting, this was informative 🌞Don’t look for any other explanation:

LPM seems to help massively, I’ve read several users who struggled with battery life after updating the 16 series.
iOS 26 animations are really abhorrent. You just can’t release an update that kills battery life through everyday animations. It is ridiculous.
Fingers crossed for 26.0.1 that's just released. Nothing mentioned in the release notes about fixes that are related to what you mention tho. Otherwise I guess 26.1 its what we can hope for.My iPhone 16 Pro Max featured very long battery life prior to installing iOS 26. Amazing since I use nearly every feature and capability during long work days away from the office.
Having owned nearly every flagship iPhone since day one, it’s years of experience that allowed me to fully appreciate just how great the battery life and overall performance of my current iPhone.
Then I made a drastic mistake, violating my own personal policy to wait a few months before installation of a new version of iOS.
I installed iOS 26 the day it became available.
Since then no matter what I try, battery life is massively decreased. Resets, clean installs, checking every conceivable setting, leaving it plugged in for days for indexing, while using my backup iPhone. It goes on and on.
If I didn't greatly prefer my 16 Pro Max over iPhone 17 Pro Max I would buy the new model. But I will wait for 18 Pro Max or whatever they choose to name the next model.
Perhaps a future iOS 26 update will resolve this dreadful experience.
It had been a while since Apple impacted battery life THIS much on an original iOS version. That was a solved problem: the newest updatable iPhone was always like-new (or very, very close) on its first major update.My iPhone 16 Pro Max featured very long battery life prior to installing iOS 26.

My Pro 16 is fine no battery issues to speak of. Maybe a reinstall may help or it could be a app?
I was also on the beta train this summer, and had much better battery life than the official iOS 26.0 release. iOS 26.1 beta doesn't seem to be much better for me.I have been on the public betas on my 16 Pro since July and it was never an issue until I installed the final release of ios26.
