Macbook Grinding AFK Overnight while charging.

If i leave my Macbook Pro M1 Chip 2020 Model, running overnight and while the charger is plugged in with the macbook is sitting at 100% all night, I set the graphics to the lowest and keep my brightness to the lowest where the screen can barely be seen. Lets say i leave it around for a month non stop every single day 24/7 while its on charge and lowest graphics and lowest brightness possible, will it damage the battery in any way or the macbook itself and will it impact elecrticity bills by a chunk?

Hi deeyan224,


The amount of electricity and battery health you consume has many individual variables. In this case here's some information about the different modes available to help preserve your battery over time:


"Customize battery settings. You can set different options for your battery in System Settings.

  • Optimized Battery Charging: This feature helps to reduce the wear on your battery and improve its lifespan by learning your daily charging routine. It delays charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug. In System Settings, click Battery in the sidebar, click the information button by Battery Health, then turn on Optimized Battery Charging.
  • Low power mode: This option reduces energy usage and increases battery life. This is a good option for travel or when you’re away from a power source for an extended period of time. In System Settings, click Battery, then choose from the options in the “Low power mode” dropdown.

  • High power mode: Available on the 16-inch MacBook Pro with Apple M1 Max. When selected, your Mac allows the fans to run at higher speeds to maximize performance during intensive workloads. In System Settings, go to Battery, then choose from the options in the “High power mode” dropdown."

We hope this helps.


Take care.
