I am currently at 49 percent with 4 hours and 12 minutes of usage and 4 hours and 34 minutes of standby. I have brightness at about 50%. Is this normal battery usage or is it draining too fast? I am on iOS 8.4 with an iPad Air 2.
iPad Air, iOS 8.4
Seems A-OK to me since the advertised battery life of the Air 2 is "up to 10 hours".

Also Google "battery life ipad air 2" for a wealth of additional info/data provided by other sources than Apple themselves.
Wouldn't this give me only 8 hours of battery life instead of the advertised 10 hours? Or is the "up to 10 hours" supposed to mean on some occasions will I get the 10 hour battery life?
It depends on what you're actually doing with the iPad. "Up to 10 hours" means just that. If you're playing 3D accelerated games that require alot of processing power, you can get much, much less than 10 hours, even down to 6 or so and likely even less. If you're just sitting idle at the Home Screen at 60% brightness or so, you may get 10. Different usage will result in different battery life. Just because you got 9 hours one day doing some specific things, it doesn't mean you get the same 9 hours another day doing different things.
I just left my iPad on standby to do something at 48%, but when I came back it was 45%. What could cause this?
Possibly due to processes running in the background. Check under Settings/General/Background App Refresh.
My suggestion to you is to not sweat the battery details (unless battery usage is way out of whack)...and enjoy your device.
Also see the following page:
I Already had background app refresh off though. Could it be location services?
Location Services could be another service that can use the battery. It's all outlined in the document I linked to above.
I think I've supplied all the info I can here. Good luck.
iPad Air 2 battery usage normal?
