E1705 extended battery how long on a full charge?

What would the expected life be on an E1705 on a full charge with the extended battery?

 

Battery

I have the 9-cell extended life battery with the e1705 being reviewed. The standard size battery is a 6-cell. With wi-fi off, screen brightness set to level 3 (of a possible 7) and using the e1705 for light tasks I got 2h 41m of battery life before the notebook went into forced hibernation which occurs at 5% battery remaining. For a 17" notebook that's actually pretty decent, but given the fact usage was light (some typing of this review was done) and wi-fi was off it was a pretty gentle test. If you were playing a DVD and had wi-fi battery life would likely fall to around 2 hours. With a desktop replacement notebook using a fast processor and high-end graphics card you expect battery life to be slim though. You could get bettery battery life by using an e1705 model with integrated graphics, brightness all the way down and wi-fi off -- but what fun is that? I say if you get a 17" screen notebook just be aware you'll likely be wanting to hangout next to a power outlet, and since these larger notebooks are mostly used as desktop replacements there's no doubt you'll be fine with that.

One nice feature worth mentioning is that there's a button on the battery that can be pushed to show how much charge remains. A series of 5 green LED lights on the battery will light up to show you how full the battery is, this is handy if you don't want to have to boot the notebook just to see what amount of battery life is left.

That's with the 7800 from: here



Battery

Being such a powerful desktop replacement notebook, I didn't expect much out of the standard 6 cell battery. With wireless and Bluetooth off and the screen turned to lowest brightness setting, the processor forced to its slowest setting of 1.0 Ghz, and Powermizer set to max battery in the Nvidia control panel, I managed to get 2 hours and 10 minutes before the computer went into standby. Under realistic normal usage I got 1 hour 47 minutes. On long flights I think I'll keep my laptop stowed away and read a book instead. The battery itself does have a button which you can press to show you the amount of charge remaining, even if the computer is turned off.

With the 7900. from: here.

If you need serious stamina you should look elsewhere, but it does get decent life for a 17" with a very powerful GPU. If you don't need the 7900, I'd look at a different notebook.

 

Hi,

with mine (9-cell), I get about 2h 30mins office/internet use with wireless switched on.

I get close to 3 hrs max but that's on low screen and wifi on
