My phone's OS is cyanogenmod 12.1 with Android version 5.1.1.
Recently I found a battery drain. I set up the airplane mode but after a night the battery went from 100% to 41%. I viewed Settings->Battery and found that the sum of battery usages of all apps was much lower, approximately 20%. I need to know how to fetch a verbose log for the battery usage in order to diagnose the issue.
Thanks very well.
