How To Monitor MacBook Battery Health?

Whether you have a MacBook Pro or a MacBook Air, you will probably say that one of the most important things that you love about your MacBook is the easy portability and long battery life, allowing you to work on your MacBook while on the go; while at the park, while on a flight or pretty much anywhere you want to, even if there’s no wall socket in sight.

That being said, your MacBook’s battery health is critical in deciding how enjoyably you experience your MacBook’s portability. Below, you can learn about a great app that lets you carry out a MacBook battery health check, an app that can also help you carry out a few innovative diagnostics with your Mac’s battery.

Battery Diag

Battery Diag, released by Rocky Sand Studio, recently came into the spotlight for Mac owners after it was announced that it was one of the “Best New Apps” at the Apple app store.

Main features of Battery Diag

  • Compatible with OS X 10.9 or higher
  • Single click on Utility’s Menu-bar Icon brings up the app
  • Different themes available, to let you choose one that best matches your desktop
  • Displays important information, as mentioned below
    • Battery Capacity %*
    • Battery Capacity in mAh
    • Current Charged %
    • Current Charged in mAh
    • Power Source
    • Health
    • Cycle Count
    • Unplugged Time Remaining
    • Power Usage
    • Battery Temperature

* If you have an older MacBook Pro or a MacBook Air, chances are that your battery will never be able to fully charge to 100%. Over time, battery capacity tends to deteriorate and it is not uncommon for MacBook’s to only be able to charge to 85% to 90% of the capacity levels that you enjoyed when you first brought your MacBook home.

What we really like about the app is the fresh and very easy-on-the-eye flow of the user interface. Actually, your OS X’s native utilities has a battery diagnostic tool that can give you all the information that this app displays although you will have to dig it out from several layers of menus if you want to access it, not ideal when you quickly want to check how your battery is doing. Moreover, the default OS X battery diagnostic app is nowhere as effective as Battery Diag when it comes to quality of user interface.

How Battery Diag can be of use to you?

While most of the stats that Battery Diag can give you are fairly obvious and not very intuitive in nature, there are a couple of stats that can help you diagnose problems with your MacBook’s battery.

Battery Temperature – Ideally, you want your MacBook’s battery to be about 30.6 C’ or about 87.0 F’. If the app shows that your battery is much hotter than these figures, it makes a lot of sense to identify why the battery is hot, as battery temperature really affects battery performance.

Power Usage – If you are a power user and are disappointed with your MacBook’s battery performance, we would suggest that you try monitoring the “Current Power Usage” stat, displayed in Watts. You will notice that power consumption is not always the same. As an example, when you are running some heavy duty video editing, power usage can go up to as much 40+ Watts, causing your battery to drain pretty quickly.

Full Capacity – As briefly mentioned earlier, your MacBook’ battery’s full capacity might have deteriorated over time. While it might have been capable of giving you 8.460 mAh of battery life when you first bought it, it might now be capable of giving you only 7,700 mAh of battery life, about a 91% maximum level when compared to the 100% when you first brought it home. When the Full Capacity/Design Capacity dips to less than 80% levels, it might be a good time to invest in a new battery for your MacBook.
