My battery life is noticeably worse with beta 6 on my 15PM. Beta 5 was pretty solid.

I find battery to be quite bad on my 15PM on 18.0 beta 6 compared to 17.6.1.
And remembering the experiences from the past years, I'm staring to be afraid we will be stuck with that. At some point during the beta cycle, battery gets worse and it drags all the way to the public release.
Everyone saying "but a lot of debugging and indexing going on"... yeah, I thought so too. Let's hope I'm wrong and that they will indeed fix it but I'm not too optimistic.

Yeah these betas actually never bounce back fully I don't think. Seems every year I download betas, the batty life takes a drop from the prior iOS version and never fully rebounds. The newly released iPhone in September are the only ones that see the decent battery life.
Clearly the chips and optimization matter a great deal in keeping decent battery life.
Just imagine the hit 15 pros are gonna take on battery once AI is fully released.
You can disable Apple AI if you suspect such a terrible battery life because of these features.
I’m using beta 6 (PB 4) also since this week on my 15 Pro and I think the battery life is „ok“. It’s a bit worse than 17.6.1 before but it’s not that terrible for a beta. For sure there are still a couple of bugs and missing optimizations. When these are fixed until the final release the battery life will get better.
Oh I am not concerned right now as I don't own an iPhone 15 pro. I was referring to @ManuCH post. I have concerns that battery life isn't going to be as good as iOS 17 for all iPhones, but I also suspect 15 pros are gonna take a hit for AI. You can turn it off for sure, but if you want it, it might be at the cost of battery life.
Basically I expect every software upgrade to make my battery life worse and my performance slower. The software is getting more complex as Apple builds new things into it, not less. Yes, they will squash bugs with runaway processes or bluetooth and wifi issues that could offer some short-term improvements, but if you tested and charted every version release and pulled back far on the graph, it's mostly going downward, right? Everyone seems to think that Apple starts "optimizing" code as they get closer to RTM, but they are always optimizing... and they are always adding new stuff. We are already getting rumors of Siri not being finished until 18.4. It's going to be gradual. My battery life will be less. I'm at peace with that understanding.
You don’t want to tell me that the battery life won’t improve at all!?
I have a 15 PM it’s one and a half month old now!
Went on beta train right at the start after I got it into my hands.
I am only getting 5-6 1/2 hrs SOT! With an 15 PM I expected at least 7-8 hrs, better more.
I think they will get rid off that heat issue, and optimize the battery in form of fixing battery draining bugs.
This beta isn’t ready for public release with
that okayish battery life for sure!
And it’s also important that the devs release updates for their apps for iOS 18 for getting better battery life and performance.
If it’s true that my 15 PM won’t get more than 5-6 1/2 hrs SOT I would be so disappointed!
I bought the iPhone with the knowing it’s best battery right now, right now it’s not better than my old 13 Pro!
I will stay optimistic otherwise, why I bought this expensive phone with best battery life of iPhone right now!?

This is partially true. Yes more advancement means worse battery life to an extend, but there shouldn’t be battery drainage issues. I expect that my 14PM wont last just as long as it did on iOS 17, but I don’t expect I should be having to charge in the middle of the day to get it through. I was ending the day with about 50% on iOS 17.5.1. Even early stages of the iOS 18 and up until the last beta 5 I only saw about a 5% drop from where I was. That’s what I would expect, not 20%.
Yeah that’s true, sure the software gets better and more demanding on battery life, I get that.
But yes the drain has to stop before public release and the heat, that causes battery life decrease, has to stop too!
Yep, I would hope beta 7 fixes as the prior betas didn’t have this issue.
For me, battery life on my 15 Pro is as bad as usual with Dev Beta 6 compared to basically every final iOS version.
I hardly make it through the day with only ~4h SOT.

Latest public beta on a 15, experience has been super stable and solid. If the battery is worse the difference isn’t noticeable to me.
For reference, the 17 public beta on my 12 was great too but the 16 public beta was a mess. Took a good quarter out of the battery run time. Also on 12.
Colour me impressed.

Biggest concern I have right now is around heat. When I charge my iPhone 14 Pro (wired or otherwise) it can get incredibly hot. I always expect some heat issues during the beta, but it’s been unusually bad this time around. It’s actually stopped charging many times due to the heat, which has never happened in any previous beta cycle.
Yes the heat is a thing that needs to be fixed asap!
It was better with beta 4 and 5 - only got worse with beta 6, so fingers crossed for beta 7 tomorrow
I found that if you don’t touch your phone during charging, it’s ok with the heat, still not acceptable though
The final release is getting close so hopefully the next few betas will just get better & better. Look forward to the next beta this week 🤞🏻😃
Yeah me too, the randomness of heat is driving me crazy, but charging is better I think.
Let’s hope for better results with beta 7 !
And 14PM here! Been having heating issues on beta 6. It’s been a problem on and off throughout iOS 17 and then got better before beta6.
Nice to see someone in a similar boat. Mine was an AppleCare replacement (broken screens, did express). Never had beta on it, but has been restored twice. I think the batteries are 1. Potentially lesser quality, and 2. More watched since we can see the info on them now.

There is nothing odd. Battery degradation isn't a linear, predictable process. Otherwise everyone would have a similar experience with battery health, and that's not the case.
On my old iPhone 12, the battery health degraded quite fast from 100% to 89% between 10 and 18 months of ownership (approximately), but then remained at 89% for a very long time before dropping to 88 and then 87% after 3 years of ownership. Quite similar experience on my Apple Watch Ultra 1 where the battery health dropped fast to 91% within the first year but then only dropped by 2% more during this second year.
Then replace the battery. You just need to pay for it and insist they do it. They only cover it below 80%, but if you are not happy with your battery life, you can always pay for a replacement.
