How is it possible that 2% of the battery was drained, even though I had the IPP 9.7 (256 GB, wi-fi+cel) in airplane mode?

Is this something new? I thought my IP 4 remained at 100% when not in use, for days. Do I need to do something specific with the Pro 9.7?

Also, the battery app says there is nothing wrong with the battery's health, it's brand new.

P.S. Before I turned the IPP off (closing the Smart Cover), I had it charged to 100%.

Even though the iPad was turned off the battery will continue to drain. Closing the smart cover does not truly turn off the iPad completely. Really only puts it in sleep mode. When I first got my iPad Pro I thought the battery was draining quicker as well, but I restored it from my iPad Air 2 and it was still restoring the data. Once that was completed the battery drain slowed considerably. To turn the iPad completely off, you need to press the power and home button at the same time until the slide to lock comes up. Slide and then the iPad is completely shut down. However, when you turn it back on you'll have to wait with Apple Logo screen for it to reboot.

Is this true for any iPAD, using any iOS version? I always thought that in sleep mode, as you explain, after days it would still show 100%.

Perhaps that explains why the Battery app I have here says:

Standby: 30 days
Video: 10 hours

To a new IPP 9.7, 100% charged. Does that mean that if I let it in Sleep Mode, it would take 30 days to waste 100% of the battery?

If your iPad is rand new and if you restored it from a backup, you may be experiencing a higher than usual battery drain the first few days. This is from the iPad still downloading the backup file and/or downloading iCloud data such as documents and photos and such. I experienced this every time I updated an iPad and this is what Apple Support said could be the problem. After a few days the increased battery drain stopped.

I'm sure the battery drain will also be linked to apps running in the background via background app refresh. Depending on the apps running there, you might see an impact on battery life.

What I think is odd is that even if you turn the iPAD off, by doing the following:

- Begin by locating the iPad's on/off/sleep button. This button is on the top right-hand corner of most iPad models
- Press the hold button for a few seconds, until a slider appears at the top of the screen that says Slide to power off.

And before that, reducing screen brightness to 0%, airplane mode on, the rest of apps closed, etc. the battery still drains a little after a few days/week(s).

My iPAD 4, bought in 2013, had a 29/30% battery degradation, according to this app:
https://itunes.apple.com/br/app/battery-life-check-internal/id1080930585?mt=8

When I turned it on again after a week, the battery % was reduced from a full/100% charge to 93. I had the idea to drain the battery to 0% and charging to 50% (since I am selling this thing and will need to store for a long time without using again), and then I noticed the iPAD's temperature changed from 35ºC/95ºF to 40ºC/104ºF once I increased the screen brightness to 100%.

I have no idea if it was 30% before that, all I know is that now is 35% and even with all settings turned off or reduced, it remains that way. Now that is charged to 50%, I have turned it off again. It is said that the rise of temperature can be detrimental to the health of the iPAD battery, I just hope this didn't happen even more only because of this change in the brightness I did.

At least here where I live, not only the battery can't be replaced (and from what I heard, Apple doesn't do that, perhaps it's not worth the hassle for them), and after more than 1 year since the purchase date, the only alternative is to buy a new iPAD.

As for the IPP 9.7, it seems that after a few days, even with airplane mode on, you lose 2, 3%, then again in this case I didn't turn it off.

I have found that the ipad smart cover keyboard drains my battery on my ipad pro. I had stored it with a full charge for a week and a half, came back and it was down to 3 percent charge. Figured it was a fluke, charged it, left it for a while again and the charge dropped rapidly with no use. Finally stored it with the cover disconnected and removed and found it only dropped about two percent over the course of a week. Big difference, no longer store it with cover attached. Battery has been fine ever since.

From my experience being in a poor cell signal area I find if I leave the mobile signal turned on it will drain my battery as it constantly tries to find a mobile signal. Could this be applicable to you?
