How To Improve Your MacBook’s Battery Life

Every time you drain and recharge your MacBook it goes through what is known as a power cycle. A typical MacBook will have an average of around 700 power cycles before it starts to experience any issues with the performance of the battery. Therefore, it is probably a good idea to do all you can to try and reduce this number to prolong the life of your MacBook and help prevent the battery from draining when you’re on the go. Here are some tips to follow if your MacBook battery is low or draining too fast.
The number one tip that goes for just about any device with a rechargeable battery is to keep your MacBook charged and plugged into a power outlet as much as possible. When you’re close to a charging outlet, perhaps sitting at your desk – plug it in, it’s as simple as that. This way you’re not letting the battery drain, helping you reduce the number of unnecessary power cycles.

But obviously, you are not always going to be near an outlet and your MacBook is a laptop after all and one of the main benefits of owning a laptop is the portability factor they provide you with. Therefore, there will be some points where you cannot plug your MacBook into the charger. Here are some tips that will help you retain power cycles and keep your battery healthy for when you are on the go.


Screen Brightness

In order to power all the individual pixels in your MacBook’s display, the battery will need to give out a significant amount of energy to do so. Screen brightness can be manually adjusted, either using the keys or touch bar on your MacBook, or the brightness slider located in Display settings within System Preferences. In here, you will also find the option to have your MacBook automatically adjust your screen brightness. This is controlled using the ambient light sensor built into your MacBook and will control the brightness of your display depending on the lighting conditions around you, brighter conditions will brighten the display etc. However, we would recommend turning this off and using the manual controls to adjust the brightness, dimming the display as much as possible in order to preserve battery life.


Multi-Tasking and CPU

In order to conserve battery you want to keep your usage simple to conserve battery, the more that you do and the more that you put your MacBook through, as far as CPU load goes, the CPU will heat up and so will the battery. Since the CPU needs to be cooled to certain temperatures, this will, in turn, activate the fans that will use even more power. A simple way to determine which apps are using up the most battery is to click the battery symbol located in your toolbar. This will then tell you which apps or internal processors are eating up most of your battery life. For those apps that you don’t need, you can simply quit and open them back up later for when you are actually going to use them. Even if you are not actively using those apps, the CPU and RAM are using power to keep them open while they run in the background. Therefore, simply closing them will help conserve power.


Use Headphones

If you are listening to music or watching a movie with your MacBook and are playing sound through your speakers, a simple but effective way to conserve power is to turn the volume down or put on some headphones. If the volume is higher than it needs to be, simply turning the volume down will help conserve power because speakers and audio devices use up quite a bit of power when on full blast. So if you don’t need the volume that loud – just turn it down.


Turn Your Keyboard’s Backlight Off

One common battery-eater is your MacBook’s backlight. This is the backlight found under your keyboard and can often take up a lot of your computer’s energy. If most of your usage comes during the day, there’s a good chance that you don’t even need one in the first place but if you do find yourself needing it, it can be adjusted manually, again, using the keys on your MacBook. However, in this case, unlike the screen brightness, we would recommend your computer doing this for you. Your MacBook can adjust this based on your surrounding lighting conditions. The way you can select this option is by heading to System Preferences and under the Keyboard menu, you can select the “Adjust keyboard in low light” option. This will help prevent your backlight from eating up power when you are not even using it.

If you want to preserve your MacBook’s battery life, the best thing you can do is keep it plugged in as much as possible. It is unfortunate but your MacBook’s battery is not going to last forever but doing your best to preserve the battery will definitely help extend your MacBook’s life span. At MacFinder, during our refurbishment testing process, the battery makes up a key part, as we aim to ensure that a customer isn’t going to receive a laptop with an overly worn battery.

However, taking active precautions now will save you money in the long run and will help your MacBook last that little bit longer.
