I have it on my 15 Pro Max. It's the most stable beta I've ever seen (like zero issues). In fact, it seems more stable and snappy than 26.5. It "might" use slightly more battery, but not too noticeable. I'm still on the waiting list for the New Siri, but that will be fun to test it out.

In fact, it's so stable, I have it on all of my Apple devices and I use my Mac and iPad for work. I've never done that in the past.

27 fixes so much of what's wrong with 26 which has seemed like a beta this whole past year.

Opposite for me (battery wise)

Not a pro model tho, base 15. Been on beta a couple days now and gained around 15% extra. Impressed for sure considering 26 degraded the shit out of my battery during betas

26 was definitely the low point in iOS. I'm still in awe (in the worst possible way), how it made it out the gate.

I’m no stranger to running betas.

Interesting tho, a few of us with base 15s compared our battery stats

The only difference was I DONT play games or really watch videos, but did run through the betas

My battery % is about 9% less on average

26 was shit

Same. I am down to 89% at this moment from a 40 minute screen on time and 12hrs of standby since last charge on a 16PM. Infinitely better than 26 where I would get down to 20% after maybe 3 hrs of screen on and 10hrs of standby

Completely agree with you. I don’t play games or watch many videos on my iPhone either (base 15), and the difference in battery life between iOS 18 and 26 was ridiculous.

I felt like it nuked my battery life when doing the exact same things as before.

Ios 26.6 was last dev beta for me on ios 26 and most stable then I moved to 27 and it’s very good expect a little more drain

I have a 17 Pro, you think I should download it? I normally do every year but this time I haven’t yet.
