15 pro and definitely seeing excess battery drain. I can’t get through a whole day without charging. That’s not common for me at all. I put it on charge at bedtime with 40-50% before.
Got a tip for us?

iPhone 14 Pro Max on iOS 18.0.1 here and battery is very good given the fact i have 87% battery health it still lasts all day
Some iPhone 16 and iPhone 16 Pro users have been experiencing excessive and unexplainable battery drain, according to complaints on Reddit, the Apple Support Communities, and the MacRumors forums. While many of the reports are from iPhone 16 users, older iPhones running iOS 18 may also be experiencing battery life issues.
There is a long-running iOS 18 battery life complaint thread on MacRumors that was started while the update was still in beta, but there have been a fresh wave of complaints following iOS 18's launch and the debut of the iPhone 16 models.
Affected iPhone 16 owners have seen significant battery drain even when the iPhone is not in use. From MacRumors reader T1aaj:
From JulianL:
In some cases, much of the battery drain happens in standby mode when the iPhone isn't in use, suggesting a background activity could be causing problems for some users. Using the phone seems to cut the battery drain in these instances.

From kirbysmartdawg:
There are similar complaints about the iPhone 16 models and older iPhones running iOS 18 on Reddit, and while we always see reports of battery life issues when a new version of iOS comes out, there seems to be a definite uptick in the number of people having problems.
From Reddit user Ok-Interest-6561:
On Reddit, one user did an experiment with an iPhone 16 Pro and an iPhone 14 Pro, and claimed to have used both in the same way. The iPhone 16 Pro dropped to 58 percent battery life within 36 hours, while the iPhone 14 Pro was at 85 percent.
Battery drainage issues are difficult to diagnose because iPhone usage habits vary so much from person to person and from day to day. Impacted users have tried turning off ProMotion, disabling the Always On display, turning off background app refresh, removing widgets, turning off cellular, and entirely resetting their iPhones. Some people have seen improvement with some of these methods, but not all have, and the battery life issues persist for many despite troubleshooting.
Some users reported improvement with iOS 18.0.1 and the iOS 18.1 beta, but software updates have not worked for everyone. It is not clear exactly what's going on to impact battery, but it's sounding like there is an underlying bug that Apple will need to fix in a future iOS 18 update.

100% possible! Why would I lie? Lol.
Some days I hardly use my phone, I'm in front of a computer all day. On those days my 15 Pro was only being used to check a text occasionally or maybe view the weather for a few seconds etc.
Can confirm. 15 PM. On days with light use 95-97% when I put it on the charger at night is not at all uncommon.
Edit: I’m still on iOS 17.6.1. Threads like this one are the reason I delay my updates. Sometimes for quite a while.

Yes I just looked and saw the same thing with flashlight draining a lot of battery like that! Definitely some software gremlins afoot. Hopefully 18.1 fixes those and does not just usher in more bugs.
I’ve had the opposite experience on my 16 PM. It’s the best battery life I’ve ever had on any iPhone, and I’ve owned each one except for the 3GS.
There is a possibility that AI features will drain even more battery.
Every G D year! My 13 Pro experiences poor battery life since my company forced us to move over to iOS18.
This is the number 1 reason I haven't upgraded to 18 on my 14 Pro Max.
I agree with this sentiment. I am glad to hear they are shifting away from yearly iPhone updates. I understand Apple makes money from selling new hardware, but I would love to see them slow down.

I agree. I have to wonder who at Apple decided that the changes to the Photo app was a good idea. Mind blowing that not a single person involved said "uh, that sucks, keep it the way it is".
I've noticed those conversations about battery life on Reddit and there's always someone who says something like, "and that's why nobody should update their phones beyond the year it came out, so an iPhone 14 should be on iOS 16."
MacRumors shouldn't give too much credence to these reports, especially when the complainers are running beta software.

Ah Reddit, the site where more you read and use it, the less informed you are.

I start with a fresh copy of iOS and never transfer settings from backup. It’s something more foundational (lazy, lack of precision on an institutional level)
I said this earlier - pretty much every promise of better battery life is a miss from Apple going back a decade. They still haven’t licked the issue yet and I don’t think they can
The question is rather why Tim Cook didn't see this or intervene. Maybe it's time for him to retire.
I have this problem to with my 11 Pro. Today I took it from the charger and after 1h walking without using it at all the batterie was at 85%. In the past two weeks itb was a lot worse when actually using the phone.
I also noticed, that charging the phone, using the same charger as always, takes a lot, longer. I guess, that is because of high energy consumption while charging, maybe some useless KI process have a lot of work to do.
