MacBook battery draining too fast: Here’s the best fixes for Mac battery problems
First thing you need to do is check your power settings to see if your battery is being affected. In the control panel look at the power management settings. Switch the power saver on and see if that helps.

If that doesn’t work, it could be that you have a hardware failure or a hardware problem. You should back up your Mac, but then you could try reinstalling OS X.
If they all don’t work, you may consider taking your MacBook to a service center and talk to a technician. It may be a hardware issue such as a bad battery or a bad charging port or bad charging cable.
Checking battery health is an important option in the OS X power management setting. The OS ensures that sensors in the battery will be regularly connected to your Mac. They will also provide power status information, so your battery is always in a healthy state. When the battery has reached a certain level, battery percentage will appear on the OS X notification bar, showing the remaining capacity of the battery.
To see the battery health at any point, you can use the menu bar tool: System Information > Battery Health.
Determining battery health is not a one-time process, so you may need to check the battery regularly. It is particularly important if you have a notebook battery, because the life of the battery is particularly related to your computer’s physical condition. It’s a good idea to recalculate battery health every 6 months to check if it is trending upward or downward. But for MacBook users, the battery health is most important in the middle to end of the cycle.
But it does not automatically update to the real time. It is best to re-check the batteries periodically and in some cases, rather than operating conditions, if the battery appears to be declining.

The battery aging process, which affects the battery capacity, is a natural phenomenon.
