Wow. Look at the ThinkPad battery life vs. Macbook Pro

Message #1 - Posted 2006/03/22 - Charles Bouldin

What the devil is wrong with the Macbook Pro? The Thinkpad is showing double the battery life with equivalent performance, plus the reviewers make a note of how cool it runs....not a hallmark of the MBP. What's up with this?

Read the article very carefully the PC computers were running with an "Extended" battery, what ever that is. And the PCs were "optimized."

I saw those words; I have no idea what they're supposed to mean. If someone can tell me the watt-hours in an "extended" battery, that would be a start. As for "optimized", I guess we do need to know if the same powerstep (or whatever it is called) is being used in MBP and TP. A simple way to make a battery last longer is to slow down the processor, although I don't think that accounts for a factor of two or more.

Probably because the Mah rating of the batteries is different. Article doesn't state.

As for temperature, one machine is plastic, one is metal.

I had a look around the Lenovo web site. What a confusion of models and options! The ThinkPad X60 series has at least four different batteries available:

4 Cell Slim Line Battery 3.11 hours
4 Cell Enhanced Capacity Battery 3.55 hours
8 Cell High Capacity Battery 7.9 hours
Extended Life Battery 2.6 hours

The X60 batteries plug into the back of the laptop. The enhanced and high capacity batteries extend past the back of the laptop, increasing the size of its footprint. The extended life battery is a secondary battery which can be used in addition to the main battery. It's a flat battery which plugs into the bottom of the laptop, adding to its height.

It's not clear which is the standard battery supplied, but the model that Ars Technica reviewed came with the 8-cell high capacity battery and the extended battery. Combined these can give a life of over 10 hours, but they add to the size and weight of the laptop.

Ten hours of battery life is fantastic, but the X60 is really a sub- notebook and can't be compared to the MacBook Pro. The X60 only has a 12. 1-inch screen and has no optical drive. It also uses a GMA950 graphics chip like the new Mac minis do, which uses a lot less power but gives terrible performance by today's standards.

The extended battery is a special extra battery, that you can buy separately from the computer, that clips onto the bottom of the laptop. In other words, the computer that Ars Technica reviewed had TWO batteries, not one.

What does the ThinkPad weigh? What are its dimensions? If it's like other ThinkPads I've used, it will be substantially heavier and bulkier.

Anyone can double or triple battery life by making the case larger and packing the extra space with more batteries.

Ditto for heat. If you make the case larger, you can cram in bigger heat sinks and more fans.

Apple's fixation with small and light comes at a price. Whether you prefer small/light over more run-time/cooler is a matter of personal preference.
