iPad Pro Standby Overnight Drains 1%/Hr the Battery

[brosenz]

I have the 128GB + LTE version with T-Mobile and very good signal. If I leave it overnight (around 8 hours) idle with no applications running just after a reset (Power + Home until it will reboot) it will drain an average of 1% per hour, here are some measurements:

- 11/28/2015: 10PM (70%) ---> 6AM (61%)
- 11/30/2015: 10PM (47%) ---> 6AM (37%)
- 12/01/2015: 10AM (72%) ---> 6PM (65%)

Normally on my other iDevices (iPhone, iPad) the overnight discharge will be around 1-3% but never 10%, it seems to much to me, the device will not last more than 3-4 days, and Apple usually advertises up to 30 days standby on iOS devices.

Things I have done proactively to optimize battery usage:

- During the night "Do Not Disturb" is active
- Optimize location usage
- Optimize background app usage
- Disable Fetch in Mail
- The iPad Pro was configured fresh, NO restore from backup
- I have almost the same apps on the iPhone 6S Plus and no drain overnight
- Usually I will wait until the battery is 5-10% before a full recharge
- Contacted AppleCare over the phone and the iOS diagnostic was fine

I have an appointment tomorrow at the Genius Bar, but I really do not know what else they can do? any suggestion? what discharge % are you getting on your iPad Pro's? thank you

Hmm, mine doesn't really even seem to die, but I only have a wifi model... right now mine is at 8 hours of use and close to 80 hours of standby since last charge and still got about 65% battery left lol

That sucks :/ I have been getting very little drain overnight on mine. About 3-4% in 6-7 hours. I've been hammering away since 8 am on my pretty constantly and I'm still at 68%.

I didn't notice this thread, but yeah, I just posted same:

Mine is basically draining at or above 1% an hour. It's a little disconcerting.

Mine's charging overnight, as I use it every day. No chance to check.

Usually charge overnight, but lost 3% the night I didn't. Not enough to help you though, sorry.

Have you tried turning airplane mode on? After the screen the next biggest drain on the battery is the cellular array. Even if your not signed up to a plan the iPad will be searching for towers.

My advice is airplane mode on then turn wifi and Bluetooth back on.

Mine went 18 hours today without use. Just turned it on and it is holding at 100%. Just answered the same in another thread but no use, no drain today. I'll play as long as possible this evening but getting tired
I'll do a more thorough test this weekend but I've had it three weeks and while usually charging overnight, there's been times I've forgotten to charge and with decently heavy usage I've easily made it through two days of everything I need it for and another 34% left after 48 hours
