    I just did the battery app optimization, and found that all the apps I've disabled are reupfgrading and reinstalling them selves and are no longer disabled. I'm going through the apps list now to re-disable them. Still haven't has the battery issues Sandman333 has had.

    I am really frustrated with battery life after Nougat- it was crappy enough before the update.

    I leave it on a Samsung wireless puck charger on my desk at work - I leave at 5:30 PM with at least 90+ percent, and I am below 50 percent by 8PM...and it isnt usage, mostly in my pocket.

    Currently at 81% , 3 hrs off of an overnight charge, with charging in between on the wireless charger. 4 hrs left according to the monitor.

    I'm working on a new theory now. For the last two days, I haven't had a battery problem with my phone. Just an hour or so ago, it started heating up and burning through the battery again. Once again Android System was at the top of the battery use list. I had made absolutely no changes to my phone between the time of normal battery operation and hot phone/massive battery drain. I still can find absolutely no reason why this is happening.

    However, this time I turned the Bluetooth radio off a few minutes after the phone started heating up. A few minutes later the phone was cooling off and battery usage seemed to have returned to normal.

    Can those of you experiencing this same problem try turning off Bluetooth to see if that makes a difference when this happens to your phone?

    Bluetooth has no effect for me. I have it off during the day at work, since for some reason it interferes with my WiFi connection at work. It still drains ridiculously fast.

    As far as my phone goes, I'm fairly confident at this point that the problem is Bluetooth related. If I keep the Bluetooth radio shut off, the phone doesn't get hot and battery usage appears normal. If I leave the Bluetooth radio on all the time, I will eventually experience the hot phone/massive battery drain problem. When it's doing that, if I shut the Bluetooth radio off, the phone cools down and battery usage returns to normal. The weird thing is that I can have the Bluetooth radio on for days without a problem. Also, every time I experience the problem, Android System is at the top of the battery usage list. These factors make me think that this is a software, rather than hardware issue.

    My Moto Z Play Droid gets terrible battery life when connected to my BT headset.

    If you've done a factory reset and are running a trial of visual voice mail again, that can be causing massive drain. End the trial (settings icon in upper right hand corner) and see if that helps.

    Sandman333 and others, any further luck? I realized in past week that my Nougat DT2 is also exhibiting this *exact* behavior, randomly very hot even in standby, plus very rapid battery depletion (4 hours). Disabling Bluetooth did not help.

    Verizon Visual Voicemail is suspect to me, as a week or so ago, I coincidentally enabled its free trial for the first time (due to my third party YouMail voicemail app crashing frequently). I've just disabled the free trial to check if that solves this heat/battery problem. Unfortunately it looks like this VZW app cannot be uninstalled or disabled.

    Has anyone else had luck with disabling Visual Voicemail?

    I made a practice of turning my Bluetooth radio off when I wasn't using it, and that seemed to have cured the problem for a long time. For several weeks now I've left Bluetooth on all the time and have not had the problem return...

    Thank you cjp39, this did the trick for me! Phone no longer running hot, and battery life is *way* back up. In fact, battery life seems better than ever now, though that could also be related to calibration cycles I've been doing.
