I keep finding this going on. A few times now I've noticed my phone discharging fast. I check with Better Battery Stats and find that that I've had "USB CB Wake Lock" going on for hours. I'm not sure but I think it starts while being charged during the night. A reboot shuts it off.
I'm not sure how to catch a log cat of this. Could I start the log when I notice it or would it need to be on when it starts? Or maybe someone out there already knows what's going on with it?
I googled it and found someone who said they needed to replace their USB port. I kinda wonder if I might have an issue with mine. I use it on my car dock almost every time I drive. The cable on my dock is fairly hard to plug in. It doesn't just line up correctly and I have to jiggle it around a little to plug it in. The reason I got this dock is because I can mount my big phone with an Otterbox case on it.
The thing is the wake lock seems to start up while it's on the stock phone charger rather than the car dock.
Maybe it's software related. I use Tweaked VZW Remix I had the PB&J Kernel til yesterday afternoon when I switched back to stock. But this morning I found the wake lock with the stock kernel.
I'd just start up a logcat but if I have to leave it on overnight it'll wind up being huge. I don't know what to do here. Anybody got any ideas?

Saw your post on tweaked thread... Been a while, but I think couple of things to try are... turn phone on before unplugging, try cleaning usb port with toothbrush and/or compressed air (pull battery before doing this). Last resort, replace usb... think it is only around $20? There are videos on how to do this. Not that hard if you're technically inclined at all.
Ok I tried cleaning out the USB port. We'll see. I do have a problem with metal shavings at work and once in a while I find that I've left the USB flap on my Otterbox open. I guess I need to be more careful. I hope that takes care of it. It seems to me like if it was a hardware thing rebooting wouldn't necessarily fix it. But I guess it could.

Well so far so good. Thanks man.
Here's what I have this morning. I found some info that said this happens while charging. That's about how long it was on the charger last night. I guess as long as it's charging while this wakelock is activated it's ok. The reason I've been concerned is I found this reading 1 day & 19 hours once. Maybe it's not a big deal. I'm gonna keep an eye on it. My phone doesn't seem to be discharging fast today.
Sent from my SCH-I605 with Tweaked VZW Remix using Tapatalk 4
Ok it's pretty obvious this wakelock is what it does while charging. This morning it added 7 hours to the 7 from yesterday and it shows 14 now. I guess the time it showed all those hours it hadn't been rebooted for a week. There must be another reason for the occasional fast discharge. I guess I need to keep watching this. It's probably about bad signals. It's a good thing we have Better Battery Stats. It's definitely worthwhile.

Several days ago my phone started behaving strangely. Whenever the phone is NOT plugged in, the battery icon flashes continuously. If i plug it in, it stops flashing and behaves normally to show the phone is charging. Also, when the phone is NOT plugged in, the lock screen says it is charging. My battery life is dismal.
When i unplug the phone the battery indicator remains at 100% for a long time, but then drops quickly.Since this started i have to charge the phone twice a day with only moderate usage.
I am now on Shostock2 4.1.5 and Siyah 4.1.1. I tried factory reset, clearing cache and clearing dalvik. I also tried installing a different kernel (dream kernel) and a different ROM (aberration), wiping data, cache and dalvik each time.
I searched the forums, and the only threads i found seem to point to a bad usb port. One thread suggested cleaning the port, which i did using alcohol and compressed air. It helped for about half an hour, and then the problem returned.
Everything seems to point to a usb port that for some reason makes the phone think it is plugged in all the time...perhaps it is somehow shorted? So, it sounds as if my next step is to replace the usb port.
Still, I wanted to ask if anyone had any other possible solutions i could try before sending the phone for warranty repair and get the port replaced (or replace it myself).
Any ideas?
You are being kind of vague here. For instance. U say u have to charge it twice a day with .moderate usage. What if your moderate usage is 2.5 hours screen on time or something. To me, that means of course u will need to charge again if u want to make it he whole day. A bit moar info? Some cowbell?

Moderate usage means (for me anyway having the phone on, wifi on, gps off, no gaming. I only turn the screen on to check email for a couple of minutes here and there, and to answer the occasional call. Before the problem started my phone used to go all day without recharging. Now, even if i let the phone sit, unused, untouched, screen off (like overnight) battery level will drop over 10%per hour. I tried using better battery stats but none of the triggers have been triggered: if i try "since unplugged" or "since charged" or "since screen off" they all show zero seconds...I'm guessing that being "plugged in" continuously is messing with the triggers.
Still, the battery drain is not really the problem. The problem is that the phone seems to think it is plugged in continuously, even when it is not. It sounds like a bad usb port, or a port about to fail completely, but before i try to replace it i wanted to know if anyone had any other possible ideas.
People usually scrub the inside of the port with an alcohol swab if I'm not mistaken. Thought I've seen that posted, never had this problems myself.

My USB port needs to be replaced due to wear ( loose fit of cable). The ones for I777 I have found are $7.00 but are port alone, ones that are for I9100 are $15.00 but are attached to the ribbon cable. I plan to take phone apart to try to determine if the I9100 part will work. The price to have it repaired by MobileTechVideos is $40.00 plus shipping.

Definitely sounds like symptoms of a bad USB port to me. One thing you might do if you want additional confirmation, is to flash back to stock firmware (to rule out firmware issues...though I don't know of anyone who has confirmed this type of symptom being caused by bad firmware) and grab an older copy of BBS that will continue to report stats when plugged in (or maybe it will still do this if you set custom ref? I haven't tried.) There is a wakelock that will show for plugged in...vbus_present I think it is. Or you can also watch CPUSpy - if it continually thinks it's plugged in you'll get zero deep-sleep.
Thanks everyone for the suggestions.i tried sering a custom reference in bbs but no luck. No matter what i try they all show zero seconds. If i look at the battery graph in the system menu, it says the phone has been charging non-stop for the past two days, which is not the case. I will try cpuspy and report back.
Get a tooth pick and push up or down on the metal insert inside of port. May take a few tries but will work. I believe it is caused by your chargers 5 little metal cables bent when you plug into phone...

BBS update
FYI - I just grabbed the latest RC for BBS, and it now has a toggle-able option to log stats while charging (with a caveat to use at your own risk...stats may be inconsistent). Might be another tool for further investigation.

I tried cpu spy. i left the phone untouched, unplugged screen off for about 90 minutes. Cpu spy shows the phone spent almost all of that time at 200 mhz, never entered deep sleep. So it does seem to be a hardware problem, where the phone thinks it is plugged in continuously. i will carefully try the suggestion above to straighten the pins inside the port..maybe they are bent and somehow shorting. If i screw up the port....well, i probably have to change it anyway

Well it's not my cable. What it does is act like it is connected with no cable being connected. Therefor causing it to act like it is charging. Then it prevents deep sleep and wakes and vibrates every so often. Really quite annoying and killer to battery life...

I have not been able to use my Transformer Prime for a few months now (I'm in the military) and obviously the battery died. The problem is, I cant get it to turn on at all now. The power cable connectors look fine, and it always worked before this. Does anyone have any advice? My Prime is rooted and running Virtuous Rom.
I would assume something wrong with the power supply or port inside the device. I have a prime that I am parting out if you need any parts. The only thing that is unusable is the system board on mine (due to a bad flash).
Best of luck figuring it out!
Well neither the tablet nor the dock are charging. Would that indicate a bad power cord more than anything else?

Normally I think it has to get up to I think a 5% charge before it will turn on but not sure if this is what you are describing or if you have let it stay plugged in for some time and it is not charging. That would seem like a hardware issue then.

So I have had this I9100 for about a year. Flashed with CM10.1 long ago and been reflashing new nightlies when i see stuff on the github log that address bugs I want fixed. Anyway the other night I put my phone charging, I didnt flash anything that night just a normal day. Next morning phone is dead. Wont charge, wont boot, no recovery no download mode, PC wont detect anything when I connect via USB. Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is.
So I searched for people with dead and bricked S2 and didn't find anyone with this problem, then I searched for people with other phones and again no one with this problem.
So I was wondering if USB jig would be able to help me, or JTAG, or if its just the usb board that died since it was while charging and it gives off no signal via USB to a computer and if I changed that it would come back to life.
What do you guys think? Was it the main board or is it just a fried USB board and the phone can't regulate power without it?
Sounds like the USB board, but you never know until someone 'qualified' has a look at it. We've had a lot of similar problems on here over the past two weeks (this week in particular I've seen maybe 5-6).
Doubt a jig or JTAG would be any good given it isn't a firmware type issue by the sound of it.
I guess I'll order a usb board a replace it. If it doesnt work its not expensive anyway. About $10.
I was wondering if there have been a lot of people lately with this problem could it have been one of the nightlies that screwed up power management and fried the board?

Yep if you can get a cheap one 2nd hand it's no great loss if it doesn't work & you end up needing to replace the MB as well. If you need them, I attached the SGS2 service manuals to a post of mine a day or two ago (click on my name & have a look through my posts over the past few days) if you need/want them.
That's an interesting theory. Not being a dev, I'm not up to spec on whether anything at, say, kernel level could cause something like that to happen (In the 18 months I've been here, I've never seen a kernel/firmware pinned down as the cause of something like this), but you wouldn't say it's impossible.

Did you try the ole toothbrush trick?? Get an old toothbrush and put it into the usb port an go mad. Sometimes a film can be on the terminals of the usb port, which gives you a bad connection.

With the multimeter check is there a voltage coming from the battery. The battery by itself!. Next leave the battery out from your phone and plug in your charger (which is connected to the wall). Put the multimeter across the appropriate terminals of the phone and measure the voltage if any.
Report any voltages values you have

The battery gives off a steady 4.
The phone connected to the wall without battery gives off 1.3 when first connected or the battery removed and then very slowly starts dropping to 0 going slower as it drops. By the appropriate terminals i imagine you mean the ones that connect to the battery wherethe battery has the + and - symbols.

That USB port is working, battery is fine. Next the screen might be dead. First check to see if the backlight is working. Turn on your phone as you would normally shine a light onto the screen and see if you can see anything. Use a flashlight or something with a high focused beam

So batery and usb charging normal. No screen problems, and heating cpu while off. Most likely main board fried? I'm gonna get some resistors to make a jig and try that anyway.

Yeah...that CPU heating is a worry.....it's obviously being forced to do something that it wasn't intended to do....and it doesn't like it.....
And with regards to changing the impedance of the jig....probably not advisable. ....micro electronics is very sensitive to resistance and voltage. ...what you're doing with the jig is essentially bridging two connectors. ...
Impedance too low....too much current/voltage passes.....things might begin to get hot (best case)
Impedance too high.....too little current/voltage passes.....no effect.....

Quick overview...been running hyperdrive rls7 with some mods and been running nice. All of the sudden today when I got in my car, the verizon charger that always works with my phone says its now incompatible and the battery is not charging. Got home and hooked up to various chargers at different wall sockets...same message. Thought it might be a rom issue but restored to just stock rooted and am getting the same message. When the phone was in recovery (twrp) mode however i could tell it was charging bc it had a "58 +" which means it was charging (also it was at 50 before I restored).
What is going on and is this just the phone not thinking its getting charged, when it really is? I've googled this and have researched a decent amount and most issues of this type are a device issue...not rom specific. I really dont want to get a replacement device that has ME7. Any help would be much appreciated.

I'm very careful when plugging my phone in since my wife has bent hers before. The only way that my phone seems to charge is if I revert back to rooted stock and throw the phone into recovery. The phone is recognizing that there is a charger plugged in. It's just saying it's the wrong one. I went to Android Phorums and it looks like several people over there are experiencing the same exact problem. It looks to be some issue with the motherboard. This guy replaced the "usp ribbon" inside the phone and that seemd to fix it...? Dont really want to open up my phone, but looks as though I might have to unless I want to restore stock rom and charge in recovery every night and then restore hyperdrive in the morning when I wake up (this is what i'm doing today at least)....

Link above goes to another android forum that shoes exactly what is going on with my phone, but the one fix that is within means me taking the phone apart which isn't something I necessarily want to do...please help...anyone...tried cleaning out the port on phone, but the device is rather new, so not much to clean.
Also, just tried letting the phone charge with the phone off, along with the gray battery screen and the vibration every 10 seconds on the way to work and it actually charged up by 4%, so it seems the battery is chargable, just not while the phone is on. Something is def wrong here, but all is not lost. Any other fix known to anyone other than taking my phone apart and replacing the "USB ribbon"?
Also, when connecting to a windows computer, the phone is not recognized...there is a usb connection in the status bar for just a second and then it goes away. Believe this is all hardware related, but dont want to trade or get replacement device since I dont want to be locked down.
Yikes! I sure hope this is limited. Sorry to hear about you (& others) having this though.
You may want to consider purchasing a couple of extra batteries and an external charger. Anker brand batteries on Amazon are reported to be as good as the oem battery. You can get 2 batteries plus an external charger for $23. Beware of cheap oem batteries. They are often counterfeits from China that are not very good.
Sorry to hear that your problem is most likely a hardware problem. Some people are comfortable taking their phone apart and some are not. You will need to decide for yourself if you think it is worth the risk. I hope everything works out for the best for you.

Yeah...that's what I was thinking aout regarding an external charger. The good news is, is that this phone has pretty good battery usage. Just not what I expected from a $500 piece of electronics after 2 months of use. Thanks for the Amazon info!
I prefer an external charger anyway. The phone does not get hot while the battery is charging.

Why not just revert to stock and send it in for warranty?

I believe the next to last line in the op answers your question. Chances are the update to ME7 would be installed by the techs. There is also the fact that it can take a while. I sent a phone to Samsung for warranty work last year and it took 4 weeks to get it back.

OK, so all of the sudden yesterday my phone started charging normally and connected to my computer as well. Basically, I think there was something wrong with my charging port, which has since fixed itself. Called a local service center and they mentioned that samsung ports go out all the time. If this happens to anyone else, not all S4 ports are the same...make sure you get the one for the Verizon GS4...
So this morning I start playing music on my phone as I'm getting ready to take a shower (shower off at this time) and then the music stops - of course, the phone doesn't respond to the power button. So, I've tried recalibrating the charging circuit and booting into hboot, but with no luck. The charging lights do not turn on and the capacitive lights do not flash when holding the power (or any other additional combination of) button. I'm going to leave it on a charger for a day or so and see if I can get anywhere then. In the meantime, is there anything else you can advise me to try? I've read that disconnecting the battery for a few moments might do something, so I think that'll be my next step if keeping it on the charger doesn't result in anything.
Any advice is welcome, of course.
Cheers,
Griffin
Yeah so far the only thing I have seen with people who have had the same problem were disconnecting the battery. Or most people just get a replacement.

So I disassembled it and pulled the battery for about ten minutes and reconnected it - to no avail. Is there a way I can test the battery? I have access to a multimeter, but I'm not entirely sure where to make contact on the battery's connector. I'm going to leave the battery disconnected for several hours and see what I can do then.
I seen in another thread like this about calibrating the battery but I can't find it.
to calibrate battery turn phone off and plug device into outlet press and hold power volume up and down at the same time until device poowers one or two minutes has passed if two minutes has passed call htc or asurion and replace it

Welp, battery disconnected for ~24 hours and then attempted recalibration - nothing. I think I've got a bad component somewhere in there. I'm going to take up Best Buy's blue HTC One for $30 on Black Friday, but I'm definitely going to see if I can find out what's wrong with this thing, this hardware is not going to waste!
Thanks for the advice everyone!
Try another charger, maybe the one you've been using is bodied.
The same thing happened to me, I used my warranty and luckily I had 2 days left. I think we should start to really look into this problem, because I see it popping up more and more, and it is kind of **** that one year after this phone came out and everyone phone is bricking with no easy solution.
Were you rooted/rommed and what rom?
Rooted n ROM has nothing to do with it charging

Mine crapped out in a similar fashion last week. Disassembled it yesterday and also had no luck with disconnecting the battery.
Anyone hook up a volt meter to these bricked phones? It might be a bad batch of batteries, or they just give out after a year of heavy to medium use. Anyone try a replacement battery? I am just hoping this phone doesn't randomly give out like this, but the trend seems to show sooner or later they just brick themselves.

I'm not sure if it is the battery specifically, yet.
Hate to necro a thread, but we're always asked to search, so..
Did you ever get this resolved, OP? Mine literally just did the same thing. I was watching a YouTube video and it died in my hands. Full battery, had just taken it off the charger like 30 minutes prior. Absolutely no activity, no lights, no flashing, nothing. Get nothing when attaching it to the computer, too.
I'm really hesitant about getting a replacement because I don't want to be somewhere where I NEED the phone and have this happen. I guess I'll get a replacement and sell it for another phone. Damn.
Disconnect it from the charger for an hour, then connect it to a charger and wait a half hour to see if the charging light comes on and then turn it on.

Tried it. I tried everything I can think of. I'm getting a replacement from Verizon and selling it for the Moto X. No way am I gonna risk this happening again.
This looks like some soft if hardware failure but no one has been able to tell exactly what happens. Sorry to hear this happen to you.

It happens so suddenly. The phone has been flawless since I got it. The only thing I can think of that was weird was a hard reset last week, but I just chalked that up to CM nightly issues. Oh well.
