Hi
Thought I'd ask before doing a fresh install. Has anyone else's phone (5s) been running hot using iOS 8 beta? Noticed it since the first beta, phone gets very very hot at times.
 
I didn't have any problem with the previous betas doing this until the 4th one. My iPhone 5S became very hot to the point where the screen would dim. I wasn't doing anything processor intensive either. Just simple iMessage or email. The device got really warm. I rolled back to 7.1.2 just because I didn't like that it was getting so hot the screen would dim. Felt like I was doing damage to it or something.

Other than that, the beta was very stable for me
 
Beta 4 is making my phone really hot with no reason, brightness not even at 50% and even on wifi just browsing the web.
 
I have reverted back to 7.1.2 for now and phone isn't getting so hot.
 
Current beta, yes it gets hot and battery lasts way less than before, previous beta's did it occasionally but it was usually fixed with a reboot, but not now on my iPhone 5
 
Mine was working just fine until last night. After a random restart, the CPU is now staying around 66% usage, even after closing all apps. I checked the battery usage and "Home & Lock Screen" is currently at 18% battery usage. I've restarted a few times, and it's still running warm and draining the battery. Not sure what happened or what to try next.
 
My iPhone 5 running iOS 8 beta 4 only seems to get super hot for me after a long period of usage and when my iPhone is searching for Cellular Service in a low signal area.
 
I just rolled back due to after a week on iOS 8 beta 4, the phone got extremely hot and then my wifi would not stay connected even after repeatedly doing network settings resets. After going back to iOS 7.1.2 phone is no longer hot and wifi is working fine.
 
Beta 1 ok, beta 2 hot, beta 3 ok, beta 4 hot... Wtf..?!
Just hope that tomorrow's beta 5 will fix this issue once and for all.
Btw; iPhone 5s here...
Doesn't happen on iPad air, but plenty of other issues instead...

Up until beta 4 my battery life was almost as good as 7.1.2 and then my phone (5S) started to get very hot when I wasn't even using it and the battery went down 2-3% every 2 minutes. I decided to downgrade to iOS 7 and hopefully beta 5 is released today so if it's stable enough I will go back to it.
