iOS 26 battery life thread.

Did you happen to have adaptive power turned on? It’s usually on by default on iPhone 17 models. Regardless if you are using an iPhone 15, 16, or 17 Pro, we’ve found adaptive power to be a bit of a gimmick and not very helpful. It mainly just dims the screen and reduces the refresh rate, which doesn’t really make a difference. Even the Apple Genius agreed with me when I asked about it!

I have it turned off. Sometimes I turn it on for like 2 weeks but I've never seen any difference in battery life with it turned on or off so it's mostly turned off.

They definitely had to do something with battery life since nothing seems to help me, no hard resets, no app updates, it's still pretty bad compared to 26.3

Also I have already posted that in this thread but there's a YouTuber that keeps comparing battery life with different phones and on different system versions and he compared iOS 26.0.1 to 26.4 on iPhone 17 PRo Max and on newest iOS version, he's phone got less battery life.

12h 13min on iOS 26.0.1 and 9h 41min on iOS 26.4 is quite a big difference.
And i personally have noticed worse battery life on 26.4 and even worse on 26.5

Maybe that explains some random changes to performance I witness at times, but not had the notification saying low power mode is active on my Air yet. I’ve turned it off now.

For me, I always get the notification when it’s on, and low power mode only kicks in when the battery is really low.

However, I’m not sure if this is the case for everyone, but from what I’ve seen in this thread, even users with the same iPhone as me have mentioned that it’s not worth using. It doesn’t seem to fix anything and doesn’t make it worse.

It even affects the refresh rate, which is the most frustrating thing about it, even though I’m not using low power mode. doesn’t make sense.

Turning it off brings back the normal iPhone experience vs being locked in with all of AI junkyard mode on your battery settings !

Btw here’s a reel to watch bout the power draw of iPhone 17 vs iOS 26:
