Run
Wakelock Detector. I'm assuming you haven't rooted your phone (if you have, that's all you have to do), so read
Wakelock detector with non-rooted phone. It's a bit of a pain, but two times (once after a normal workday cycle, once after a normal weekend day cycle) should be enough to give you an idea of which apps are keeping the phone awake. Then run
Greenify and Greenify those apps. (I run all my apps Greenified, except those I want to be able to run by themselves - like phone, texting and email, so I get incoming ones without having the apps running constantly, and the alarm, so I don't have to run it to get it to ring [which kind of defeats the purpose of an alarm - if you're already aware that it's time to turn it on, you don't need it]). My phone (a Note 3) can sit for at least 2 days before the battery is down to 40% if I'm not using it. I've actually gotten 4 days once - nothing happened, no email, no calls, and I checked it about every 8 hours. It seemed as if it was never going to drain.)
Also, when you're looking at the Awake line, look at the Mobile network signal line. If it's not solid green, it's costing you battery because your carrier has a weak signal where you are (so look where you spend lot of time - home, the office, etc.) The only solution to a weak signal is changing carriers to one that has a strong signal where you usually are (which is why choosing the carrier by actual test driving is the first decision in getting a cell phone if you don't have an account, of if you're off-contract. For instance, Sprint has some great deals - and is useless in my daughter's house, so I eliminate them right off the top.)
