Battery Loss Overnight

New iPad same as my iPad 2
2% loss overnight
Every night I unplug my iPad to plug in my iPhone
I then use iPad next AM and it is consistently at 98% just like my iPad 2

Do you have all App Notifications off? Those would consume some battery because it has to poll for them.
Or is it sitting in a spot (a drawer perhaps) where it would have trouble finding a WiFi signal and maybe it keeps searching for one?

Not all App Notifications are off, but most. It is sitting in a drawer, but the wifi is always connected so thats not an issue.
Why is that an issue? If the OP is losing 10% battery life overnight while doing nothing, how about when he's using it during the day? (op already answered that in post #20.)
OP, I'd return it. That I not normal.
I think I'm going to after hearing what the regular battery loss overnight is. Thanks for your help, and everyone else's.
My new iPad loses from 0-2% at night, which is about 7-8 hours long usually. I do have a smart cover on it. 10% seems a bit excessive.
Push notifications only drain battery when one is received? Also does location being on only drain when it is being used? Doesn't the iPad only use I cloud when it is plugged in?
I lost about 10% overnight..
Connected to Wifi in my house, Verizon LTE enabled, Bluetooth turned on (but not paired to anything).
A lot faster drain sitting idle than the ipad2 for sure.. if this isn't normal, I better exchange it :/
Maybe only Wifi-only models don't lose hardly anything overnight.. I'm going to turn off Verizon data overnight tonight and see what happens.

Took mine off the charger at 6am yesterday. I didn't use it at all yesterday. When I used it this morning it was still at 100%. After using it for about 10 minutes it dropped to 99%. Not too bad.
EDIT:
Wifi and cellular data off until I used it this morning.

I look at my percentage at night before I close the smart cover and if it does not need charging, I just close the cover that puts it to sleep. The next day the percentage has not dropped any, not a single percent.
If yours is losing 10%, it is doing something. Are you sure you are closiong all your apps. The social networking apps wopuld be my very first bet!
If not you have a defective unit.

Should let us know if yours is wifi-only or 4g equipped (with a data plan) and what's turned on, whats turned off, etc.
Folks,
All these anecdotal comparisons of how much battery is drained under various scenarios are pretty much useless.
If you check the instructions for battery management for the iPad you'll see that Apple recommends turning off the iPad and charging completely from the 15% remaining point to 100% about once a month.
This operation corrects the mis-calibration of the battery monitoring on the iPad. Unless that is done regularly the battery monitor will become increasingly inaccurate and will result in readings that suggest a rapid battery drain from point a to point b and a much slower drain from point c to point d with the iPad doing exactly the same things.
This is the nature of lithium ion batteries and the battery monitoring software/firmware in the device and it's not unique to the iPad. (Exactly the same issues arise, for example, with phones and other tablets that use lithium ion batteries.)
It's possible, of course, that the OP has a faulty battery. But it's MUCH more likely that his battery monitoring software is simply mis-calibrated because the use profile for various voltages is inaccurate.
For those interested in pursuing this topic, take a look at the website below and the particular article cited.

My iPad 1 hasn't been turned off in two years (never), and still got the same battery life and standby since day one.
Adding to the thread with my experience (anecdotal of course) I have seen a range of battery loss overnight.
For my first week with my new iPad I would see 7 to 9% loss overnight without any apps running but lately the loss is reduced and in fact most recently I turned on in the morning after six or seven hours and it was holding a great charge with 99% remaining.
I suspect this improvement is due to the battery being conditions and calibrated more accurately. I have read in a few threads about the iPad battery not holding a full charge nor reflecting as accurate or reading as possible Intel it's gone through 5 to 10 full discharge/full recharge cycles. In addition to our improvement in holding a charge overnight I have also noticed a generally better battery life.
I am far from a hardware engineer so my observations are purely that of an average user – but I would definitely say I noticed improvement after I've gone through a full view charge and discharge cycles.
So I might recommend to the original poster or anyone else with similar issues that they be a little patient. I was certainly anxious when I first got my iPad and saw a much larger loss of battery overnight then I did with my iPad too but after a few of the full charge/discharge cycles I seem to notice a marked improvement.

I know there's some calibration issues going on... Yesterday I rebooted my iPad at 98%.. upon reboot, it showed 100% again..
