Battery life is the amount of time your device runs before it needs to be recharged and the Battery lifespan is the amount of time your battery lasts until it needs to be replaced. Maximise both and you’ll get the most out of your Apple MacBook Air or MacBook Pro.
Update to the latest software - Always make sure your MacBook is using the latest version of macOS. If you’re connected to the Internet, macOS automatically checks for software updates every week, but you still control when the updates are installed. To confirm that you’re using the latest software, go to the Apple menu and choose Software Update.
Use Energy Saver – The Energy Saver pane includes several settings that determine power levels for your MacBook. Your MacBook knows when it’s plugged in and runs accordingly. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximise performance, your battery will drain more quickly.
Lower the brightness of the screen - Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a video on an aeroplane, you may not need full brightness if the cabin lights are off.
Turn off Wi-Fi when not in use - Wi-Fi consumes power, even if you are not using it to connect to a network. You can turn it off in the Wi-Fi status menu in the menu bar or in Network preferences.
Applications and peripherals - Disconnect peripherals and quit applications not in use. Eject an SD card if you’re not currently accessing it.
Plug in and power on your MacBook to charge other devices - Make sure your MacBook is plugged in and powered on when you’re using it to charge other devices via USB. Otherwise those devices may drain the battery in your MacBook faster than normal. If another device is connected to your MacBook when it’s turned off or in sleep or standby mode, the device’s battery may drain.
Avoid extreme ambient temperatures - Your device is designed to perform well in a wide range of ambient temperatures, with 16° to 22° C (62° to 72° F) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won’t power your device as long on a given charge.
Charging the device in high ambient temperatures can damage it further. Software may limit charging above 80% when the recommended battery temperatures are exceeded. Even storing a battery in a hot environment can damage it irreversibly.
When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range, its performance will return to normal as well.
MacBook works best at 10° to 35° C (50° to 95° F) ambient temperatures. Storage temperature: -20° to 45° C (-4° to 113° F).
Store it half-charged when you store it long term - If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:
Do not fully charge or fully discharge your device’s battery — charge it to around 50 per cent. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.
Power down the device to avoid additional battery use.
Place your device in a cool, moisture-free environment that’s less than 32° C (90° F).
If you plan to store your device for longer than six months, charge it to 50 per cent every six months.
Depending on how long you store your device, it may be in a low-battery state when you remove it from long-term storage. After it’s removed from storage, it may require 20 minutes of charging with the original adapter before you can use it.
