I have constant wake lock and battery drain from android system. It is using around 50% of my battery life. When my screen is off it is 100% of the time in wake lock according to gsam. I tried a reboot and battery pull and I'm still getting the same. If anyone could direct me to something that will find the wake lock or if they know how to stop it, it would be greatly appreciated. Luckily my 2nd battery is helping ease this terrible battery life.
I have the exact same issue (on Verizon). I am going to give Wakelock Detector a try. Until then, I have become nearly certain that my home WiFi router is the biggest issue. This morning I reserved the IP addresse for my G4, and all the other devices on our home network, as suggested in an older online discussion I saw regarding this issue. In turning on the WiFi on the G4 briefly, the wakelock issues in Android OS seemed to continue. So the IP reservation didn't seem to help.
I'm going to split the WiFi issue out to its own thread, given it's a specific problem in and of itself.
Well, after several days of reinstalling a few apps that showed an issue I thought might suggest a deeper problem (i.e. not pushing notifications when it should be), and some trial and error things (i.e. shutting off Verizon Advanced Calling 1.0 a.k.a VolTE), I am all but certain that the Android OS issue with out of control keep awake times is the fualt of my home WiFi router.
Now, I don't have any obvious performance issues otherwise, but switching off the WiFi, or leaving the house, has seemed to slow the Android OS keep awake times to a crawl...until I reconnect to the home WiFi. I am generally not fsr from the router when at home, as well.
I'm going to try out Wakelock Detector to try and confirm this even more strongly, but I am 90+% sure the WiFi router is an issue.
So, what do I do?
This morning I reserved IPs for all the devices in our home network, including my G4. A quick toggle and check seemd to start the keep awake flood anew, so I don't think the resevred IP helped.
Are there any other things you would recommend? I have a Cisco Linksys AC3200 that is only a couple of months old. By and large it is speedy and reliable overall.
Now I wish I had taken screenshots of Android OS when I went cell radio, no Wi-Fi, and had 4 hours SOT with 24 hours up time. Could have helped with some analysis.
However, you and I seem to have pretty different Android OS keep awake times and I leave Wi-Fi on 24/7 for the most part.
I have a Netgear Nighthawk.
Are you able to run cell radio only for a full cycle to see if anything changes?

I ran this morning with just the cell radio and even without a full cycle the difference was immediatly noticable. I observed over more than 5 hours. Even switching the WiFi back on resulted in a noticeable increase in that Android OS wake rate.
I have seen the 2 hours in 5 or 6 hours rate go down slightly the past few days as a result of some other twweaks (or maybe just coincidence), but the rate with WiFi off is noticable after a short time.

Turning Wi-Fi off for the rest of this charge cycle to see what happens. I made notes of where I am now since I started at 100% and Wi-Fi has been on all day. I'll report back later.
Interesting. I have disabled my location and wifi right now and am trying to see if it will help. I wonder if it has something to do with using wifi calling, as that's what I setup recently. The wakelock detector isn't working but I'll give it another shot tonight.
Hasn't been a full battery cycle for me but my wake lock is still 100% of the time with wifi and location disabled. Disabled all my smart home and unlock settings but it did not help.
I disabled Google Now and stopped the location tracking. Turned my location to battery saving as well. My standby battery drain was even worse this time and I had strange gaps in my battery graph.
