My iPhone Air seems to be getting hotter by the day this beta. I had to turn it off and leave it off until it cooled down because force-closing apps and restarting the device didn’t help the problem.
Got a tip for us?

I’m seeing the same. Heat was gone the first few days after updating. Now it heats up a few times a day doing normal stuff.

Heat has been crazy on mine too. I've pinned it down to something to do with location services in my case - though, pokemon Go seems fine

This is kind of a catch-all overview. Better than 26.x but …. 🙄
iPhone Air - overall not a bad beta. Definitely not the worst. It is good enough IMO for daily driver UNLESS you use Safari heavily and use apps like Docusign.
Biggest issues:
1. Car Play - Have had a couple of disconnects. YouTube Music will randomly stop working until I restart on device. Using on 2026 Chevy Colorado. The PU recently had a couple of major system updates so that may be part of the issue. Also, on device Google Maps is Dark but on the infotainment screen it is in light mode. Apple Maps shows the correct shading.
2. Safari. Tabs freezing, tab reloading, and video crashing. Been a pita.
3. Device randomly gets warm for no apparent reason. Example: watching TV and reach over to pick up the Air to loook up something. Device is warm. Odd.
4. Messages - spell check or suggested words will stop working. Area just goes blank. Close and open brings it back.
iPad Pro 11 M4 - Overall a pain. I predominantly use this as a consumption device.
1. Video crashes. YouTube, Prime, Peacock Plus, etc…. Be watching and it freezes. Then a few seconds later the app closes. On restart is has no idea where I was.
2. Safari is a mess. Same as the Air but happens more frequently.
3. I use my iPad with the Apple Magic Keyboard. At times the device just stops using or acknowledging the MKB. I have to undock and redock to get it to rediscover the MKB. This also occurs when I connect the Apple Pencil to the iPad for recharge.
Other items.
AirPod Pro 3 - will randomly switch from NC to Transparency. Have to go into BT to reset.
AirPod Pro 3 - will rest to 80% max charge each time after I charge the case and buds to 100%. Then it asks me if I want to charge to 100% - even if they are already > 80%.
Apple Pencil Pro - The pencil function can cause odd effects. App freeze, Music pause, Annotation sometimes just won’t work.
Siri is better mostly than before but still does some really dumb stuff.
Spell Check and Grammar Check still suck. In this post, it flagged predominately and suggested predominate. Then after changing it via the suggestion, it immediately suggested predominately. WTF?

I was comparing 26 release to 27 beta. I wasn't saying it's a fair comparison, I know very well 27 beta is not optimized. But people often want to know how much battery they "lose" if switching from release to beta, which is what I answered. It's totally expected to be that way, and I was giving that information.
I also have my iPhone 17 Pro Max randomly heat up with this beta. Usually when it starts doing that I need to restart as it will be getting worse and worse, and drain the battery.
I think it may have something to do with location services, but not sure what exactly, as not all apps do it.
Weird, I’ve had none of these problems on B4 apart from running a bit warmer and battery life not being great, which is normal for a beta as they are still logging. I did have a few of these issues on B3 such as the Apple Pencil Pro not working correctly but B4 fixed them. iPhone 16 Pro Max and iPad 11” M5 Pro (with Magic Keyboard).

My iPhone 17 got very warm one time with (seemingly) nothing running. I did a hard reboot and it hasn't happened again so far.
It's the only time I've had this issue in any of the previous 26 and 27 betas. It's quite impressive, really.

None whatsoever; iPhone Air
I'm curious, when reinstalling iOS fresh, are you restoring from backups?

My battery life absolutely tanked on Saturday.
Battery said it was Messages that was the culprit, but no amount of restarts would resolve it.

iPhone 16 Pro, has the same symptoms, let's see if beta 5 fixes all these bugs!!

Odd. Within the last week, I have paired five second generation AirTags to my 17 Pro Max running the latest developer beta with zero issues.
