It looks like you and I are having the same problem. I can only get about 3.5 hours out of mine now that I've installed Windows 8, and that's with minimum brightness, no backlight, and just doing web browsing. My CPU usage hovers around 5-10%, so that doesn't look like it's the problem. I contacted a CSR rep about it, who suggested I download my drivers through SW Update, since apparently the Windows 8 drivers for the laptop aren't available on the Samsung site itself. But still no luck. I'm pretty much out of ideas at this point - did you ever happen to solve the battery life issue?
Have you tried installing Easy Settings? If the Windows 7 version does not work, try downloading a different version from a Samsung notebook that ships with Windows 8. Not sure if this will work though.

I installed "Settings", which apparently is the version for Windows 8. Is there a particular setting I should be looking for?

Just FYI, the average power usage I see in a third-party battery monitor app (BatteryBar) seems to be about 18W when on battery, using the laptop as I just described. The number I see in Settings seems to corroborate that. Considering this is a 80Whr battery, ideally I should be somewhere closer to 10W idle in order to get the 7-9 hours people seem to be describing. Instead I'm getting about half Frown

Under Power Management you should able to select the 'Samsung Optimized' power plan and/or enable Eco Mode.

Well I tried that setting already but didn't notice a substantial difference. Killing a lot of background processes seemed to help quite a bit. When my CPU usage is around 0-1%, the laptop idles at about 11.5W instead of 15+W when it was under 5-10% load.

Still doesn't seem quite right, though, especially looking at the results okinawanmatt got:

I also ran a battery test. Set at full screen brightness with WiFi on, keyboard light on, and no dimming/sleeping, the laptop lasted 6 hours and 43 minutes when not in use. On a separate test with the same settings, I downloaded some apps, songs, burned a couple of discs and even ran Passmark, and the battery lasted 5 hours and 25 minutes. If I dim the LCD's brightness, I can see a possibility of the battery lasting about 9 hours on a single charge.
@okinawanmatt Your Series 7 seems to be doing a lot better on battery life than mine. I tried the same battery test (full brightness, full keyboard lighting, idling), and I get around a 16W power draw (measured in Easy Settings), which works out to about 5 hours of battery (in theory, haven't tested it), versus your almost 7 hours. What power settings are you using? What does your power draw look like in Easy Settings?

I'm sorry - I can't follow up on this because the laptop was a Christmas gift. I no longer have it in my possession. However, I repeated the same test about 5 or 6 times with the same results: over 6 hours, up to about 7 hours of usage per trial. One thing I did differently from other users in this forum was that I only disabled frivolous apps (such as the Best Buy advertisement app) that came installed with the computer; I did not attempt to re-image or wipe the computer or reinstall the OS.

As noted before, Samsung's power management app runs with precedence over the Windows power management, but if you start fiddling with the Windows settings directly, it clashes with the Samsung app and all of your settings can randomly change. So it's best not to open the Windows power management window and just let the default Samsung app control everything.

Windows 8 doesn't work on it. How many watts is your unit using on W7 and how much is it using in 8? On 8 it was using 20+ watts. There is no solution other than not to use W8.

Can't remember what it was on Windows 7. I installed 8 pretty soon after I got it.

How did you get back to Windows 7? Did you restore from a recovery partition or do a fresh install from a Windows 7 disc?

Me too. It is awful! I deleted the recovery partition, so I don't know what it was before, but it is now usually 3hr at 80%... I set it to battery saver.

I get about half hour less on win 8, so its not worth it to me.
