Battery time

hello,


I am owner of a MacBook Pro (13-inch, 2017) with BigSur and I am troubled about my battery's performance.

With normal use (text processing work + Music or YouTube) I get 2 hours tops of battery life before recharging. Battery health status is normal.

I have also regulated the options for max battery efficiency and keep a low luminosity on screen but still, the battery's life is much shorter than expected.

I am curious to know what's the average battery life for other same models. Moreover if mine's too short indeed, I would appreciate if anyone has a suggestion on how to fix this issue.

I have already tried reset sac and reset pram.


thank you

MacBook Pro 13″, macOS 11.4

   How battery health management helps

   The battery health management feature in macOS 10.15.5 is designed

to improve your battery's lifespan by reducing the rate at which it chemically ages. 


   The feature does this by monitoring your battery's temperature history and its charging patterns.


   Based on the measurements that it collects,

battery health management may reduce your battery's maximum charge when in this mode.


   This happens as needed to ensure that your battery charges to a level that's optimized for your usage

—reducing wear on the battery, and slowing its chemical aging.

   Battery health management also uses the measurements to calculate when your battery needs service.
