Win 7: netbook battery killer?

Win 7: netbook battery killer?

The Toshiba NB205 dropped a whopping three hours battery life when running Windows 7 - although this is likely a driver, rather than OS, issue.

You might be looking forward to the official availability of Windows 7 with bated breath, but netbook manufacturers could have cause to grit their teeth if analysis into comparative battery life with Windows XP holds true for the finished product.

In a test carried out by Laptop Magazine, laptops and netbooks were given both Windows XP Service Pack 3 and the latest build of Windows 7 in order to compare performance between the two. While the laptops were almost unaffected by the change, the same couldn't be said for the netbooks.

One of the devices on test - a Toshiba NB205 - was capable of running the battery benchmark test for an impressive 9 hours 25 minutes under Windows XP, but this dropped by over three hours to 6 hours 15 minutes once Windows 7 was installed. An upgrade to the drivers available from Toshiba clawed back half an hour, but the result was still heavily in favour of Windows XP.

Another netbook, the MSI U123, told a similar tale: with 8 hours and 14 minutes of available runtime in XP, a move to Windows 7 dropped it to 7 hours and 41 minutes. While this represents far less of a dramatic drop than the Toshiba suffered, it is still likely to disappoint anyone looking forward to the next generation of Windows 7-based netbooks.

The blame is unlikely to fall entirely at the feet of Microsoft's latest operating system, however: a lack of mature drivers for much of the hardware in the netbooks is more likely responsible for the dramatic drop in battery life in the Toshiba, as evidenced by the half-hour increase seen once newer drivers were installed. As we approach the official launch date of Windows 7 - and certainly as manufacturers prepare netbooks with the operating system pre-installed - we should see the quality of drivers improving, with the battery life reaching the dizzy heights that were attainable under Windows XP.

There's more good news if you're still looking forward to Windows 7's release: despite the loss of battery life, the test revealed a noticeable increase in hard drive performance and the time applications took to open under the new operating system.

Do you think that Windows 7 will be the operating system that saves the netbook market or kills it? Will you be upgrading your portable systems when the official release rolls around? Share your thoughts over in the forums.

Six and three quarter hours is still almost good enough for a full working day. I'd say it's a price worth paying for getting a much more modern, stable and secure OS. Hopefully further battery life improvements will come soon.

Shorter battery life, but improved performance. So in other words, do the same amount of stuff, just quicker. Thus, leaving more time for the pub.

Windows 7: the OS of the drinking man!

Shock! Horror! Drivers for unreleased beta OS not quite right!

On that particular netbook, others don't have as big a battery or battery life, my netbook lasts 5-6 hours a 30-40% drop in that is going to see its portability significantly reduced.

All that said Win7 is likely to be fixed by the netbook makers whereas I see a similar drop in battery life by running Ubuntu on my netbook and I doubt anyones going to fix that for sometime, I choose to run it as generally it makes the pants Atom platform perform a bit better.

Buying a netbook was probably the worst hardware choice I've ever made, people bang on about low power use etc. but my eeepc 1000H uses the same ~1250mA/h in Xp as my core2duo notebook does in powersave mode and the notebook with a bigger screen and more grunt despite lower CPU speed is much more useful.

I have 7 on pre-order and am hoping that it can provide the multitasking performance of Ubuntu to my netbook along with the powersaving abilities of XP, guess only time will tell.

To be honest, I didn't leave XP on long enough to be able to test the difference. My Compaq Mini works just fine with Windows7 RC as I have power adapters at work and a couple at home.

I don't believe anyone uses their netbook for a full days work completely mobile. If they do, then they will have gone for a 6 cell option and power adapters in car.

I have noticed when I am mobile and sharing my internet connection on my htc touch it does use up the battery a lot quicker. Again, that might be early driver issues.

Thats probably because its charging your phone via USB whilst the phone providing the net connection, my mobile does that too.
wuyanxu 26th August 2009, 11:27 Quote
did it have aero enabled? if it does, that should have fully loaded the netbook's tiny GPU, which is why it is so power hungry.

either way, win7 will be much better than XP. who still uses an OS without a native start menu search?

Why is it that people trot out bilge like this?

Let's analyse this in reverse order. Secure? I didn't have security issues on Windows 98, let alone 2000, and I don't on XP. It's difficult to see how a new system can reduce the level of security problems below zero.

Stable? The only thing that I have stability problems with is Firefox, darling of flower-dancing hippies everywhere. It's getting so bad I'm thinking of going back to Explorer. Yes, seriously.

And modern - oh, I can't wait to get my teeth into this one. You want to promote something merely on the basis that it's more recent than something else, even though it's demonstrably less good?

Ooh! Ooh! Ooh! Microsoft have released a new operating system! Ooh! It's obviously automatically better than anything they made before, even though it's clearly vastly worse, simply and solely because it's the latest release! Ooh! Ooh!

For pete's sake.

I never said it could reduce security issues to zero, only that it is fundamentally more secure design than XP. The driver model is more stable than XP and it is certainly more modern. So I fail to see how what I wrote is "bilge".

Never said you could.

I said security issues were already zero, which is quite hard to improve upon :)

There's no such thing as zero security issues.

Anyway, enough of this flaming.

Wow, where to start! It's easy to say Windows 98 was secure when the amount of viruses etc. written wasn't even close to what it is today. I understand that you don't get viruses, neither do I, but we know how to use a computer and the internet in a safe way. The same can't be said for the other 90% of people out there. Next we have UAC, and now that it actually works how it should (unlike Vista), vastly improves the security of 7 over XP or anything before. Programs have also finally been denied access to the kernel. This caused allot of problems for anti-virus programs during the beta stages, but it's the right way to go in terms of overall security.

Next, we have what l3v1ch touched upon, the improved driver and overall stability of the OS compared with XP. Running Windows 7 at home and XP Pro in work has made me realise just how much better Windows 7 (and Vista) is. I'm not talking about blue screens here, I'm talking about how XP often get's bogged down whilst multitasking etc. (ok my home pc has better spec, but my work pc still has a dual core processor etc.). The way Vista and especially Windows 7 handles programs that stop responding is in another league to anything before. No longer do we have to wait 10mins+ till things are sorted out and the crashed program is closed, it's instantanious if we don't wish to wait and see if it'll sort itself out.

Also, modern in my opinion is important. Afterall I spend most of my day staring at an operating system, why not have it look nice, especially as in Windows 7 it's now more responsive and quicker than any other Microsoft OS before? I understood why people hated Vista, but with Windows 7 there really is no reason to bash it. It's faster, has propper 64bit support, prettier, more stable, quicker to boot etc. etc. than XP or 2000 ever were.

Sorry for the rant, but Rhodes dove in and insulted l3v1ch, and it appears without even trying Windows 7.

As for the original story, I'm sure things will be sorted by launch as drivers improve. But as wuyanxu pointed out, on such low powered devices (especially GPU) they may use more than XP does.

It's a driver problem.
On my laptop I have the same problem. Windows 7 64-bit say 6 hours instead of 7 hours and half (Vista 64-bit) (wireless on, minimum brightness), as for some reason my CPU is supposed to go at 800MHz, but instead when on battery, it goes at 1500MHz minimum, but plug-in at "power saver" mode, it goes down to it's 800MHz, so plug-in uses less power then when on battery. The reason for this is that I dont' have my motherboard drivers installed, but rather using Windows default drivers. In fact, no mater what I do with the system, it won't increase battery life, as nothing actually goes under power saver mode when on battery, except for the GPU, and the GPU is the only drivers I could find (using Vista 64-bit drivers gave me BSOD's)

It makes no difference whether I use 7 or XP on my netbook, I still get around an hour and 3/4.

I much prefer 7 - quicker to boot and generally doing stuff. UAC is a lot less annoying.

its obviously a driver issue, how can win7 be blamed. its not like the architecture between vista has changed that much, that a 3hr drop in battery performance would occur. most probably the processor not throttling down even if you are not doing anything that's why it dropped that much

Playing the old Let's-Blame-Microsoft game, are we?

Calm down, wait for retail release, give it 3-6 months to sort out driver issues that shouldn't occur but still do, THEN start blaming MS.
Thank you very much.

what goodbytes pointed out is probably the issue.. if the power management is bunked- funny though.. it runs good on netbooks and it's forcing itself into a high performance profile.. hmmm

think it's probably like that on purpose.. lure in the choobies and then hook em lol turn it all off and then listen to them squeel like a pig

I have to disagree about it killing battery, Im using Windows 7 Ultimate RTM on my ASUS EeePC 1000he and on power saver I still get 9.5hrs and on super performance I get 5.5hrs on average.

It was connected via bluetooth not USB. Still I'm happy with the performance regardless.

Properly configured, you can still get some very good battery life figures out of Windows 7 on laptops and netbooks. However, you have to set them up as such. If you install all the features and widgets and fobs that you would do with a desktop install of Windows, of course it will get lower battery life. If you install it with a feature set that keeps the fact it is a low-powered portable in mind, and you set your power settings as such, you will get a lot better result. Once we see some profiles coming out of OEMs and more drivers from manufacturers, then we might be able to take better stock of how good battery life is or isn't. These machines have drivers and profiles that are tuned to XP, so we would need to see installs and drivers for these machines tuned to 7. I think the title of Battery Killer is a bit overblown, if not purposely inflammatory. I wouldn't pass judgement quite yet until we see final builds with proper native drivers and adjustments.
