Hi everyone. I have a notebook and just bought a new Li-Ion-Batterie. To save lifetime I just want the notebook to charge it to 70% and discharge it to 10%. In the Setting Panel there's no such option. Is there a way to configure power settings in terminal?

I have never seem any software or notebook that will allow to control battery charge like that, normally the charge is controller on the bios and there are not setting to allow charge up to 70%. Where did you learn that will be the best option to keep the live of your battery?

Not sure what the best strategy to extend battery life is but you can definitely use tlp from linrunner.de to modify charge/discharge of your battery if you are using an IBM/Lenovo Thinkpad (called Battery charge thresholds). tlp and tlp-rdw are available in the official Fedora repos. (You also need akmod-tp_smapi, akmod-acpi_call, and kernel-devel).

For any other hardware, no clue what program can do this job for you. Check out the manufacturer's homepage!

@florian: Thanks I will check these commands out.

@aeperzet: It's written in the users manual. You shouldn't full charge a Ion-Lithium Batterie and also not discharge till 0%.

@posty:

  • What machine do you have there?
  • Where does the Wikipedia article talk about increasing lifespan using narrower charging/discharging thresholds?

@posty interesting reading, but as @florian mention, it will depend on the notebook you have. As far as I understand manufactures no not let you play with that, seems like there is an exception on the IBM/Lenovo Thinkpad. But great you asked about. Did learn a thing or two.
