How to Extend the Life of Your Apple MacBook Battery
Your MacBook’s battery is one of its most important components, and with proper care, you can maximize its lifespan and performance. Over time, batteries degrade naturally, but by following the right practices, you can extend your MacBook’s battery life and delay the need for a costly replacement.
At My Byte, we specialize in MacBook battery replacements and diagnostics, but before you get to that point, here are some expert tips to help you keep your battery healthy for as long as possible.
1. Avoid Keeping Your MacBook Plugged In All the Time
Many users make the mistake of keeping their MacBook constantly plugged in, thinking it will preserve battery life. However, staying at 100% charge for long periods can degrade the battery over time.
What to do instead:
• Let the battery cycle between 20% and 80% for optimal longevity.
• If you’re using your MacBook as a desktop replacement, unplug it occasionally and let the battery drain slightly before recharging.
• Enable Optimized Battery Charging (found in System Settings > Battery) to prevent overcharging.
2. Use the Right Charger & Avoid Cheap Alternatives
Using a non-genuine charger can damage your MacBook battery and lead to overheating or inconsistent charging.
Best practices:
• Always use an Apple-certified charger and USB-C cable.
• If you need a replacement, check that it meets Apple’s wattage recommendations for your model.
• Avoid third-party chargers that don’t have MFi (Made for iPhone) or Apple certification.
3. Keep Your MacBook Cool
Excessive heat is the biggest enemy of lithium-ion batteries. If your MacBook gets too hot, it can permanently degrade the battery cells.
How to prevent overheating:
• Avoid using your MacBook on soft surfaces like beds or couches, which block airflow.
• Keep your macOS and apps updated, as outdated software can cause unnecessary CPU usage and overheating.
• If your MacBook runs hot frequently, clean out dust from the vents and consider a cooling pad.
4. Reduce Background Processes & Brightness
Many background apps drain battery life without you realizing it. Reducing unnecessary usage can significantly extend battery health.
Tips to optimize battery usage:
• Open Activity Monitor (Finder > Applications > Utilities) to see which apps are using the most energy.
• Close unused apps and disable background processes that consume power.
• Reduce screen brightness to around 50% when possible.
• Use Safari instead of Chrome, as Chrome is known to drain MacBook batteries faster.
5. Enable Energy Saver Mode
macOS includes built-in battery optimization features that help extend battery life.
How to enable it:
• Go to System Settings > Battery > Low Power Mode and turn it on when running on battery power.
• This mode reduces background activity, lowers CPU performance slightly, and extends battery life without major performance loss.
6. Avoid Deep Battery Drains
Letting your MacBook fully drain to 0% frequently can damage the battery cells over time.
Best practice:
• Charge it when the battery level hits 20-30% instead of letting it drop to 0%.
• If you need to store your MacBook for a long time, charge it to 50% before turning it off.
7. Monitor Your Battery Health
Checking your MacBook’s battery health regularly can help you determine when it’s time for a replacement.
How to check:
• Click the Apple Menu > System Settings > Battery and look for the Battery Health percentage.
• If the status says “Service Recommended,” it may be time for a battery replacement.
