Well, it's not useless it can still give a comfortable idea. Doing it at a low percentage gives a bigger and more complete overall picture, but various other intervals can be of use as well.
It gives an idea of how it's draining and where it is at a certain percentage. Definitely not useless.

It's not useless. I personally don't let my phone go down to 1% every time before I charge it...I usually let it go to about 20-30%.
You sound dumb for saying what people are experiencing on THEIR device.
Yup. The only way to see the true time of a full charge and discharge is to charge the phone overnight then use it till it completely shuts itself off then check the low battery log in the diagnostics. If the battery meter calibration is off sometimes the phone can stay on 1% for 5 minutes up to an hour. That's been my experience with my iPhone's anyway. But I agree it's more accurate at a lower percentage because the meter for me has always seemed to speed up and catch up to its more accurate reading below 50%.
Another thing I should add is actually even after the phone shuts itself off due to low battery it isn't actually always completely totally dead every time. It shuts the iPhone down at a specific voltage. So say your battery is at like 5% and you crank the brightness to the max and start playing asphalt 8 or something similar you could get the phone to shut down because the voltage drops below the threshold . Give it about 5-15 minutes and the phone will come back on with about 3-5%! I've done this a few times to know it to be true. To be sure the battery is as dead as it will get you need to be doing something with the phone that isn't very power demanding and let it shut off and then it shouldn't be able to turn back on at all. Another little thing is that there is always going to be just a little bit of power to be able to turn of the screen to show the little battery and plug in screen. If you discharge a lithium ion battery totally all the way it will ruin it.

Mine isn't "better", nor did I ever claim as much, but it's definitely on par with 8.4.
Plus I think it's safe to say that people here know their own devices, their typical performance level, and how long their batteries usually last. So nah, it's not dumb at all.
Holy smokes, its a beta release...
One thing I have noticed is a few apps are locking and not releasing resources which contributes significantly to battery drain. The latest beta is working quite well, other than the power drain, which for me has been easily fixed by closing apps that I have been using.
When I don't have apps locking resources (probably because they arent written for iOS 9 yet) battery life is very good. Very happy that the latest release fixed a lot of the stuttering (yay optimizing graphics engine) and search is back and working well. I missed having search in the previous release.
My ip 6 is working just fine now. The apps that wouldn't open in public beta 2 do just fine now in beta 3. My phone feels like its on a non beta version of the os. I'm happy with the way progress is being made. It's funny the way people here complain about battery usage. If you sitting and stare at your phone of course you will see the battery percentage go down. The best way to fix that besides going back to 8.4 is to restore as a new phone for the nuclear option or just reset all settings on the phone. Some device are going to handle the updates differently than others. If you can't handle it don't test beta software. Oh, and don't go to a website forum and complain. Use the feedback app and complain to the guys that actually built this version.
But you can say that in the first 50% you got that much usage which then can be compared to first 50% that you get on other charges or perhaps of some use to others to compare their first 50%. Comparisons can be made on usage that isn't 100% or 90% or anything like that. It's not just all or nothing.
But everyone knows how they use their devices and what to expect from it at X percentage.
Beta 5 works ok on iPad Air with a clean install. The difference in performance and smotheness is not as visible as on iphone 5 lets say, but the potential to be faster than 7.1.2 is there, which is good.
Kind of dissaponting that apple didn't continue to make ios9 more responsive in some areas. For instance in this scenario: when you have 4 or more apps in app switcher, close an app and tap on the homescreen rightaway nothing happens, you have to tap the second time to get there.
If you do the same thing with only one app open the responsiveness is tremendous and miles better than any iOS up-to-date.
Hopefully apple will carry this speed all the way across the OS.
It seems like apple gave up on an interruptible screen unlocking animation (like in iOS6) a long time ago, where you could swipe the home screen before the animation has fisnished. Thats when iOS7 felt instantly "dull" in comparison, let alone iOS8.
Its a very small thing, but the one that makes your device instantly more responsive. They have it on iPad as "pinch to homescreen" gesture, but never carried it over to homescreen for whatever reason.
Anyways, after a year on half assed iOS8, iOS 9 in general looks very promising.

I've used my iPad Air 2 and iPhone 5S for a couple of days now
- iPad Air 2, about the same performance as the previous Developer Beta, nothing to report on the battery front that is different from the last beta, it performs exceptionally well, they've fixed the app launch delay too. Battery life on average around 12-14 hours on a full charge.
- iPhone 5S, considerably worse than the previous beta, takes literally a few seconds for the screen to come on, app loading is considerably slower, battery life is abysmal, I don't quite know how they've managed to make it so crap in comparison to the previous beta (Which was excellent on the 5S) ~5-8 hours.
My battery 3 or 4 times since yesterday has dropped 10% at once. Goes from 68 to 58 or 72 to 62 all at once. I've never ever seen a beta this bad. And I've used betas since iOS 7. This is just ridiculous. I know it's a beta but holy cow. I'm on 5s. Don't know if I can stay in this beta. I'm getting 3-4 hours with minimal use on fully charged battery. Beta 4 was much better and beta 3 was even better.
Battery life has been amazing so far on my end. This almost feels like a GM build to me. I see a lot of people are having issues, so I'm quite thankful my experience hasn't been troubled. The only thing I can think of is that I have Background App Refresh turned off on everything except Weather, Withings (scale), 1Password, and DarkSky. But then I have 254 apps installed and fear turning it on globally would turn my battery into mush.

So if apps open a tiny bit slower (a second or two essentially) that's enough to say it's not ready to be used on a daily basis? I would expect something more substantial than just that.
DP5 feels a little faster than DP4, but there is definitely something running in the background that is keeping my 5s very warm and killing the battery.
Third-party keyboard support still hasn’t gotten any better, though Apple does seem to be making SOME changes since a blank placeholder comes up now instead of nothing at all.
