Please help....
I have read many threads about this, but I don't understand any of them. My battery life is horrible, I am only using it for the occasional phone call, texting and checking my email. It's very frustrating because when I need to use it, the battery is dead (or almost dead and I can't use the camera).
I don't understand all the lingo on here about what version "this" and "that" everyone is using. Downloading certain apps to fix this.....
I'm not very techy and just use my phone for basic things.
PLEASE HELP!!!!
Suggestions:
Turn off bluetooth until you need it, then turn off when done.
Turn off GPS until you need it, then turn off when done.
Turn screen brightness to automatic or lowest setting (your preference).
Turn off 4G receiver if you are out of range or just don't have 4G coverage in your area.
Turn off synchronization if you don't care for email, Facebook, Twitter, etc updates. (Not really necessary if your update interval isn't set for short intervals.)
Utilize Wifi as much as possible, if that is an option available to you. BUT turn it off when you know you will be out of range for a good bit of time.
Toggle Airplane mode after each phone reboot. (Stupid bug)
Utilize the TouchWiz program manager (long press on home screen and under Samsung widgets).
Kill the OmaDrmConfigService process via Settings > Applications > Running Services. (This appears again with each phone reboot, unless you find a process killer application in the market.)
If you use Wifi a good bit, it's a good idea to set your Wifi sleep policy to "Never". You can access this via Settings > Wireless & Networks > Wifi Settings: Press menu and select Advanced > Wifi Sleep Policy. Setting to never will not revert back to 3G when you turn off your phone's display as long as wifi is still turned on and within that connected wifi signal range.
If you still get **** battery life, then you can download Spare Parts or BatteryHistory from the market. BatteryHistory is a ripped out piece from Spare Parts, which is really all you need to diagnose your issue.
OR if you don't want to install anything you can key in via the dialer: *#4636*1111# to get to the same menu that both programs above display. (The menu is labeled Battery History.)
From another battery thread that pertains to the two aforementioned programs:

What you do is when you notice that it's doubled on the top drop down box that says "other usage" click on that and change it to "partial wake usage" and anything listed under there is keeping your phone awake. See what is continually running.

Dont ask me to explain this just try it. Use astro and delete the android folder at the root of your sd card and reboot

Did deleting the android folder work or anyone else? I'm trying to see how that can help but if it does good find.
I have no ideawhy but after flashing a few times testing themes on dk28 my battery tanks and my gallery gets slow. The album thumb folder inside there is what fixes the gallery so I usually delete it but I got lazy and deleted my whole folder since it regenerates on boot and my battery came back. Ben deleting it since lol but I flash a lot

Not certain how it helped your battery issue, but good to have that knowledge. I sifted through my folder and only saw cache files for what looked like thumbnails.

Try this:
-Toggle airplane mode every time you reboot. You probably have a "time without signal" of over 50% if you look in settings. Toggling airplane mode resets the radio and so it doesn't keep looking for signal unnecessarily which kills battery
-Gps on doesn't drain battery, only when its being used by an app
-Turn off background data and auto sync. If you don't have facebook/twitter widgets or care about email push notifications then save some power and switch it off.
-Check for apps that aren't letting the phone sleep. Download "spare parts" and it should show you.
-I'm guessing you have the updated Facebook app with chat. I would suggest going offline in chat because it doesn't let the phone sleep and will drain your battery really fast.

Hi I'm having a bad battery drain from android system. I'm assuming it's a wake lock but I can't figure it out by looking at better battery stats so if someone cud remind me the adb command to pull the history and take a look at it if really appreciate it.

What I found about this problem on my GS3 is that this happen when I use Google maps and Navigation. It seems to keep the location services even when application is closed. I was able to reproduce this 3 times now. The way to fixed is to go to all applications find the Maps then remove all updates and then try to Disable the application then reboot ( you can't completely disable the Maps because is considering a system apps and after the reboot will start again but you can do the same thing one more time or until android system change to system from Gsiff_daemon or gone as aprocess). Then you can install again Google maps updates. Eventually will happen again but let's hope for update from Samsung or Google maps.
Here is the solution if you want to delete Gsiff_daemon file since you are rooted. To see if you have this problem hit the reflesh button on your battery summary screen:

Also here is the whole tread about Gsiff_daemon problem:

IN RELATION TO GSIFF_DAEMON
do any of you guys have the "increase volume in pocket" setting on in phone-->settings?
also do any of you have motion settings enabled and/or autorotation on?
Seems it has to do with the gyro issue
also are you guys rooted or non-rooted?

Jellybean didn’t solve it. Gsiff_daemon just popped up for me. Just renamed it AGAIN.
Hopefully it won't pop up again

Bad android system battery drain
Hey guys,
so if nobody found the solution yet to this problem, i have a possible one. I researched all day today about this problem and decided to start testing things. After doing a few tests, my battery at the moment is doing great. Its estimated time remaining on standby is 12 days. its kinda crazy lol.
anyways so I took off my LTE network and just set it to regular GSM or CDMA (depending on your provider, mine was CDMA) in Settings > More settings > mobile networks > network mode.
I also went into Settings > Application Manager. Scrolled towards the right to the 'All' tab. Went into the apps I dont use and unchecked 'show notifications' box, and also cleared cache. Also, I disabled Samsung Account, Samsung Backup Provider, and Samsung Cloud Data relay.
Then after that, I went to Settings > Backup and reset , and I unchecked Backup my data, and automatic restore.
I'm still testing. My wakelocks are still really really high. About 130/hour. I'll let you guys know more if I find anything else.
UPDATE: I let my S3 sit on my night table all night unplugged. The battery went from 95% to 91%. My android system went from
35-45% usage down to 6-8%. average 0.5%/hour battery drain in standby. Android system is still giving me wakelocks though, approx.
60/hour in standby. But when I checked betterbatterystats, the deep sleep was activated the whole time, and not partially wakelocked.
I really hope this helps you guys. Ill try turning on some of the apps today to try and pinpoint exactly where this battery drain is coming
from.

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.

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.

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.
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.

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.

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.

Hello guys, i just found the solution for the problem! This works to every phone, no need to root or unlock bootloader!!
Just follow the following steps:
1) Open Dialer app
2) Type the hidden menu code. For example, h815 international model: *#546368#*815#

3) You will see the following 4 options: Device Test, ELT Test, SVC Menu, Field Test
You select SVC Menu
4) Then you select Log Service
5) You will see that the Kernel log will be enabled and all the other options disabled. On my stock LG G3, i checked the same options and all was disabled from the day i have it.
So disable kernel log and check the others too! Everything has to be DISABLED
6) Exit the hidden menus and reboot your phone. After that if you check your stats with an app like GSAM you'll see that ''logd'' process is going down to 0%! (Check the picture below for proof!)
If this helped you, press the Thanks! button :good:
just a heads up for those who are voting , you should go through a few battery cycles before noticing if the battery life has improved or not , voting few minutes or hours after applying the fix is not accurate
AT&T Android V6.0
If you're on Marshmallow using an AT&T LG4, it appears that you can also kill "logd" by using the settings menu. Go to settings > general > about phone and uncheck Activity logs. That seems to have disabled the "logd" functionality on my G4. When I opened the Service Menu using the code *#546368#*810# as posted in #1, all the log activities were disabled.
My battery life has improved somewhat, but it still isn't great. At least now "logd" isn't at the top of the list for battery usage!!
My phone is totally stock, with developer option enabled.
Hope this helps.

I made this change about 10 days ago. I've gone through 7 charging cycles since then, so I think the general battery life trend is going to be representative going forward. At first I noticed a significant change. I could get through a day with about 1/2 - 1/3 battery left. Much better than before where I'd be a 10% by 7:00pm. Now, I see about 1-2% battery drain per hour. The phone never seems to go into deep sleep, even at night when I leave it on, based on battery stats.
My usage profile is about average. I use the phone for business, so lots of email, SMS and Skype. Bluetooth is on all the time for my smartwatch as is WiFi.
IMHO, I don't believe the Marshmallow (V6.0) battery life on is nearly as good as it was on Lollipop on this phone. Hoping it gets better with another update....

any other app or process that prevent your device to go into deep sleep maybe ? apart from logd of course
@touns_j
Haven't found one yet. The #1 on the battery usage is "Screen" at the moment. Will need to do more investigation.
No luck man. logd is still active after disabling everything from service menu. I am at second charge already.

Check again the settings guys make sure all is disabled. Also you need to disable activity logs option from About Phone in settings. Then reboot. I don't know guys but for me that worked. 3rd day now and my battery is better than ever. Also logd usage is at 0%

Al is set. Do you use the phone on wifi? As on wifi i saw a small logd usage, but on 4g i have again high usage from logd.

I'm most on Wi-Fi but I use some data also during the day. Good usage there also

I some how feel that GSAM triggers the logd process. Can't confirm but I find G4 battery performs better in absence of GSAM battery app.
I also thought of it... I am wondering whether logd appears in any other battery stats apps.

On my unrooted H-811 all logs were disabled by default:
I disable log in phone info and even in the hidden menu provided here but logd is always there and waster more than 10%. Is onl root my chance?

Thanks I will give this a try
This definitely worked on 3g connection. However yesterday upgraded to 4g Sim and the logd process again shows up on the gsam stats. How can we solve this?

I've contacted Lg about it. Took 10 days for a reply and it seems I have to go through a tedious process. I was asked to try safe mode despite explaining it's not a specific app. I did it anyway and of course battery life was better because I had hardly any apps running but it was only about 10%. If I find out anything useful from LG I'll let you know but it looks like they're either unaware or don't care.
