[Q] Wifi-Wakelock - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello!
I've made everything possible, to reset my phone, i flashed a newly fresh Stock ROM with ODIN and deleted everything on my intern SD-Card. So actually it should be clean and fresh.
But my Wifi-Module still doesn't let my phone sleep. It wakelocks the whole phone to 95%!
I use Wakelock Detector, to see what's happend and I can see that wlan_rx_wake and wlan_wd_wake are the problem. When I shut wifi off, everything works fine and my battery doesn't drain so fast.
Can I replace the Wi-Fi-Module? Or do you know any solution?
Thanks,
Jan

Meizu MX2 kernel wakelock

Hi,
pain-in-ass is "s5p-ehci" - it's active during whole night and my phone does not sleep at all!
Does anyone have idea how to get rid of this? How something related to USB can be involved in wakelock of unplugged phone??
There is no alternative kernel, otherwise I'd flash it already...
And neither I found any relevant info as to this wakelock issue.
p.s. Firmware is 3.4.5 HK. Please, do not suggest to re-flash again, it's silly, I wanna find the root of the problem.
UPD: I re-flashed with wipe. I uninstalled all user apps, turned off sync and location. I freezed google play and google framework. After several hours of doing fine the phone is getting possessed by s5p-ehci and does not sleep anymore...
DAMN!

Enormous battery drain caused by *alarm*

Hi guys!
I'm on newest (5.5.1) version of resurrection rom for d802. Everything works fine except battery lifetime which in best case scenario is bad. Problem is probably caused by *alarm* wakelock which seems to prevent phone from entering deep sleep and it keeps phone around 1.0-1.2 GHz on offscreen. Morever it affects multiple apps, even those I haven't ran even once. I tried wiping all data and system, clean flashing multiple ROMs and even going going back to stock JB and then again following flashing instructions for resurrection ROM, same happens on BlissPop ROM and slimsaber.
Any help would be greatly appreciated, it really does make phone almost unusable.

Android System Battery Draining

Hi all
I'm kinda frustrated and this is my story.
I have Edge + for less than an month (this is my firs Samsung device). I feel pretty familiar with the rooting and other installation, so after I got this device I installed PhilZ Recovery and the Arter kernel.
The device was kinda laggy and after I've tried to restart the device it stock on FRP lock and I flashed the original firmware and decided to let it chance. After that no matter what I did including reflashing
the original firmware, Android System keeps draining the battery, in one night it lose 30% with doing nothing (I guess it is some deep sleep bug). It's like CPU works half of the time while the device is turned on
(with or without Screen is ON).
My question is why actually this happen? Is it common issue with the original firmware? What can I do?
All advises will be welcomed.
Thanks!

I would suggest finding the stock firmware and kernel and re flashing both clean. I have the Edge+ international version and I also rooted and flashed the Arter kernel... But i do not have deep sleep issues. I will loose probably 2-3% battery over night with sync and Wi-Fi off.

That exactly what I did I flashed (even a few times) the original kernel and ROM via Odin but the issue is still there.
2-3% per night it's nothing comparing to my 30% So I guess you don't have any deep sleep issue

Hey. Yeah G3 is the best in deep sleep case. no drainage for a day for 6 days just %1,, but too much drainage while using tho
I'm not sure if my problem is the same as yours. But my phone was facing the same battery issue on stock firmware. I turn off everything, even with flight mode on, the battery drain was like 30-40% overnight.
After I installed gsam battery monitor, I found out that the android system was the main culprit. The android system drain amount was like 7-10 times to kernel (android os), and the apps also showed that my phone was kept awake all the time. No matter what firmware I used, the problem still persists. Fortunately, the problem was then solved when I installed arter97 kernel, or any kernels other than the stock one.

Yea, this is the exact my problem. Eventually I flashed Arter97 kernel and seems like the issue actually disappeared.
Thanks!

Hard reboot when device goes to deep sleep / doze

Hi all,
I'm running the official 6.0 ROM from this thread and the latest baseband/modem/bootloader from this thread. The ROM is working smoothly apart from 1 crucial issue: whenever the devices goes into deep sleep it reboots itself.
- This doesn't happen when the screen is on or the device is otherwise active (e.g. it didn't reboot when I was moving data off of it to a PC)
- This doesn't happen when the SIM is locked / when the device does a reboot and I don't touch it (e.g. it reboots when I go to sleep and it will be up and running the next morning - battery log shows it has been on without interruptions throughout the night)
Obviously a quite frustrating issue and I don't know where the problem lies. Any help or ideas much appreciated.
1. Backup what you want to save.
2. Wipe /system and /data
3. Start from scratch
Use the phone without installing any apps. If it works then the rom is fine. Then try installingen the apps you want to use and keep testing.
