Enabling battery percentage is standard fare if you’re using a handset made by Samsung, LG, Motorola or HTC. All you need to do is head into your phone’s settings and toggle an option to display the percentage in the battery icon. Here’s how to add a more exact percentage to that icon.
You can always see the percentage of your battery by dragging down on the notification bar twice, but that doesn’t exactly give you “at a glance” monitoring. You can enable always-on battery percentage in Android 6.0 Marshmallow with a somewhat hidden setting, and in 4.4 KitKat and 5.0 Lollipop with a very hidden setting.
How to Show Your Battery’s Percentage in Android Marshmallow
To turn this feature on in Marshmallow, you’ll need to enable Marshmallow’s “System UI Tuner”, which gives you access to some hidden settings.
How to Show Your Battery’s Percentage in Android KitKat and Lollipop
KitKat and Lollipop actually have this feature built-in, but the setting is even more hidden. In fact, the setting doesn’t exist at all! The only way to disable it is with a few ADB commands, or the Battery Percent Enabler app from the Google Play Store. You don’t need to be rooted or anything to use this, so most KitKat and Lollipop phones should find this works with the below instructions.
1 Open the Google Play Store on your phone (or head to the Google Play Store in your computer’s browser) and search for Battery Percent Enabler. Select the app from “kroegerama” (there are a few apps with the same name).
2 Once installed, click the “Open” button that appears (or navigate to the app in your app drawer).
3 Check the “Enable Battery Percent” box and reboot your phone.
4 After rebooting your phone, you should find that Android’s battery icon shows how much of a charge it has.
