Celeron battery life

[CaptainPinko]

does anyone know how modern Celeron Ds compare with Pentium Ms for battery life? The question is whether Centrino is worth the additional cost over a Celeron D laptop for the added battery life / performance if any.

the battery life is about the same, the performance falls in favor to the centrino, the p4 cores obviously are going to outperform the celerons though

those buying bargain laptops based on celeron chips be warned though, if its not the new cores such as the celeron D, they are not capable of frequency scaling and have terrible battery life because of it

I've got a centrino, and it's battery lasts almost 2 hours if I'm not gaming on it :)

Normally you should see longer than that, typically 2.5 to 3 hours but my system is a gaming notebook so it chews through the battery pretty quickly.

As for the advertised times, anything over 3 hours is complete and utter bullsh*t. Unless you're lugging a 5 pound battery in a saddlebag that is...

As to the performance, they just don't compare. It's like comparing a 386 to a current P4 processor. The celerons are slower and inefficient (as well as heavy from the ones I've seen in stores). Personally I'd go for the extra cost, the performance and battery life is worth it. However, if you're tight on cash celeron is a decent way to go, just be wary of any gaming you might be planning on.

hmm, thats really unfortunate. performance is nice but battery life is more important. I have elctures that last 3 hours with more classes afterwards. are there no laptops with decent battery times? I've had semesters 8 hour days so for 2 hours it's really not worth bringing a laptop if you are gonna hafta take paper notes too.

now some of my classrooms have plugs for laptops but this is for my student how is going into Translation so the rooms are likely older and not computer friendly.

ATOM Speedpad, it's pretty expensive, but it can power things for a long time. I'm pretty sure that would do for what you seem to be getting at.

Now that doesn''t make it student friendly... *sigh* couldn't someone release a laptop with AMD Geode processors or something? Well, back to comparison shopping...
