In my experience, if you are using your notebook with full brigtness, normal workload, it's around 50%of the claimed battery life.

If you are using it under full load, (playing 3D games and full brightness) , it is around 1/3 of the battery life.

Buy if you use min. Brightness and disable Bluetooth, wifi and just use Microsoft Word to type a document, it is possible to reach the claimed battery life. ]]>Mar 14th 2009 9:32PMhttp://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/http://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/Mar 15th 2009 3:28AMhttp://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/http://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/

We need a widely-used cross-platform application, like a Firefox plug-in perhaps, which watches the battery charge-discharge-recharge cycle, and reports statistics back to a central server. It's utility would be to warn the user when their battery has begun to behave less than par for a battery of it's age, in a PC of that particular model. It could even warn when the battery is giving signs that it is about to fry. Some batteries can even be polled for their serial number and temperature, along with remaining charge, etc. The user would provide the purchase date and purchase source, so the source of substandard batteries can be tracked throughout the population.

I'm sure the battery manufacturers would attempt to use DMCA to squelch the truth, but it's important to provide the public with an unbiased, independent source of data.]]>Mar 14th 2009 7:24PMhttp://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/http://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/Mar 14th 2009 8:13PMhttp://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/http://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/You should be on some senate committee..

AMD guy kinda bashes that program.
Apparently the industry uses the least active workload.

The type of battery that resides in most laptops today, lithium-ion, lives a much longer life when NOT fully charged, yet the simplistic battery management system (BMS) in our computers just tops up the charge until full, then holds it there as long as you are plugged in.

For those who rarely untether their laptop from our clean-coal grid, I'd like to suggest that the battery power mode selector have a new option nestled between max-performance and max-run-time, that of baby-my-battery. There are well understood methods of extending the life of various battery chemistry, so my idea would be a very simple software implementation, virtually free of charge to the vendor (I'm so punny, I know).

Of course, an algorithm to extend battery life would have a couple of downsides for both users and industry, namely that of forgetting to top up the pack to full before leaving (it would likely float between 40-80 of capacity), and not having to buy a new pack for the life of the computer. A minor inconvenience on one hand, and a better use of resources on the other - sorry industry, but plans for infinite expansion and profitability are not logical in the face of a finite resource base.

You can bet that we'll see pretty sophisticated charge algorithms in the coming wave of lithium powered hybrid cars, where the pack life is a make or break business deal. The Prius already uses a BMS to hold its battery to within a few percent of optimum, hence we have these cars running on NiMH packs for a decade or more in many instances.

Somebody, please make my idea a reality - I'm not smart enough to do it myself.

You want real world figures? Wait for a laptop review. Places like notebookreview.com is a good example. They give real world figures on notebook performance and then just go to the forums and start monitoring what people are saying. The net is a wonderful place to get this info....but it does require some looking.

1) Full use of everything. 100% CPU, Disk IO, Bluetooth, Wifi, Sound, etc. Just pump random data to everything.
2) Play a DVD in a loop until the battery dies.
3) Browse the top 100 sites in a loop saying at each for 15 seconds.
4) Same as #1 only 50% to everything.

This reminds me a lot of Blackadder's infamous "Disease and deprivation stalk our land like... two giant stalking things."

The problem is we accept a lack of standards with such profound arguments as "read a review". Seriously? I can't see why anyone would disagree with the argument being made here-- anything that makes things clearer for purchasers is a good thing.

Intel and AMD don't set these numbers.. HP, Toshiba, Lenovo, and Apple do.

I guess I must be a corporate suit, when I see Intel's point that cheer leading an idea about this on a blog post versus getting the entire industry to change together makes little sense. unless of course you want to be a cheerleader instead of an industry leader.]]>Mar 15th 2009 8:58AMhttp://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/http://www.engadget.com/2009/03/14/amd-proposes-new-laptop-battery-life-metrics-intel-is-like-wha/
