Note 5 SM-N920I battery drain issue, Nougat 7.0 - Galaxy Note5 Q&A, Help & Troubleshooting

hello,
just updated my note 5 to nougat 7.0.
realised there is a significant battery drain.
during my 9 hr of sleep, battery level dropped from 90% to 70% with mobile data off, GPS off, Bluetooth off, NFC off, sync off, google location service off.
I tried clearing cache and Dalvik cache, didn't work.
I tried resetting app preferences, didn't work.
kernel and android system takes up most of the battery

1)Your probably facing deep sleep issue but AFAIK deep sleep is already fixed there in official nougat 7.0 by sammy, Primary solution you can try is to factory reset your device If not helps
THEN
2)Either wait for next official OTA release for your device Or Try any custom pre-rooted rom with Deep-Sleep Fixed on side of kernel

I have the same problem as you. My battery drain is horrible. I get maybe four or five hours before I have to plug it back in. When I have my Note 7 I could take it off the charger at 7 in the morning and at 10 at night when I got home I still had about 70% battery. I sent mine back for the recall about 4 months ago still haven't got my money back from Samsung. As I wait for that check I bought another Note 5 and flashed the Note 7 ROMs the S8 plus ROMs and every other ROM and this phone just has the worst battery life especially after using the Note 7. The best thing to do is find a light type ROM with a lot of bloatware uninstalled and run Greenify

You know I just bought a Galaxy Note 5. AWESOME price. And was made Feb 2017.. wow. I did by one a week before that. It was N920a. Made 2015. WOW was it slow. And still on Android would never update. So sent it back.. got this on N920I and was on 6. I never read anything about battery problems. And it updated to 7 RIGHT away. Loved it. I tried 2 programs ..had to do with themes. WOW the battery drained SO fast. NOTHING was running. So I deleted what I put on. Those two.. and over night only lost 3%. I cant speak for "ROMS". I ALWAYS root and put on some ROM. But this time.. I am going to wait. Right NOW is AWESOME.
Trust me.. had a Google Pixel... duh had to give it to kid that moved.. to get a job at Microsoft.. YES. So all I was using was ZUK Z2..which had a AWESOME battery.. only go down 1%. Oh.. but the camera.. when I use the Note 5....WOW..
So..there are THINGS programs we ALL love to stick on.. SOME can be.. as in my case be the problem. Theres just no way those two programs in my eyes could effect the battery. But reset over and over.. putting them on then not.. They were the problem.

[Q] Samsung Galaxy Note critical battery life after 4.1.2 update

Hello!
I know that there were a lot said about battery problems in 4.1.2 android, but i still haven't found any solution on my problem. My Note was bought with GB 2.3.6 and had an awesome battery, but after i updated it to JB 4.1.2 (via Kies), suddenly battery life is catastrophic. I have everything off (bluetooth, wi-fi, gps), my screen brightness is on minimum, i use my phone on GSM band (not 4g), i also disabled some of unused apps, etc...everything said was also my practice on previous version 2.3.6 and phone battery lasts up to 4 days, but now, it drains off in 17hrs and I barely use my phone!
If I check battery stats, it shows that screen is the major consumer of battery and it seems like it is on all the time, although the phone screen is physically off most of the time. It means something causing my phone being awake all the time instead of being off.
Any ideas how to fix this??

4 days? really? think that is unheard of. Either how, it should last longer than 17 hours.
Try going back to factory settings, perhaps theres something running thats divided by zero :silly: .
If you feel adventurous you can also choose to root & try a custom rom. Though thats your responsibility and choice entirely.

Yup 4 days, not kiddin...4 days of average use.
I forgot to mention that i already did the factory reset and i also wipe the cache partition in recovery menu... I disabled practically everything, and i use things when i need, nothing is set on auto, sync or anything. Last night I didn't touch the phone for about 9 hrs and battery consumption was around 1% which is ok, but it's draining everytime i turn on the screen like 5% in 10mins. BBS shows that well known GTALK_ASYNC_CONN as a battery eater. Is it possible to kill this annoying thing on un-rooted phone???

[Q] Battery drain, cant find the cause!!

Gentleman, currently im having a big issue with my S3 Mini.
Some weeks ago, the battery started draining in a really short lapse of time. We are talking of aprox. 12 hourse of low usage (one phonecall, no sms, little whatsapp mesagging, some web sufring). By checking Betterbatterystats, i can confirm that almost 11 hours, the phone screen is off (or maybe 10 hours and a half).
I dont know what to do, i turned on airplane mode, and the problem persits. Changed rom 3 times (4.1.2 to 4.4, to 4.1.2 again), wiped data, cache, system, internal memory, etc..
Betterbatterystats screenshots are ATTACHED TO THE POST!!, to see if you cand find a wakelock, alarm, or something that can be interfering the battery life. (btw, i ruled out that theory since i changed rom and wiped everything so many times, but maybe there is something attached indefinetlely to the phone, really dont know).
The battery itself is the only reason in my mind right now, but the phone is only 9 months old (as well as the battery of course).
One thing that calls my attention, is that the charging time takes 2 hours max, maybe 1 hour and a half. Can the battery be damaged with so little lifetime?
Appreciate your help!!!

i can most certainly say that it's the battery, but don't run out buying a new one, yet. Wait 'till someone else confirms it
i had the same problem half a year ago (mine was also 8-9 months old back then). The phone started rebooting and many weird stuff happened I changed the battery and everything was ok. Now it's acting up again and i might change battery again.

Turn off wifi and reboot that helps sometimes . On the first Screenshot was your wifi always on. On the last Screenshot was your Android OS on the first place. That was the 1GHz bug.
facebook updates
Don't have facebook app (only messenger), and without messenger app, the battery keeps draining.
I red on the internet that the 1ghz bug tends to appear on Cyanogenmod. Only had cyanogenmod 11 for some days, turned back again to the stock rom.
Could this bug affect my phone right now? How can i fix it?
If not, im really thinking of buying a new battery, but the risk of another problem affecting the battery usage from the phone keeps turning me back!
Thanks!!

The battery don't seems to be neither round or thicker, and it don't spins freely.
Have you tried 'telling' the battery how much capacity it has again? (Drain until it automatically shuts down due to flat battery, charge back to 100% while off, switch on, drain again, charge again and use as normal)
Many manufacturers recommend charging when you reach 15-20% during normal use.
Also, have a look at govenors/schedulers if you have a custom ROM installed. Maybe changing combo works better for you, or even changing combo and switching back.

It won't harm your device. Would you mind sharing from where you're getting a 2000mah battery and if it's the same size as the 1500mah one from Samsung?

[Q] Battery Drain?

Hey Guys,
Just picked up note 4 and I've noticed a severe battery drain when using the phone.
On Devik, but only with 30m 33s of screen on time the battery is down to 86%.
I've been greenifying everything I can, but still a drain.
Wondering if anyone else is experiencing the same?

Only had the issue for the first few hours because of all the downloading it was doing and I wish pushing and pulling a lot from dropbox to my phone using astro. After all the crap was installed and done moving it went to a more normal level. Mine has been unplugged for about five hours now with about the same amount of screen time and a few calls and it's still at 87%.
I hope this doesn't turn out to be a real issue with the battery or anything.
I have actually noticed the same thing. I'm guessing that's why the international version of the phone got an update so quickly. Hopefully we get it as well, and it'll be in a flashable .zip
Update isn't due out until the global launch which is the 17th that's probably when it will be released. My battery has been amazing 2.5 hours screen time and only down 30% and I watched 2 hours of ESPN first take

thats good to know..
we all know there is no way to compare or even comment on battery useage the first week or so; it takes that long for the battery to "settle" in, and, of course, until you put the damn phone down for a few hours, which wont even happen the first week, you can't really know how the battery is..Plus, OF COURSE, since no two phones are used exactly the same way, with the exact same programs, the exact same push notifications, and the exact same programs starting up automatically, my battery stats really mean nothing to any one else...
that being said, I am sure there will be dozens of battery threads here within the first few days anyways..
Note 4 Battery Drain is real
All three people I know that have the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 and the person was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!

Note 4
I Had one Note 4, and I charged it twice a day, and not using too much from him.
On battery since 5am and I arrive at 5pm with less than 20%.
At the place that I bought they told me that they had changed some Note 4 to the iPhone 6 Plus because the same situation!
I changed mine too, I Love android, but there is too many problem with Android, and for know I will try one bigger iPhone!
At least this one works for two days...
I love the Note equipments, I had, note 2 Note 3, and Note 4, S2, S3, S4, S5 and too many problems with Samsung, tried LG, but I don't get used to the back keys...I need the front key like Samsung and iPhone to turn on the screen!
One thing that Samsung must to improve is the fingerprint, since the one implemented on the iPhone works way better!
The iOS is way limited, but works way smooth and fast with less hardware! Lets see if I get used to it this week, if not I will return to Note 4 even with that problem...but it is an annoying problem that Samsung should resolve as soon as possible!!!

G870A 5.0 battery drained in less than 1 day

I just got the AT&T update to 5.0 a few days ago, and the battery drain was incredibly fast, just like 8 hours when I first had it.
I did some checking around and finally did a factory reset from recovery, and that has helped a little. If I restart the device every few hours, it seems to help somehow...
But when I put it down at night, the battery drains down 50-60% in just the few 6 or 7 hours it lies there. I have tried apps like gsam and the stock usage monitor, and compared them to the process stats in developer mode, and come up with nothing. Most of the process stats are showing near or at 100%, by the way...
Another great side affect of the upgrade is now when I use Maps with location in high accuracy mode and hooked up to the charger, it gets really stupid hot. And it never used to do any of this before. Is this whole upgrade just a POS or is it just my device? i swear I used to get 2-3 days of battery before this. Help me save the upgrade before I roll it back to the old software, thanks.

Did you ota, or flash rooted 5.0? Sounds like a bad flash...if a factory reset didn't fix it I'd suggest downgrade back to ne4 and start fresh.
Mine and GF both g870a's and are running great on 5.0.
I took the OTA and then immediately did a factory reset.
I can't remember exactly, but also check that the OTA did not set GPS to auto update apps. I THINK it did on mine.
I'm also running great on 5.0 FYI

I checked that and it wasn't the problem. I think I pinpointed the issue... I tried running in safe mode for a day with a small improvement, but not much.
Then I went back to normal mode and deleted each app separately and after three deletes, I got rid of the Weatherbug app and all is apparently better. I found some others posts on this forum regarding this app causing problems after an upgrade as well...
Any thoughts? I kinda liked that app.

Although I like the tablet UI for this app much better...I've been running with the Weather Channel app for the last year...using static locations and not using MPoints. I am totally opposed to installing anything with Weather Bug in the name due to the amount of malware and ineffiencies found on PC versions of that app. I've forcibly removed and cleansed it from many a friends PC/laptops. YMMV.
Sent from my SAMSUNG-SM-G900A using the XDA mobile app
Now, a few days in, I can completely confirm it was the WeatherBug app. I have had three days without a charge (now sitting at 13%!) and it looks like it could go 5 without much use.
I am scared to try another weather app, but I'm gonna try the weather underground thing...

5.1.1 Battery Drain

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.

Or it's something to do with the AT&T version of the firmware as yours is an international version and not having issues.

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.
