Have you searched all over your Android phone's settings without finding a way to enable the battery percentage? Because each hardware maker's version of Android differs, some phones may enable this feature by default, while stock Android does not allow it at all.
If you've rooted your device, this is a simple fix using Xposed or a custom ROM. However, there is a simple tweak without rooting you can perform on any device running KitKat (4.4) or above.
Head to the Google Play Store and download Battery Percent Enabler. Run the app, read its short explanation if you like, and then simply check the box and reboot your device. Now you'll have your phone's exact battery percentage displayed inside the battery icon!
On KitKat, you'll notice that you can't see the battery percentage unless it's below 40% or so because of a head-scratcher of a UX decision; someone made the text color identical to the battery fill color. The app's developer can't fix this because it's hard-coded into a system file, which would require root access. On Lollipop (5.x), they adjusted this and you can see the battery percentage starting at 99%.
Once you've rebooted, feel free to remove the app from your phone. You don't need it unless you want to remove the percentage, in which case you'll need to reinstall, uncheck the box, and then reboot again.
Now that you can monitor it, be sure you're maximizing your battery life!
