Battery Issues With Your Macbook? Check Your Power Wattage




Your Macbook won’t keep it’s charge while you’re using it.

It may charge up overnight, but it can’t keep up during the day.

You likely run a lot of processes whilst using your mac, including, but not limited to:

  • Multiple Chrome & Brave instances
  • Microservices
  • VS Code
  • Docker
  • Kubernetes
  • Spotify
  • iTerm2
  • Trello
  • Discord
  • Postman
  • Postgres
  • MySQL
  • SQS
  • ToDo
  • Skype (don’t ask)
  • Whatsapp Desktop
  • … & some others from time to time.

Alas, your Macbook doesn’t want to play nice anymore.



  1. Coconut. A neat little app that runs diagnostics checks on your battery, it’s completely free and gives a good insight to the state of the internal battery in a mac.
  2. Check your Macbook power supply. In the case of a work Macbook, you may have ended up with the wrong power supply for your Macbook. If this is the case, you’ve reached a point where your Macbook needs more juice from the power than it can physically get.

To find your expected Mac wattage go to Apple -> System Preferences -> System Report -> Power and look at the AC Charger Information
