So I posted this in a different thread but figured I would post it here to see if anyone could duplicate my findings. I have a Note3 from T-Mobile and for whatever reason leaving the Wi-Fi on will not allow the phone to go into deep sleep mode. I noticed when I was down to 40% battery after 10 hours with only one hour of screen on time. After running some tests I had only 2 minutes of deep sleep those entire 10 hours (tested using BetterBatteryStats) I tried setting "Keep Wi-Fi on during sleep" to Never and unchecking "Always allow scanning" under advanced network settings but neither of them fix the issue. In fact, after several tests I concluded that setting never for "Keep Wi-Fi on during sleep" wasn't even functioning as my access points still showed the client connected while the phone was asleep.
Can anyone else confirm this issue is actually a bug and not just my phone being defective?
Here's my original post on the topic regarding how I found the problem and what I have tested so far:
OK so after only 2 days of owning this phone (got it late Monday night, the T-Mobile variant) I finally figured out why I'm getting such bad battery, and I suspect the same thing may be happening for the other people in this thread. Hopefully this information helps at least one person.
My battery stats was almost identical to all the other users in this thread that had bad battery, I would get barely around 10-12 hours on the phone with less than 2 hours of screen on time. After using multiple apps to track down the issue I finally got what it was.
Wireless. Yes, wireless was my cause. But the thing is Wi-Fi didn't show up at all in any of the battery apps so I assumed it was a non issue. I've had other phones and have always kept the wireless turned on the entire time without problems. The basic problem is not that Wi-Fi is using power itself but it's that by default the phone cannot enter deep sleep while connected to Wi-Fi. This is why trying to use apps like BetterBatteryStats will lead you nowhere initially (though they were useful in finding out what was causing the issue) You can discover this by turning on Wi-Fi and connecting the phone to a charger, then disconnecting it so your BBS information will reset. Then power off the screen and power it back on after 10 minutes. You'll notice in the other section that deep sleep will have less than a minute time while awake probably has close to 9 minutes, if not more. This is with everything else turned off, almost no apps, and no special Samsung stuff enabled.
Under Apps > Settings > Wi-Fi > Menu > Advanced there are two options that should help this: "Keep Wi-Fi on during sleep" and "Always allow scanning" I set the "Keep Wi-Fi on during sleep" to Never and unchecked Always allow scanning and rebooted the phone. And low and behold...nothing. Yes, these options don't work (at least not to fix this problem) The phone still won't enter deep sleep mode while the wireless is enabled. Based on my company's wireless devices I can see that even with the screen off for well over 10 minutes it still shows connected as a client meaning the wireless is not turning off properly while it's in sleep mode. Or perhaps it can't go into sleep mode because the wireless is on which stops it from going into sleep mode and turning off the wireless. My guess is that it's a Samsung bug.
The reason why there's so many people here to get good battery usage is because they're either used to turning Wi-Fi on only when needed and keeping it off. You'll also not notice it if you have more than 6 hours of screen on time because you could easily assume that it would make sense that you phone would only last 10 hours total with that much screen on time, even though it should have technically lasted 20+ hours with only 6 hours of screen on time if the phone could have entered deep sleep.
So what's the real fix for this? Unless it's by design my belief is that it's a bug and won't be fixed until Samsung/T-mobile notices. I can't test to see if the same thing happens on other carriers so if someone feels like testing this theory out it would help.
For now, I guess we're just left to manually turning Wi-Fi on only when needed and leaving it off in all other cases. For those that have the T-mobile variant, make sure you also go into Settings > General > Backup and reset > Collect diagnostics and uncheck the "Allow Diagnostics" as that will probably be the highest offender of Partial Wakelocks (it'll show up as com.carrieriq.tmobile.wakelock or System Manager Application)
If anyone wants more information on my testing let me know!

That's because the 'Keep WiFi during sleep: Never" setting only disconnects, it doesn't shut down the WiFi radio.
You're going to have to use a manager (Like Deep Sleep Battery Saver).
Or just hit the toggle yourself... If you're going to keep it disconnected in sleep anyway, just swipe down the notification bar and hit the bloody toggle.

The problem is that it doesn't disconnect, the access point 100% shows it is connected and transferring data every now and then. But the real issue isn't weather it disconnects or not but it's the fact that Wi-Fi will not allow the phone to go into deep sleep mode. For now I am fine with switching Wi-Fi off and on as needed, but with no other phone have I needed to do this before and definitely seems like a bug.
But regardless, what I'm trying to figure out if this is a legit bug that I should submit to Samsung/T-mobile or if it's just my phone and I should ask for a replacement. If anyone has BetterBatteryStats and could test this with their Note3 that would help.
My stupid phone has just started this same issue!!!! Freaking annoying, after only 8 hrs from 100% charged state, the battery is at 46% with only 26 mins screen ontime, I checked out that the phone never goes into deep sleep. What is going on and what can be causing this? Did you manage to resolve your issue?
PS I checked out wakelock detector but doesn't tell me a thing, as what program is keeping the phone awake all the time. Starting to hate this phone and miss my S3
What is your GPS accuracy setting set to? GPS, Wifi or Networks? Try setting it to GPS only.

Well, your issue looks pretty similar to mine, which I solved with this Xposed mod (you could give it a try if you're on KitKat): http://forum.xda-developers.com/xposed/modules/mod-wi-fi-deep-sleep-t2752947. I was experiencing that even when "Keep Wi-Fi on during sleep" is set to Never, Wi-Fi still was awake most of the time according to battery stats.
I am pretty impressed with the G2 battery especially while in use. I originally got the phone and was in awe how it would go 3 hours from full charge with still 100%. So last 2 nights wanted to see what it was like all night. It looses about 2% per hour. Not terrible but Gsam shows the phone is awake for like 7 hours. I have messed with some setting and such and I will turn off for an hour then recheck. Right now it shows it was awake for 42 minutes and off the charger for 43 minutes. Woke device 8 times with 127 wakelocks. Cache update service for 42 minutes. 2% in 45 minutes battery. So the question is, how quick does the phone go into deep sleep.

it sounds like you have the 'wakelock' problem. is it google services or android system thats taking up all the power? i have that problem on my wifi at work, for whatever reason. when im on that wifi, NLPwakelock is constantly waking my phone and keeping it from going to sleep so my battery drains quickly. if im on my wifi at home or on 4G LTE then i dont have that problem.
trying turning off wifi. if you are still having the problem, you might need to turn off location reporting and location history under google settings -> location, and access to my location under settings-> location access. see if that helps.
And there's nothing I can do about it. I only have a gear s2 connected at all times and wifi and mobile data off whenever possible. Before I leave to the gym battery is at 44%. After the car ride there it drops one percent. I unlock the phone, connect my powerbeats, and open youtube and there go another 5%. After a YouTube video there is 7% drain. About a 10 minute video too. Leaving the gym and hour later and I see a maybe 20% battery loss. I don't know how people with regular S7s get 4-5 hours SOT because I get only 3.5 maximum. I bought the edge looking for better battery life but it's practically no different than my S5. If anyone knows a magic trick to this, I need to know now because this is extremely annoying.
IF you got the device from an official retailer, just return and get a new replacement. Losing 7% watching a 10' video is not right even with max brightness. You can fix the standby drain by using Forcedoze (which helped reduce my standby drain by 50% to about 1% every 2 hours). 3.5 hours SOT is terrible even with max brightness. Just get a replacement please. It's not worth the time and frustration.
IF you don't have the option of getting a replacement. Forcedoze can help with the standby drain. Factory reset, set up normally (personally, I just turn off bluetooth NFC location and turn them on when needed), and hope that your terrible screen on time is software related.

Do you think it might be my location by any chance? Maybe the service in my area causes this drain. I also have gps on because of my gear s2 but I can turn that off and see what happens. GSAM tells me the in the past 30 minutes the drain rate is 15% per hour. I browsed the Internet a bit and have been using it the whole time. I'll try to also do a full battery drain test on geekbench with full brightness and see what it tells me.

It's a good possibility. I have a fairly weak signal where I am most of the day and only get about 4-5 hours of SOT. I have all radios off except WiFi and data when needed. Still with my usage I only charge every 2 to 3 days. I don't get the drain like you do from watching youtube though.
My battery life also sucks. I barely use my phone during the day and it almost dead when I go to sleep. Most of the day I am connected to wifi between my work or home. My old htc m8 one could last 40 hours. I think part of the problem is because I do not have root on this phone. I kind of regret switching because I cannot get root. I cannot use applications to adjust cpu or control my wifi, data and to turn off apps from starting automatically. I think tonight I am going to try and calibrate my battery.
I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....
Guys, I had terrible battery life when I first got the phone. Off the charger at 6am, under 20% by 5pm... Follow my steps below and I bet your battery will do a 180 and be very nice. Mine gets me 35-40+ hours on a charge.
Disable the bloat apps you don't want in app manager.
Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

I installed forcedoze and did the adb non-root command and now my phone's battery is holding up better. I think the phone was just sleeping.
It's ridiculous one has to do all this to get closer to acceptable battery life.
Google and SEC should be ashamed of themselves!
It's not just VZW devices either. AT&T are just as bad.
I've given up on trying to get acceptable standby drain and just let the device live on a wireless charger.

You need to turn off all radios when you go to sleep for the device to enter deep sleep. I had the same problem and when I started turning off wifi and mobile data for the night GSAM reported deep sleep and I was only losing 3% per night.

I keep all my radios on (BT, LTE, and WiFi) and BBS and GSAM Pro all report that my phone goes into Deep Sleep.
I've had my V20 for just over 2 weeks now and found something strange regarding wifi.
Normally I set my phone to keep wifi on, even when asleep because cell reception at my office is spotty and staying connected to WiFi used to keep the battery taking a hit during the day. But, I left my phone off the charger overnight last week and saw my battery drop 11% in just under 8 hours. That seemed higher than my old phones so I installed BBS to see if anything was misbehaving when I'm not using my phone. To my surprise, no apps were causing a large number or long duration wake locks but my phone was only in deep sleep for 25% of the night when left off the charger.
While I was testing different configurations I left wifi on, but set it to disable when sleeping and sure enough, my phone stayed asleep for 80%+ and the 8 hour drain dropped to 5%. I havent been able to find any other combinations of settings that get the phone to sleep.
Has anyone else seen thing on their V20?
Only 4% drop at worst over night with Wi-Fi left on here.
Hey shwnr11, thanks for the reply. Just to clarify, you had the setting "Keep wifi on during sleep" set to always as well?
I always have wifi on at home, but unless I set wifi to turn off when sleeping, I see the drain.

Does this help....see pic
Yep, that's the one. Different wording on the Verizon V20, but same idea. Guess I've still got some searching on my end!

Im on a lg v20 with the same issue. My battery gets destroyed at work when i keep wifi on even with screen on iit driops 25 to 30 percent.
Hello, when I bought the phone from the seller, the battery was good, about 2 months old. I downloaded another one, I do not remember what the region was before, and what baseband was and build number. So I installed xeu region software. I'm using the firmware for about 2 weeks, everything is fine, but now it's obvious that there is a problem with the battery life. before rebuilding the data, dropped overnight by 1 or 2 percent since I locked it, like 12h lock, after 9h not using one percent or two down but not 10. Wifi is off, the location is on (high-level mode) and increase the accuracy when wifi is off and bluetooth is off, scan automatically, as I turned on this feature in place to increase the accuracy of the location. with battery saving mode i want explain for understand humans turned in location settings wifi scanning while wifi is off and bluetooth scan when bluetooth is off too in location settings. and battery saver turned on in settings backround data and wifi while screen off when battery saver is enable. and from wifi settings while screen off turned off wifi. after these settings battery dropped down 10percent after 3hours. i full charged yesterday i unplug and non used two or 2:30 hours battery dropped from 100 to 99 thats normal. but how gonna did that? 71 ,to 60 per 3 hours???? phone is locked and no background app, location is on but dont remember or i ticket in settings location wifi and bluetooth scanning while off........ before last factory reset without battery saver mode dropped 1 or 3 percent per 8 hours of non-use .. I remembered that I turned on backround data and wifi when turn on battery saver in battery saving settings. all background apps are off. wifi off when the screen is off I changed from always to never which exteneded more battery saver. The battery has dropped down 10% over 3hours. before last factory reset without battery saver the battery dropped overnight by only 1-2 percent. i dont remember when i switch I turn location on or not . and wifi and bluetooth scanned is on when wifi is off.
after last reset from 71 to 60 battery dropped down after three hours with wifi is off when screen is off , location mode is on high level, and i cant remember was on ticket when wifi and bluetooth even is off, i mean never turned bluetooth on when i go to sleep and from battery saver mode ticket backround data and wifi to on when battery mode is on..
