Hello, i have thinkpad t14 gen 3 which is supposedly ubuntu certified. I uninstalled windows 11 that came with it and i decided to install ubuntu 23.10. however, i noticed that battery life drains much faster when using ubuntu (like 1% for every 2 minutes while i was just browsing using firefox).
I tried to figure out the issue but couldnt find it. Then, i decided to install linux mint debian edition (lmde 6 faye) and suddenly i am able to get much better battery life. I even installed windows 11 again (tripple boot with ubuntu and lmde 6) and i can confirm that i have about the same battery life between windows 11 and lmde 6.
So, why i cant get the same amount of battery life with ubuntu? In the beginning i thought it was linux driver issues, but then, i could get a much better battery life with lmde 6 which is also debian like ubuntu.
Btw i use the AMD version of thinkpad t14
