iOS 27 Will Reportedly Give Your iPhone 'Longer Battery Life'

by

iOS 27 Will Give Your iPhone Longer Battery Life FeatureiOS 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.

iOS 26 also promised to give longer battery life, and oh boy, we sure didn't get that

I hope they're right. We could do with a serious de-crufting of software. Standardizing OS's on Apple Silicon across the range seems like an opportunity to do it.

But will it be a net gain over iOS 18?

Yeah, sure. We also heard that with iOS 26 and it's "adaptive power mode" and how did it end?
My journey of using my 16e bought in march 25:

iOS 18 on it. Wow this is so fast with incredible battery life. And soon I’ll get all of the Siri stuff promised at WWDC 24 - can’t wait!

Ok new Siri stuff then. I’m not going to believe Apple’s marketing again for a long time.

But wow is this phone fast and I just love the battery life.

Suckered in by 26 and Liquid Glass new shiny. I guess I should wait though?

Ah 26.0 is out. Who am I kidding?

Ok .0 is always rough. I’m sure they’ll improve it.

Ah I can’t downgrade to 18 now. But I’m sure Apple will improve it.

I’ll turn adaptive power mode on. That will help. Right? But my battery life is still awful. Maybe that toggle doesn’t actually do anything.

Ok I’m glad that they’ve made a tinted mode as I’m growing to dislike the Liquid Glass transparency. I can’t read text on it half the time. Is there really no way to go back to 18?

Why has my battery life taken a huge hit? My 16e isn’t a year old even. I’ve lost about 20% capacity seemingly and that battery meter goes down like sand in an hour glass.

Wow low power mode is unusable. You can see how much processing resources it takes to render all these translucencies even in tinted mode.

I really regret updating from 18.

Let’s hope that 27 isn’t awful.
