This has been happening over the past two days, ever since I installed PureCal widget with no success of running it properly. I uninstalled it today. However, the battery drains really quickly and the phone heats up a bit. The battery usage since my last restart (28 mins ago) is: - Calendar 42% - Display 38% - Cell Standby 8% etc.. Please help me out on this one.. I have no idea on what to do. The com.android.calendar process is draining my battery for no reason..
