Drenaje de la batería durante la suspensión (MacBook Air): ¿procesos "powerd" extraños?

0

Mi MacBook Air de 13 pulgadas (principios de 2015) pierde aproximadamente el 30% de la batería todas las noches; la noche anterior pasó del 99% a medianoche al 73% a las 9:00 AM sin necesidad de abrirla. PowerNap está apagado.

Mirando a /var/logs/powermanagement , veo que powerd está haciendo algunas cosas por la noche, ¿es esto normal? La computadora portátil estuvo cerrada todo este tiempo:

EDITAR: Obtuve este registro de suspensión más detallado de la terminal:

... ¿parece algo relacionado con 'Mantenimiento del sueño'?
