I have noticed that the WiFi on my note 4 drains 30% of the phones battery on average and this exceeds the battery drain of the screen even with an SOT of 4 hours.
this is easily overlooked because the stock battery monitor does not show how much battery WiFi consumes. It only shows if its on or not. However the GSAM app will show it.
My phone is an n910c.
Smart network switch and WiFi scanning are both off. Phone is connected to a stable WiFi but when in the WiFi menu it shows that its scanning ever few seconds. this might be normal.
Attached are screenshots of battery consumption of WiFi and my settings.
Please post here if you have the same issue.
I find the GSAM app very incorrect, just look at the SOT, my said max screen on time per charge like 5 hours while i was at my 6th, so automatically was wrong.
Scanning is off for lication services but you have notification for open networks which requires frequent scanning and you have keep alive during sleep.

If you have set your Location service in "high accuracy" or "power saving" modes, then you have also permitted use of Google's location service, which scans wi-fi and/or mobile networks at all times - including when you have supposedly turned your wi-fi "off".
Have you tried a reset of your phone and see if the problem is still there?
Is that an n910c?

As stated in my signature: SM-N910F
Just got confirmation from another n910c owner that the WiFi can account for up to 53% 53% of the battery consumption when turned on. From what I see on the battery thread, the n910f even when connected over WiFi for 40 hours only takes less than 3%.
If we figure this out we will definitely be seeing Snapdragon like battery life.
I'm trying to combat this myself. On another note, how do you have access to WiFi Timer? I don't have that as an option. N910V 4.4.4
That would explain so much. The phone still lasts me a day but I was always surprised by the WiFi battery stat in GSAM and thought it might just be reporting it wrong. I hope this issue (if it is indeed one) is addressed in the 5.0 ROM magically ;_;
I too had massive battery problems. I couldn't use my phone for more than 8 hours.
Then I downloaded this:
https://play.google.com/store/apps/details?id=com.rrr.android.mediaserverkiller
Set it to kill the server every 1 or two hours.
Now my battery lasts three days!
N910U wifi is 3% for me
Thanks for the datapoint ausboy.
Seems like n910c is the only variant affected.
Samsung should take note, this is why the battery life on the n910u is much better even though both are exynos.
I'm on 4g now and the battery life on 4g is way better than with wifI on. I've tried different routers and it doesn't make too much of a difference.
Not sure why you guys are getting such poor battery life I am getting consistently 7-8 hours screen on time with location on Bluetooth on connected to my gear s sync on pushing 5 email accounts wfi about 75%and when I lte I don't really have a good signal most of the time - I also have a 10,000 mah zero lemon battery but I get such good battery life with the stock battery it is never really needed the extra time
And do you have the n910f or n910c?

There is a exposed based app called amplify which you can chance service scan times for pretty much everything. Highly reccomend.

I actually meant the feature that let's you set up specific times for WiFi to be turned on automatically. I've got a third party app for that currently and would prefer to have the Samsung version.
Can anyone with the n910c try other firmwares and report back if the n910c still experiences the same problems?
So far two users with the Malaysian firmare experience this wifI battery drain issue. I'm not sure if the others are on the same fw.
Hi, I have been noticing that I have not had that great a battery life as with other users of the note 4. Was searching all this while for an explanation until I came across this thread. I am also using a SM-N910C with XSG firmware that is UAE and am also facing this drain. I installed GSAM as you mentioned and can see that Wifi is accounting for up to 27% for me. I will post the screenshots once I run through and entire charge cycle.
Had earlier contacted Samsung online support about the same but they simply asked to go to a service center and get the battery checked. But I guess that this is a particular issue to only the N910C.

I m with pre-installed firmware from U.A.E, no root, no disabled app, using as it's came out of the box, SM-N 910C
For some reason after the 5.1.1 update on my T-mobile Galaxy S6 it was running hot and looking at the power consumption it was draining the battery quickly. It drained about 15% of the battery in less than an hour w/ nothing running in the background, and the battery usage is displaying 1% for everything for some reason. The one on top is com.tmobile.pr.adapt.
I wasn't sure if T-mobile pulled something stupid like making one of their apps that communicates to their network, but only over their data (i.e. not over wifi - like they do with showing your account information.) So, I turned off the WiFi to let it run off of LTE for a while. It cooled down and power consumption went back to normal (for being on LTE.) I let it sit for a couple hours that way, then switched back to WiFi and within a few minutes it was heated back up and power draining fast for some reason. There's no indication of things being downloaded but it's drawing way too much power.
Note I've rebooted it 3 times w/ same type of power activity.
Any thoughts, and anyone know how to role back to 5.0?
If you took the ota or used Odin to update you can't downgrade. I told everyone first thing this morning a downgrade won't be possible. Have you done a factory reset since updating?
I did a factory reset when I updated and battery life has been good with no strange issues.

Haven't tried a factory reset yet. I figured I couldn't downgrade as that's typical. I left it overnight w/ WiFi enabled and it drained downfrom 100% to 60% within the first 2hrs and then started draining slower to about 36% over then next 10hrs.
I topped it off w/ WiFi turned on and it felt like it was running hot. Left the house to run some errands for an hour and it only dropped to 96% (WiFi turned on but not connected.)
I've just got back from that, I'm going to let it sit for an hour w/ WiFi on but will leave it sit and see what happens. Personally I don't want to do a Factory Reset but if I'm still having the issue that's where I'll go. I had a similiar issue for a while on my S4 but it went away after a couple weeks.
EDIT: Ok, almost an hour later and it's only dropped about 3% while the WiFi was enabled and connected. I guess whatever was causing that has settled down. Thankfully no Factory Reset was required.
It is because of a stupid bug on WiFi calling (the mobile antenna does not turn off and it drains the battery). If you want to use wifi, just disable wifi calling, and you should be ok
I'm having a similar experience as TAZ427. Just updated my T-Mobile GS6 edge to 5.1.1 with OTA. I immediately noticed the phone was somewhat warmer. Battery monitor reveals that com.tmobile.pr.adapt is now #1 on the list. I tried killing that process several times but keeps coming back.
I also notice that despite being connected to my home WiFi, the "4GLTE" icon comes on and off constantly (1 second on, 3 seconds off, repeat...). Before the update, 4GLTE rarely came on while on WiFi. So probably the increased battery drain and heat are due to radio usage, not necessarily extra CPU utilization.
Not sure what com.tmobile.pr.adapt is for, or if it can be disabled. Would love to hear any guidance on that. As a side note, I had TMO grant me a SIM unlock -- I'm actually on Straight Talk (AT&T MVNO). So this service is running despite my phone not actually using the T-Mobile network.
I'm going to continue observing for the next couple of days before doing a factory reset. Really hoping to avoid that...

I think I found a semifix, someone else will have to investigate because I have no idea what I actually did or if it's a longterm fix...
Go to Data Usage in Settings, find com.tmobile.pr.adapt or whatever it is, turn OFF Background Data. Go to Application Manager, find com.tmobile.pr.adapt and Force Close, Clear Data. I wasn't able to disable it but it seems the Background Data being turned off fixed it.

I am having the same issue and my phone is not usable now since the battery is awful. My s6 is temporary unlocked for a month since I am out of the states. I am afraid this is happening for unlocked s6's only. The trick of restricting background data for the "com.mobile.pr.adapt" seems to be working for now.

My S6 is not unlocked, it's a T-Mobile variant right out of the box activated on MetroPCS. If I had to venture a guess it would be that this is only happening to phones not on T-Mobile, not necessarily just unlocked. I'm assuming that com.tmobile.pr.adapt is some kind of phonehome or data reporter for T-Mobile but since we're not on T-Mobile it keeps bouncing back and getting stuck in some stupid loop.
I have the same problem with my unlocked t-mobile device (running on att). I wouldn't be so pissed if the update at least fixed the memory drain, but noooooope. Now I'm stuck with a 450mb phone that crashes and has bad battery (last two are new).
I did that small hotfix, and will check back.
Has everyone cleared the cache partition? Since the update, is the download booster automatically set to on?

The download booster is set to off after the 5.1.1 update
Happy to report that for me, this "com.tmobile.pr.adapt" issue has effectively gone away. Things started getting better after I cleared the cache and data for this process. I also restricted its background data as was suggested by others. Not sure which of those actions did the trick. Just theorizing, but another possibility is that T-Mobile was simply collecting post-update metrics from their phones for QA purposes, and that this was all just a short term annoyance. Anyone still seeing battery drain and heat higher than normal due to this process?
Anyway, "com.tmobile.pr.adapt" is no longer registering on my battery usage menu, or on CPU utilization list when I run OS Monitor. The phone is performing well overall (no worse than before the 5.1.1 update, anyway).
Excellent battery life for me. I had over 17 hours in total & 3+ hours on screen time. Only problem is i cant seem to install downloaded apps manually
Thanks

After the 5.1.1 update this morning my S6 went from a 100% charge to 10% in about 2.5 hours which was disheartening. Tried a factory reset which didn't help. Even charging from a USB port didn't stop it from draining the battery (just drained slower)! Called TING and they had no idea. But this seems to be working for me too. Thanks!!! I'll email TING to let them know about the fix, may help with a future update?

I think it has more to do with T-Mobile pushing a fix or an update, because whatever they did to 5.1.1 on their end royally screwed anyone using their branded S6 on another carrier. I don't know the proper channels to make T-Mobile aware of this.
I have the same annoying problem on my 920T. I bought it from t-mo, unlocked it and am using it in Italy. As soon as I got the 5.1.1 update, com.tmobile.pr.adapt started killing my battery. I just enabled the "restrict background data" and will let you know how it goes...
Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?
Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.
I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.
There is something wrong with your phone or app. I have about 100 apps. No problem here.

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).
How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.
Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.
Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.
Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.
I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.
Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.
So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.
I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.
I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.
I've found several threads about drain, but all of them are Android 5 related.
Unfortunately I still have this problem on Marshmallow.
I don't notice it when using the phone, but while idle, it drains battery. Attaching the screenshot indicating I charged my phone at around 10 pm and at 1 pm next day it was already at 15%. Screen on time was only 2 hours.
Wakelock Detector does not work on Marshmallow. Installed BetterBattery Stats to try to find out what's causing this, but If any body's experienced it and has any idea what should I do, please share your opinion.
I've got MRA58R, bootloader unlocked, rooted, root aps list is: call recorder, adaway, betterbattery stats, es file explorer, gmd gesture control, nexus 6 double tap to wake.
Don't know if any of this is really important, but still. The rest is pure stock installed with full wipe.
PROBLEM SOLVED:
Nexus 6 on Android 6 has bug with 5 Ghz WiFi networks, use 2.4 Ghz and your battery will be fine!
Today before going to sleep I charged the phone to 100%.
I left it with wifi on for the night. In the morning after 8 hours I had 65% left. Screen on time was only 42 mins.
Attaching screens from battery and better battery stats.
What should I do next?
I would appreciate any opinion.

This. I had a similar issue a while back (although it didn't happen every time). One thing someone told me was to avoid the 5g band on wifi. Whoever it was correctly determined that I was connected to the 5g band of wifi at home and suggested I use it on the 2.4 instead. I did so and my drain dropped significantly. Now if I charge to full, leave it on my nightstand overnight off charge, I wake up 6 or 7 hours later and lose *maybe* 1% per hour. That's with wifi, bluetooth, gps all on etc.

I'll keep my fingers crossed for you that this fixes the issue. Additionally I should have noted, the person who suggested I use the 2.4 band instead of the 5 specifically noted that there is a documented "bug" where 5g wifi bands cause significant drain. That's apparently the reason that 5g specifically tends to be the culprit.

I will then test 2.4Ghz WiFi to see if it's really only 5Ghz WiFi that's causing the problems

I have a similar problem as well. I have had wifi turned off all day today and its at the top of the list on battery usage. I have looked at every possible wifi option and turned it off. I dont understand what could be causing this. Im only bootloader unlocked, non-rooted, running stock image MRA58K

When you set it up did you set it to allow it to keep wifi scanning even when it is off for the location settings? I leave my wifi on 99% of the time and my battery life is great.

I dont remember if I did but I did turn that setting off when I was trying to diagnose the issue. I don't know if maybe it's a 6.0 bug that needs to be fixed. Good thing that being a nexus I hope it won't take too long.
I updated the firmware on my router and after doing thus none of my devices would enter power save mode on the 5ghz radio anymore and drain is now massive (check your router logs)
I tried flashing back to the prior firmware but still no go, so it must have been a driver update on the Quantanna radio as that's the only thing that was updated and it's a known issue with my particular model.
That helped me! Thank you guys! I connected to 2.4 Ghz and lost only 6% overnight!
I wish this information was easier to find, I'll update first post when I get home, it'll probably be useful to a lot of people.

It is a known issue with Quantenna radios on multiple routers; my ASUS RT-AC87 is one of them. Specifically as you said, on the 5GHz band. Switching to 2.4GHz wireless can fix this for the time being on Quantenna-based routers.
I've also had times where my battery seemed to have excessive drain if the cell signal dropped to non-existent; the N6 appears to drain fairly quickly searching for a signal. Unfortunately, AT&T occasionally drops in my house, and that's the carrier my work is on, so I have to live with it.
I have had extremely terrible battery life with this phone since the day I got it in April. Probably the worst ive had with any phone ever and ive had dozens. My cell standby is at 147% in the battery statistics. Absolutely nuts! I had a manufacturer replacement so it's not my actual phone. I live in a fringe area that dissipates between 0-3 bars as well as switching between 3G and 4G which is obviously no good for the battery. I recently figured out that you can just turn off cell signal with airplane mode and then turn wifi and wifi calling back on so that there is no cell standby. I thought it would help but my battery is no better. Can someone please help give me some insight into what gives? I just don't get it. Such a great phone ruined by such a terrible terrible battery. BTW I have all my downloaded apps optimized, limited sync only for gmail,location off, screen brightness very low and I have package disabler pro installed with the known tmobile battery hogging apps disabled.
Do you have Google now enabled? Disable it if so, also go into wifi advanced settings and disable wifi always scanning if it's enabled

I have all advanced wifi options disabled , no Google now. Just checked battery usage. Somehow with airplane mode on and only wifi and wifi calling I have even more increased cell standby. It says 179%. How could that be. Even if I was struggling for signal that hardcore and I wasn't on airplane mode I have never seen anybody ever report there's to be THAT high.

There is something seriously wrong with your device. That's not normal drain, it's not even possible. I would either talk to T-Mobile or Samsung about a warranty exchange

Right, I understood without airplane mode on because my phone is literally constantly switching between LTE and Edge but how the hell would that be happening with the radio off lol. I could be being misled by the battery stats by not giving it enough time after trying airplane mode. Could be the left over stats from before. I only tested it for a couple hours. Visually to the eye it didn't seem like the battery life was much better though. I wonder if wifi calling is an issue or cause? I can't do a warranty replacement. I already used one because my first S6 had some random line of of bright light suddenly go through it that wouldn't go away. I really dislike this phone lol. Wish they'd just let me replace it for something else entirely. I miss CM. Now it's at 242% but it says time on 2 days 11 hours 46 minutes , time without signal 38%, total connection time 1 day 19 hours and six minutes, so maybe the high percentage is just because of how long the phone has been on with out a cycle. I only tried airplane mode for a little while one day and ever since I left it off. Why idk.

You should be able to get a replacement anyway, don't know if having insurance matters but at least for me, I've swapped previous devices multiple times for a replacement. Try doing a factory reset and charge the device to 100%. Only install the minimum apps to get you through and try that for a full day, see how that works out. Also make sure you are on latest firmware which at the moment is DOJ7

Yes I am on DOJ7. I was stock for the longest time then I decided to root and try some roms. Didn't like much of any and I wanted the DOJ7 update so I flashed back to complete stock. I did notice a tiny bit better life on some of the roms. O and I have factory reset before as well as wiped cache. They'll probably do a insurance replacement but I think the warranty one is only once. I think there's a deductible for the tmobile insurance replacement too but whatever I'll give it a go.

Deductible is only if it's your fault, like breaking it or getting it wet. If something is wrong with the device, like manufacturing defect, the most they should charge you is about $5 and you get a replacement shipped overnight

Crazy lol. Maybe I did something during root? First time I ever tried I messed up and got the phone stuck in bootloop. I managed to fix it and get rooted and tried out several roms for a week or two. Then went back to stock once the latest update was available.

Is that on a single charge?

No that's over very many. Stats never seem to reset, it just keeps going up on that. EDIT: Ah it's finally reflected and gone down to 5% in stats. Actual feeling of the time still seems to be the same though. EDIT 2 : The stat is climbing again even while in airplane mode. Screw this phone lol.
