Your battery has to take in more power which eventually will result in draining your battery’s life. Also, unknowingly if your Bluetooth is on, then it might lead to a reduction in the capacity too. These are the basic settings that you have to change to keep your battery alive.

If you’re not using your MacBook for a long time, then it is likely that your battery will lose its power. To keep the Macbook battery life in good condition, you should use it frequently. If you don’t use it, you should charge it once in a while to keep it functioning.

We all do this. For easy access, we keep open all the tabs even when it’s of no use. This way, we will have several applications running in the background. More battery is required to run these applications, which results in a reduced capacity. So ensure you keep one tab opened then multiple tabs while working.

4. Fault In Your Charger

If your charger is damaged, your laptop will not charge to 100% like usual or not charge at all. So, you need to check if it’s working fine too.
