Is it safe to leave your MacBook plugged in all the time? In this video, I break down what actually affects Mac battery health, whether constant charging is bad, how Apple’s new Charge Limit feature works in macOS Tahoe 26.4, and whether fast charging really causes meaningful long-term damage.
I also go over Optimized Battery Charging, battery health, slow charger alerts, heat, charging myths, and the best settings to help your MacBook battery last longer.
If you use your MacBook docked at a desk, plugged into a Studio Display, or fast charge with Apple’s higher wattage adapters, this should help clear up a lot of the confusion.
Let me know in the comments how old your Mac is and what your battery health percentage is right now.
