Battery percentage is used by users to charge the device based on the percentage(if the charge <25 % then charge the device till 100% and if not less then 25 % then do not charge in order to extend your battery life)

The below steps are common for all the Android devices with version greater then Android 4.1(jelly bean) to the present Android 4.4 (KitKat) only with some minor modifications.

You can simply uncheck the Show Battery Percentage in the Settings.

Go  to the settings>Battery.

![Step 1 Settings>Battery][1]

In that you can see that the Show battery Percentage is checked. You can simply uncheck that and the battery percentage will not be displayed.

If at all the check box is not under the battery menu then you might be having it under the Display menu.

Last but not the least please check if your device is available for the Update to Android 4.4.4 if yes then go ahead with the update.
