J'ai compris pourquoi la batterie descend si vite.
Le proc n'est jamais au repos, le "system loading" n'est jamais sous la barre des 30 % !
Même si je baisse la fréquence du proc.
Sur ce lien, il parle de surchauffe du proc (jamais sous les 70°C pour moi) :
https://doc.ubuntu-fr.org/macbook#surchauffe_cpu_a_70
Mais je ne comprends pas ce que je dois chercher dans la commande donner ...

Ça ne me parle pas beaucoup :-(
Une idée ??
