Seems like everyone has different battery life depending on use habits. Beta 3 just eats my battery especially in low signal areas.
 
I play iPhone 6 Plus heavily. Until now, no obvious issue found. Everything works just like that.

I have iOS 8.4 beta 3. I didn't use iOS 8.3 too much, though.

Seems that this varies from phone to phone.
 
Mine seems a little worse. I was getting around 7.5 hours of usage out of a full charge and about a day on standby, and now it's down to just over 5 hours of usage.
 
I never charge my phone overnight. Usually it is fully charged at around 11 PM.

I always have it turned on 24/7 due to my profession.

What I've noticed since updating to 8.4 it that, even with no activity at all, I wake up at 6 AM with a 75% charged, so don't know what happened in the night that caused a 25% drain.

Before 8.4, I was able to wake up with 97%.

No changes have been made to the general settings.

I'll keep investigating this issue further, as it seems it randomly occurs.

I just have to ask the question:

If your phone is critical to your profession why are you installing beta software?

The phone I have installed 8.4 in is not my main phone, zone23.

I have two: the primary one also remains on 24/7 but still on OS 8.3.

I was just sharing my experience when I read what this thread was about.

Well I may have spoken too soon. Yesterday, after having 8.4 on my phone for the 4th day, I managed to squeeze out 7 hours of usage and 21 hours of standby out of a full charge. Not too bad. I'm thinking cell availability might be part of my issue.

It's been a problem since 8.3 for my iPhone 5S. Beta 3 isn't any different. iOS8.2GM was fantastic for battery life, going from 100% to 92% overnight.
