The standard battery icon on your Android can be a little misleading. The icons for 90% and 80% battery may look the same, just like 15% and 5%. If you want a more detailed meter for your device's charge, check out ChargeBar for Android. This app puts a small bar along top or bottom of your screen that indicates the percentage charge of your device. It's easy to use and customize, read on to learn about it.
Step 1: Download and install ChargeBarChargeBar - MIUI Battery Bar.
Step 2: Run the app and examine the configurable options.
While the default settings are sufficient, you might consider changing the bar color, size, and enabling startup on boot. The actual indicator bar can be placed at the top of the notification shade, as a separator between the notification shade and the rest or the screen, or at the very bottom of the screen. You can also adjust whether the bar shows on the lockscreen, or while you're using full-screen apps.
Step 3: Press the large ChargeBar icon at the top of the app to enable the bar.
Despite this bar not including an actual battery percentage number, it is definitely more accurate than looking at a small battery icon with only four to five different phases. How do you check your battery percentage?
