PowerBook, Mac OS X (10.6.2)
My iPad battery drained from 67% to zero in 8 hours. No apps open in background.
Has anyone had similar?
Yes, I have a similar problem. My battery drains quickly whether I'm using it or not. the only way to keep it from draining is to power it off. If I kept it in sleep mode and didn't use it at all, my guess is it would drain completely in less than 3 days, maybe 2. Certainly not 30.
I went to the Genius bar yesterday because I was having a similar problem. Here's what they told me, which I've discovered is true after trying it:
When you put your iPad in "sleep" mode, it really isn't sleeping. It simply turns off the screen. Every app that is open will continue to run in the background. This is the flaw with Apple's multitasking.
To get maximum battery life, you need to quit apps before putting your iPad to sleep. To do this, double-click the Home button, which brings up all open apps at the bottom of the screen. Press and hold one of these open app icons, then press the Delete button that pops up (a dash within a red circle). Do this for each open app. You may be surprised how many open apps you have! At the Genius bar, they did a test on my iPad and it stated that I was low on application memory, and this was the reason why.
To further reduce your battery drainage, turn off WiFi, turn off Cellular Data, turn off Notifications, turn off Location Services, and reduce the brightness of your screen.
I wish in the next IOS update Apple would have a way to close all apps at once!
My battery will sometimes last a massive 8 hours when in idle mode and with no apps open.
Other times I can't turn it on and it's still on same % as when imleft it.
Very random and a bit crap really.
