Since upgrading to KitKat (4.4.2) using the Google factory image and the flash-all I have had horrendous battery life. I've gone from 24-36 hours of battery to about 5-6 hours and I'm a fairly minimal user.
The drain seems to be coming from Android OS, in particular the Keep Awake is often 1-3 hours. After reading about others with the problem I did a factory reset and this seemed to resolve the issue but it's come back again. It's funny because it's fine at home, I've gone most of Christmas with no problems. Then I've come back to work and straight away my battery is getting kaned again.
I can't look for wakelocks because I'm not rooted and don't want to root. However I've tried experimenting by turning off location services, turning off wifi, and finally I've turned data off and this has done the trick. I'm wondering if it is something to do with 3g because I don't have any problem when on wifi at home.
The only thing I'm wondering is if I've got the right version of the radio, I had some problems when I was flashing so I did it again, everything seems fine but is there any way to tell if I've got the right radio rom?
Thanks in advance
Nick.
If you're data signal is weak it would use more power then say a good signal. Try using 2g only and see if that's any better.
How did you flash via adb I presume or OTA . Did you not flash the latest radio.
The end of your baseband number in settings will tell you what radical you're on , latest I believe is 98.

Thanks for suggestion but where I am sat has excellent signal (green in the mobile network signal under battery stats), I'm in the city centre sat in exactly the same spot I have been in for the last 18 months. This only started happening immediately after the 'upgrade' to KitKat.
I flashed using adb with the phone in fastboot. I did it like this to get a clean install because I've previously rooted the phone and I was having issues with the OTA update.
My baseband version is M9615A-CEFWMAZM-2.0.1700.98, is this correct?
As I've said previously I do not wish to root the phone again. It's possible this is not necessarily 3g, it might just be one of the apps having a wakelock but it becomes more evident on a 3g connection.
Is there any way I can get to the bottom of a wakelock on KitKat witout root?
The best way would probably be to uninstall each app one by one until you find the culprit , without root thought any game progress e.t.c will be lost unless it can be saved.
Checking only the apps that require data like Facebook e.t.c. will speed things up a bit.
Is anything showing under the inbuilt battery app ?.
Sorry but that's all I can think of , maybe someone with more knowledge can help. J

This was a problem for me when when stocked and unrooted, and without root you can not determine the real problem because battery stats will not be detailed enough. But problem is probably msm_hsic_host or something like that which is consume battery when phone is in sleep and even data is off. Actually some app is requesting data (which is off) and 3g modem keeps phone awake. My advice will be, fully charge your phone, from setting select 2g connection, data disabled(auto sync also), reboot your phone if battery is lower than %100 charge again and use it or do this before bed and sleep . Your problem would be solved for this condition. Some say google adressed this issue in 4.3 and 4.4 but I think it is still there for some reasons. BTW use 3g network only for internet otherwise it is just a battery drain, you gain nothing in terms of talk quality(and swithching between 2g and 3g is really painful). I solve my problem by rooting and install xposed framework and install gravity box and use status bar switches to change between 2g and 3g and believe me it is wonderful(no ART unfortunately). I know I talked too much but mai problem is probably 3g modem and you need root to solve it

Bende de var vallahi aynı sorun ama 2gde ve kernelliyim.Dur bir soriyim yabancılar.
İ have the same issue too,only with some minor differences,such as im always using 2g,im rooted,at the stock rom and also have a franco kernel installed on N4.What can i do sometimes?
4636v2 app from the play store will allow you to switch 2g / 3g without root. In fact there's quite a few apps that do that no need for exposed or root if that's the way you want to go.

I'm running lollipop on my n910c and having problems with battery drain when using mobile data. I didn't have this issue when on kitkat. Leaving mobile data on, even when not using the phone, seems that many apps that use the internet keep draining battery non stop. This doesnt happen when connected on WiFi.
Apps or processes like Google services, Samsung push service, even whatsapp and viber show up in the battery ussage when phone has been not in use most of the time. None of these show when using wifi and the difference in battery drain is huge.
Right now i dont have screenshots but will upload when possible.
I used to keep my mobile data always on. Now only when i really need it.
A friend of mine has an S5 and has the exact same issue after upgrading to lollipop.
Has anyone found a fix for this or am i doing something wrong?
Sorry for long post but i hope to find a solution which may help anyone with this problem and I think there are a lot of them.
I've tried using @MrColdbirds unofficial CM13. I'm still not allowed to post to the relevant forum so please bear with...
Whilst great respect is due for his work on this, I'm getting absolute garbage battery stats. I've flashed all of the required files, the updated firmware etc and have seen the battery prediction, even when not using the phone, decrease by roughly 100% compared to standard cos 12.1.
Many others claim fantastic battery life on the CM 13 and I'm wondering if anyone else has similar findings?
Of note was the fact that WiFi was way higher on the battery usage than anything else, like the WiFi wouldn't sleep even when phone sleeping.
I can't find anything obviously wrong as all settings were as per cos12.1 as far as WiFi sleep settings etc are concerned.
Anyone had similar, suggestions as to what I'm doing to get half battery life I'm used to?
I have marvelous battery life with the ROM, so I would assume it's some app that has a WiFi lock enabled that keeps the thing running. Could you post a wakelock detector log and maybe list your installed apps?
It seems to have settled down now. The screen on time also showed as 0% regardless of how long it had been used. Battery prediction now gone up to 1 day 1_23 hours as per cos ROM and deep sleep now fine.
Whatever had caused it may have been solved, a reflash was done.
Should it return I'll post a wakelock log but as of now thanks for your help but it has settled down for now.
Keep up this amazing work, many thanks.
Just realised the reflash was to latest build and as per your release notes I didn't flash the fingerprint reader packages. Without anything else changing I'd suspect my issues were around the fingerprint reader as others have also mentioned WiFi issues when the fingerprint reader package is installed.
Whatever, the latest setup running smooth and battery back to longevity.
I use unofficial and have a long battery life.
Hi,
Recently upgraded a T-Mobile HU carrier locked device to Marshmallow. Ever since the calls/cell standby is on the top of the battery usage list; the cell standby with around 12-14%, and the calls go up to 50%ish depending on the amount of calls. Tried to read up and saw a couple of suggestions like disable VoLTE, Wifi calls, but none of them are in the menu (see screenshots). Also found the suggestions about clearing the cache, did that one yesterday, now it seems a bit better regarding drain during sleep (only lost 9% overnight opposed to 20% earlier), but the cell standby still on the top of the list (see screenshot) with good signal. Is there any possibility to check for these options without breaking the warranty (so preferrably without rooting/custom rom etc)?

Hello,
I am experiencing exactly the same problem with my G928F. I have tried to flash several Marshmallow ROMs yet the issue persists.
The moment I switch to mobile data the Cell Standby drain begins. At the end of the day I barely have 20 % battery left with cell standby on top.
However when I use the WiFi(which disables the mobile data) the battery life is a lot better and I end up with more then 50 % at the end of the day.
I guess there are some problems with the radio/software in that Marshmallow. If that continues I will try to roll back to Lollipop.
Hi there,
Thanks for the feedback. Altho I must admit that since I upgraded to MM, if I dont touch my phone at all (mobile, wifi, bluetooth all turned on), battery holds in standby for 4 days, whats not bad. But if I dont do anything that should drain the battery like web browsing, video watching or games (what I dont do anyways), just do some calls during the day, the battery drops like hell, I'm on 20% by the evening. Cellular service stuff should consume much less battery in my opinion...
best,

Same issue, On the three network
Same problem here. Cell Standby is on top.
Anyone got any fix to this?
I have contacted Samsung Support and they told me to send the phone to their repair shop.. WTF ? I am sure that is a software issue as it is not only my phone and I doubt they are going to fix it. They will just waste my time...
One more: same problem for me (using TIM in Italy with an unbranded device). I will try keeping the wifi connection on (I usually don't use the wifi connection in my office) just to check if even for me this is the main cause of the battery drain I'm experiencing with Marshmallow! I'm currently using the French stock ROM (PC3) which seems to be the most recent version, but still experiencing short battery life

Of course it is not a device hardware problem, given that with Lollipop for all of us it was not like this!
I have the same issue, I simply turn DATA off to get rid of "cell standby drain". I use "wifi" most of the times (office and home) for my data usage, only switch on network data if I am out and just to check for updates and disable it in a minute or so.
Have somebody tried the new UK version rel. PDA PD2?
Just released last night...
Might this new release have sorted out this battery drain issue?

Same problem here, Optus in Australia. No 4G connectivity, massive battery drain (only when not on wifi). What I have discovered is that the mobile network is continually disconnecting and re-connecting and that is pretty much sucking the battery aswell as rendering data on the phone useless. It cannot connect to 4g, even if the signal strength is 100%. SMS take a long time to send (i guess they go in teh short time it connects. Phone calls either fail competely or like yesterday I had one where I could hear them but they couldn't hear me.
I went into an Optus store, but of course they just want to sell phones. They said I could put it in to them under warranty and would be without a phone for 10 days+! Or could go to Samsung store, which I have an appointment for tomorrow. I don't hold out much hope on that.
Custom firmware is not an option as I need to be able to connect to my work WiFi and that uses vmware air-watch and it doesn't work with rooted devices or custom roms.
Is there a way to rollback to lollipop without losing the ability to use air-watch?
Since the first release of oreo I started using the rom as a daily driver, later on paired with a good kernel it had some good perfomance
But after some days of using the rom i started to notice a huge battery drain caused by the Mobile network standby process?
My battery was old (OEM 2014 battery) so i decided to revert back to lineageOS just after a couple of days where I haven't had any issues with that mobile network standby
Now I'm really curious what is causing this issue,drain because I am using the phone on the same settings as on 7.1 nougat, I am living in a country where all networks run on 3G,H+,2G etc. so no 4G if this can be a cause
Changed the network modes many times and tested throughout the days but there was no sucess the drain was still persist, tried updating,downgrading bootloaders swithing modems but again no sucess
If there, in the world of android is any solution, here is the thread to discuss about this issue. :fingers-crossed:
I've wondered this too. I've been running los15 on my g900v , I rooted and boot the first ROM that would work without having or remembering todomuch, I ran the first custom kernal I could find via google, and ran whatever was noted as the latest Verizon modems. its like right off the bat, smooth , consistent battery life and nice. Then the next day I noticed things would crash, my Bt temperamental at best and restarted it just to get by. if I have sync on at home, WiFi off, it just chills , if I turn sync off and drive around town, my battery life gets eaten by the unknown. I pulled some logs to see whats up with my BT but haven't got around to it yet. But my battery too is old (I literally found my s5 in the trash) and I run weird processes and tweak settings all the time just to mess with it, so that could be it to. If I see anything weird I'll let you know.
I'm struggling with this issue for months, since the first port of an Oreo custom ROM (LOS and RR) for the Galaxy A3 Duos (my device) started being developed.
From the beginning I had this problem, and what, since then, puzzles me the most is the fact that only some of us, flashing the same ROM in the same device, experience the issue. Whenever I flash any of those ROMs, even before installing any user apps (or when running in safe mode), the drain is there, which leads me to think that the culprit must be some setting: not an app, because I have none installed; not the ROM itself, because not everybody has this problem.
Unfortunately there seems to be no developers looking into this bug.
For the sake of information, I've observed two things that should help to narrow down the issue; or maybe not.
First, all the devices affected, as far as I've searched, are double SIM.
Second, the Mobile Network Standby (MNS from now on) drain is narrowy connected with the Bluetooth drain (which "also" occurs in Oreo). I've experienced the following: If, after a full charge, I don't switch on Bluetooth at all, then what drains my battery (according to Advanced Battery Usage information) is MNS. However, if I switch bluetooth on -even if only for one minute- then what apparentlyh drains my battery is Bluetooth, at the same speed as MNS did before switching bluetooth on.
Funny enough, the battery use info reports zero minutes activity for both Bluetooth and MNS. But how can a process which runs zero minutes drain 50% of the battery?? I'm afraid that the battery use information isn't reliable. But then that's very bad news, since, in such case, it might well happen that the real juice sucker is neither MNS nor Bluetooth!! We might be dealing with a "ghost" here, since we can't even trust the battery use information provided by the OS.
If someone has something with which to contribute to this research, or any ideas, please comment.
I'm having the same trouble on android 9 betas, even better, my phone gets without signal during those times and there's nothing I could do but rebooting the phone.
How can we help solve this? it looks like it's annoying a lot of people now
