Pretty good, I think; it belongs to my brother. Maybe not that good compared to newer ereaders, but long compared to phones and tablets, as far as I know.

My Asus Transformer has been on currently for over 62 hours at this time. No problem.

Casual use (Intel graphics, brightness at like 50 or 60) about 8 hours. Battery life with gaming (Full brightness, Nvidia card) about 2 and a half.

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.....

I haven't tried to run it all the way down since the laptop is usually stationery except if I move around the house with it but I know will last at least 35-40 minutes and not still had around half battery according the battery meter on the taskbar. This is the 2nd battery I have purchased. The 1st one was for a laptop for my mom a while ago and it's still working but again that laptop is not used that much off house power. For $20 bucks I'm satisfied

Well, besides the slight differences in the model of processor and other internals, the main difference that would make The $100 difference is the second battery which comes with the 6640. It also has a very nice suede-like case, an external mouse, and a cat-5 dongle and an HDMI dongle. I don't know if the 6447 has any or all of those, but it does not have the 2nd external battery, which is GREAT....it fits on the back lower edge, raises the back about 3/4 inch and extends you battery life without being a bother. Both batteries charge with regular AC cord in one port, first the internal battery , then the external. The external has a light showing % of charge (or remaining amount) in 20% increments. I would pay the extra for the extra battery time. No battery ever lasts as long as the specs say. The laptop with the external battery fits nicely in the provided case (its more like a sleeve, very thin, not bulky...but elegant! Hope all that helps.

I haven't had mine long so I haven't worn the battery down, but in-the-box new my laptop has been lasting about 4 hours while playing Steam games, so it's pretty decent.

on a full charge, my battery - the original that came with the computer, lasts 2-4 days. But I shut mine down at night, so it's not running 24/7. But it is on when I'm working.

I have the same laptop, and have been using the battery for about three weeks. So far, so good. The battery life is definitely lower than the original battery, but I didn't keep in-depth stats on the original, so it's hard to gauge. I get about 1.5 hours of life out of this battery when watching movies.

I just got the 16GB for Christmas. After reading all the battery posts, the first thing I did was charge it fully, then play it until the battery died. I got 20+ hours. I think a lot has to do with how often the screen is "lit". If you're constantly shuffling through, picking songs, adjusting volume etc. i think one would get less life than just playing it like I did (the screen was black most of the time since I wasn't adjusting anything). And of course, i would expect video or games to kill the battery even quicker. That would be a good test, play a video straight through and see the life. I don't have any videos loaded, so I can't really test that. I just got the 16GB for Christmas.

I suppose it depends on how intensively it's used. I play games for about 30 minutes every day and the charge lasts about 4 days. Streamed video for more than 1 hour and it might have consumed 40% of battery life.

Have had ours since September and have had no issues; daily use of 4 to 6 hours. Just keep in mind computers are like cars, every batch can have a lemon.

About3 to 4 hours. Battery isn't a strong point here. I didn't buy it to use the battery however, so I'm pleased with it. Really a grade A laptop. I'm sure this varies based on task and performance settings.

My 120 lasts about 12-14 hours with normal use. I listen to a podcast, playlist or ripped CD and then I change to something different. So I'm using the touch pad and having the screen light up about once an hour. I have the screen backlight set at minimum and set to turn off after 15 Seconds. I think I should get more hours than that out of it. It's certainly NO improvement over my 80!

Hi.I have owned this laptop for a couple of months now and it is amazing. The average battery life I am getting while running wifi and having the brightness about 3/4 bright, I am getting 5 1/2 hours. With wifi off running regular programs like Word, Excel and Powerpoint, I am getting about 6-6/12 hours. Amazing battery life
