Laptop batteries are getting better. The Lenovo Carbon X1 and HP EliteBook x360 can get to 16 hours and the Carbon X1 can charge to 80 per cent within an hour. Apple MacBooks quote ‘all day battery’ BUT these laptops are not cheap. For your average Laptop though you’ll be lucky to get just a few hours, so you need to manipulate the settings.

The display is, for the most part, the biggest drain on your battery. If you want to be specific, it’s actually powering the backlight which illuminates the pixels on your display that drains the battery. In which case, it would seem obvious that the best way to prolong your battery life is to simply lower the brightness on your display. You can usually do this using your keyboard on Windows 10 laptops and Apple Macbooks, but there are other ways you can do this to automate it.

Changing Display Settings

Windows 10

XPS 15 Touch Notebook

HP Spectre Pro

For Windows 10 laptops you need to go to the Control Panel, choose the Hardware and Sound, then Power options and select Power Saver or Balanced. You should only really use the High Performance plan when you need a boost for high-end graphics apps or gaming. With Windows 10 there are more power and display settings available from the Setting button on the Windows 10 start screen. From the left-hand edge select the Home and Settings options, then tap System. If you choose Display you will find a slider which you can use to adjust the brightness level.

You can then also use the same menu to select Battery Saver and toggle it to the on position. You may find that the toggle button is grayed out, if so just unplug your laptop so that it’s running from batter power and the toggle button will become active. The Batter Saver feature is new to Windows 10 and limits push notification and background activity in order to extend battery life.

The last thing you can do is tap the Power and Sleep from the left-hand menu, then select times for the screen to be turned off and put into sleep mode when your laptop is on but not being used, which will save any unnecessary battery usage.

Mac OS X


MacBook Pro

On the Apple Mac OS X system you need to open System Preferences and then click on Display. The Display tab will have a slider button where you can adjust the brightness levels. You should lower it to a point where it’s not eye-achingly dull. A lower level of brightness also helps to protect your eyes, unless you’re sitting in bright sunlight in which case you will need to set the brightness at its highest level so you can see clearly.

You’ll see a check box below the slider which allows your Mac to automatically adjust the brightness. However you may find that manually setting it according to the environment you’re working in will actually be more effective at saving the battery life. You can also set the ‘slightly dim while on battery power’ option in the Energy Saver area of System Preferences. Also on the Energy Saver page, you can set times for Computer Sleep and Display Sleep. These will kick in when your MacBook has been idle for a period of time which you set yourself.

Keyboard Backlighting too

Keyboard backlighting is also another drain on your battery life. This setting varies by manufacturer on the Windows 10 versions but if you’re using OS X you can find it in System Preferences and then Keyboard.


Don’t forget

Whilst the display is the biggest culprit when it comes to battery draining, you can still use the basic options of ensuring your WIFI and Bluetooth are switched off when you’re not using them and unplugging any peripherals that aren’t being used.
