Xoom Battery Life
Anyone who owe an iPad prior to the Xoom can comment on the battery life? On the iPad, I can go on a week or two just on general browsing w/o having to charge. Just the tap to the top power and the screen turns off, not shutdown.
On the Xoom, how long does it last on general use? I know the spec said up to 9hrs, but I am more concern on general usage w/o having to do a full shutdown.
(assuming I get WIFI version, so with 3G turned off for those with 3G now)

I thought the spec was over 10 hours of constant video playback on the XOOM?
Anyway, I flew back from Singapore on Sunday/Monday of this week. It's about 20 hours. There was on-board WiFi, so I was able to do emails, browse, read, write, etc...
The XOOM lasted the entire trip with power to spare. Granted, I stopped using it while I ate and watched an on-board movie, but I was at the XOOM for well over 10 hours. I'd put my usage at a minimum of 11.5 to 12 hours and a maximum of 14 hours. I think the time over 10 hours is accounted for by the time most of the unit was in standby while I was either reading off it or writing into it. The core goes to sleep and peripherals are powered down when not used.
I can't be more pleased. The screen was great... absolutely no eye strain all that time. The only downside was a three day kink in my neck from looking down in my lap for so long. I'll know better for next time and prop my hands up on pillow or something.
In the end, I can attest to the advertising slogan "Grap it and it grabs you". It has certainly grabbed me.

Have you let the battery drain down to 15% or below (red LED)? Batteries need to be exercised. They can lose capacity (or never achieve full capacity) if they are never allowed to drain all the way down.
Batteries can also be damaged if they drain down too far. Theoretically, the on-board battery manager should protect the battery from this, but I stop using and start charging when the LED turns red. BTW, I rarely charge before the red LED shows up. This ensures the battery is fully exercised on an on-going basis.
My XOOM usually goes about two or three days with my normal usage before it needs a charge. I've haven't logged how long it is in use over that time, but it's easily more than twice the time you are getting.

My family and I are getting ready to fly to Europe this summer for a long vacation. My son and I got Xooms. Not only for our trip but just general usage. I have ran the battery down at least twice doing normal browsing and watching movies.
At my desk at work,I have turned off the 3g/wireless and dimmed the screen all the way down. then I fired up a movie and let it play all day long at my desk over and over again. After 9 hours of being the office with movies playing all day, I would leave with about 31-34% left. I plan on doing a test with the screen on auto and wifi turned on as well as the movie playing all day to see what it looks like at the end.
I have no idea how long a flight will be from Chicago to London, but I hope to have enough to cover at least that trip and still have some juice when we arrive.

I need some advice please :
I noticed some bizarre, random behavior on my xoom, after turning on the device, when I check "battery use" in "settings" it shows around 90% for display and the remaining for some other apps, but last week after I charged it to 100%, went out for a few hours and when I was back and checked the device, was surprised to see 87% left on my charge (without using it the whole time). I checked the battery use and the funny thing is it showd 35% usage for the display, 58% for android OS, and the remaining for other apps. I turned it off and back on, and everything was normal again. This happened again today and this time, in addition to "android OS", some app "mobile data" was also using much battery. (I use a wifi only xoom)
Any idea what causes this, because one expects the display to use the main part of the battery, not the OS or any other app.

We have a 3G iPad (original) and a wifi Xoom, both with wifi always enabled. The iPad definitely lasts longer, but not by a huge margin. When it comes to recharging, the Xoom is noticeably faster, but again not by a huge margin. I don't have an iPad 2, so I can't comment on the newest generation iOS tablet, but I imagine the results would be comparable.

I use my xoom heavily. In fact the only time I am on my computer anymore is to transfer doubletwist content (wish they would make a dasktop like client for 3.0) and to transfer movies onto it. I can go three days or so on a charge depending on how much video watching and playing with the games I do it may go longer granted I run my battery down to 10% or so shut it down and charge. It takes about an 1.5 hours or so to fully chargeband then I am good to go again. How that applies to other devicees and there life I can't say.

Standard use, I get about 9-10hrs on mine... and by standard I of course mean Web browsing, Gaming (lately it's be WSOP - not sure why), email and video chat, and browsing the AC forums. My contrast is set to about 55-60% and my updates for programs are every hour.
