    I have the S7 Edge but still see the same thing. It doesn't worry me.

    I noticed that my phone appeared to re disconnecting and then reconnecting to wifi fairly frequently at work; a reset of the router appeared to fix that issue. I also turned off the network scanning for bluetooth in the location settings of the phone (note: just turning off bluetooth does not affect this, because the network scanning feature is to allow a scan of networks even if the radio is turned off by the user).

    So far today, the battery life is much better - tracking to a 25% longer life and SoT (I was getting 15-16 hrs life with 2 hrs SoT, now on track for 20+ hours life with 2.5-2.75 hrs SoT). This is all with my news apps refreshing, Outlook app, Gmail, and Exchange all set of push for multiple folders, weather refreshing, etc.

    By the way, it looks like a ton of people posting here leave their phones on and unplugged overnight - what is the reason for this? I was fairly certain that Li-ion batteries do not suffer memory effects, and the lifetime is a function of total discharge and charge cycles (i.e. 2x charging from 50% to 100% has same impact as 1x charging 0 to 100%). The "conditioning" that people used to recommend did not do anything to the battery itself, it was more of a calibration for the battery controller so that it would correctly recognize the zero point and 100%.

    What service provider do you have? Also have you thought about doing a factory reset to completely wipe the phone.
    You can also trying wiping cache instead of a full wipe. Do you have GPS turned on? In settings I make sure I turn off any AUTO update features along with the smart controls. That seems to help a lot. Yesterday I got about 5 hours of on screen time and a full day and half of battery life. Which to me is pretty good. There is no way that would have happened on my S6 edge
    Where do I find those settings? Thanks

    I fully charged and left it unplugged overnight to test battery life during idle (when phone is not turned on, with no apps running in background)
    S7 battery drain has nothing to do with the battery itself. it's Qualcomm Snapdragon SoC problem.

    No. Nova. Noooooooooooooooooooooooooooooooooooooooooo.

    After much dismay and using Nova for over 7 years, I had to let it go. Long story short, Nova Launcher was keeping my phone awake the entire time the phone was on. I am NOT saying that it's everyone's problem, but unfortunately for me and MY phone it was causing my phone not to deep sleep. After removing Nova, I began to setup Touchwiz, my phone rebooted by itself and the phone was super warm. After removing it, my phone now sleeps like a baby. I expect that my massive drain will end. Again this may not be everyone's problem, but for me I had to let it go. Sorry Nova, Touchwiz works just fine for me right now.

    Do you have a screenshot of Nova eating battery?

    I am using it, phone does not seem warm, not the best battery life but im sure it's something else, nova never showed in my battery list.

    Not sure if this has already been pointed out, but understand that the battery percentage numbers are a zero sum game. The total for everything MUST add up to 100%. It looks to me like any battery use that isn't directly attributed to some other specific user is simply lumped into Android System.

    Don't worry about how much battery Android is using. Worry about how your overall battery life is. For me, this phone gets better life, and more screen on time, than any other phone I've used.

    S7 battery drain has nothing to do with the battery itself. it's Qualcomm Snapdragon SoC problem.
    Apps are running in background sleep they won't show info stats until battery drops to 96-98%.
    As far as Snap being the culprit I highly disagree , my usage detail posted in this thread shows this.
    It comes down funky setting , bleeding app or WiFi 5Ghz causing battery distruction.

    How do you determine what prevents the phone from deep sleep?

    Same here, and I'd love to know if this is why I'm getting 2.5-3.5 hours of screen on time vs others 6+. I have wifi set to turn off when asleep, but per gsam, the wifi never shuts off. Something must be keeping my phone awake....

    I had all these issues and my battery was draining too fast. I uninstalled Nova and then reset back to factory. I then started putting my apps back on the phone. I dimmed my screen. I've seen a great improvement in the battery. Yesterday I had a full charge at 10:30 in the morning. When I went to bed at 10:30 my battery was at 40%!

    Good tip. Just made the change on my Verizon Note 5 with MM. Have good battery life regardless, but will take more. My wife also has a Note 5 and while she does have much more SOT that I typically do, has not been getting as good battery life as me on a relative basis. Will change from Global to CDMA/LTE on hers and see if that makes a meaningful difference.

    Settings-Application Manager-Click on the app. Look at memory. Nova Launcher uses too much memory.

    Again, once I removed Nova, my battery has been phenomenal.

    Right, but how did you figure it's keeping your phone awake? Also, memory usage and battery usage are two different things. If Nova shows under battery stats with some high number, that would be concerning but it usually runs around 2% which is nothing and very much normal. Your battery life may be phenomenal but it's not because you removed it ...

    Right. If you say so. I know what happened to My phone once I removed Nova. Again I love Nova been using it for years. It just doesn't work for me on this particular phone.

    ...and it seems fine. How much is "too" much memory?

    Turn the phone off. When the phone is off Hold down the volume up button, Home and Power button while the turn phones back on. Do not release until you see the android logo. It will then boot into recovery mode. You will see the cache wipe there. The volume up and down move and the power button selects the option.

    Noticed "Applying System Update" or similar once phone booted into Recovery. Although I have a Note 5, the instructions are the same, and I have not cache wiped since I've had the phone when it was on Lollipop. It's been awhile since I have gone into Recovery. Is the "Applying System Update" normal now? I didn't see any updates waiting for me when not in Recovery. The VZW CSC in particular was what updated.
