Power manager should implement options to extend battery lifespan

Many third party utilities (like Lenovo thinkpads, etc.) implement algorithms to increase battery lifespan (viz the amount of time you can use a battery, before you have to replace it), especially when laptop is plugged in to mains power -

Battery lifespan is highly dependent on charging behavior - a continuously charged laptop will need to replace its battery more frequently than one with smart charging.
In linux, it has been available to a limited extent using the TP_smapi package, viz no longer available in Karmic (

The power managers should have options available to extend battery lifespan - it would be an extremely cool and useful feature for all of us who use laptops.
Solution #2:
Power management Profiles on Battery Power
I am relatively new to Ubuntu and I understand that in Lucid there are plans or already an implementation for better power management. As I haven't seen the alphas myself I thought I would suggest a few things. Sorry if these are already being implemented and this is redundant. This site:
http://salcher.posterous.com/?tag=ubuntu suggests a few ways to optimize batter life using Powertop and manually configuring files in /etc/laptop-mode/conf.d/. I think it would be great if there was a GUI front end for this that allowed adjusting of the settings and creating of various profiles (rather than editing .conf files directly). Similar to the Power Management functionality included on Acer laptops (ie clocking down the processor, disabling card buses, USB, ethernet, wireless, etc.).

Solution #3:
Build charging-control directly into kernel

Something as tied to hardware as controlling when the battery charges and when it cuts off should be built into the Linux kernel itself, not tied to a desktop enviroment!
