iOS 8 Performance/Battery Life

My thoughts:
3G: good on iPhone OS 2. A little slow on iPhone OS 3. Apparently very slow on iOS 4.
3GS: apparently good on iPhone OS 3, 4, 5, and 6 (didn't have one, just from reading)
4: good on iOS 4 and 5. Slow on iOS 6 and 7 (probably because of the 4x resolution increase over 3GS)
4S: good on iOS 5, 6 and 7.
The 3GS/4S are significantly faster than the 3G/4, so I'd expect them to progress similarly (as did the 3G and 4). I think the 4S will get iOS 8 and run it acceptably well. The 5 and 5S should run iOS 8 with no problem at all.
For battery I don't think you'll see a decrease. The only significant drop I experienced was in iOS 7, probably because it was such a big change.

If you're happy with iOS 7, I say stick with it. I'm considering doing the same. Plus if I ever decide to jailbreak it again, I'll always have that option. I kept my dad's iPhone 4 on iOS 5 and I'm glad I did. My mom's 4 on iOS 6/7 is much, much slower. If I had kept my 5 on iOS 6 I'd be missing out on some nice graphics but I'd also have 3 hours more battery usage every charge...

Nobody can say with certainty until it's released. Apple wants to continue to improve the user experience. I'd say they aren't doing a very good job but that's off topic. 
A nice thing about iOS 8 is that it shows what application or process is using the battery so there will be less mystery around it. I hope it's accurate (meaning background apps are metered instead of their process showing up as Lock Screen).

If anyone is curious, performance of beta 3 on the 1st gen iPad mini seems more or less identical to the performance of it on 7.1.2.
good thing ya blocked out your carrier lol
Haha, I had the same thought. Your carrier identity is just so incredibly confidential!
I'm not optimistic about huge improvements in battery life. There haven't been any corresponding improvements in battery technology, at least none that I've heard.
Okay, just for my GF.
On my iPad Air, it's speed is clearly better...
However, for both iOS 8 and Yosemite, I'm getting much less battery life (about 1/2) than on stable software... :|
