Different Mac batteries have different maximum cycle counts , from 1000 for a Macbook Pro Retina to 300 for the first Macbook Air. Once the cycle count is reached, your Mac battery should be replaced.

Turn off Wi-Fi and Bluetooth
People tend to connect MacBook to Wi-Fi network all the time and don’t have the habit of turning it off when we are not connected to a Wi-Fi network. This consumes a lot of power to support its function, because it will hunt around for Wi-Fi networks it could join. Therefore, when you are not using Wi-Fi network, closing it is also a great idea to improve battery life on MacBook Pro and MacBook Air. And if you’re not using external wireless peripherals that communicate via Bluetooth — some keyboards, nice, speaker systems and other peripherals — then please turn it off. Because both AirPort and Bluetooth can consume significant amounts of power.
To disconnect Wi-Fi:
– Click on the Wi-Fi symbol on the top bar
– Click the Turn Wi-Fi Off option
To disconnect Bluetooth:
– Go to System Preferences > Bluetooth
– Click the Turn Bluetooth Off button,
Use Energy Saver
As the official said, you can set options conservatively on Energy Saver Pane when your MacBook is on battery power. In this way, you can save MacBook battery life and use computer longer when it is unplugged to an AC power.
You can go to System Preferences > Energy Saver and click on Restore Defaults to make sure you are using these settings. You can also further customize them to your liking, and schedule when your Mac will sleep and wake.
Use Software Update
Apple routinely offers patches and enhancements to Mac OS X and macOS Sierra that improve battery life.
