Android OS battery drain still present on 2.3.4 XXJVR

OK, this is unbelievable.
The battery drain on XXJVO was driving me crazy. Reading the forums I noticed some people said the Android OS issue was fixed on 2.3.4. Yesterday, I flashed XXJVR with re-partition and bootloaders via Odin, using the OXAJVQ CSC. I also installed the Voodoo lagfix for XXJVR.
I did a factory reset before and after the flash. Did a battery pull, all the steps that we're used to.
For my surprise, a few minutes ago, the phone discharged in 8 hours to 47%. Guess what? Its the Android OS again. Take a look at the attached screenshots.
Did I do something wrong? Is this normal on 2.3.4?
EDIT: Following $omator and madrooster's advice, I decided to flash everything again from scratch and install all the apps directly from the Android Market. Apparently, the issue was being triggered by a restored appdata backup via TitaniumBackup. I've been using the phone for about a week now, with no issues at all.

im running custom rom gingerreal 7.1.4 JVQ with galaxianEE kernel and lagfix enabled. my modem is ZSJPG and csc XAJVQ.
no issues like u have.
but i have to say, that the battery drain is heavier than on froyo.

Man, that's pretty serious drain. I'm running Ramad's stock deodexed JVR since it was postes with semaphore kernel and my usage is never more than 15%. Why don't you post a pic of the bigger graph?

only way to avoid battery drain is that you remove the battery from phone

have no idea haw did you managed to break jvr but you did it =)
i guess youve runed some app that was not letting phone to sleep
or the system got some broken ones tat caused this (yes wrongly flashed system maybe hehe)
btw notice the blue line under your graph - it should look more like on attached screen

Im also running gingerreal 7.1.4 JVQ with semaphore 1.32 and after 2 weeks of use no battery drain.
Android OS is always below 10% (mostly on 4-5%)

The Android OS bug was fixed from stock JVQ onwards. The reason you guys experience that is because you are using custom kernels built from old source codes released by Samsung or heavily modified by the developer. Go complain to your respective custom kernel thread.

Thanks jb. That could be the reason. I am using Voodoo kernel, maybe that's what causing the drain. Has anyone else on Voodoo experienced the same problem?

jb, I remember that I played Captain America in the morning, but the phone froze and I had to battery pull it. After the restart, I didn't touch it again for like 6 hours. In the night, the phone rang and when I tried to pick up the call, the screen wouldn't turn on, so I had to battery pull it again.
After I turned it back on, I checked the battery stats and noticed the Android OS was running crazy, as you can see in the screenshots.
Captain America afaik is not sensor based, and I battery pulled the phone after I played, cuz it froze. I'd love to blame the game, but I cannot.
Edit: But... looking at the stats, the orientationd process is right next to the Android OS. Could this happen if the phone wasn't resting on a flat surface? :S

Yup the orientationd process was burning you battery juice, the reason why you got Android OS bug. I guess you should try to change your custom kernel or if you really like your current phone setup, you should install Watchdog lite or any similar app to monitor system processes, such as Android OS, for unusually high cpu usage and just reboot your phone when it does occur

i wonder what else is broken in this guys phone that wathcdog and reserting will not fix =)

$omator help me out here. What kernel would you recommend for JVR that keeps everything as stock as possible but includes lagfix? I use Voodoo since it is pretty light, but it doesn't seem to behave so well after all.

stock + cfroot is always a win

Android os drain goes away for my 2.3.3 kg3 stock setup after wiping cache partition and dalvik cache. Ran for weeks and never came back.

This battery drain problem is caused by the kernel you have. It is caused by a bug in a specific device driver.
The phone tries to go into power save mode but something prevents it. When the phone fails to reach a low power mode, you see the battery drain. In summary, if you run a custom, non stock Rom you might not have the battery drain fix. Try to make sure that any custom kernel you use has the same kernel version as stock.

Wow that is pretty big drain.. On my xxjvr (2.3.4 ) it only uses 9 to 10% don't know what's wrong though

Not for me...
1. Clean the phone.
Flashed JVR (from samfirmware). Flashed CF-Root-XX_OXA_JVR-v4.1-CWM3RFS. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings (NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 22.00 hour battery was at 98%.
Next day in the morning at 10.30 hour, the phone beeps that the battery is at 15%... Looking in the Battery use, discover that in about 12 hours, the Android OS (90%) is draining the battery. OMG...
2. Fully charge the phone, clean the phone.
Flashed JVR (from samfirmware). Flashed speedmod-kernel-k15i-t10. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings(NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 22.00 hour battery was at 96%. Next day in the morning at 09.30 hour, check the phone.
Surprise! At about 12 hours, the battery "lose" only 4%. And NO Android OS in the battery use.
3. Next day, clean the phone. Fully charge the phone.
Flashed JVR (from samfirmware). Flashed TalonDEV-0.4.4.22-1200-I9000-BIGMEM-CWM3. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX. All closed by me in settings(NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 23.00 hour battery was at 98%. Next day in the morning at 08.00 hour, check the phone.
Surprise! At about 10 hours, the battery "lose" only 5%. And NO Android OS in the battery use.
4. Next day, clean the phone. Fully charged battery.
Download again the CF-Root-XX_OXA_JVR-v4.1-CWM3RFS.
Flashed JVR (from samfirmware). Flashed again CF-Root-XX_OXA_JVR-v4.1-CWM3RFS. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings (NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 21.00 hour battery was at 90%. Next day in the morning at 07.00 hour, looking in the Battery use, discover that in about 8 hours, the Android OS (90%) is draining the battery and the battery is at 25%...
I'm not a specialist in Android, but with this experiment, understand that in my case, the "drayner" of the battery was decided by the kernel, and I decided to flash the JVR stock+ with speedmod-kernel-k15i-t10.
I don't say that the CFroot is bad or that another kernel is good, but for me CFroot don't works good.

How do i flash back to a previous modem?

hey guys, so i have a retgb stock rom for lollipop, how would i go about just flashing the modem from that rom. I want to do this to test a theory i have about the battery drain on marshmallow, to see if its caused by the new modem, any help would be appreciated...

certainly not caused by the modem. Did you clean flash? What did you do to upgrade? etc? have you disabled wifi/bluetooth scanning in the extended location settings, deleted play services data yet?

updated from a stock moto x play single sim, retgb to marshmellow via normal ota, had no root or bootloader unlocked. After the ota i installed twrp and rooted, wiped cache and data, did a factory reset. Then did everything you said above. Then tried with squid kernel, still have massive battery drain about 1 hour sot and barely lasts me 1 day. So yea... i thought it was worth a shot just trying my idea about the modem...

Mobile standby and phone idle, i have xposed and greenify installed, no speacial apps installed if you dont include kernel adiutor. Im gonna try going back to 5.1.1 stock and try a 6.0 stock rom via twrp, il post the results later.

Frequency stats probably show deep sleep as unused state?

no, deep sleep is being used like 92% of the time

So basically everything is working fine. In some other thread I read xposed seriously cripples battery life. I'm not using it so I can't tell

well im currently going back to stock 5.1.1 for now, im gonna try my therory, then i try with and without xposed, see if it makes a difference

@Benjamin_L well i can safely say that xposed makes no differece that i can see to the battery life so far. After flashing the old stock (5.0, including the modem, through fastboot) then going back to 6.0 by flashing the stock rom by GtrCraft via twrp my battery life seems to have improved quite a bit. So maybe it is the modem after all? Also why did you say it cant be the modem in the first post? just curious...

I ran both modems on 5.1.1 and 6.0 on several roms and stock firmwares and there was no difference, except for rom related things. And I never heard modem influences battery life dramtically if at all. On my old n4 i flashed several basebands and never noticed any difference in battery consumption at all.

Battery Life under Android Marshmallow 6.0.1

How is your battery life under Android Marshmallow 6.0.1?
I updated the new N920CXXU2BPB6 (CAM) and after 2hours and 20mins its down to 77% from full charged (( and also the fast charging is slowly

You had a root b4 M

I'm none root

I think there is issue with the drain, but it's not sammy fault. if you google Android 6.0.1 problem you'll see many nexus users pointing out that their is a battery drain issue, hope sammy can fix it or it won't affect us as much, Android M suppose to kill those issues it seems like Lollipop 5.0 again.

Here are my battery usage. I think thats not good. Lollipop was better.
Sync, Bluetooth, wlan is off. Screen is autobrightness at 100%
Anybdoy a idea?

One day is not enought to say anything about battery life ... maybe after couple of days .

Android os consumes my battery 8%... is this a fee for root my device by samsung??? What the f.... is that?? I cant use my phone without root or custom kernel??? F.... off samsung!!

Thought I'm alone, anyways, the screen on-time is not bad and can go to 6 hours (if used at once), however when the phone is off, the battery drain is huge and doze mode doesn't seem to be working either..
from 2 to 6 am, the phone was on a table and I was asleep and the drains looks to be huge

No problem with drain for me

Guys i think the issue is with root. IF you rooted your phone before, installed customer rom, installed kernel or installed recovery this issue will happen .
Someone on the forum point it to knox fused burn and it can no longer go back to normal.

Rightly said.
If you have tripped Knox while rooting previously, never ever installing a STOCK ROM (May it be lollipop or MM) will fix the battery drain issue since there is some read cycle which the kernel does continuously if the Knox is tripped which can only be overridden with a Custom Kernel.
So, either wait till we get a custom Kernel on MM and root (Ofcourse) or enjoy the new Look n Feel at the cost of battery drain
Btw, I am un-rooted on Stock N9208 (Waiting for MM in my region)

You will never get stock everything deepsleep. So all future updates are null and void for everyone. Unless you get a modified stock kernel to fix the deepsleep. Or a custom kernel. Unrooting doesn't help as Knox ix 0x1

S7 Edge G935F Nougat serious problem. Please Help !

Hello Community,
im from Germany, so don't judge me if my english skills are not that good.
So here is my problem.
I couldnt wait for the new nougat update. I decided to flash the beta 3 i guess with odin. Everything has gone right, the battery life was perfect, the performance great, everything was really smooth until i tried to get twrp on it. Ive got an endless bootloop. I flashed nougat again and everything was great. However now my battery life is the worst. I charged it to 70% it dropped down to 5% in like 3,5 hours ? I have nothing installed except whatsapp and the XDA App. I deactivated facebook, galaxy store and every bloatware.
It took about 2 hours to get from 5% to 32% with the fast charge enabled. When disabled it took longer.
i have wiped the cache section and nothing helped. I wiped all data and installed my backup from smart switch ive done befor i wiped everything.
Please i need help, im afraid that i broke my battery.

I dont think you have made it kapput. Flash the stock firmware back and see if the problem is solved. Beta versions of software usually come with bugs, sometimes many , some times a few. I remember when lollipop just came out, i installed on my droid rarz and i hard a simarly problem to you. I just flashed my stock ROM back and every returned to normal

The Problem is, i did not have the problem when i flashed it first. But the second or third time ruined something i guess.
I dont want the stock marshmallow rom back to be honest.

Just try and see if the problem still persist. I think that's the only way you can find out if its the rom or u breaked your phone

i say it again, i did go back on the stock. And yes, the battery life was kinda better. And then i flashed nougat back. The problem is, why is the android system draining so much with 30% for the total battery consumption.
