Carrying a laptop charger everywhere you go can be tiresome and when you do, one is constantly looking for a socket. So what can you do to fix your battery-draining problem? 

Here are some simple tips to boost your MacBook’s battery life:

  1. Regularly check your Battery’s health– you can do this by clicking the CleanMyMac app that you’ll find on your Mac menu taskbar. By doing this, you’ll be able to see the overview of your Mac’s battery life. 
  2. Monitor your screen’s brightness– The system’s display is one of the major components that feed off your battery. The best cause of action is to reduce the brightness so as not to burn a lot of your battery’s life. 
  3. Investigate what could be draining your battery– It is always useful to know what could be using that amount of energy on your laptop. This could be accomplished by going to your setting and checking on the utilities. This way you can see all your applications and monitor their activities. 
  4. Unplug some of your peripheral devices– Apart from your internet connections you can also monitor all the devices that might be connected to your computer. In this case, if you have many devices connected to your device then it’s a probability that it’s causing your battery to drain fast. 
  5. Upgrade to the latest macOS– It’s advisable to keep your MacBook with the latest version. This way, if there is an issue that is about to affect your battery, then the problem itself would have been fixed. 
  6. Energy Saver– This is an inbuilt feature available for the MacBook. So if and when you turn on this feature be assured that your battery backup will be improved. 
  7. Turn off the keyboard light– If you want to save your battery especially when you are not close to a socket be sure to turn off the light on your keyboard. This will reduce the amount of energy that will be used by your battery to a great extent. 

All these tips recommended above will be sure to put you at ease whenever you are too lazy to carry a charger, or that there may be a power outage, or that there could be no power socket anywhere close to you. As a reminder, if your battery continues to act up, be sure to replace it.
