I got my S6 edge for a month now, I still the configuration and customization of my Nexus 5 and z10
recently the battery life of my phone getting pretty bad, only can last me for less than 10 hours for a mix of heavy and moderate use.

this is the snapshot from GSam Battery app after I woke up in the morning (was using my sleep app to track the sleep). The kernel and android system used a lot of the battery, is that normal? And also i can see my wifi is using somehow a half of my battery, should I change any setting to lower the battery consumption? :'(
