Out of curiousity if your iPad is still lasting 10 hours...I remember at first it would take forever for 100% to trickle down to 90%, but now it seems my iPad goes down from 35% to 9% in less than 2 hours...
Yes.... unless i use my iPod Charger (the original one i got for my ipod video) on it. I have no clue what it does, but I can't make it a day on it and it took a couple of days to cycle the battery up to snuff.
I'm back to charging every 2-3 days with the same use.
It didn't last long yesterday - but I discovered that the child had cranked the brightness up about all the way in the car while she was streaming BBC Radio 1 on Wunderradio
(on that note, but wayyyyy off topic, a lady at speech therapy asked me if i'd heard about the body they found behind a store yesterday, i told her no - my child has discovered BBC radio, i know nutin' local.... ask me about the UK! I can't totally blame the iPad 3G for this though - we were listening on XM too).
Originally mine was lasting forever, even after I JB'd it. But then I installed a whole bunch of crap and something was making it drain on standby like it was in use and be flat by the end of the day without using it. I unJB'd it but it is still not lasting as long as it used to.
I've had mine for maybe a month and the battery is certainly not as it was. I have wifi on and mostly use it for the Internet, screen brightness is about 25% and have none of the push notifications on including email.
Is there an app that logs the usage? Otherwise, I just unplugged it 30min ago at 100% and will keep an eye on it. I hope I'm wrong and am just being paranoid about battery.
I use 100% brightness except when I read iBooks. It lasts me more than 10 hours . I play a lot of Gameloft and graphics intensive games but I don't use wi-fi and 3G much. Probably the reason why my battery's so robust right now is because I've done a couple of recalibrating. When my iPad was new, battery life wasn't as awesome as it is now. This device is a beast. I'm so happy I've already decided to get the next gen.
Use mine moderately per day. About 45 minutes - 2 hours. The lowest it's ever been after one week of no charge is in the 70's of percents. And then I end up charging it all night. So no, my battery seems to be better than it was before. (even when I use strictly 3G for two hours straight, I see about a 2-4% drop).
