I don't know what happen to the attachment screenshot. The last I check what's using the most battery power - Google Googles was using 79%. I uninstall and battery drain return to normal. If the app work for you.. that's good. You can check your battery consumption by doing this...... not really sure how an app that opens and closes when you ask it to can drain your battery. Just use it when you have to, and make sure you press the back button when you're finished, not the home button. It closes.
I've used a few times here and there, it's never affected me at all.

Menu - settings - about phone - battery - battery use to see what's using the most battery. Android system should be on top.
I've never heard of android system consuming more battery then the display. If your android system is on top, you've got some problems. My android system has never went above like 5%.
