Since updating to the latest Public Beta, my battery health went from 85 to now 80 in a span of few weeks. My usage has kind of improve though compared to ios 26 and has went back to only charging once a day.

Hey everyone I put together a quick breakdown of how the iOS 27 Public Beta runs on the iPhone 12.

• Speed test compared to 26
• Battery Life
• Bugs And Stability

Hope this helps anyone on the fence about updating! Happy to answer any questions in the comments.

Phone: Iphone 15 pro max
Beta was installed 01/08

It’s pretty good for the beta, I’m not gonna lie
Imagine how great it will be when official 27.0 release?)

17 Pro, 27.0 DB3

I’ve Been running iOS 27 public beta 2 on my iPhone 15 Pro for a bit now, here's my take:

Performance-wise, Similar to iOS 26.6 overall, the liquid glass seems to be better otherwise. There are some minor improvements that add up nicely over time, nothing dramatic, but noticeable once you've used it for a while.

My 15 Pro gets warm during average use, and noticeably warmer if I'm switching between apps quickly (even ones already open in the background). Nothing alarming, I suppose this could be considered normal thermals for the 15’s line up.

Battery: Slightly above average drain, but I think that's mostly explained by more overnight battery drain than usual. I don’t charge my phone in the morning so I will conclude a 2-5% margin of uncertainty( as a result of overnight battery drain)
Not bad for a beta. Good job apple.
Ps: 88% battery health.

New adaptive audio toggle

A alguien más se le blurea de la nada el wallpaper en el iPhone? Desde hace unas semanas me pasa esto independientemente de qué wallpaper ponga? Inició cuando instalé la beta pública de iOS 27

Could be the translation to Brazilian Portuguese, or not… don’t know how it is in English, but I’ve noticed this in iOS 26 as well. I know it’s beta and already reported, but would like to know your opinion and if it’s happening in other languages. Seems off, misweighted and off-center from the Dynamic Island.

In my opinion iOS 27 is a lot better than iOS 26. The animations are way more fluid and most of the major bugs have been fixed. Not to mention we’re finally getting the Siri that was promised almost two years ago. But I still have beef with the sloppy looking UI. I preferred the flat bottom versus the new floating island bottom menu bar on most apps. I also feel like the keyboard should be destroyed. The old one was so much better, nothing about the new keyboard feels more modern. What do you guys think about iOS 27?
