how long does battery last?

don't know, this thing doesn't work so we returned it immediately, don't waste your time. it doesn't amplify any sound farther away than your own voice, and you'll be afraid to talk because your voice will be crazy loud. Nothing else will be amplified.

Honestly I can't answer, because after I tried it the first day, I realized it just wasn't for me. It's still in the box it came in so the battery really hasn't been tested.

If you're wearing them constantly during the day about 8 hours a day, the battery lasts about 4 to 5 days.

at least 2 hours. maybe even 3. Its been a year now and I still have 2 hours remaining in my battery and I'm a student. So i've been using my laptop extensibly.

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.

Usually the battery last between 4 to 6 hours. Just make sure you don't drain the battery. When you see that the battery is almost gone, charge it to prolong the battery life.

Hi! As you said, it tends to consume the battery. About 8-10 hours. Sincerely,

The battery life has been great so far! I've had mine for two months, I never turn it off, and I use my computer for 8-12 hours every day. The batteries haven't needed changed yet.

Batteries last according to power consumption of usage. Anywhere from 1hr to 3 hrs depending on what your doing. Keep in mind that Core i7 processors draw more power when used at high percentage than most other processors.

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'd say mine lasts just under 3 hours at the lowest power levels. The battery is easy to remove, so you can always buy a second battery to double your life.

The battery on mine can last for about 2 hours with Wi-Fi turned on. There are three different USB slots (one on the side, two in the back).

Not long at all. Maybe 30 min from a completely dead battery. Lasts a good while too.

For me, so far, it has been lasting just about 2-3 hours on a full charge. Almost 1 year of usage so I do keep it plugged in when not in use and definitely overnight.

Battery life is generally about 6-8 months (at least in my case and there are two of us once/day). You get a warning on your phone if the battery gets low.

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

My battery usually last 20-24 hours if fully charged. I stream music for around 4-5 hours a day and it lasts almost the entire work week without having to be charged.

Where did you hear that? Of course not. I use mine daily and it usually lasts for 2-3 days based on my reading, web surfing and emailing activity. I let the battery completely run down after I first charged it and it lasted almost 11 hours. On average I get at least 10 hours of active use on it, but I usually charge it every three days.

I have run it for about 6 hrs before on a fully charged battery. Sometimes 7 depending on how often it is used. I keep a spare fully charged battery on hand just in case.
