Adds a configurable Energy Bar at the top of your screen indicating current Battery level. And just when you think such a simple battery bar can display such a crucial information try plugging in your charger - you'll be amazed by the details of the animation you'll see. The pulsating animation and the bar together not only indicates the current Battery level but also how much has the Battery charged since you plugged in your charger.

There is something about visual over numbers that keeps you and your device's battery level in sync with just a glance. You may find it intuitive/effective/stylish way to read the battery level.

Out of the box features:-

✓ Adjust the thickness of the of the bar all the way from 1 pixel to a value of 21.
✓ The Bar can be aligned left / center / right of the screen just in case you prefer reading things from left to right. ;)
✓ You can color code your Energy Bar to add an extra layer of information. A good instance could be you can split the bar into segments of 4 starting from 1% you can have a different color at each 25% of the battery.
✓ You can auto hide Energy Bar on fullscreen content (Apps Movies Images Games etc.)
✓ The process of splitting the Bar is facilitated by an intuitive UI where you can drag the sliders back and drop it at a point where you want to make the split.

Want to delete a segment? Just drag the slider of a particular segment to it's minimum value and it will automatically get deleted.

Created lots of segments? Want to delete all? No Problem! Just drag the slider of the first segment to it's minimum value and everything gets reset.
✓ Three types of color pickers to choose any color in the world. You can either play around with the pickers to see what you like or just be precise with HEX codes.

Pickers:
HSV color picker
RGB color picker
HEX code color picker

Apart from the core features mentioned above the app has a 'Support Dev Pack' which you can get as an in-app purchase to support me (the developer) as well as get some uber cool extra features:

Status Bar:
✓ If you are on Android 4.4+ you can set Energy Bar as your status Bar. And just in case your status bar hides Energy Bar on some screens the Bar's thickness by default is a pixel or two more and so you'll see a really thin Energy Bar below your status bar on some screens.

Gradient Bar:
✓ I personally love this feature while you can already color code Energy Bar out of the box with segments this feature let you set a gradient to the Bar making the Bar fun to look at all the time yet delivering crucial information about your battery ;)

Merge Segments:
✓ If you have created multiple segments you can merge and show at once. It's like gradient except that colors have sharp boundaries.

All that is cool! But what about Energy Bar consuming Battery?!

This is one of the most exciting question for me to answer. Energy Bar more than anything understands that you need to utilize your battery efficiently (after all that's why you installed the App right? ;) .) Energy Bar sits on the screen silently putting almost 0% load on CPU if battery level changes Android wakes up Energy Bar. Once awake Energy Bar quickly updates itself and goes back to sleep. And to be that extra efficient the Bar 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.

Accessibility Service's permission requirement: Users have been enjoying the ultra stability and reliability of Energy Bar every since version 5.0. And that's because it now runs as an Accessibility Service. The permission prompted by Android when Energy Bar is turned on is a 'minimum requirement' for ANY Accessibility Service (even a dummy one.) Be assured that the App does NOT access anything.
