what is the battery life of hours of use at one time?

This unit stays powered for approximately 5 hours on an ongoing basis when fully charged. However, it is VERY difficult to tell when it has (finally) fully charged. It takes forever.

Same as the other two responses, I have never used it long enough at one time to find out. I rarely have to change batteries though.

While I am not certain of actual hours, mine seems to hold its charge for days when on the shelf. But it is probably different if you are cycling it on and off.

I am looking at the battery life indicator now and it says 1hr 57 minutes, 54% remaining. So it looks like about 4 hours.

I might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

it is either one hour or indefinite. I use batteries in mine and use the one hour mode. I have to replace the batteries about every two months.

I can't give you exact hours but I can tell you that my sons use their players at campouts for many hours and I have never seen them go off. I have never used mine for an extended time on battery.

Ehh roughly 6-8 hours of charge time maybe, I don't even use mine anymore because I couldn't charge both at the same time, I also only used it when it dropped below 50% on my phone, just to get it back up to around 80%

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

8 hours is the correct answer. I love mine. Use outdoors where there is no electricity.

I would say the battery life depends on the display settings. With full illumination, I think it's about 6 hours.

probably about 3 plus hours -we use it for travel so it is usually being plugged in every night or during use. Never have had a problem with too little battery.

I bought one of these here in March, and although I try to keep it plugged to mantain the battery between 40% and 80%, I have used it for 6+ hours for web browsing, some YouTubbing, some Google SketchUp and watching a 80 minute movie (there was a severe blackout that time), from less than full charge down to about 15%.

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

I am sorry, but I don't know. It's been used for at least 3 hours in a row, but that's all I know. I never used it. My son did. I have since unplugged it.

Sorry, I've never really timed it. I know it is at least 4 hours, and maybe it is more. But the last computer I used had had a bad battery for so many years, that I had almost forgotten I could ever use a computer that was not plugged in. Not that it matters, but I purposely ordered this computer with Windows 7 because I did not want to use Windows 8 on a computer that was not touch screen. I have had the computer for about a month and haven't had any problems so far, unlike the person who wrote the previous comment.
