Can the 5 hour battery life last longer if the brightness was set to 30-40% with the occasional web browsing in class?

Battery will last longer if Wi Fi is off, as far as brightness, it really doesn't make a huge difference in my opinion.

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 don't use it very often on battery power- however, I think there is a setting to adjust to " battery mode" so that it may be a tad darker but extend battery life.

I am even wondering: was this mess with the batteries intended to attract customers anxious to receive "unadvertised" bigger batteries just to boost initial sales? I am sorry for those who are now starting to receive the "standard" 4400 mAh battery. But I want to comfort you: even while I have the bigger 5800 mAh one, it seems almost impossible to me to drain even 60% of it in a real life student usage. I never carry an ac adapter with me anymore because I consistently get at least 5 min. per every 1% of battery power I have, with wifi turned on and on 60% of brightness. When wifi is occasionally off, it comes up to more than 6 min. per 1%. So, even if you will get 75% of this, it will still carry you through the whole day of classes and an evening in a starbucks. Anyways, I would not trade acer for asus even if I got smaller battery, because acer has unparalleled screen in terms of clarity and brightness.

Thanks very much for your response. I'm only getting about an hour or less of battery life. I'm very disappointed. Thanks again.

See the "release date for U50Vg-AM1" thread. A buyer got 3.5-4 hours. Very nice of him to provide this info as Asus is anything but forthcoming on the battery life of the backlit keyboard models.

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

Certainly, just lower the brightness if you are planning to spend many hours on spreadsheets, etc.

I have actually tested the battery life at maximum use. From fully charged, I had the screen at 100% brightness, and going online, I was watching videos. My battery lasted a little bit more than 4 1/2 hours before it went to 0%.

Regarding the battery life - Not true. My laptop gives backup for like 4 hours if I'm just browsing the net. I am currently a college student and all my classes are 3 hours long. I mostly use browser to search for stuff related to class (or chat on facebook :P ) and take notes on word. When fully charged at the start of class, i have like 30%-40% at the end of each class.No the laptop does not have back lit keyboard.

This works great on my early 2013 x230 laptop! I'm not sure if it works on the tablet. Depending on what I'm doing online with the screen brightness set around 60% I usually get 8-9 hours. I'm running a core i5, with 8 gigs of ram and a 256 gig ssd.

I've had mine about a year, my husband has had his for just a month or two. I watch some videos but mostly read books or look at bbc news or pinterest so brightness is up about halfway most of the time. I think it lasy fully charged for about two or three hours using it nonstop. Longer if im reading books already downloaded (like on the plane) chrged in about a 45min or so if its turned off, little slower in airplane mode. Note the brightness and things like gps location and wifi searching constantly use power in the background just like your phone! Turn off everything your not using :)

Yes, you're right, thanks! Now that I read it more carefully apparently you can also adjust the brightness level on the MB 371 to help conserve battery power.

It depends on the computer you're using it with, your screen brightness, whether or not you're on the internet, watching videos, have the volume turned up, etc. I get about 2 hours average, which is about 40% of the 5 hours I got on the Lenovo brand battery that came with my laptop.

You can adjust backlight of the LCD screen to save power + You can get an extra battery (4 hours)

In my tests about 4-5hrs under casual use over WiFi. (Browsing, writing, image editing)

Yes, about that long if you have the backlight on. I discovered that turning the backlight off (F1 key) will allow it to last all day on a single charge.
