[Q] Problem after Rooting

Hi everyone
I have an international version of Note 3. The problem I'm facing is, after rooting my phone and installing Lidroid Custom ROM, the battery on my phone started draining badly. To get rid of the problem I reinstalled Stock ROM on it and also unrooted the phone. But the problem is still there.
Even without using the phone, the percentage drainage is about 1% every 10-15mns. Have removed all third party application from the phone, but to no avail.
Can something be done about this? I'm at wits end and need a solution badly. Please respond ASAP.
Thanks in advance.

Get wakelock detector from Google play see if it's a app draining the battery

Get into recovery mode and clean your cache, whatever bad bug went on with the custom ROM flash is still there. Once you clear it you should be OK.

Constantly Awake

Hi Guys,
I flashed the latest 5.0.1 Lollipop firmware (N910FXXU1BOC3) last week to my N910F Note 4.
Everything has been working okay. Until yesterday where the phone is constantly awake.
I have uninstalled all 3rd party apps and booted into safe mode yet it still shows as constantly awake in the power saving settings section.
I have tried using airplane mode, removing the battery for 10 minutes . Restarting multiple times to no avail......
Does Anyone have any suggestions?

Reflash the firmware again and do a full set up as if it was a brand new device.

I shall try that when I get home. I restored my phone from a backup after I originally flashed 5.0.1.
This time I shall keep it as a fresh firmware flash.

hi ,
your above post reminds me of my experience recently,with........BOC3
i upgraded from Android v 4.4.4 to BOB4 lollipop ( dirty flash ,no wipe, no factory reset ,
no problems at all .My device was running smooth ,no errors etc. battery ok .)
Flashed fom BOB4 to BOC3, i resetted my device etc .root recovery etc .
for a while everything was running fine,after a few days ,i started to have a bad wakelock .
Device was awake most of the time .
Lucky i was able to id/pinpoint culprit with" BetterBatteryStats " and Gsam battery monitor .
It was a system process something with....... Samsung security Filezip log..?
As i had an old app on hand "DisableService"( root ) and traced the process and unticked 3 relevant processes ( lucky guess ? ) and my wakelock is solved .Battery usage much better etc
BOC3 is just as good and stable as my previous v4.4.4 and BOB4...!!
So sometimes dirty flash works ok and sometimes flashing,then an factory reset..etc etc does not help.!
good luck

hi ,

Just make sure you download correct version !
Cwm recovery i used .... N910F vers 6.0.5.1 (1022)( see snip )
i have'nt correct link ..sorry
good luck

Have this issue myself with a N910F on 5.0.1 BOC3 (N910FXXU1BOC3 - CSC TDP). Without much Screen on time i get about 50% battery usage after 9h (usually when I get home from the office). It's not bad, but I would still wonder what the battery life would be like if I did not have the device constantly awake.
I would not want to root the device in order to avoid tripping the KNOX counter.
Is there any way to find and remove the wakelock culprit without rooting the device ?
I updated to 5.0.1 BOC3 from 4.4.4 ANK4 from Odin, wiping the device before and after.
Any ideas on how to proceed without tripping KNOX ?

I had the same problem and I fixed it when I disabled google backup from settings...
Maybe you could try this!

Thanks for the reply, but wanted to know what are you reffering to as google backup. Are you talking about the google sync for contacts, gmail, calendar, drive etc ?
Because on the device i have 2 google accounts that have gmail sync and another google account with gmail, contacts, drive and calendar.
I have disabled google+ photo backup.

There is a menu backup inside settings. Where it syncs wifi passwords etc with Google... I do not know how it is called in English because I use it with Greek names... But I think you can find it easily..

Seems that the wakelock issue is a thing of luck.
I have disabled some more sync options and additional stuff like Multi Window and On-Body Detection SmartLock but i had the same issue with the phone being constantly awake.
Every time i disabled a new feature, did a phone restart. What i noticed is that sometimes after the restart, the wakelock problem goes away, sometime the phone is still constantly awake. So from my point of view, without rooting the Note 4, i can say it's pure luck after a phone restart.
I'm loving that now i see 23% battery consumption after 12h with an estimated of 2 Days left - without power saver. It sure beats the 50% consumption after 8h with 8h left. But i still have to admin, with a constant wakelock on the device, the resolution of the screen, the battery life is .. WOW

Signing out of Google in the settings page then rebooting and signing back in stops the device being always awake. However, it seems Google Services is very buggy and for me the wake happens again after a few days randomly.

Happens with 5.1.1 too. Not rooted

CF-AUTOROOT (problem)

HI
recently flashed the new version of cf (with 5.1.1 support) now experiencing Some bugs like the multiwindow it goes on everytime no matter if i toggle it off or not , and phone overheating really bad and battery is going down really fast , tried fixing wakelocks and do some formatting and still the same (also securestorage is false) , any advice ?????
(problem coming from the root because i didnt installed any app with root access yet)
also wondering if these over-heating would do any harm to battery life??

Might be simple, but have you actually tried resetting the phone completely and re-rooting it?
Also, overheating can cause battery drain. The throttling of the CPU does require some power, so if you're phone is always running hot, yes, you will notice this.

A previous downgrade attempt has scarred me from trying to downgrade again

Back in December while i was still on 6.0.1 but on the latest monthly update at the time, I have known for awhile that there was a high android system battery drain after the february 2016 monthly update so I wanted to downgrade back to February. But when I was in the process of downgrading, I got an error on odin and it failed. After I restarted my phone I got a message saying "an error has occurred while updating the device software. Use emergency recovery function in the smart switch pc software" so at that time i was freaking out a bit and I went searching around and people said around may of 2016 samsung updated the bootloader so you couldn't downgrade to an earlier month that had the older bootloader.
I just want to know if samsung has updated their bootloader since 7.0 being on the latest bootloader. I'm currently on August security patch and want to go back to March.

I was using, if I'm not mistaken, the Android 7.0 July patch and I wanted to do an experiment. So, I downloaded version 6.0.1 and flashed using Odin.
Everything went through smoothly!
Just a curiosity, why do you want to go back to March? There are no benefits rolling back to an older patch, unless you want to test something.
Also, people say everywhere that their batteries are X with Y update and then, with Z, it got worse (or better). It actually depends on your usage, what apps you have installed, how you use your phone, etc etc etc.
Ah! My S7 Edge is the Exynos version.
Regards

I've had a serious kernel battery drain and i've tried whatever I could to fix it. It just started out of nowhere and I can't think of any apps that would cause it to continue and so my battery life has been horrible and it doesn't even go into doze half of the time and I also has forcedoze enabled.
If you were able to go back to 6.0.1 without having an error in odin, then what did i do wrong? I put all the right files in the right place.

What model is your phone? What country?
Battery drain, doze not starting... it's normally caused by apps.
Post a screenshot from Settings -> Device Maintenance -> Battery -> Battery Usage

Ohhh Canadaaa \o/
What I would suggest is to start from scratch, without restoring any backup.
If you want, you can download the current and older versions from here: https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935W8/
I'm also on August security patch and I consistently get 7h+ SOT but I disable preloaded apps, (especially Facebook), use the resolution in HD and a black theme to get the benefits of the AMOLED screen.
When using Odin, make sure you put everything on the right place and use CSC file instead of HOME_CSC. It will delete all your data!

I also have apps disabled or at least HAD them disabled..i've might have enabled them except the ones i know for sure i dont need like facebook, chrome and those microsoft apps...you get the idea. I use HD resolution and keep it on black or dark theme. I use substratum and have whatever apps are supported themed to black.
Also why not home_csc if im starting from scratch?

HOME_CSC will not wipe /data, CSC will. I may be crazy, but I erase things the maximum I can, so: I factory reset before updating to a new version, I use the CSC file to flash via Odin and I factory reset after I've updated. Then I log in to my Google account and start installing my apps from Play Store.
Of course I don't do it monthly (because security patches make no drastic changes). I only do it when there's a huge update (like Android 6.0 to 7.0) or when I feel the phone becomes sluggish (because I've installed and uninstalled lots of apps, for example).
When I had my Nexus 6, I also used fastboot commands and TWRP to garantee it's 100% clean (yep, you can now shout * crazy dudeeee *)

So I attempted it and it is a success!

G950F root battery drain

I'm posting this once again hoping one of you is experiencing the same problem.
The gist of the story is, when I root my phone, it drains battery quick leaving me with 2-2.5h SOT. When it's not rooted, it goes back up to 6h SOT.
This is not a rogue app problem, it's not a kernel problem, it's not a media scanner problem, it's a ROOT problem. And it stems from the days of Oreo, all the way to now where I'm on the latest OneUI build (February patch).
Somehow, when magisk or SuperSU is installed, it just drains battery quick. Does anyone have the same problem?
For clarification: tried safe mode, both rooted and u rooted with the same outcome: more drain on root than on non-root. Also tried COMPLETELY formatting the phone, and go from there with absolutely no third party apps installed; same outcome.
Thanks.
