I've had few 100% new laptops in my life. But with all of them I've the same issue... after 2 or 3 years of usage, the battery losses it's functionality.

I've had Toshiba, Macbooks (Air 2012), HP, Lenovo, MSI...

My usage is a lot of hours every single day, I think that is the root cause.

I use Linux+fluxbox, terminals and the browser, with powertop or TLP tuned. During first year, I even exceed the advertised battery performance, and multiply that of colleagues with the same laptop but heavier systems (gnome...)

But I'm worried I'm missing something, doing something wrong, it's at 2 or 3 years, that the battery reduces drastically the performance, and at 3 or 4 years it starts to shutdown unexpectedly (for example when it says there is a 45% still available, plop!).

One thing that I'm not sure if I do OK, is to try charge once I'm at 10% level... and when I'm on the desk, I always have the charger in.

I try to make full cycle of charge/discharge, full discharge from the BIOS (to avoid the operative system power savings), and different tips from internet... nothing helps, when I reach this state, there is no back. Any magic solution here is welcome.

20 Years back, I remember getting out the battery while working at the desk. But today laptops cannot do that. Also I see laptops announcing 20 hours of duration, battery upgrades, etc, but I suspect, that with same usage I will get the same issue.

Do you know any laptop model, or model+OS combination, that after 3 or 4 years of +12 hours of daily usage, still can be considered a portable computer and doesn't need the charger to work at least 4 hours? What is the best one after such a intense life?
