If the Wi-fi is on, it will not last long. Two hours i think. If turned off almost six hours of fun.

From full charge, the battery typically will last 1-1.5 hours with continued usage.

The battery lasted multiple times of me using this keyboard for several hours. You have to be careful to turn it off when it is done. I haven't had to replace the batteries yet, though, and I have used it maybe 5 times for 2-4 hours each.

I've had it last as long as 1-1/2 hours on a continuous run. Pretty fast charge via mini USB, too.

I never let my battery die completely, but I would say it lasts on my laptop about 4 hours.

My battery last for a while. About 2-3 months, but I think it depends on how much it has to be used. The batteries are cheap at Walmart.

Hi,I have mine since two years ago, the battery had a duration between 2 and 3 hours, but since one year ago it last around 30-45 min.

It depends on your performance settings and what you're doing on the laptop. I use mine with high performance and generally use light programs (MS Office) and web browsing and it generally lasts about 2-4 hours depending. The life of the battery can extend quite beyond that I believe by turning off features and downgrading performance, but I have not really explored those features fully.

Mine has lasted for several years ... it has a built in rechargeable battery. I only charge it once a month or so.

I'm still on my first set of batteries I put in it (2 AAs) and I'm amazed they've lasted this long. I've been using it off-and-on both day and night. The other night I fell asleep with it on and expected the batteries to be dead in the morning. They're still going! I turn the radio off when commercials come on so I'm sure that helps, but still, I've been pleased with battery life for this radio.

When I am on a trip and making lots of pictures it will last most of one day but if I am just making pictures occasionally it will last for days or weeks depending on how often I use it. I am sorry but can't answer how many hours. I always carry a backup battery with me in case it runs out of power. It does keep its charge longer than off-brand batteries of equal size and is now the only brand I use.

Battery life is pretty good. I keep one in my car with a rechargeable AA and it'll stay good for about 3-4 weeks until I start noticing it get dim. But that's only about 4-7 uses out of that time.

I've had it for about a month now and it still runs good as new. Battery life lasts about a week if used constantly.

Overall the battery life is good. For a heavy user like me it lasts for 2.5 to 3.5hrs. its good. the only drawback is it has a inbuilt battery. which means its not user replaceable.

It's pretty good... I got up to 2 days use with mine without charging. And when I gave it to my friend in Africa.. He never complained about battery life despite the fact their wasn't steady power supply where he lives.

I use it on the bus to work, my commute is short about 45 min.; the battery last for about 4 days. After using the on, off, volume up/down etc. for a period of time, the printed data dissolve.

I have no issues with this battery. I run my laptop for hours at a time typically, so I keep it plugged in. If you were to run as little as possible, I'd say it would probably last an hour or two.
