Just curiosity here, but since I downgraded from ios 8.3 because of the problem with ifunbox etc (read here: https://www.macrumors.com/2015/04/13/ios-8-3-ifunbox-itools-sandbox-app-access ) I've noticed an amazing increment in battery life.
Keep in mind I skipped 8.2 at first, I was on 8. something and I jumper on 8.3 directly, so I didn't have data to compare 8.2.

Anyway, it's so noticeble I've started taking screenshots of this (it's an iphone 5c 32gb): this are 3 different days, I'm not a super heavy user, but I never experienced something like this.

Everyone has a different experience it seems. Some say some other versions gave them better battery life, while others don't really see much of a difference one way or another with most updates (at least within a single major iOS version).

For me 8.3 is by far the most stable and best version of iOS8 to date, but it also has the worst battery life.
I regularly got 11.5 - 12 hours usage from 8.0 - 8.1.1
I got 10.5 - 11 hours from 8.1.2 - 8.2
I now get 9.5 - 10 hours from 8.3
 
8.2 was great for me for battery life but 8.3 was even better. almost an hour of extra usage time on average.
 
Battery is about the same for me. 8.3 might be slightly better but not enough for a wow factor. I can get about 10-12 hours usage on 8.3. 8.2 was a little less, maybe 10-11 hours.
 
The best I've had so far was on 8.4 beta 1. Seemed to decrease a lot less when actually using the phone.
 
I'm on iOS 8.3 on both my iPad 2 (got it in 2011) and iPhone 5S, and surprisingly battery life is great. I used iOS 8.2 when it first came out and it really drained the iphone battery compared to 8.1.3, but 8.3 seems to have really improved it for me
 
A lot of the time it isn't the version of iOS that is less of a battery drain, it's to do with the installation process. If you do a clean install every time then you can get a better picture than if you do an OTA one time and then a clean install the next etc.
