It’s not bad I guess but not amazing. Pro Max devices should do better!

Yeah me too, but I guess now I have to wait for about 3-5 days until everything settles down with my new install of iOS 18.

Yep! Not expecting tomorrow’s release to be a new build but you never know.

Aw big Yes , you are absolutely right.. It really could be worse 😅 And how many more users would be dissatisfied after tomorrow's update 🙃😁
 
I have to say I've never ever complained about battery life ever, but on the 18 betas it truly is horrific. It drains like machine gunned alcoholic.

For the first time in years and years, my iphone 12 pro died and needed recharging. Abd everyday it hits red with normal use by night time. This has never happened before.

Sure hope the final release sorts it out.

well, my iPhone 12 mini has gone from bad to worse in battery. I don't know if it's indexing something in the background and that's why it drains so fast, and it may improve I don't know, all I know is, I'm now charging the phone nearly 3 times a day and my battery health is 76% that dropped massively from 84% from the last two updates. I honestly can't figure out what is going on with these devices anymore. My iPhone 8 with 64% battery health holds better... older system. Makes no sense. I'm really in dire need of a new upgrade but at this point, I'm honestly not sure about the 16 pro either. But i guess anything is better than what I have at this point. My Mini 12 is the one banned in some countries due to radiation leak or whatever. So I do need an update also got tired of the small screen

What version did you upgrade from?
 
I noticed that Photos went through a full re-index/analysis after upgrading to iOS 18.

So yeah, battery would take a hit - in addition to what you normally experience with a full version upgrade.

Sounds plausible, sort of expected that but now I feel it's draining extremely fast. I ought to do an entire clean wipe of this phone and start again but gods that's rought

If you do a clean wipe, restore a backup it might be a case that you still will have maintenance work that has to be done so don't see that it would make much of a difference.
What I normally do is to update the device in the evening and keep it in the charger for the night. If there would be any maintanance or background work done its done while I'm asleep.

I have already noticed it sometime before, and I wrote it out loud here, its true that iOS 18 works much better on old phones than any iPhone 15 series phone..mysticism

Works great on my base 15 actually. I think it is the 15 Pros with the 3nm processor that have some issues. Hopefully the 16 and 16 Pros with the move to the second gen 3nm fix whatever is going on since Apple says the 16 Pro Max is the best battery ever.

Seems like that reinstalling iOS 18 went good for me.
Heat is less than before, battery drain is more than before (guess it will settle down in a few days), all in all it’s a good result it feels like.

try to see if indexing isn't draining the battery and see if in a few days it's not improved...
 
Does anyone else notice on the past few betas that while the screen is on there’s little to no battery drain ….but then I sit my phone down and pick it up a few minutes later it quickly drops 2%-3%?
 
Had zero battery loss last night ! Stayed at 95% the whole night.
Great!
Now only the battery needs to get a bit better while actually using the iPhone
