With the whole iPhone slowdown fiasco, battery health is more important than ever. While this does not necessarily apply to Android phones, it is always a good idea to keep your device’s battery health in mind.
On Android, however, there is no easy or built-in way to check your battery health. It’s a glaring omission on Google’s part, but one that can be remedied with a third-party app. While there are several options for doing so, we recently discovered an app called AccuBattery that performs better than any other we’ve tried.
But, before we get into how to use the app, let’s be clear: you’ll have to play the long game on this one. Because Android doesn’t have a built-in way to track battery health, any app that does so will have to monitor your battery for days, weeks, or months before determining its health. AccuBattery begins to get a sense of your device’s battery health after a few charge cycles, but the more you use it, the more precise it becomes.
First and foremost, download and install AccuBattery.
You’ll be taken through a fast walkthrough of what it does and how it works as soon as you turn it on. It’s worth noting that this app does a lot more than just check your battery health, though that’s what we’re interested in.
During the walkthrough, you’ll come across a page about battery health—pay close attention to this because it’s the foundation of what we’re looking about here.
You can also set a slider on the following page to notify you when your battery reaches a certain percentage. The default setting is 80%, which is widely considered to be the best setting for keeping your battery charged for health and longevity. However, you should make whatever decision works best for you; for example, I left mine at 100% because I use Android Auto and was tired of it continuously alarming when I couldn’t unplug it without ruining my Auto connection.
Finally, AccuBattery performs a fast calibration and determines the capacity of your device’s stock battery.
And that’s it!
Note: AccuBattery comes in free and Pro ($3.99) versions, but you won’t need the Premium edition to keep track of your battery’s wellbeing. If you like this feature, I recommend upgrading to the Premium version to help support the continued development of this fantastic app. The Premium version eliminates advertisements and allows you to open an overlay on top of other apps to check battery and CPU stats.
Simply use your device as usual from here on out. Charge when you’d normally and use when you’d normally. Just keep doing what you’ve always done. AccuBattery keeps track of your charge and discharge cycles over time and uses that data to monitor your battery’s health.
To see this data, go to the bottom of the screen and tap the “Health” option. Initially, it only displays blanks. That’s because it doesn’t have any data to go on right now. Because Android doesn’t provide apps with historical battery data, they have to build from zero.
