Get the best battery life for your MacBook by changing these settings

Here are some things you can try to help your battery out both today and for the long haul.

MacBooks are quite good at managing their own power consumption. But there may be fringe cases where you want to take matters into your own hands. If that's you, here's how to squeeze the most out of your MacBook's battery life.

Before fiddling with settings, it's a good idea to check the baseline you're working with. Go to System Settings > Battery , and see what it says next to Battery Health . Click the "i" icon next to that to see it as a percentage of its original capacity. If it's 100 percent, then your battery's age isn't affecting its current maximum. (And if it's something like 95 or 90 percent, there isn't yet much to worry about.)

Apple recommends replacing a MacBook's battery if the percentage is below 80 percent. (In fact, you'll see a service warning.) If yours falls that low, then it's time to book a Genius Bar appointment.

To get the most out of the battery in the long run, you can optimize your device's charging. In System Settings > Battery , click the "i" next to Charging , and then choose Optimize Battery Charging . This caps your Mac's charge at 80 percent. That won't change your battery life right now, but it may extend its lifespan.

The menu bar's Battery shortcut is an ideal place to monitor things. Clicking on it will reveal not only the battery's charge, but also its current Energy Mode and any apps using a lot of power. This is also a handy place to override the 80 percent cap when you need a full charge — say, before a long flight. And if you don't see the Battery icon, go to System Settings > Menu Bar , and make sure there's a checkmark next to Battery.

If you had to pick one setting to extend your MacBook's battery life, Apple's Low Power Mode is it. Head to System Settings > Battery , and check the settings under Energy Mode . Chances are, it's already set to Automatic, which is the best option for most people.

If your MacBook has an aged battery — or you just need to stretch things out for a long day — you can switch Energy Mode in the On battery section to Low Power . This leaves it in energy-saving mode even when it has a good charge. And if this setting somehow got changed to High Power on battery, then, well, there's the source of your problem.
