Why does the Samsung S60 draw so much power?
Most of the power consumed on a mobile device is by the display. I'm not sure how you are getting these current measurements, but 100mAh is good. 1 amp seems high if you're not running an app. I found by uninstalling apps like Snapchat and Facebook I was able to get extra battery life. Companies like Symantec publish annual reports of apps that consume extra battery and network data. Check those out.
