Adds a configurable Energy Ring around the camera lens indicating current Battery level. Dive into the various configuration options, not only you can quickly glance and get the battery info but, Energy Ring adds an accent to your phone's camera lens.
Got a full charge? The Ring will be a 360 degree wrap around the front camera lens.
Battery depleting? So will the arc of Energy Ring.
All that is cool! But what about Energy Ring consuming Battery?!
This is one of the most exciting question for me to answer. Energy Ring more than anything understands that you need to utilize your battery efficiently (after all, that's why you installed the App, right? ;) .) Energy Ring sits on the screen silently putting almost 0% load on CPU, if battery level changes, Android wakes up Energy Ring. Once awake, Energy Ring quickly updates itself and goes back to sleep. And to be that extra efficient, the Ring goes on deep sleep when you turn off the screen, meaning it doesn't even read changes in battery level when the screen is off.
Android requires Energy Ring to run as an Accessibility Service, to be able to display on Lock Screen. It does not read/monitor any data, whatsoever. This is especially useful for people who have disability to read numbers and work better with visual data.

The original variant of the App, Energy Bar has been used over several years by users on their AMOLED devices, there has been no complains. But there is no claim that it may not happen.
If you enter into power saving mode, Energy Ring will be disabled by the System, to re-activate you must restart your device.
