Low Power Mode Is Getting Better in iOS 27, and It's About Time

iOS 27 is loaded with the kind of headline features that get all the attention, but the change I keep coming back to is a quieter one. Apple has put real effort into performance this year, and one of the things that benefits is Low Power Mode.

If you're someone who lives in Low Power Mode by the late afternoon, like I sometimes do, this is the upgrade that'll actually show up in your day.

The performance story behind iOS 27

Alongside all the new stuff, Apple spent extra time this cycle on bug fixes and speed. During the WWDC keynote, the company called out some specific numbers: up to 30% faster app launches, up to 70% faster loading of new captures in Photos, and up to 80% faster AirDrop transfers.

Those are systemwide gains, and Low Power Mode rides along with them. On Apple's giant slide listing hundreds of iOS 27 changes, two of them were Low Power Mode specific: faster Camera launch while in the mode, and the Camera using less power while in it.

The part Apple didn't really advertise

Here's the thing, though. The improvement seems to go further than those two bullet points suggest. Developer Benjamin Mayo noted on X that iOS 27 fixes whatever odd behavior Low Power Mode had in iOS 26, where the frame rate would drop but the phone could feel stuck. In iOS 27, the frame rate still lowers, but the phone stays genuinely usable.

That matches my own experience. Low Power Mode just feels faster in iOS 27 than it did before. It's the difference between a mode you tolerate and one you can actually keep working in.

A fair caveat on older iPhones

It's worth noting this isn't uniform across every device. Looking at what people are reporting, the speed gains seem to depend heavily on which iPhone you're using. Some folks on older models say Low Power Mode is still pretty laggy, while newer phones see the bigger benefit.

That's a little disappointing if you're holding onto an older iPhone, but it's also not the final word. We're only one beta into iOS 27, and performance almost always keeps improving across the beta cycle.

Bottom line

I'm cautiously optimistic here. Low Power Mode has long been a compromise, you trade smoothness for battery, and in iOS 27 that compromise feels smaller. If the trend holds through the betas, this could quietly be one of the most useful changes of the release, even if it never makes a keynote highlight reel.
