That's what I think, too. I think it's kind of admitting these iOS versions just use more battery and that's why bigger batteries and a more efficient chip don't translate into a gain in battery life. The battery iPhone 13 Pro Max was getting on iOS 15 hasn't been matched yet. The 14 series wasn't worse on paper but iOS 16 in real usage made them last less than the 13 series.
Same with my 13PM, battery was best on IOS 15, it got worse every version of IOS 16. Hopefully better in IOS 17

iOS updates have always worsened battery life, but the funny thing is, Apple actually recommends updating to have the best possible battery life. Hilarious.

The actual physical battery isn't adjusted by software. The calculation is simply software figuring out where the battery is.. so if one has had an iPhone for 7 months and it used to show 100% battery life, it was a miscalculation. No battery stays 100% for months.

I'm thinking battery calculations improved and became more realistic with iOS 17, and besides.. the lower the software reports where the battery is (80%) the faster Apple will be willing to replace it, if one keeps the same phone for as long as it takes to get there

PS - iOS 17 is reporting 89% on my iPhone 14 Pro I purchased last year day one. This year's day one purchase arrives Friday! I expect it to be 100% for three days, and below 90% by the time the iPhone 16 lineup shows up..

I think I got the most efficient one. The update having a different vibe. My experience is better than previous iOS, I actually do photo edit on my phone.. it's taking really less time than ago. However, I'm really satisfied.

Battery stats are erratic now, on my 13 mini, with iOS 17. Periods of time have just disappeared from settings. There must have been changes here because the now updated battery alarm app I use only reports intervals in chunks of five percentage units. All in all, I don't experience any worse battery life, so this might just be minor things.

Edit: My 13 mini showed 90 % for a very long time. After a restart it showed 92 %... There is something weird going on here.

Not sure if this has been brought up previously...

If you are running macOS Sonoma and iOS 17, and are using the new widgets on the Sonoma desktop, AND the widgets are "iPhone widgets" (versus Mac widgets), watch out for some noticeable increased battery drain on iPhone. For example, I added an iPhone widget from my favorite snarky weather app (a radar widget) to my Sonoma desktop, and the battery drain on iPhone was noticeable. Fortunately, Settings / Battery / Last 24 hours clearly showed the weather app with a high percentage with "Widget, Background Activity" indicated. Deleting the widget off the Sonoma desktop and sticking to just Mac widgets took care of the battery drain. Just FYI.

I’ve seen a sudden improvement in battery life today too. 🤷🏻‍♂️
Odd that it’s taken a week since installing 17RC to settle down. Hoping 17.0.1 continues to be an improvement, see how it looks this evening. One thing that hasn’t changed is my battery health since starting 17 beta.

My battery life improved a lot with the RC and it has been fine since then and I am no longer that rapid drainage during the day. It seems to as good or better than ever and the previous beta issues are gone. I continue to use low power mode at night though.

I'm not seeing any improvement on my 13 Pro Max after updating to 17.0.1.
All my apps are updated to latest versions and battery life is still as bad as it started to be since beta 7.

In terms of battery life, this phone on iOS 17 is definitely worse than my old iPhone 12 Pro used to be on iOS 14 which should speak for itself

I’ve tried 17.0.1 and I ended up rolling back to 16.6.1 on my 13 pm. Battery life has been once again phenomenal. Can’t say I miss any gesture really.
One things I’ve noticed in 17.0.1 is the find my being always on the battery consumption . Small percentage, but it’s there. This is not happening on iOS 16.
