iOS 18 Battery Life Thread

16PM here. It seems that battery goes down faster than on 14PM and iOS 17.
Home Screen plus Pro Max means the bug is most likely ProMotion not bringing the display down to that 10-24 hz refresh rate range on a static Home Screen. Just burning through battery doing nothing due to the screen not adapting like it should.
If this is the bug, you should be able to get some relief by turning off ProMotion.

I have Home and Lock Screen drain on both my iPad and iPhone. The iPad doesn’t have AOD and I turned off most widgets a few days ago. My iPhone is face down or in my pocket 95% of the time, but Home and Lock Screen has been the biggest drain since I got the new 16 pro. So I don’t think AOD is the culprit.
Pretty frustrating that battery is mediocre.

I had one in the garage that’s not paired to the phone but I just removed the battery from it. Hopefully that was the issue.
My family members don't check battery life & cycle, whenever they need to recharge phone they recharge, they use phone as a phone, without worrying, They use AOD, don't stop any background activities of Apps, After two or Three years either they change battery or phone, Life is simple
But is it an iPad Pro? Just trying to diagnose if my ProMotion theory has any weight.
I had great battery life but for the last day in battery settings it says update finishing in background. What was just released that is taking so long to finish? Had iOS 18 on it. My battery dropped so far 16% in an hour , now 17 as I type this!! That is just the last charge. I had to charge it because of the fast stop before this
Mine was like that. I had to set the charge to 100% (usually keep at 80) and leave it overnight
15PM Beta 5...battery life was better for a few days, now it's taking a nose dive. I have no idea how or why.
EDIT---has anyone figured out what "Home and lock screen ---connected to charger" battery use is? It's using 12% or so of my battery.

My charge is set to 100% the now 25% drop has been mostly on stand by. What is this update that is taking so long, how do I check what was downloaded? I had iOS 18 on it already. No beta software. iPhone 16

Yes, it’s an iPad Pro, so there’s a possibility of an issue with ProMotion.
A part of me wonders if it’s new Apple algorithms designed to support Apple Intelligence that are mistakenly included in this category. However, after searching online, it appears that people have also encountered this issue on iOS 17.
The battery life on my 15 Pro Max stabilized about 5 days after I upgrade to iOS 18. Home & Lockscreen still shows high usage, but most it also says it’s connected to charger.
What really changed is I’m no longer see a 30 degree slope on battery life when idle. It now barely drops.
The 2 orange chunks are when my phone was plugged into CarPlay.

Today I am spending my battery on Balatro. I imagine it will be about 70+% of my usage.
I found out 2 things that stopped the whole battery drain (at least for me) iOS 18.1 beta 5.
1. Mobile Network from automatic to your provider (t-mobile here)
2. disabled iCloud Drive completely (not iCloud!) maybe I had to much data there that the index process had to check up
Now battery life is a LOT better from 80% to 20% in around 5-7 hours (previous was like 3-4) on WiFi full signal
Device: iPhone 15 Pro Max - Battery health 92% and 256 charges
My advice: give it a try!

How was battery usage showing up in the Settings app? Were those items explicitly tagged as causing drain, or was the drain lumped in a random category?
It was showing nothing. A bit Home & Screen
- but nothing else. Like it was a ghost process shown
I also checked my phone with this app and the CPU Process went significantly down from like all the time 15-30-% to now like 1-5% on all cores

Blow is screenshot how it’s now. It’s a lot better (in my case)

Also as you can see. The last 3% were like from 80-76% in about 45min which is quite good for the battery @92%
I am experiencing the exact the same issue. My 16 Pro ate almost 30% battery overnight, and I read in the battery usage that every hour, one from Siri / weather widget / find my would contribute to the most battery usage, and even YouTube, but I have no YouTube membership that enables the background play and the screen was not even on, weird. Running on the latest 18.1 dev beta 5 tho.
After updating to iOS 18 on release day, Photos did some overnight indexing. 2 days later, on Wednesday of last week I left for vacation. Came back from vacation 2 days ago on Tues. Since I’m back home, yesterday Photos decided to operate for 6 hours in the background! Most of it spread during the day. I monitored my battery when I was away and there wasn’t any unusual background activity - could significant locations be a reason?
And is this even an indexing issue? I have never seen the “Ongoing Device Setup” message so I figure my phone is finished indexing.
