Maintain Your MacBook Battery Health with Macintosh – Your Summer Guide.

MacBook battery health is most at risk during the summer. High temperatures can seriously affect battery performance and lifespan. Many users experience battery issues simply because of poor settings or improper daily use.

That’s why Macintosh brings you essential tips to help you protect and extend your MacBook battery health, especially during hot weather.

1. Adjust Energy Settings Wisely to Improve MacBook Battery Health

Your MacBook’s energy settings directly affect battery life. In the “Energy Saver” preferences, your MacBook automatically adjusts behavior when on battery.
But if you increase performance settings, your MacBook battery health may suffer. Balance is key, especially when you don’t need full performance.

2. Reduce Screen Brightness

Your display consumes a lot of power. Lower the brightness to the most comfortable level—especially in low-light environments. This simple habit helps preserve your MacBook battery health.

3. Turn Off Wi-Fi When You’re Not Using It

Even when not connected, Wi-Fi uses power. If you’re not online, disable it from the menu bar or network settings to save energy and protect your MacBook battery health.

4. Minimize App Usage and Disconnect Accessories

Close apps running in the background and unplug any external devices like USB drives or SD cards. These consume power even if not in use, and affect your MacBook battery health.

5. Charging Other Devices? Be Careful

If you’re charging your phone or another device through your MacBook, make sure your MacBook is on and plugged in.
Otherwise, the other device will drain your MacBook battery quickly—something that negatively affects MacBook battery health over time.

6. Keep Optimized Battery Charging Turned On

Apple offers a feature called Optimized Battery Charging that tracks your usage and stops charging fully when not needed.
It’s designed to protect MacBook battery health by reducing stress on battery cells.

7. Stick to 40%–80% Charging Range

Lithium batteries last longer when charged between 40% and 80%. Charging to 100% regularly or letting it drop too low puts stress on the battery.
Maintaining this mid-range is ideal for preserving MacBook battery health.

8. Don’t Keep Your MacBook Plugged in All the Time

Even if your MacBook seems fine, keeping it plugged in constantly can shorten battery life.
Once charged, unplug it and let the battery drop a bit before charging again.
And if you’re storing it for a while, charge to 50% every six months to support MacBook battery health.
