How fast does your iPad battery drain while sleeping with Wifi on?

overnight, when i go to bed, I leave the WiFi option turned on and when I wake up the battery seems to drain around 10-20%. Is that normal? could it be because I have push turned on for my contacts and calendar?
 
Even your wifi is turned on, when sleep mode you will not receive a push email. So your battery will remain intact. This will apply on ipad that is not charging.

Your battery should remain 100% on sleep mode overnight. Without charging.

Just a data point.


I charged mine last night to 100% before I went to bed, then unplugged it.
WiFi on, one push email account (MobileMe), & one email account it fetches once an hour.

Battery indicator 6 hrs later: 100%.
 
My data point is similar to mullman's. But I have a similar problem to the OP's if I turn on my corporate VPN.
 
hmm... maybe i should do a reset and test my iPad again... something don't seem right.

Not true.
I hear mine beep through the night receiving email.

I have found that the battery indicator "hangs" on 100% longer than any other number, meaning that the 100% charge figure appears to be a bit rigged.

In terms of the OP's original question, my pad usually drops around 5% overnight with push turned off.
 
My battery definitely discharges faster with push on. I turned it off and did fetch manually for email and my battery stayed at 100%. With push on and push email it drops about 10% and during the day I notice it drops quickly, getting between 6 and 7 hours of battery life rather than the wonderful battery life people write about. I do get a lot of email though and I think that is what causes the big drain so no push email for me, fetch instead.

push will definitely drain your battery faster. i don't use push on my iPad or iPhone anymore. It makes a huge difference.
 
I keep Push on.

Maybe 1-2% while sleep.

And I get about 8-12 hours of solid usage depending on what I'm doing.
 
I get new mail sounds for my GMail account (activesync) at the same time my phone gets it (within 1-2 seconds) when the screen is off and locked.

So it certainly appears to be pushing just fine.

I get less than 1% battery loss at night with mobileMe and GMail(activesync).
 
Bumping, even with push off - it appears to still drain a good 5-8% overnight (8 hours-ish), is this the norm? Note that there are no other notification apps.
 
I could have both WIFI and 3G turned on, exchange push on, IM push on, and there is hardly any difference at all in the morning. I am sure it is using something, but not long enough for it to make a noticeable difference on my device.
 
My iPad drained away my battery while it was off about 30% (10 hours)

I turn off all notifications. fetch mail set at 15 minutes, Wifi off too.

anyone knows what is wrong?

Emails ARE pushed to the device regardless if it asleep or awake...unless u have PUSH set to FETCH in Settings.

It is normal for the battery to reduce slightly overnight. Perhaps 5-8% is normal. Depends how long you sleep really doesn't it.
 
When my iPad was new it would drop 0-1% overnight. Now that I have had it for a couple of months it drops 5-6%. The only difference is that I have we rule sending push notifications but I am not sure how many I get as when I wake up in the morning I only see one no matter how many were sent.
