Hey,
If you have a MacBook Air or MacBook Pro it will come with a battery. Battery life degrades over the life time of the battery. Although there isn’t much you can really do about it, other than trying not to cycle the battery too many times, you can keep an eye on it’s health. This allows you to buy a new one, or get it replaced at an Apple shop before there is so little charge left that always needs to be tethered to the wall. This post is going to show you a couple of methods to ensure you know how healthy your MacBook is running at.
Finding The Health
To find the health of your battery open up System Information in Applications > Utilities. Within the sidebar select Power from the Hardware section. This page will list all of the related bits of information regarding the power supply to your MacBook.
There are two pieces of information that are of use, the charge remaining and the condition. If you have a fully charged battery the charge remaining in milli ampere-hour should be similar to the full charged capacity from fresh which is about 6000 mAh. If your laptop battery is starting to degrade this value will slowly never reach the fully charged battery value.
The second piece of information worth looking at is the condition parameter. There are three settings, Normal, Replace Soon and Replace Now. If the latter two options are appearing it may be time to replace the battery in your laptop. Apple has a guide on how to replace the battery in your laptop.
Apps
There are other ways of getting the battery power of your Mac. One of the apps I recommend if iStat Menus. These have some of the most well designed menus which allows you to see a multitude of information. One of these is the battery life.
If you want a free app, a popular app is Battery Health, this gives you the health of your battery in an easy to read format, plus it is free which is always good.
Conclusion
Battery life is important to your Mac. Keeping an eye on it isn’t that complicated, with a couple of free apps and a little bit of know how you can keep an eye on your battery life.
