smbchg_wake - Moto G4 Plus Questions & Answers

My device has some hardware issue, it thinks that its on charging even when its unplugged even the media does not get detected when I connect my phone to my laptop & lately I've been facing this issue, as per better battery stats (was able to run this app only after stopping charging by using an app called Disable USB Charging) this particular kernel wakelock 'smbchg_wake' is keeping my device active all the time even when its sleeping & it drains the battery quickly, I've tried almost all the roms but I am still facing the same issue, strangely even google has no info on this

Did the service center replaced the USB port? If so, let them check it again if you have warranty.

Since my phone was already out of service I got the port replaced by a local repair shop & the technician said that it could be a motherboard issue

My battery reduces even when charging

Hi all I think my charger input is damaged as it doesn't seem to charge any ideas or advice on what to do? I've bought a new charger but it hasn't helped

Same happened to me earlier these days. Have u tried charging via usb on a pc?

Make sure it isn't filled with pocket-fluff. That caused me some problems for a while.
Are you sure all the tasks are closed?
Look at the task manager, it happens to me when my web, facebook , facebook messanger a nd more couple of apps like games are opened at the same time.
close them all
Hi guy,
Does your battery become hot when charging ?
Perhaps you can wipe battery log it may help to start from 0 in battery stats.

Finally I find someone with the same issue. I still haven't figured out what causes it, but it only happens in some roms.
Sent from a dream.
Could be the cable as well.
Read quite often about it. Specially if you purchased a very cheap cable.
I'd take a look with battery monitor widget, how much mA is being put into your battery while charging.
Try another cable and see if it helps. If not, your battery may cause problems or your phone or the next cable isn't capable or whatever...
But it's pretty easy to find another cable for testing, right?
(don't know if you just bought a new charger or a cable as well)
Exactly! he is right. I had the same issue of charging and my pc also did not recognize my phone but I changed my cable I resolved all the issues regarding charging and pc recognition. Must check your cable and try to purchase an original one. I hope this will solve your problem.
Try charging it in the recovery.

[Q] Galaxy S4 won't charge

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!
Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?
Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob
Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.
Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...
Unfortunately that doesn't work for me, will send to service, let's see.
have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?
Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!
I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.
In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.
I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!
I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.
Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.
I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.

I've had this problem for a few weeks now and have yet to find a solution.
I'm quite astonished I haven't found a fix for this either. I have yet to open mine up ... I'm try to get the bootloader relocked, so I can warranty the dumb thing. But since it's not recognized by USB when powered on, I can't.
Have you tried putting pressure on the cable when it's plugged in? Also are you using the factory cable?
Sent from my Nexus 7(2012) that has zero issues.

Unfortunately it is a hardware failure. Most likely the USB port assembly. It is possible there is a loose ribbon cable connection.
Nexus 7 not charging
I have the same problem. My Nexus 7 will not charge when turned on. It will not now connect to my pc. I have checked the drivers and all are ok.
It happened a few days ago Its rooted. I can restore backups that are on my Nexus through rom manager, but still the same problem. I thought of doing a factory reset, but if it will still not connect to my pc. I will loose the data. If it is a hardware usb port failure, what is the next stop
I know this is going to sound strange but open up the back of the Nexus and you will find your battery... And you will notice that it's loose you have to plug or wedge it back on to the battery clip it comes loose overtime use a credit card or similar to open the case :thumbup: success

Similar thing happened to me... No amount of pressure or angling of the charging port would work. Batteries ran dead as a result. Sent it to the service center and they would assess it for 2-3 days and try to repair since it is under warranty. I'm gonna get an official dock to try and save the charging port from the stress of always being in use although I know that's not the only factor at play.

That's sounds a good idea with the official dock for charging, but you should not have to do that.
To much usage of the micro usb port is going to give problems. I'm always connected to my pc, downloading roms ect. but as I said before, my N7 charges perfectly when not turned on.

As I can't connect my N7 to my pc. Is there anyway to revert to stock. Need to return for repair. USB port not working as it should.

I think the only answer is a faulty USB connection.
I tried to change mine and finished up snapping the connectors. :crying:
Now have one useless N7
Long story short: plugged the n7 into the car's OEM stereo USB port on a long trip and it registered as a device with the stereo and let me play some music off of it, when I woke up a couple hours later it wouldn't charge.
After a short bit of troubleshooting, I found that OTG devices were still working but it would only charge if I shut it right down - if I start it charging while it's turned off and leave the charger attached while powering it up it's not detected by the software so it never says it's charging, but does still charge - though if at any point I pull the charger from either the n7 or it's supply I have to shut it right down again to get it to charge. Unfortunately, the same can't be said of a PC USB device connection (aside from the charging part of course.)
After a couple weeks using it like this, I got my hands on a multimeter (my stuff is all packed in storage indefinitely or I'd have been replying to this topic sooner) and confirmed that I never register anything beyond a few millivolts on the detect/sense pin (which I find very odd as it's supposed to have a pull-up) with nothing attached to the usb port, and that aside from a short time in fasboot that unless the n7 is powered right off it's trying to supply 5V to the USB connector. I attempted to use the faux123 kernel that has options to disable this power to allow host+charging (and my hope was to slow the battery rundown to make it more usable even if I have to shut it off to charge it), but the n7 appears to ignore this and still powers the USB connector.
In this case it most definitely is NOT the IO/USB/headphone assembly inside the unit. At the moment I'm operating on the theory that Asus skimped on protection circuitry in the charge circuit as in my mind this type of damage should never occur when it's properly designed, and I'm presuming the motherboard dead with regards to being a USB device - too bad my warranty is likely up, though I can't check that as it was a gift and all the paperwork is buried in storage. Thankfully it's still capable of fast charging when off, though this doesn't leave me very happy as this also effectively takes away most recovery options if fastboot is the only thing left working.
If I manage to source a replacement mobo I will work on doing a post-mortem and seeing if it's down to a faulty component (I've seen this sort of behaviour before, a pulled up line not getting pulled up, when a filtering capacitor decides to go flakey.) More likely though I'll either sell it, give it away or put it on the junk pile with the rest of the Asus products I've had to retire in the last month due to their questionable customer support (the other products were due to Asus deciding they were "legacy products" and not updating drivers for windows 8/8.1 despite only being 5 years old.)

Very Interesting
I am sure you are right, but I'm not qualified to agree or disagree.
I have had quite a few Asus products in the past and never had any problems.
My Nexus 7 (2012) was also charging properly. I only have the issue that it only charge when turned off AFTER I charged it:
(1) using car charger; and
(2) charge it using official charger but inside a train using train's power plug
So it seems that these devices really need a normal wall-charging paired with official charger.. otherwise, something bad might happen..
Has anyone tried to use Wireless Charger? does it work?

[Q] Weird galaxy note 3 problem

Good morning folks, I have a strange problem with my galaxy note 3.
Since a few days, he would not charge.
When I connect it to the charger it does shows the lightning bolt on the screen, also in the menu it says Charging.
But the % are decreasing instead of increasing
When i connect it to my computer it's fully functional reading/writing also reconized by KIES.
1. First I thought the battery was broken, but this was not the case.
I put the battery in another note 3 and he just did it to charge.
2. The charger itself is not broken, the cable either. This just works with the other note.
3. Charging synch port replaced the phone, problem is not going away.
4. I have set up a custom ROM, it does not work.
5. Returning to the original stockrom
6. Carried out by phone shop Moisture Treatment
But the problem is not solved.
Should I start thinking about a motherboard problem here?
Or maybe you know something I can try.
Thank you very much in advance.
Greetings Johan

Msm_otg wakelock

Hello everyone.
So there's been a quite few roms around the last weeks enough updates and all that. I noticed that on all roms(literally all of them cm11,cm12.1,RR,MOTION ROM) I get a wakelock named msm_otg after I fully charge my phone and disconnect my charger. This wakelock disables deep sleep and doesn't let the phone sleep on screen off. Is there anyone that can confirm this and maybe we can try a fix? Only fix at the moment is to reboot the device but I don't see a reason why I should always reboot my phone after I charge it. (my device is gti9301i)

@zigbye82 nope I use stock charger :-/
The only solution, as for now, is to restart your phone after being charged.
I would suggest that you try charging using a different cable or charger and see if problem is still there. For me this wakelock is high when i charge with usb but goes away when i disconnect.

What cable/charger combination helped you? :-/
I dont have this problem. What i'm saying is when i charge my phone on pc the Msm_otg wakelock is high but it goes away when i disconnect from pc. When i charge with my charger i dont get this problem. Maybe you have a defective usb cable or charge.

I dont think you are understanding me.

Confirm! This wakelock is related to change state in the internal memory and usb state. Change the cable and check your kernel. In Cm11 and Cm12.1 there is no problem. Ive got this wakelock when using my phone like external flash drive. Don't worry
If you keep getting issues, just reboot right after unpluged the device.
Their whose attempt to resolve this in last public Samsung source. Did it work I don't know?
Recommendation goes for kernel makers along with rom maker's to disable the future on kernel side (as it's been done for CM13).
For those who would say that they need USB OTG I would say it never whose handy anyway as thanks to not power compliant USB controller QC traditionally used it requires external power source & cable with a plug for it.
Using any cable or charger won't change this! All do I admit that charging module placed in cellular modem section can be itchy (from jamming l at full charged to celullular network collapse until whole module is automatically restarted & when that fails to happen even causing kernel panic [making phone to restart]) so use quality cable's/charger.
