About 6 months ago my Note 4 suddenly lost half its battery life. No new applications were installed at that time, but there was a "security update". I've replaced the battery twice, but the significantly reduced battery life continues.
I purchased BetterBatteryStats to help understand what's going on.

The only thing that caught my attention is Wi-Fi On and Wi-Fi running are both 100%. Is that typical? If not, what settings control it?
I have "Keep Wi-Fi on during sleep" set to "only when plugged in", and "Always allow scanning" is unchecked.

Also I noticed that the log says "Root perms: false", but this phone has systemless root.
