Hands down. Amazing App! I was having major battery drain issues. Using OS monitor  I was able to narrow it down to Google Play Services. I turned off sync location and all of a sudden CPU usage dropped to nothing. Upon restarting location services  CPU usage stayed low. But once I re-enabled sync I saw CPU usage jump back up to ~20%. That's when I knew where my issue was. I would have been lost without this app!
