It appears that the S7 has the same problem that my S6 had. The bluetooth just being enabled kills the battery. I have a seperate work phone so my personal S7 spends all day collecting dust on my desk while I am working. I noticed the battery seemed to be dropping rapidly even when I am not using the phone. I did an experiment today. I was at 100% battery and I did not touch my phone for 4 hours with the bluetooth enabled. The battery fell 13%. I then disabled bluetooth and didn't touch the phone for 4 more hours. This time the battery only fell 3%! My S6's bluetooth did the same thing. The S6 did not have this issue when it was new but started eating battery after an update about 6 months ago. My wife's S6 has the same issue. Is anyone else seeing your battery drop quickly with bluetooth enabled?
The change in discharge rate is very apparent in the chart:

yeah, i posted a thread about this same exact thing. I use Bluetooth daily with my Moto 360 except on weekends, and this weekend my battery life was so much better than during the week

Try going into your Location settings, then the Improve accuracy section and turn off Bluetooth scanning. There's some Bluetooth background scanning on by default even if you turn off Bluetooth.

Anyone have any tips on what I can disable on a stock non rooted device to get my Android System battery usage down? It's always on top and is usually in excess of 25%. As it stands I can't even get a day out of this thing with only 1.5 hrs of screen on time.
Maybe the battery is bad, phone is only a couple weeks old.
Oh and I should mention that there's no wakelocks or anything strange, it appears it's a legitimate battery drain. My screen brightness is low as well and today I never woke it up outside, just inside abient light. WiFi is off as well.

A thread all by myself, cool.
Today my battery has been unbelievable, only dropped 28% in 12 with plenty of use. I don't know what to think.
Same issue here.
I've had the phone for 5 days now.
First 3 were a blast with over 5 hours SOT.
I am now getting little over 2 hours SOT thanks to Android System.
Lonely threads come with expensive devices. No support, No Roms, No Development.
Anyhow, For your issue, Try minimizing the permissions of builtin apps. Disable autorun, and use greenify.
Hi,
I recently had my droid maxx replaced because I was getting less than 2 hrs screen time and overall my phone lasted hardly 12 hrs. On the replacement, I have had the same problem and I haven't been able to figure out the reason behind it. I typically keep bluetooth on all the time because I have a moto 360 and bluetooth in my car. Additionally, I typically have my location services set to 'high accuracy' since I use gps to check traffic everyday via Waze (it's pretty annoying to have to turn it on/off twice daily).
One thing that popped in my mind today is that could NFC be responsible? I have a silicon adhesive that I use to store my ID, a credit card, and my ventra card (Chicago public transit). The ventra card uses NFC so I was wondering if my phone might be constantly reading it, and result in the excessive battery drain. Has anyone seen this before? Below are pictures of my screen on time along with the general battery stats. If the low battery is because I'm lazy and keep bluetooth/location services on all the time let me know - but I didn't think the drain would be that excessive. Any tips/advice would be great!

I finally have had my note 5 for a few days and so far it's really good! There is something that is really bugging me though and that is the standby time of this phone is horrible! And I'm sure it's not hardware related because:

This is definitely not normal, and it has always been like this from day 1. Idk why, but system and cell standby along with android OS are all using more battery than the screen. There is no doubt that the screen should be the greatest power draw by far on this phone, so that means there is something wrong here...draining my battery during sleep!
Anyone have any ideas as to what's happening?

Turn off VOLTE and WiFi calling.
What theme is that?
I tried doing that, and left my phone overnight at 95%. I woke up today and found it drained to 88%, Cell Standby and Android system being the top two equal drainers.

search for the thread about debloating the note 5 using package disabler. totally fixed the battery problem on my note.
This is what package disabler did for me. I'm more than happy, and is not even an aggressive setup. And Is not that I lost key features eother. The app has done wonders with my battery life.
Hi guys, i performed a factory reset to my opo, but now i have a huge battery drain. I think it is caused by the Wi-Fi but i don't know why. I disabled location, autobackups, ok google detection and stuff like these. I also noticed that the wifi is active also when the phone is powered off. Any advice?

The huge drain is caused by your weak cell reception. As you can see the drain is minimal right at the beginning when you were not using your device at all.
The drain starts at the same time when the reception starts to get bad (red).
But, you also started using your device quite heavily at that time (active + screen on for longer periods).
Were you on wifi all the time or did you use mobile data and only had wifi left enabled?
What was you screen on time at the end of the day?
Without more information about what you were doing with your device I would say you were on the go, maybe on a trainride with bad cell reception which uses much more battery.
To be honest the battery looks "OK" to me in this case.
About the gap + wifi usage, might just be a statistics bug, I don't know.
Charge your device and go on monitoring your battery... there are bad days and good days.
Before I was getting 14h total time, with 2.5h SOT time before being forced to charge.
So I did the fresh reset like was suggested. Battery life is FANTASTIC now..... SOT 30M, LFC 3.5h, time left 2d 13h.
However, if I flip on WiFi, my phone will drain quickly, for some reason, I think it is either constantly searching for new WiFi locations and/or it is keeping my phone awake constantly.
Anyone have a remedy for this?

Now look at it afterwards
I only got mine yesterday, but I have noticed the battery life is terrible also. I found a setting in wifi called 'scanning always available', which I have disabled, this might be our culprit.

I have been looking at that as well.
I would check for wakelocks while WiFi is on. I also double-check the app settings for syncing while on WiFi.
