Battery lives longer or charge holds longer ??
iOS 27 is rumored to be focused on bug fixes and performance improvements, and this should result in "longer battery life," according to Bloomberg's Mark Gurman.
In line with his previous reporting, Gurman today said Apple is "making performance improvements aimed at extending the battery life of the iPhone," but he said it is "unclear if Apple will quantify how much longer devices will last." In other words, it remains to be seen if Apple highlights the battery life improvements during its WWDC 2026 keynote this Monday.

There’s a correlation between the two. Better battery life results in few charges. Few charges results in better battery life due to use degradation which means the batteries last longer. Roughly speaking of course.

The battery life with my iPhone 17 and iOS26 is noticeably worse than it was with my 13 Pro an iOS18. I am trying all the tricks even forcing the phone to 4G. But nothing seems to work. Just using Safari (especially on some web pages like Macrumors and Reddit) makes the phone run warm or sometimes hot.
Wife is using 16Pro Max and has observed the same noticeable decline in battery life after iOS26. We are now traveling for a month and this bothering us even more than in home. (Lost two percent writing this in dark hotel room with screen brightness turned all the way down).

So you're saying...
A reduction in the battery discharge rate results in fewer charging cycles which should result in longer battery life.

She's getting married July 3, so she's probably been super busy and can't be bothered to write iOS code for a while.

If it doesn’t have to work as hard to do the same thing then of course that will translate into better battery life. But we’ve seen tech companies squander improvements in efficiency 100 times. I have no doubt this will be better for about a week before they ruin it with something else.

Funny thing, or not so funny thing, depending on your point of view... my 15 pro has about the same charge cycle requirements as my former iphone, the 12 mini... I don't use the newer one differently, and don't do anyting on it the mini could not do.... i guess the fancier screen and 'improvements' are countered by the bigger battery....
So better battery would be good, on a phone that spends 23.5 hours a day sitting on its dock doing nothing for the vast majority of the days, yet still needs to be charged every second day (I don't leave it on charge all day... just turn on the charger when the bettery is around 20%)

My iPhone Air still gets great battery life. I finish the day with about 40% with no top-ups. But I'll take it!

More efficient software would mean less power is needed for the same tasks. Saving energy on the scale of millions of iThings would please Mother Nature and reduce peoples' energy bills
In other words Apple should always have been doing this

And people should turn their lights off when they leave the room (even for LEDs), drive more gingerly and drive less, and so on and so forth. When all of the above happens I’ll agree Apple hasn’t done their part to optimize their software. Otherwise it’s real easy to throw stones.
Doesn't Apple say this for all iOS versions? And then it turns out it's never true? We'll this time I guess

Really?
What happened with the much-ballyhooed, AI-powered 'Adaptive Power' ?

I think the problem with iOS 26 was redoing the entire os design in Liquid Glass would destroy battery life and probs out paces the benefits of adaptive power mode.

But hopefully by re-writing existing features, removing old useless code.
They might surprise us in a good way this year.
I’m on 26.6 beta 1 and battery seems to have been decent

Unless Apple reverts the battery settings to something like in iOS 18, I doubt they are serious about extending battery life.
As it stands in iOS 26, the battery pane is the single most consumer unfriendly design they have released in a long time. Being able to see what process has how much of an energy impact in any given hour to troubleshoot the causes for battery drain yourself is, or has been, a pro feature.
So I’m their right mind thinks comparing battery usage to the day prior is representative of anything? Especially when not using precisely the same apps everyday.
My guess is they had to change it because iOS 26 is such a battery hog and they didn’t want to risk snitching on themselves. So hopefully that starts to end again on Monday.

You mean the feature that tells me it will adjust performance on my phone right after unplugging it in the morning?
I suspect as it is it is going down the drain like the intelligent reverse colors feature, which was later replaced by proper Dark Mode in iOS 14.

That’s not entirely true. iOS 12 seriously improved battery life and performance on my iPhone X back in the day. It also made my original SE basically useful again after iOS 11 (iPhone X release OS) crippled them both.

Remember the MacRumors article that claimed iOS 26 and Liquid Glass don’t consume more power because using Instagram and Safari barely used new technologies, animations or Liquid Glass?
I was really hoping after all the constructive criticisms that they’d rework their „findings“ or redo their experiment.
Meanwhile many people actually multitasking, working with their control center/shortcuts and playing around with Liquid Glass elements knew there was a noticeable shift in performance and power consumption.

May I ask why you use Reddit in Safari? Does the webpage suffer from fewer bugs and doesn’t refresh just because you went and adjusted the brightness in control center…?
Herr Podspro

It’s not a flattering compliment to compare a somewhat recent Pro‘s battery life to Apples first mini iPhone, but it’s telling.
Do you use the always on feature?

Wish the same was true here.
The screenshot doesn’t even paint a full picture because for most of the time off the charger I didn’t even use it.
That was yesterday. However today I’ve been using my phone for an hour already in Safari here on MR and it reports a 4 percent drain from 80 to 76. Strange.
