Habits can make or break your MacBook battery life. Whether you know it or not, certain behaviors such as extensive multitasking or using resource-hungry apps are common culprits of battery life theft. When using your MacBook, consider these as potential sources of the problem.
Battery issues are rarely due to bugs. Unless you have the newest software with the newest macOS, Apple has very few unresolved bugs. This means your problem probably stems from something else, usually usage patterns or hardware errors.
Your Battery Is Draining Faster than NormalIssue 1: Overuse (By You, or Applications)
Possible Cause: If your battery seems to be draining twice as fast, it might be because you’re using it twice as much. Especially if you recently made a major change to your workflow, such as greatly increasing how much multitasking you engage in, this could be the reason for seemingly sudden battery drainage.
How to Fix:
You can get a basic idea of which apps are draining the most power by choosing the battery icon in the top right of your Mac. This will show you which apps are currently using the most power and help you get an idea of what’s gobbling up power.
You can also cut down on the battery drain by limiting the number of programs you leave idle in the background while you work and reducing the amount of multitasking you do.
Issue 2: Using the Wrong Settings
Possible Cause: Your computer’s default settings are unnecessarily gobbling up energy while you work.
How to Fix:
Here are a few basic settings that once changed, should help reduce the amount of battery your MacBook Pro is using while you work:
Bluetooth: Always turn off Bluetooth when you aren’t using any Bluetooth accessories. Just click the Bluetooth icon located on top of the menu bar and click “Turn Bluetooth Off.”
Screen Brightness: Dimming the screen by a few degrees is both better for your eyes and the battery. https://kgixmpc.weebly.com/what-is-the-chrome-app-launcher-for-mac.html.

Keyboard Backlighting: MacBook Pros have very nicely lit keyboard, but if yours is glowing in broad daylight, you may want to consider adjusting this with the F5 function key (new MacBooks with Touch Bar is a bit different).
Energy Saver Preferences: Open System Preferences, and then choose Energy Saver. Reduce the amount of time it takes for the computer and the display to sleep to save battery.
Doing these things should help you see a considerable increase in battery life, especially if you were previously using dramatically different settings.
Your MacBook Pro Doesn’t Charge to Capacity/Doesn’t Charge At AllIssue 3: Poor Storage Methods
Possible Cause: If your MacBook goes into extended storage with full battery or no battery at all, the battery will likely suffer the consequences. Additionally, Apple notes that leaving the lithium-ion battery MacBooks with less than 20% charge for more than two days can have a similar effect.
How to Fix:
Because most MacBook Pros use lithium-ion batteries, they should be charged (or discharged) to 50% before being stored for any amount of time longer than a few days. If you’re storing your computer for several months, you should charge it to 50% every 6 months in order to avoid losing battery capacity. Other types of batteries used in older MacBook Pros also have special storage instructions, and you can find out what battery your MacBook uses here.
Issue 4: Wall Adapter is Malfunctioning
Possible Cause: It may seem simple, but sometimes the error isn’t inside your computer — instead, it’s with the wall adapter you’re trying to charge it with.

First, click on the Apple Menu in the top left. Then hold the OPTION key. You’ll see “About This Mac” change into “System Information”. Choose System Information, and then “Power” from the left-hand side.
From the Power tab, you can check the condition and cycles of your battery.
If the condition is something positive such as “fair” other “normal”, you’re good to go. But if it says “poor” or “check battery”, your battery will likely need to be replaced.
You should also compare the number of cycles to this chart from Apple that shows how many cycles your Mac’s battery will last before it begins to deteriorate. While batteries will still function after reaching this threshold, they’ll gradually work less efficiently.
If you’ve figured that you need to replace the battery, it is recommended that you go through Apple to have it replaced. The newer your MacBook Pro, the less likely you have the ability to change it out by hand.

How to Fix:
Before attempting a more complex solution, charge your Mac to 100% with the adapter and use it for two hours with the charger connected. Then unplug it and allow your MacBook’s battery to drain to 0% and the laptop to shut down by itself. Wait at least 5 hours, and power on your MacBook. The battery is now calibrated.
