13% is ODD. Something is sucking up your battery.
Expand your Android system and post the Screenshot - want to look at cpu wake time.
What is your setting under - Advanced Wifi options - while asleep - wifi on or off ?

To be honest I have done so many tweaks to help with wakelocks. It is definately not an app but the standby time is sooo much worse on my Note in comparision to my HTC One S. I'll get about a day regardless of screen time. On my One S I'll get 2 days with the same screen time and with the same apps.
The only thing I can think of it being is that mdm_hsic kernel wakelock. Have no clue what to do about that though, and it's clearly a Samsung/Note 2 bug given that the HTC doesn't have this sucking away the standby time.

Do you have ebay app installed?
Try uninstalling and see if this makes a difference. The ebay process/service constantly runs in background even tho its disabled in app settings and doesn't show battery usage.
I had same problem and found that its to blame!

The thing is, I also have the ebay app on my HTC and it doesn't suffer from this problem. The HTC is 4.1.1 though so I'm guessing this is either a Samsung problem or a 4.1.2 problem.

hi,just a few pointers to think about ....?
i am on stock 4.1.2 not rooted ,and my avarage battery drain overnight (10/11 hrs +) is 2%..or ..3 %.
i also have a note8.0 and battery drain is normally 1% in standby mode overnight (10/11 hrs )also on 4.1.2
lucky ? no i don't think so .
(maybe i got my all "tweaks " right..no ?)
just a few pointers (things to think about, why others get better results and others not,in this case on 4.1.2 )
good luck

Do you have any Battery manager apps installed? I had one that constantly pulled WiFi status and since I have WiFi disabled when outside of home or work it kept on turning it on/off and drained my battery. It was my error for configuring it wrongly, I admit but still, that may happen without control.
Check Wakelock Detector, click on this:
Awake.............................Statistics since..............................Deep sleep
bar after night of rest and post statistics that you find there, The most interesting is a difference between Screen-on and awake times. If your phone is awake much longer than it has it's screen on then there are some processes that keep it awake and drain battery.

Wifi does seem to be messed up on this phone. I find, on standby, it causes more drain than 3G does. Usually something like 10% - 15% overnight.
This is not right and something is seriously a miss with Samsung. My HTC running the exact same apps does not have this problem. You shouldn't have to turn wifi off as opposed to 3G to get better battery life.

Are you thinking about some hardware problem that causes wifi to use more memory than usual? Like higher voltage or something? Because that is not very probable. I think there is some app there that is using wifi, high power usage happens when wifi is performing scans is being turned on or actively transmiting data. Please use wakelog detector to find what app is causing kernel wakelocks and from there we can find a real culprit.
I does not have to be malicious but may be an incompatibility between hardware and some software, one that works well on HTC and not on this Samsung model.

No I don't think it's hardware.
I also don't think it is an app given what I have observed with wakelocks and deep sleep. I have made many adjustments to the phone and I'm clued up with wakelocks and the like and this doesn't seem to be a wakelock issue.
I have even assigned a static ip and made tweaks within my router but it hasn't helped. There seems to be a strange way this phone handles wifi and it is causing unnecessary drain.
In regards to Kernel wakelocks, it would appear something called mdm_hsic is causing lots of wakeups and more standby drain than it should be and this does not feature at all on my HTC. This is not related to wifi, but I'm pinning the general crappy standy drain im getting on this but there doesn't seem to be a way to get rid of it.

mdm_hsic is related to Modem part, you may try different modems (be mindfull of efs problem in newer firmwares), also try to enable/disable "fast dormancy". I think you could test that by selecting "GSM only" and observing.

I have tried different radios in the past. If that's what you mean?
I've also tested around with fast dormancy (it is currently disabled)
My network only works on 3G and has no 2G coverage. It is purely a 3G network and therefore GSM only will not work. This problem still persisted when I was on a different network though and selected gsm only fornthe majority of the time.

Yes, I was talking about radios.
Have you ever tried changing CSC file? Full, four part flash in Odin, not only PDA?
What method did you use for modifying fast dormancy setting? Because the correct one includes full factory reset when changing CSC. Anyway fast dormancy would be a problem only if you used 3G network for data.

Nope have not tried changing the CSC.
The method I used for fastdormancy was with that app in the marketplace than allows you to toggle it on and off. I'm not sure if fastdormancy is linked the mdm_hsic though, to be honest.

Which stock ICS are you running? Do you have wind kernel installed? Download and run better battery stats to see what wake locks you have. In regards to Fast Dormancy disabling it will either give you better or worse battery life. What is it? Its a tech used by the phone company to save battery power by putting the phone's radio in a low power state yet never relinquishing the data connection, so when you wake up your phone it doesn't have to spend the 3-5 sec reestablishing the data connection. The phone's software works hand in hand with this, however if your phone co in your area doesn't support it the phone's software will never let it sleep, therefore disabling fast dormancy will improve battery life. However if you have it disabled and your area supports it your data connection will never be released and therefore your phone's radio will never be shut off using battery. On top of that this is only a function of an HSPA/3G coverage area. With 2g (edge) or LTE its meaningless. Two more suggestions:
1. Power off the phone and remove the battery for 30 sec - 1 min. Then reassemble and power back on. For some reason this will fix the deep sleep suspend wake lock.
2. If you are rooted and have cwm installed, boot your phone into recovery. Create a backup. Reformat the system and data partitions. Reinstall your ROM, then go to restore/backup and select advanced restore. Select data then the backup just done. After complete reboot.
Good luck.

Unfortunately No. Battery still drains 7%+ per hour on mobile network. On wifi, it's 1%. I have turn on Fast Dormancy just for the sake of it. Maybe need to move to CM 10.1. However, I play games on the phone sometimes and enjoy the snappy response of ICS.
I've been having problems with battery drain, from 6-7% an hour to more than 15% with the latest CM RC.
Changed over to Pac Rom, seems to be a lot better for battery power so far but a bit laggy.

Disable syncing.
Make sure you are not using LG supplied weather app widget bad power hog.
If disabling Sync works but you still need to get things like email notifications try using DS battery saver from the play store.

Try this:

Wireless & Network: Select MORE
Select MOBILE NETWORK
Select NETWORK MODE

This will turn LTE off and should fix you issue, in most instances HSPA+ (4G on AT&T) download speeds are just as fast as LTE without the power issues.

In the past I had issues with the whatsapp creating wake locks. Now this goes back to last year but I stopped using that app because of those issues. Try freezing it and reboot. Also when is the last time you calibrated your battery? Just in case you don't know: charge to 100%, while still plugged in reboot into recovery and wipe battery stats, then reboot your phone and unplug. Keep your phone off the charger till the battery goes dead and the phone powers down on its own. Then charge to 100% with the phone off. Also I think I asked this before which version of v20 are you running?

hey guys...
i have tried everything to stop the battery drain
switched to many different roms
under-clocked processor to 768mhz
set a black wallpaper
brightness set to minimal
did battery calibration
switched of all background processes and made sure no location seeking programs works.
used CPU spy, the cell does go to deep sleep
tried juice defender and deep sleep battery saver
but nothing seemed to work
phone locked on full charge drains 40 to 50% in night without using.
then after a few days later i restored everything and opened airplane mode and I went to sleep, in the morning the battery didn't went low a single percent. battery health is good as works really well on airplane mode.
i have low signal issues but i get text msgs and calls with no problems at all, and my explorer and s3 seems to perform well
my all type pf connectivity is off example: location access WiFi Bluetooth etc only gsm is working, i manually selected the network and set it to gsm only rather them auto from *#*#4636#*#*.
what shall i do??
i searched and tried many things from the internet.
i really want those calls i cant always be on airplane mode, the problem is 200% of the antenna draining juice to get more signals. please help.
is there any way to stop the battery drain or restricting the antenna to consume less juice?
PS:using cm10.1 by nightly version:19 Aug 13.
anyone??
one thing more i installed better battery stats it says
no or unknown signal
no data connection
and it is running continuously like since i installed betterbatterystats.
where can i get this bug?? or disable this service??
please give a detailed explanation.
There are a few good apps to try I use

Battery drain
I´m having same problems with my DHD, currently im using 4.2.2 Samsation (was it named like that but anyways 4.2.2). Without using phone it still drains 40% in few hours.. I got replacement battery from eBay and thought that would help but didnt help at all. I´ve tried different roms but would like to have newest roms without battery draining so much, so could someone share how to get it better?
And about changing radio, was there a possibility that you may brick ur device if installing wrong radio?
Thanks already!

yup there was nothing, no wakelocks etc i even underclocked my processor to 768mhz... the thing is the signal reception cause when i turn the cell in airplane mode and leave it over night the battery doesnt goes down a single percent. it acts solid.
i get around 18 asu signals at my place i check it from *#*#4636#*#*
but the thing is i was using an HTC explorer before switching to desire hd and with the gsm mode(no airplane mode) the battry stayed solid like the desire hd one with airplane mode(didnt dropped a single percent) at the same house same place.

Hi guys
I have a LTE Note II and have had this battery drain on standby where wifi will absolutely destroy my battery. This has been going on for months and months and I'm just not sure if Samsung are ever going to resolve this and it is quite the pain in the arse.
I've done many tweaks to my phone, and all location services are off. Also, I've set it as a static IP, but nothing seems to help. I think this is related to the wlan_rx_wake wakelock? I get the impression my phone is responding to the wifi and getting woken up constantly.
Does anyone else experience this and do you have any suggestions?
P.S. please don't mention my apps causing it. It definitely is not. I know my way around Android and also, my Nexus 4 with the same setup (but location + google now turned ON) absolutely annihilates my Note II battery life on standby. This is clearly a Samsung problem that they have ignored for the best part of a whole year, and it seems to be related to wifi.
Any help would be greatly appreciated.
Thanks

No exact figures but I have been observing it for months now and it hasn't been the case with any other phone I use. With wifi on, it'll drain around 20% overnight. With Wifi off, it'll drain 5 or so %. With Wifi on on every other phone I own/owned, it will barely drain at all overnight.

Stock ROM. And yeah, but it is constantly being woken up.
Sorry for the bump, but this hasn't changed.
I'm not sure if this is to do with just the N7105, but it is something that just won't go away. I'm now finding I lose between 20 and 30% overnight (around 7 hours) with wifi on, or about 10% with data on. With these both turned off but the phone radio still being on, it only drops about 2% in the same time. This was tested with bluetooth/gps and sync turned off.
I don't really have the time to write up everything that I have tried, but suffice to say I have tweaked the phone a lot over the past few months trying to sort this out, but nothing works.
Here is a quick summary of the stuff I have done.
Firstly, I have to run a stock rom and kernel because there is an app I need that will not work on custom roms/kernels. It also doesn't work on root but I have found a procedure to toggle unroot/root when need be and it works fine. Therefore I'm stuck on 4.1.2 as I want to be rooted but I cannot use any custom rom or kernels.
I have tried factory wiping the phone/installing later versions of 4.1.2, etc etc and the same problems still exists with a freshly wiped phone and no apps installed. This problem also doesn't happen with my Nexus 4 or any other phone I have owned with the same setup, so I am very certain it is not due to a misbehaving app.
I have frozen a lot of bloat with titanium backup, I have hibernated a hell of a lot of stuff with greenify (including system app where there are no perceivable negative consequences)
I have added a few tweaks to the build.prop such as to disable fast dormancy and a few other supposed power saving ones which are meant to help with the msm_hsic wakelock.
There are many other things such as setting a static IP, and also tweaking with my router based on some advise I found on these forums. Nothing much has helped.
Location services and google now are off, and I'm not using the Samsung bloatware apps.
I use betterbatterystats and the partial wakelocks are fine. Very low infact.
However, IMO it is two "kernal wakelocks" which are causing me the problem.
wlan_rx_wake - in regards to the wifi
mdm_hsic_pm0 - in regards to the data
These are by no means outrageously high. My estimation is perhaps 10 mins wake up time and around 2000 "expire time" (whatever that means) every 3 hours or so. However, these two are always the highest kernel wakelock depending on if i'm using wifi (wlan_rx_wake) or data (mdm_hsic_pm0). My phone is also not being kept awake too long too in general.. at a guess around 3 hours awake time for every 2 hours screen on time for every 15-20 hours.
I can't remember if these kernel wakelocks were super duper high in the past, and the fixes I tried actually lowered them, but I still notice this massive Idle drain when on data or wifi (just over 1% per hour - or 2-3% per hour respectively).
In regards to the Wifi.. I suspect that packets are being sent from my router which are constantly waking up my phone. Unfortunately, I haven't been able to solve this problem with any of the router-side fixes I've tried.
This leads me to suspect that the wifi and data radio of the N7105 is power hungry, or I've had a faulty unit since day one. I keep hearing about this stellar battery life for this phone but, for me, the best I've ever got is around 20 hours. This may sound good but the problem is it is 20 hours with 6 hours screen on time, or 20 hours with 2 hours screen on time. This doesn't seem to make a difference where I should be getting two days when I only have 2 hours screen on time.
Any help would be greatly appreciated, and any experiances of others with the N7105 may help find out if it indeed is more power hungry. I'd also like to add that my network does not support 4G yet so this is all on 3G and NOT LTE.
Thank you, and sorry for such a long post.

Hi guys
I have a LTE Note II and have had this battery drain on standby where wifi will absolutely destroy my battery. This has been going on for months and months and I'm just not sure if Samsung are ever going to resolve this and it is quite the pain in the arse.
I've done many tweaks to my phone, and all location services are off. Also, I've set it as a static IP, but nothing seems to help. I think this is related to the wlan_rx_wake wakelock? I get the impression my phone is responding to the wifi and getting woken up constantly.
Does anyone else experience this and do you have any suggestions?
P.S. please don't mention my apps causing it. It definitely is not. I know my way around Android and also, my Nexus 4 with the same setup (but location + google now turned ON) absolutely annihilates my Note II battery life on standby. This is clearly a Samsung problem that they have ignored for the best part of a whole year, and it seems to be related to wifi.
Any help would be greatly appreciated.
Thanks

I ain't expert...
but, I would suggest like this :
Go to wifi, press menu and then Advanced (advanced setting of the wifi).
uncheck/untick "Scanning always available"
"Keep wifi on during sleep" = set to Never.
uncheck / untick "auto network switch btwen wifi network and mobile networks"
all these helps me to minimize the usage of wifi during night times (when I sleep). Anyway, device also need to have a deepsleep
Hope can help you as well.

I've noticed lately my battery life has plummeted. When I get to work, I turn off wifi, and even after very light use throughout the day, 9-10 hours later it will be giving me the low battery warning. I checked the Battery screen, and noticed the Wifi bar is solid blue the whole day as seen in the attached picture. If I am reading this screen correctly, wouldn't that be an indication that wifi is actually on all day? As you can also see in the screenshot, the wifi logo is not on at the top, showing I do in fact have it turned off. Do I have a problem? Does anyone else know about this issue and have a fix for it, if it is in fact a "issue"?
Go in to your WiFi settings, hit your menu button and hit advanced. Uncheck "always allow scanning"

Thanks, doing that this morning and will check the battery screen in a couple hours.
OK, that seems to have taken care of the wifi appearing to be on in the battery stats. I will wait until later today to determine if that was the cause of my battery draining quicker. I know there were a few new apps I installed around the same time, and I may have to start digging through those too.

Are u in an area that has low lte strength. If its switching between LTE and hspa+ that is tough on battery. Or location settings, or random apps running in the background. Grab BBS and see what is eating up the battery, wake locks apps etc. Their is am Xposed module that dispatches of wake locks if that is your issue. But I'm guessing its one of your apps or signal.

Actually, yes. When in my office, I get VERY low signal and it is constantly in HSPA. Also, what is the full name of BBS? I am not finding any kind of tool just searching play store for BBS.

Better battery stats is what you are looking for I believe.

Yup, found another battery thread on it. I downloaded it, but am not rooted, so not sure how helpful it will be. All the other data is greek to me on it, so someone have any pointers what to specifically look for?

Go in to your mobile network settings and change the network mode to wcdma/GSM instead of lte/wcdma/GSM if you're always switching between lte and 4g. Try that at least.

if possible grab WiFi at work, and use only that and I bet your battery significantly improves. then when u leave, hop back on normal data and see if that helps
Well, I've tried the setting the mode to not include lte, still getting pretty quick battery drain. There is no usable wifi here due to the level of security my facility enforces. Anything I can have BBS export to have you fine folks take a gander at and see if you find anything relevant?
My battery drains around 1.5% per hour even after turning off AOD and wake screen for notifications setting. When those settings were on, it was draining 3-4% per hour. Has anyone else noticed the same? Any suggestions to improve the standby drain?
Are these numbers with WiFi and mobile data on? Airplane mode off?
Wifi on. Data off. Airplane mode off.
I'm using a different ROM but I've experienced similar numbers. It's obviously better with WiFi off but that's possibly not the point
Disable battery scenarios , worked for me

No, other way around.
Being connected to a Wi-Fi is more efficient than Mobile Data Connectivity.

You could check the Running Services in Developer Options, and see what's running in the background.

I can't find the option in developer options. I think it has been removed.

Will check tonight
under the battery or 3rd party like accubattery should show you what's draining it , Im on the EU weekly and have no such problems
You could try a Custom Kernel like Nexus Kernel
NotZeetaa, the dev behind Nexus Kernel also made a Magisk Module "BatterySaverMod v1.2" that can be found in the Nexus Telegram Group, which limits performance a little bit but reduces Power-consumption for active drain.
You could check with Activity Launcher from Play Store, if the settings-page "Running Services" still exists but may just be unlinked from Settings-GUI.
For me 5g stopped work since 13.0.7
I'm also experience battery drain in 13.0.9 and occasionally network failures. Many times calls ended and receive the message "network not availabe". I've done a factory reset. Will have to do it again
Till this rom have everything work perfectly
I used better battery stats and it showed that wifi had a lot of wakelocks and was preventing the phone from entering deep sleep. I turned off wifi and standby drain went to around 0.5% per hour. I think voice over wifi is the culprit here. I will observe the drain tonight with VoWifi off.

5g is pretty much useless anyway unless youre downloading very large files. It uses a lot of battery and makes the phone warm as well. I would suggest setting the preferred network type to 4g as it is more than enough for everyday use and saves battery as well.
You guys could use "Naptime" from Play Store. It supports ADB or Root.
