Battery life is limited like any other battery. Laptops can consume large amounts of power and as a result, your laptop battery can suffer from a shorter life due to being fatigued by your laptop activities which may require replacing sooner than its expected life. You can take steps to extend the life of your battery as well as help it conserve power while it’s not charging.
Disconnect the devices from the laptop. Any device connected to the laptop, such as a USB device or other display device via VGA, will require CPU activity to access these devices. Some USB devices require a lot of power causing the battery to drain faster, such as a fan with moving devices. Unplug any devices you don’t need to use.
Turn off or activate sleep mode on your laptop when it is not in use. If you need to leave your laptop turned off for long periods off the charger, put the laptop to sleep to leave your operating system in its current state and it will resume from that point on. Turning off the laptop will require a boot sequence that may consume additional power. You can close the lid, press the sleep button on your laptop to put your system to sleep, or press the power button to let your laptop go through shutdown sequences.
Activate the power saver options in your operating system. Your operating system will modify hardware and software behavior which reduces their activities and uses less power than your laptop. Power options can change the behavior on a laptop such as a CPU or a hard drive to become active only when certain actions are needed.
Otherwise, your device becomes inactive after a short period to conserve power. On Windows laptops, you can change the power plans in the Control Panel. Search for and locate “Power Options” in your version of Windows. You can change between available plans or customize advanced settings designed to
macOS laptops, click Apple > System Preferences > Energy Saver to bring up the Energy Saver window. You will be able to adjust screen brightness settings and indicate when your laptop sleeps or turns off.
Turn off the wireless and Bluetooth settings. The laptop always looks for a connection when the wireless and Bluetooth functions are active. When working away from Bluetooth devices or areas with a network connection, disabling these features will stop your laptop from looking for devices to connect to. Disabling these settings will vary depending on your operating system.
In Windows, go to Devices and Printers in Control Panel. Right-click on the Bluetooth-enabled device you want to change and click on Properties. Click on the Services tab and uncheck the Bluetooth device you want to disable, then click OK.
On macOS, select the menu bar and click on the Bluetooth status icon and choose “Turn off Bluetooth”.
Turn down the volume and brightness. A brighter picture or louder sound will draw more power from your laptop. These settings vary depending on your operating system.
In Windows, you can adjust the volume by clicking the speaker icon in the taskbar and either moving the volume down or clicking the mute icon to stop the sound. To adjust brightness, go to Power Options in Control Panel and adjust the slider at the bottom of the window to change the brightness setting.
On macOS, you can adjust the output volume and screen brightness under System Preferences. To adjust the sound, click the sound icon and adjust the output volume slider to change the volume, or click Mute to mute the sound.  To change the screen brightness, click on “Display” and then click on “Display”. Change the brightness slider to adjust the screen brightness.
Keep your portable computer and Its battery in dry and cool, temperatures. Keep the laptop in a well-ventilated area while resting on a hard surface to increase airflow to the laptop. If you’re working on your laptop in a bed or on a carpeted floor, consider using a small tray to put it on.
Avoid activities that cause high temperatures. Your laptop battery may experience higher levels of heat due to your laptop if you experience persistently high CPU, graphics card, or hard drive activity. Running a single high-activity program like a video game or running several low-power programs will help keep your laptop active.
Running a graphically intensive video game or even watching a movie from a DVD or Blu-Ray will require more power from the CPU, graphics hardware, and hard disk and generate more heat.
You may need to refer to your laptop’s user guide or the manufacturer’s website for information on how to remove the battery if you are not able to remove the battery.
Remove the battery from the laptop when powered by the AC adapter. If your laptop is primarily powered by the AC adapter, a fully charged battery holds more power which will wear it out faster. To remove the battery, locate the battery on the laptop and open the clips holding the battery. There may be one or two clips that can be moved to their opposite ends to allow you to pull the battery out.
Some MacBook laptops have built-in batteries that cannot be removed normally.
If the battery is unable to hold a charge for the intended charging cycle even after the battery has been charged to its maximum level and left outside the AC adapter, the battery may need to be replaced.
Leave the battery charged midway whilst it isn’t needed. Leave the battery charged at 20-80% if you plan not to use it for more than six months or your laptop will be left on an AC adapter for power for extended periods.  Allow the battery to fully charge in the laptop. Remove the AC adapter until the battery capacity is discharged halfway. Turn off the computer and out the battery.
A battery charged halfway uses less energy allowing it to have a longer life.
If you need to use the battery, replace it with your laptop with the AC adapter plugged in and let it charge up to 100%. Once charging is complete, you can remove the AC adapter to allow the laptop to run on battery power.
