iOS 18 Battery Life Thread

I have a 16 pro max and the pattern I am observing is high screen idle. Comparing this to my wife's iPhone 16 pro which is less and she has much better battery life than what I am getting on a pro max. Just cannot work out what is causing the high idle times
Sigh... iOS 18.2 on a 16 Max and my battery life is already at 92% after pulling it off the charger at 5AM.
I did nothing different today from any other day and its usually at 98% at this point in my day.

Maybe it needs some more days to settle after the update? It was on Tuesday, so not that long ago…
Have a look in the battery section, might be a square with info there saying its doing "background stuff"
Mine has been draining after updating to 18.2. Especially if I use image playground, optimization does not seem good here.
Any use of an AI tool is going to cause a lot of battery drain as it’s doing it locally. It’s extremely computationally heavy.
With the first larger-screen models, the battery life was insanely good.
I've done lots of tweaks on my iPhone, turned off background app refresh for many apps, etc... but I'm not finding the cause of faster than normal battery drain on my 16 Pro Max. It's not horrid, but feels like any other iPhone as opposed to the usually exceptional battery life of the larger models. The battery settings give me no useful info on how to fix it.
Between Siri and now this, and after 17 years of using the iPhone, the decline in certain aspects is becoming noticeable. I still love iOS and Apple products or I wouldn't have stuck with them for this long, and I know we hear this constantly around here, but this year I'm starting to agree with those who think Apple is backsliding. That doesn't mean iOS is bad or Apple is bad, I just notice a fundamental quality deficit in things that used to always work just fine. This AI-driven "smarter" version of Siri is as dumb as ever. How can it keep context between requests when it can't even properly play a playlist? Siri for hands-off music control has always been my favorite use case for the feature, and it absolutely sucks right now, and is getting worse.

I did not have the excessive battery drain on 18.1 public release ai features. And the battery drain I am experiencing is not only when using AI, it has significantly increased after 18.2 update days ago.
Can anyone share some info on the battery life for 13pm and 14 with 18.2?
I am using both, the 14 is my "work" phone and also test-bench for iOS before I apply it to my daily driver, the 13P (not max).
Both devices are working great, I think this is the best iOS 18 version when it comes to least "stand-by" drain.
Haven't had a chance to run the 13P on mostly cellular so can't say much about the cellular performance, but did some traveling the other day on cellular for a few hours and didn't notice of any difference in performance good or bad.
The infoscreen "update finishing in background" has been displayed for quite some time, but disappeared yesterday afternoon. Not sure how much or if it impacts battery performance at all. Prob depends on what it needs to update I guess.
Providing some 13P screenshots below, this is mostly on wifi, say around 80% wifi and the rest cellular.
Tbh, not sure why apple music is on my list, I don't use it at all.
What I noticed is that if I use my phone continuously it consumes approximately as much as another but if I make small use from time to time then it consumes more than an identical phone but with another iCloud account….
So it seems that there is a process or some kind of synchronization with iCloud but I don’t know which one.

I was having issues with the battery life as well. I tried everything without result. But on Thursday I noticed that system services were trying to obtain my location constantly. I disabled significant locations and “find my” and battery life on Friday was much better than any other day. I know it’s not ideal, but at least I have one guilty.
Now I have to investigate if there is something wrong with my find my configuration as it’s not normal that the service requieres to know my location constantly. I’ll keep you posted. My guess is that the “left behind” feature is consuming my battery but I need to do more research.

Hi, after the horrible experience with iOS 18 I decided to do a clean installation of my 14 PM configuring it as a new phone from my Mac, then I activated my iCloud account (without backup). He's behaving like never before. He is doing 4-5 hours of SOT using only 50-60% of the battery (I charge it exclusively from 20 to 80%). I'm happy with my phone again. I don't think it will update by OTA in a long time except security update. In case anyone is interested, I follow step by step the settings recommended by the youtuber Payette Forward (In this screenshot it appears that it was loaded up to 85%, my Watch did not notify me and went up 5% more than I like). Excuse my translated English. Greetings to all.

Has anybody a working solution for battery drain on a 16 pro Max? On 18.2, my wife has a 16 pro and hers was charged to 90% this morning and mine to 100%. In the UK here at 21:00 and mine is at 20% charge and hers is on 50%. Really cannot work out what is causing the drain. All I see is high screen idle times. 4 hours 51 screen active and 1h 59 screen idle.
Similar behavior here. If I use the iPhone 16 Pro Max iOS 18.2 continuously, I get quite good runtimes of 80-20/10% with around 7-8 hours of active screen time
However, if I only use the iPhone sporadically every few hours, the battery seems to run out faster and I usually go from 80 to 20% after 4 to 5 hours
Is it because of the iCloud? Unfortunately, I don't know in my case
