adaptive power mode

I know that on the iPhone 17 (which I just got) there's adaptive power mode. I read about this, and from my understanding, it'll sometimes slow things down in order to conserve battery. I'd imagine that when this occurs, VoiceOver can get pretty laggy, so I've turned it off.

I'm curious if anyone has it on, and what your experience is if and when it is ever in use. Do you notice a significant difference with battery or not really?

Loving the new phone so far, though! Very responsive with VoiceOver and I'm really enjoying the high quality sound.

I haven't noticed significant slowing with the feature turned on. I'm using an iPhone 15 Pro.

Same, using 15 pro make no difference to VoiceOver at all.

I know it causes certain things to take longer if activated. Not sure what these are. Making sure there hasn't been a noticeable delay in things like, say, messages or WhatsApp.

I think the performance reduction is mostly for heavier tasks, not for things like messaging. I've used adaptive power mode for a while now and honestly, I haven't noticed any slowdowns whatsoever.
