what does it mean that the battery life is 4 hours? How does that work? It wouldn't even last through the night then?

Both the description and the person to answer your question are wrong. The battery life is 3-4 months, and it does require two AA batteries.

You can keep it plugged into an outlet all night. I've never even used the battery.

To clarify what others have said, the alarm unit can be plugged in permanently. The actual sensor pad that goes under the mattress needs AA batteries, and those last 3-4 months. There is a wire going from the sensor pad to the alarm unit, but that doesn't provide power to the sensor pad. There is also a low-battery warning on the alarm unit, so you don't have to worry about it dying unexpectedly.

Well, unfortunately I'm not an avid gamer so I am not on it that often, but I have found that if you have it in sleep mode it does a very good job of retaining power. If I were to estimate, if you played it as much as the average owner, I would say you could get a guaranteed couple days out of it...I might even venture and say three days. Again thats just a guess.You might wanna poke around online and google some sites that will give you some good insight on the battery life. Hope I was able to help at least a little. Have fun and keep gaming! ;)

I have been using this unit for a few months now and still get 4 or more hours from battery. Depending upon what I am doing some times more. Hope this helps you.

With mine I may get 3.5 to 4 hours maybe, never really timed it. I do know that when I unplug it and go outside, it seems like within a 1/2 hour to 3/4 of an hour the battery indicator is down a ways.

My manual says to charge no more than 24 hrs, I normally charge it over night and it works fine.

More than 2 hours actually. I left mine unplugged running at max brightness overnight to see how long the battery will last. I was up for more than 5 hours before falling asleep and it was still running. Light at max wasn't as bright compared to when it was plugged in though. There's most likely a circuit preventing the battery from over discharging as it turns on then off for some time still before I plugged it back in.

The battery doesn't last as long as the specs say it will, but then again, that is the case with all computers. I use quite a bit of CPU throughout the day, so without charging I would say it lasts 4 to 5 hours. Given the amount of CPU I'm using, I'm very please with that. If you are just using Microsoft Word and maybe 2 tabs of whatever browser, I would imagine the battery lasts much longer than 4-5 hours.

I charged it for 24 hours the first time. After that I just let it charge over night. You'll be amazed how long it lasts between charges. Hope this helps.

I have never used it past 3 hrs and there was no problem ...The company says a full charge can play for 5 hrs .. With a lot more hrs standby.

I get less than 2 hours of use on a full charge (mainly using for internet browsing, email, and playing mp3). The battery also drains when it's not on. I have the 16 GB linux version with advanced desktop enabled. This seems to be common. I think most manufacturers exaggerate battery life a lot, if it's not a flat-out lie. So 2 hours or less of use unplugged with this device is probably the norm, if the manufacturer is saying 3 to 4 hours. My experience with most rechargeable mobile devices is that normal real world use will not get anywhere near what manufacturers state for battery life.

It usually last for 2 hours. You should be able to get a second Battery, even a bigger one.

i am not sure..i would guess at least 3 years... As for how long the battery would hold a charge: Depnds on how you use it...I had the wifi on and was playing a 3D game for 2 hours with full display brightness and after 2 hours i had 40% battery left...i got tired of playing so I am not sure how much longer it would last.....you could set the display brightness to 50% if you are just browsing the internet and it may last 3 hours with wifi on.....

You lost 4% battery in 20 minutes? That's about 12% an hour putting you around 8.5 hours. Yup, that's about right. It doesn't matter what programs you have "running" in the background. The iPad OS works differently from your Windows OS, the stuff is there, but not running. It will not drain your battery any faster. The biggest factor is going to be how bright your screen is. I usually have mine around 40-50%, plenty bright for indoor use and my battery lasts 9+ hours. Also if you're reading a book turning off wifi will help a bit. 9 hours of continuous use is PHENOMENAL for a device like this. I constantly use my iPad throughout the day and I have never drained the battery all the way. My Galaxy Nexus on the other hand is abysmal; after about and hour of talking and a few texts the battery is at 60% it's horrendous. When I got my first smart phone (a Droid X) I was constantly obsessing over the battery life and if it was dying too quickly or if it wasn't going to sleep properly. I would look in the app market for apps that would help battery, spent hours researching charging methods etc. and it really took a lot of the enjoyment away from me when using the device. Then I learned to just not worry about it, if it needs charged, charge it. Bottom line, so long as you charged it each night before bed, you should never get even close to fully draining it in one day. Unless you're using it 9+ hours a day to which I would say you have bigger concerns then just your tablets battery life.

Im not sure what the battery life is supposed to be, but mine lasted easily 2 months on a single charge with an average of 1-2 hrs of use every day. They provide you with a charging cable for it, which you can charge from a usb port on your comp. The only annoying part is having it die when you're in the middle of using it, as the cable is not very long (1-2 feet, or something) and it makes it awkward to hold. But if you remember to charge it once a month or so, depending on how much you use it, you shouldn't run into that problem. As for replacements if the pen shits the bed altogether, it looks like they're sold for 10-15 USD Im not sure what the battery life is supposed to be, but mine lasted easily 2 months on a single charge with an average of 1-2 hrs of use every day.

Ours lasted 0 hours. Never did work. I waited too long to try to return it, and they wouldn't take it back. If you buy it, try it right away.
