How long does the battery last per session?

Since I was never able to get it working, couldn't tell you how long the battery lasts.

If you leave it on constantly then probably only 1 day it's a tiny battery. but if you only use it a couple hours a day it will last.

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

3 hours if you are using the maximum performance option, about 5-6 if you are on battery saver. :)

I used the battery on my last trip and had the camera on for long periods. It last for two days, probably around 8 full hours of use. Bought this as a backup battery.

It takes a small disc battery...I believe it's 3220. It lasts at least a month (of course that depends on how often you use it, and MOST importantly, if you remember to shut it off after each use), though occasionally it's much longer. Ease of use and practicality are well worth it.

Depends on the brightness set when on battery and how many applications are running. The brighter and more processes there are, the quicker the battery drains. If it's just for light use and not blasted on full brightness it should last about 3-4 hrs, at least that's on my laptop.

Not very long but long enough for a session, I just keep mine plugged in all the time when I'm not wearing it

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.

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.

I brought the laptopp for one friend. I have no idea of how long does the battery typically last. Sorry for the that

I can't answer your question because I have never had the battery run down in one recording session. I find the radio has good battery life in all functions, and it recharges quickly with a cable. I've had this radio for a long time now and use it regularly. I am pleased with it in almost every way. It is a great value and is full of easily usable features.

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.

It lasts for about 20+ minutes, but I don't use it for long except for short sessions. Please note, it's best when the battery is allowed to drained and then recharged to prevent memory effect. Most folks set it back in the charger which is the worse thing you can do.

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.

I can honestly say it has yet to run out of battery in one session... meaning I have had at least 2hrs straight and no low battery warnings...I just plug it in overnight and its good to go in the morning... I also have a dock for it though I never used it...its very convenient has far as weight it feels like a actual notepad...Im sure the internet has how long these batteries are supposed to last but from personal experience I

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.
