Windows 7: Battery Life

Battery Life

Hi everyone!

I couldn't find a discussion on battery life in Windows 7, so I decided to create a thread.

I recently installed Windows 7 Build 6956 on my laptop to try it for some time. I'm liking it so far. Using the Balanced power option in 7 I'm getting maybe 20 minutes longer battery life compared to using the Power Saver option in Vista. I'm guessing this is a good improvement since Balanced still allows full performance when needed and Vista cuts performance. I haven't tried Power Saver in 7 yet, but I guess it might give me a little extra time.

Has anyone else timed their battery life?


PS: I also noticed a difference in wake up time from sleep when I open the laptop lid. Windows 7 takes just a second to wake up and Vista takes about 4-5 seconds. Has anyone else noticed this difference?

Hey hethoofd,

I havent got around to running 7 on battery yet, but yes I am suitably impressed by Startup, wakeup, from both sleep and hibernate and reboot times.

The power saving that I have seen so far seems also pretty impressive. I am mainly surfing the forums not the best of tests but it does allow me to see how 7 switches down during periods of inactivity.

When I get around to using bat I'll let you know

Hey pooch,

The wake up time is great improvement for me. I hated how Vista could take 5 seconds to wake up!

I'm going to try Power Saver mode to see how long the battery lasts. I'll post my experience here.

At the MSDN Developer Conference, the Keynote speaker was Ron Jacobs - and he covered Windows 7 for 10-15 minutes - and that was one of the key points made - Windows 7 runs faster *and more efficiently* than Vista. It uses less resources, less battery (or, rather, it manages the battery life more efficiently) and provides more in hte way of a UI for the user to enjoy.

I already have Windows 7 running fulltime on my Dell XPS M1330. I find the battery time is a lot longer. As well I would have to say the wake up time is way faster. I am so impressed with Windows 7 that I gave up my Genuine Vista for this. Most my friend still say it's a glorified vista but they haven't even tested it themselves yet!!

Windows 7 is probably going to be the first microsoft os that I would consider paying full price for and by that I mean not buying OEM.

Hey Linuzo,

I have to agree with you. I find it just feels right, from the smooth install through to the responsive handling, good looks and the fast up/down/wakeup times.
I am not as brave as you, but I have come very close to throwing Vista off and trying a raid install.
Maybe soon

I wanted to post back as well about my experiences on battery and then forgot
I was getting about 15 mins longer with my HP 6720s lappy, between 1hr45 and 2 hours on a full battery.

Not to be sniffed at
