I have searched all over the web and haven't found this pop up that much, I can't find anything in particular that could be causing this wakelock. Once the wakelock starts, it keeps the phone awake 100% of the time. Running CM11 M2 snapshot with various kernels (stock CM, Hells core, AK at the moment) and it appears with all 3 kernels.
I'm running BetterBatteryStats (doesn't show anything aside from pointing out it's 'Slimport Wakelock' and Wakelock detector doesn't even register 'Slimport wakelock' and doesn't seem to show anything rogue....
Any help?
same here
I have the same Issue. though my OS is vanilla 4.4.2
Iv'e recently had to change my usb socket because phone was not charging. I think the issue started then. did you mannage to solve yours/did you also change your usb/charge socket?
A
I have the solution guys... Though its hard to explain, its not very hard to accomplish.
I took my n4 for another try in a different lab. The technician from the start suspected it's not something in the charging port itself, so he asked me to leave the phone for him for a few days.
After 4 days of trying and learning, he managed to find that the problem is in the socket on the board itself is causing the problems, along with the charging port, in my case.
He replaced the port on the board itself and the problem is solved.
Eventually, I paid 40€ for this problem, not very high, beats the other option (buying a new phone)
Try it guys.
what do you mean the socket? is this what he replaced?

i had this problem since i got the universal which is about 6
months ago, the problem is that when the battery is 100% the green led is stuck even when i remove the charger, and in the power settings "charging" wont go away, and the battey is dead in less than 3 hours on standby, i tried another ROM and another battery but its no use, is there any solution, i really need help.
thanx in advance
Have same problem... any help
Probably problem with M/B, small chip that control charging. But check the WIKI first I think I saw something about this problem.
pl chk all radios are off. I had same problem last year but in my case I was using whatever source of power such as car charger, Inverter, ect. I'm using only my laptop now. Charging Voltage can damage your batt real fast.
The charge control chip is in the battery pack, not on the mainboard. While it is possible that the OS is reporting false based on the data it receives from the chip, it is unlikely since he says he tried other ROMs as well, which would have eliminated the problem.
I would have also thought of a dying battery, but he has tried another battery without success.
My best guess is that the power routing chip is either damaged or miscalibrated, and evaluates the received data wrong, leading to excessive power drain, even in standby mode, for example by keeping WiFi powered, and not instructing the CPU to throttle down.
The "stuck" LED, however, indicates a different problem, as LED control is a separate aspect of the motherboard firmware.
I would recommend backing up everything, and using mtty to format the DOC, which should erase everything. After that, install you ROM of choice, and if the damage is not hardware-based, it should be fixed. If it is hardware based, then I'm afraid only a qualified service can help, most probably the device vendor, if the warranty is still valid.
Hi all, picked up a GS2 the other day which had the USB charging issue. i.e. Plug charger in and it either wont show up or gives false data and unplug it still shows charging. Also, the battery temp sign showing and battery pull leaves a fully charged battery dead!
Looked around on here and on the net for various causes and possible fixes. These ranged from changing ROM, replacing the USB charging port, calibrating the battery, any number of different things etc etc.
So in theory, it is either a software issue and/or a hardware issue! But to me that made NO SENSE. It couldn't be both, well maybe for a small % of people it could be but for the majority, it had to be something else.
Well, as it would seem from my findings, in my case, it was something else. It would appear that the MODEM/RIL combo is causing the issue.
I tested this on my non-functioning device by flashing a new MODEM/RIL combination and then re-flashing the old one just to check. The old one has the issue, the new combo it is gone!
So IF you have this issue, try flashing a new MODEM/RIL combo and see IF it fixes the problem BEFORE spending any money on repairs.
As IF by some wacky coincidence forum member hawkerpaul has created a thread just today with CWM flashable MODEM/RIL's combo's, find them herehere
Hope this solves the issue for you as well

I just want you guys to help me diagnose the problem.
I was charging my phone yesterday with a cheap car charger.
My phone now produces lots of heat, eats lots of current (discharges quickly) and USB is not working (only charging).
I tried flashing different radios, kernels, stock rom and factory reset - didn't help.
Plugging a phone into Ubuntu PC doesn't add any logs about new USB device in dmesg, even in fastboot mode.
My questions:
1. What can cause SoC to produce heat and to discarge battery very quickly?
2. Is it a failure of a USB board or of the SoC itself?
I have two options on eBay: logic board and usb board.
It would be great to buy a 16GB motherboard instead of my current 8GB, but I want to address the problem with less money spent on it.
I don't know which one to buy.
same problem
Unforunetly I don't have a solution for you, I have been experiencing the same problem since last week. My phone no longer charges in AC mode, I can't connect it to any PC (fastboot doesn't work), and the battery is draining fast (from Phone Idle process). It is warm when the screen is off. I am on Android 4.3, it was working fine up until last week.
I'm about ready to RMA it, however it's interesting that I am not the only one experiencing this problem lately.

What did you do with your phone before it started behaving this way?

I'm not sure what caused it, I have a feeling it's similar to what happened to yours. I use a blackberry car charger in my car, and at work I use a non LG AC charger. So I'm thinking it was the car charger, but the weird thing is it has been working fine with both chargers for 6+ months.

Another thing is that I was installing a faux kernel 3 days ago, but it didn't cause these symptoms instantaneously (instead, it made my nexus super power-efficient), so I don't think that was the cause, too.
P.S. Google's RMA policy doesn't allow to return phones after 15 days, so I think the best choice would be to buy a broken phone and interchange the parts.

I haven't used any custom kernels or ROMs. I am rooted with custom recovery though.
There is a 1 year warranty on the phone, and I am within that 1 year so I hope to be able to get a replacement. This appears to be a hardware problem.
edit: Have you tried taking the battery out? In previous phones when stuff like this would happen I was able to pull the battery out. I tried to open my phone but it's a pain to pry open without breaking something.

No, but I will do this tomorrow. I don't know if this helps.
P.S. Sometimes I get this in dmesg:
Code:
[738145.499853] hub 2-1:1.0: unable to enumerate USB device on port 8
...which is not good either.
Well, I tried removing the battery - that didn't help.
What actually helped, is the following:
1. Bought cheap broken nexus.
2. Exchanged motherboard and usb board with my existing device.
3. Sold broken nexus for cheaper price.
4. ...Profit!
Now my nexus works again, and more than that, it has 16gb instead of 8gb. It wasn't hard.
I'm happy now.
Note 4 won't charge over USB anymore. Used to charge intermittently after being plugged in for some time but now won't charge at all. Tried all manner of cords and adapters. When powered off, the phone strangely keeps vibrating continuously. Any help with this greatly appreciated!

Don't think anyone will be able to help here with that sort of issue. Either flash a ROM after a complete wipe to see whether it goes away, highly unlikely, so then the most obvious solution, service centre.
Had a similar issue, changed the USB charge port and still nothing, I'm going to try the flash next
Is your battery OK ie any signs of swelling, leakage or damage?
If your able to try a known working Note 4 battery in your device it makes sense.
Also may be worth cleaning out the USB port with compressed air as at time dust build up over time in the port may also cause your device not to charge.
did everything mentioned, with no result, tried a new ROM and nothing, ive been speaking to persons and theyre saying it might be a board issue...

It totally sounds hardware related. Did you try a new battery, too?
Have a Sm-T530NU that has misbehaved for a long while, originally the OEM battery was thought bad. Yet after it was changed to a new off-brand battery and working on and off for a year and some, the tablet has started misbehaving again, mostly not charging and turning off alone. And recently has started showing the temperature warning icon while charging while off.
So, I've opened it again and digged down, and discovered the battery connector on the PCB wasn't well soldered, the contacts danced in the pad, so I retouched the soldering with flux and a little new solder and it seems ok (I can recheck again later if needed be), so I tested the original battery with multimeter and seemed acceptable, so I installed the original battery back. Charged it for a while, and, again, warning icon for temperature while off, and it switches back and forth between charging and warning... I turned it on, and it works, but throws an error once in a while about being too hot and closes all apps... this, I think should be something related to cpu heat and not battery one... (also wasnt charging during this). So, I read online that some of these tablets with a modem have a service menu (*#0*#) but of course this one has no dialer, so I've tried several programs to try and get into the service menu, my idea is to see if it's possible to recalibrate temperature sensors, for battery and for cpu, but I've not been able to open the service menu by any means (the last mean I have is trying an intent initiated by am but the tablet is not rooted and there's permission issue for asking an intent of uid 2 from uid 0....).
My questions are:
1) Is it possible to get to the service menu of this model somehow? with or without rooting? Is it possible to recalibrate sensors from it?
2) Should I recheck the battery connector? would a battery "overheat" (caused by a bad connector connection to the sensor cable, or a miscalibration) cause app shutdown during run? or is it related to cpu/gpu overheat? I see some phoen models (S2) can cause this message from torubles with the usb connector/pcb, this doesn't sound too logical on my case, but, is it a possible source of problems for this tablet too?
3) If it IS a cpu overheat (though tablet feels cool to the touch) is there anything can be done to help with this issue? micro disipator maybe?
Thanks for any advice. I'm willing to try odd or hard stuff to fix this.
