10 hours of battery life...really?

I didn't say I knew why, it's just that after a Mac charge my phone dies 2 hours before than it does after a wall charge, just saying.
I get so tired of this conversation. What apps do you THINK are "running in the background?"
I've timed mine and it tends to go down about 8-9% per hour of constant use, which would add up to 11-12 hrs (though I don't think I've let it go below 20% without charging). But then, I keep my backlight quite low - around 25-30% unless I'm in bright sunlight and need to turn it up to overcome the glare (which is rarely). I think that makes the biggest difference, I see an immediate change in rate when I turn brightness way up.
(Also, my wi-fi is on all the time.)

Maybe you always leave yours on, but for those of us who have used it both ways, we notice a difference.
Also, graphically-intensive games eat battery too. I observe this, so don't dismiss it.
Wall socket. Samywamy10 doesn't have a Mac
.I'll do this today in the first post.
Wifi only version, yep.
4.3.1
I'll try this tonight.
Watch this space...
> 11hrs iPad 2 wifi (5GHz n) running 4.3.1
Mostly reading and surfing in Safari, mixed with intermittent Mail, Scrabble, and Words With Friends. Brightness set at about 35% and automatic on. Bluetooth off.
Battery life is easily as good or better than my year old iPad 1.

still haven't charged my ipad since my last post here. Watched 2 movies and read some comics. it's also downloading a 400mb app right now...its hovering around 50%. So yeah, battery life rocks.
I definitely get 10 hours, maybe even 12-13. I keep wifi, location services, and push on all the time (I don't push or fetch email though) and don't charge more than once a week. I typically browse for 2 hours a day, streaming video for 30 minutes, and podcasts for 30 minutes per day. I have screen brightness at about 20 % with auto on. I also have multiple instant messaging services running for about 6 hours per day with push notifications.
For wifi-only models, does switching on Airplane mode increase battery life?
Can't see what real purpose it serves as when wifi is off, it's the same as airplane mode on is it not?

Brightness on full kills your battery. I run mine at about 10%. That's plenty bright enough for me.
Airplane mode means all of your wireless radios are off. Bluetooth, GPS, WiFi, Mobile data are all affected. Obviously there is no mobile data (or GPS) on the wifi only model. When you have any of these radios active, the ipad will continually search for a signal until one is found. If no signal is found, it will simply do an active search fairly often. If a signal is found, the device (if connected) will occasionally ping to make sure it is still connected.
For this reason, mobile devices in poor range of said signal tend to use more power searching actively, thus impacting battery life. Anyone with a mobile phone that has been to an area of poor reception can tell you a battery quickly goes in this situation. Same goes for WiFi and Bluetooth on the ipad (and of course mobile data). GPS not so much, as the device in this case is only a receiver, not a transmitter.
So in answer to your question, Airplane mode will help with battery life.
Do you have 3g enabled?
In my 1st gen ipad, without 3g on all the time, only wifi it would last 8 hours of use plus a few days standby. it is really amazing.
When i activate the 3g, just like my iphone 4, the battery life drops significantly. about 4 hours use and 10 hours standby only.
Depends of your operator and the signal strengh

I can't stand lower brightnesses. Plus I compared full to half brighness and there was only marginal difference.
Wifi only model.
Ok I've recorded my daily events on the front post, and I've let the iPad fully down charge and now I'm rev charging it. Let's see...
Hogwash.
ActiveSync works by opening a TCP connection (using HTTPS) to your Exchange Server and leaving it idle. New mail is sent as a reply to the established connection.
Blackberry BIS/BES works by opening a TCP connection (using a proprietary protocol) to RIM's NOC and leaving it idle. New mail is sent as a reply to your established connection.
Brightness on full is going to kill your battery life so much quicker even with auto-brightness on. Even though it is on it will never reduce it to even 50%. It will hover around 85-95% brightness. I run around 45%, sometimes less and I get the 13+ I mentioned earlier.
Agreed. The screen is the one thing that really consumes a lot of battery life.
The sure fire way to avoid worrying about battery life is to turn off the battery percentage indicator. Seriously, turn it off for a week and you'll stop worrying.
I think I'll still find the battery runs out at exactly the same speed.
Let me try turning the brightness down...
