Battery Saver - Was able to find the power hogs using this app  much like Task Manager on your PC. Fancy alarm clock running in back ground: 10% cpu all the time. Associated clockface widget: another 10%. Live wallpaper 12%. Glitching file indexer (called Media Server) in continuous loop. etc. CPU now runs about 5% at idle with consequent low battery drain. Also interesting to see the feeding frenzy of housekeeping and updating when phone woken up or connected to the web. Samsung GT i9180N Galaxy s3 mini
