Batterie d'ordinateur portable neuf se décharge très vite

Bonjour,

La batterie de mon ordinateur portable Lenovo relativement neuf (moins d'un an) se décharge extrêmement vite : 50 % en une heure. Que je sois en train de travailler dessus ou qu'il soit en veille. 

Y a-t-il un problème de paramétrage ou un programme qui draîne le PC ? 

J'ai produit un rapport powercfg -ENERGY, mais je ne sais pas vraiment ce qu'il me dit et comment remédier aux problèmes, si tant est qu'ils sont visibles sur ce rapport...

Mon ordinateur est un Lenovo Thinkpad Flex 5, 14ALC7.

Processeur : Ryzen 7, 7 5700U, 8 cores, 

RAM 16

Système d'exploitation : Windows 11

Le rapport powercfg -ENERGY dit :

Platform Power Management Capabilities:Supported Sleep States

Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

Platform Power Management Capabilities:Connected Standby Support

Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.
