This is something I noticed right away with my iPad 4 when I upgraded it to iOS 8 (from 7.1.2) when it first came out and I immediately downgraded! It wasn't all the time but it was noticeable every time it happened when I would touch usually a third party app there would be a half second to full second pause before it would go into the transition animation whether it's the fade or the app spring animation depending on if you have reduce motion set. It still does it on my iPhone 6 with 8.4 once and awhile but I can never get it to happen on my iPad 4 with 7.1.2. It's always smooth. I went ahead and played with beta 3 on my i6 too and noticed the lag was even worse like 1-2 seconds like you guys are saying! Hopefully they clean this up! I've been using iOS since 4.0 and things were always very smooth and no hesitation until iOS 8 in my experience!
Got a tip for us?

Yes... I filed a bug report about this and engineering has been asking for further information.
Did you update from other version (9B3, 8.4.1B or 8.4) or have you done a clean install?
Re: Apps taking 1-2 seconds to open after tapping.
If you leave them open in the app switcher, this doesn't seem to happen. Only happens when opening the apps for the first time, so there is a pretty simple work around if it's annoying people that much.
Scrolling did seem slightly laggy at first but it's okay now, everything feels pretty responsive though still not 8.4 standards, obviously.
Battery life? Jury is still out

Hope it's the indexing that's hitting my battery just before I wrote this I watched my battery level on my iPhone 6 go down by roughly 1% per minute. Gave me horrific memories of beta 1, hope this levels out over the next day or 2, also don't understand why my iPhone 6 takes such a hit with indexing when my iPad Air 2 is coping just fine
Agree, the only thing I think I notice is that the multi-touch gestures, especially the four-finger app minimize gesture, seems less responsive.
I've reported a bug to Apple (no: 21939123). Since my OTA upgrade to 9.0b4, phone runs very hot and battery life is terrible. This happened to me on b3 too, but I resolved it by reinstalling via iTunes, and not restoring from backup (which just brought the problem back). I'm not inclined to go through that again unless I can help it. I can fix the problem by logging out of iCloud on the device, but that's a non-starter for me.
(Technical details: the CommCenter process has incredibly high CPU usage, ~100%, permanently. If I sign out of iCloud, it drops to normal levels, i.e. 2-3%. Turning individual parts of iCloud off does nothing to remediate the problem, only signing out completely. I'm using the same iCloud account on an iPad Air, with 9.0b4, and see none of the same problems.)

My iPhone's have always done that after fully charging to 100%. A lot of times it won't drop below 100% till I hit about 30-45 mintues of usage so it takes some time to get the ball rolling on their algorithm. They want to show you the highest possible percentage to make you think you are getting better battery life at the beginning. You'll notice battery seems to drop faster after about 50% or so too as the number becomes more accurate. This is my experience since the iPhone 4 with all my idevices. Try leaving it at any percentage under 90% or so and you'll see it will drop 2-7% overnight. Have a great day!
In most cases of troll like behavior on the Internet, exaggeration is a commonly used method of stating what is obvious in the completely opposite sense so as to evoke humor. In other words.....
Could be a combination of your phone indexing itself a bit like spotlight on a Mac will run the cpu while is sorts out its file directory, I also suspect that after installing the phone's sending a lot of data back to Apple to analyse. Give it a day or 2 and see how it's going. each beta except beta 1 has caused this behaviour on my iPhone 6 then the phone settles down after a day or 2 and you can then get a good idea of how long battery life will last.
Edit: also check the battery section in the settings app, I found a bowling app last night that was running a hell of a lot of the battery probably an incompatibility with iOS 9 also deleted Facebook since beta 1 as that seemed to run a lot of the battery down.
I can't really comment yet on battery since I've only been using beta 4 for about 1\2 day but I can tell that cell reception has improved with beta 4 vs public beta 1. They must have done something cause reception is better on Verizon than it was on public beta as I can tell my battery is not draining as fast.
B4 battery is bad. Not B1 bad but second worst so far. B2 was the best battery life I have ever had.
Not sure what's causing the drain in B4 but at 100%, it drops to 60% within an hour and that's using Spotify, a hookup app and email with some texting. Nothing crazy.

It's the CommCenter process, which I'm sure isn't indexing anything, and it stops immediately when I sign out of iCloud. There's no rogue app either. I'm using Instruments to watch the CPU activity live, so I can see the consequences of changing settings and so on immediately. This happened on b3, and persisted for nearly a week, until I did a clean install.
