I am on 137.35-5, unlocked/rooted and all has been working perfectly. Yesterday the phone powered down due to low battery despite being plugged into the stock turbo charger. After a little bit of troubleshooting, I've determined that the phone thinks it's plugged in (icon shows charging bolt, OS battery details shows "not charging"). In fact, even with the phone powered completely off and disconnected, if I tap the power button, it'll show the semi-circle battery status with a charging symbol.
I've used my air compressor to blow out the USB port, no change.
I've tried other cables, other chargers, no change
I've booted into recovery, where it shows "XX% battery" - though I don't recall if the charger is supposed to work when in TWRP.
GSAM shows it's charging with "calculating remaining time" never clearing.
If I leave the phone ON while connected to any charger, the battery will eventually die.
If I power off the phone, it will charge - about 50% increase in 8 hours (overnight).
Using a USB tester, I see that it's pulling 0.01-0.05a at 5V at all times.
I've attached some screen shots of the phone disconnected.
My next step was to do a factory reset (using the OS/GUI reset vs. Recovery) - but I figured if the phone-off screen is showing it's connected to a charger (without the phone even being turned on) then it's probably a hardware issue, no?
FWIW, yesterday, I plugged in a newly received OTG external camera (borescope from china). It worked fine on wife's LG V10, so I gave it a try on mine. It powered up, and the phone recognized it as a USB2.0 camera (though none of the camera apps showed an image). Perhaps that fried something?
Very likely a hardware problem. Turn your phone off, grab a toothpick and gently poke around the port, it could be that some debris shorted out the contacts. Also check if the "tongue" with contacts inside the port is bent downwards by comparing it to a port that works, a quick Google search showed that it helped a lot of people facing the same problem (link). If you follow the solution in the link, do it with a non-conductive object.
If it doesn't work, and you still have your phone's receipt, try flashing stock rom and recovery and relock your bootloader (if your phone is recognized when plugged in to the pc) and go to your service center for repair. Some service centers don't even care if you unlocked your bootloader before, especially if it's a hardware issue (check out this article, it includes a statement from Motorola, though I'm not sure if it's still valid since Lenovo acquired Motorola).
If there is no evidence that unlocking the bootloader caused the problem, you're protected by consumer rights in most countries (especially those in EU).

EDIT: My model is I9505
Whilst on holidays, I took my phone out of my bag (when I knew it was getting close to flat) to find it not turning on. I assumed the battery was dead, but when I plugged it into the charger it didn't charge. I fiddled around a bit, and eventually got the vibration and charging light - but it kept turning off before the green battery came on saying charging. Being on holidays I didn't have my USB jig, or even external battery charger with me. I assumed it was a loose connection with the charging port - as every time I tried to plug it into charge it would only sporadically say that it was charging - but never get past the picture of the battery and the swirling icon (prior to the green battery coming up).
Upon arriving home, I got out my external charger, took out the battery, charged it for a few hours, then tried it. Again - it wouldn't turn on.
I then tried plugging the phone in again - but to the 800mA charging doc micro USB, insteead of the standard 2 amp. Straight away I get the charging picture, and the little graphic showing me the phone is about 1% charged. I leave it, the screen goes off. I come back 15mins later, the phone is RIDICULOUSLY hot, and the screen off. I unplug and replug to find the battery is still at about the same 1% level. I turn the phone on - it boots, shows 1/2% and then turns off as soon as I unplug it from the dock - even if I plug it straight into a 2 amp charger. I now decide that maybe the battery itself is the issue - and it's not holding charge. So I whiz out and buy two replacement batteries (MPJ ones, as they were fairly cheap - and this was just for the sake of finding the issue).
I charge one for about an hour on the external charger (the phone didn't turn on when I put the battery straight in). Then put it in - same deal. Nothing. I plug it into the dock micro-USB out to charge - again it comes up as charging, and shows at about 1%. I turn it on, and again am shown 1/2% charge, and again as soon as I unplug from the micro USB dock it turns itself off.
It is almost as if the phone isn't taking any power from batteries, and only direct from the power outlet itself. I'm unsure what could possibly have caused this. I can only think it may have been an external battery which I was using for a while on holidays (which had a 1amp micro USB out, that I was using to try and keep my phone charged). That is the only thing I have done different over this period (at least as far as I can recall!)
So basically - in short:
i) Phone won't turn on unless plugged in to a low amp charger (Computer USB, dock micro USB out etc)
ii) Even after charging batteries in external charger (two different external chargers have been tried) the phone is showing 1/2% battery
iii) The phone turns off a few seconds after I unplug it from the power source.
Any ideas!? I will take the phone to get repaired after Christmas (if they still repair it, as it's running a custom ROM).
BTW. a USB jig worked for the first time this afternoon - when I tried it not long after taking the phone off the dock. It's also worth noting that the phone is ridiculously hot when on the dock (around the camera/sim/micro SD area).
Googling there seem to be a few in similar situations.

did you even try with a spare battery? can you check if your battery swollen? it might be the battery's fault

Hi, thanks for the response.
As mentioned in my first post, battery was what I thought was the issue at one stage, but I've tried two other batteries too. The original battery isn't swollen, but in any case I'm having the same issue with the other batteries.
I've tried charging them all on external charger before using them in the phone, and I get the same issues regardless of what I do.
It just seems strange that the phone switches on (now showing 0%) when plugged in, but not when unplugged.
And the batteries aren't being read properly, as they show 0% regardless of how long I pre-charge for.
Experimenting tonight, I've found that if I try to boot into recovery - even when plugged into dock, it dies before it even gets into recover.
Yet, if I boot the phone, I get to the main Android launcher/lockscreen before it dies...
Really has me baffled.

Hello again, if you have any spare battery and its has 50 or 100% try to reflash the rom just to see the results. or try a different chargers and cables as well, If it all fails, i think you should send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so your best option is to let Samsung handle it.

Thanks again for your response, but you're clearly not reading what my issue is before making suggestions. As I have now said twice - I have tried three batteries, and batteries that I have charged for hours on an external charger before using. But they still come up at 0%. Not sure how you imagine I flash a ROM
It may be a matter of taking it to my dealer it seems. If anyone else has suggestions before I get to that (after Christmas) it'd be much appreciated
The batteries fully charged on external chargers and I'm still getting the same issues.
I'm hoping it's not kernel related. Can anyone confirm that if it makes it to download mode Werth a jig (but turns off after a few seconds) that this would be a hardware issue? It only turns on with the jig when it's straight off the charger though - so seems it's still not using the battery for power, almost residual power somewhere.

In my view its a fault of charging IC . Since you have tried with replacing battery.

Sorry, what is charging IC? If it was a charging fault, a fully charged battery would work wouldn't it?
So I took my phone to my SP - Telstra. The phone, being only about 6 months old, was still within warranty period. Not surprisingly, Telstra have said that as there is a Custom ROM on the phone, the warranty is voided. I stated that my understanding is that under Australian law, as it is a hardware fault, and not a fault caused by the ROM, the warranty still stands - however Telstra wouldn't budge and said I have 5 days to decide if I want to pay the $300+ for the repair.
What is my next course of action? Has anybody had a similar issue previously? Is the TIO the next port of call? Or should I be going to NSW Department of Fair Trading?
I'm sure I've read previously that phones are still covered under warranty after rooting etc, if it can be shown that it's a hardware fault, not a software fault. As the battery doesn't seem to be powering the phone, this clearly seems to be the case - esp. as it is the same in download mode and recovery mode.
Any help would be great. Please don't post pointing out that I rooted my phone so THAT's my own fault etc. These posts aren't helpful, I already have know that.

So this issue happened out of no where after my phone died to zero last night. I tried charging it back up but all I could get out of it was the grey charging battery but it would only stay on for 1-2 seconds shut down and reboot. Let it charging for an hour and got to about 1-2% and it would die as soon as it booted up. Factory restored to OA6 and still see the same issue. This is also the odd thing... I was able to connect it to my computer and use Oden to do the restore! After lots of troubleshooting, trying 4 chargers, I realized wireless charging still works fine. Charged it up 100% over night and wireless charging is still working fine and phone is working fine. Still cannot get USB to be recognized while on either by computer or from USB charger. With a full battery, phone off, and USB plugged in phone still flashes the grey battery icon and reboots constantly.
Only thing I can think of is I had it in my pocket after spin class for a little and moisture might have gotten in the port?
Any ideas what happened here?
Update: I ended up just buying the Nexus 6P since I'm about due for a new phone anyways.
Well just figured I would pass this along. Was bored before and looked at diagrams to fix the USB board and saw this little port in the back you can access really easy. Decided to open that up and press the connection down a little tighter (the USB board is separate from the main board). USB didn't work before doing this, then pressed it tighter plugged USB in again and it worked.
So this is the second time this has happened to me. The batter will not charge at all. But I can connect to the computer with USB just fine. I've tried everything I can think of and it won't charge. The port is clear and looks in good condition. I've reflashed the stock firmware with fastboot. Nothing. The first time Moto replaced it on warranty even though the bootloader was unlocked. I tried that again and they sent it right back to me with the explanation that since the bootloader was unlocked they won't touch it, even for a fee.
So has anyone else had this issue? Is it possibly some sort of software issue that I haven't thought of yet? Or is it hardware and the charging part is different than the USB connectivity part? I only have about 5% battery left so I'm running out of options before I have a paperweight.
Edit to add: I've tried a dozen cables and no go. And all the cables charge all my other devices just fine. This isn't a dire situation as I was able to make a backup and restored the backup to a new X Pure that I bought but I'd like to be able to salvage this one to resell at least.
Any ideas anyone? Anyone ever have similar problem?
My old device that I sold to my cousin is having the same issue. It trickle charges on any cable, the included stock charger as well as the aftermarket QC chargers i'd used for a year before selling it. I backed his junk up and reflashed stock, same business, and I let the device die completely and charged it overnight to recalibrate, only got 80% in 7 hours with the stock cable. I'm topping it off at work before getting deep into troubleshooting, bootloader's unlocked so they'll probably shaft us on the warranty. I'll report back if I find anything out
EDIT: I've tried everything, completely wiping the internal storage and using the 5.1.1 return to stock package, charging in recovery and while completely powered off, and almost took the back off to try and disconnect the battery for a few hours, but they've got the back held on with Satan's glue. I argued with Moto's indian tech support for about 30 minutes, explaining how I'm positive that the issue is hardware related, and would be covered as the bootloader unlock only affects software installs. Of course, I know I voided my warranty by unlocking the device, and after enough badgering, they gave me a number to call on Monday when their service center opens so I can talk to a technician directly.
Further investigation has uncovered that the cause is probably the MicroUSB port, as the phone detects that it's "Charging over USB" rather than AC, like normal. Probably a short or something, but data transfer still works fine, as well as trickle charging.

Same problem here.....what I did was leave it alone and it eventually jumped back to AC charge mode. I did notice that it sometimes stays in USB charge mode it will die even though it says charging
Have had a stock Le Pro 3 since Dec 2016. No real issues prior to the last few days.
1. The device will only charge when powered ON. If powered OFF, the phone will vibrate once, the LED indicator will briefly come on, then turn off. Unplugging it and plugging it back it again does literally nothing--no vibration or LED indicator.
2. The device will not power on while plugged in. It will simply vibrate after a few seconds, then nothing.
3. The device will not connect to my PC for data. Have tried four different cables without success. It will charge from PC, however.
4. When connecting to USB and powered ON, the phone will vibrate and show the battery charging indicator, but will then hesitate slightly (battery charging indicator turns off), then shows the battery charging indicator again. Not sure if that means anything, just seems odd given everything else.
5. USB headphones do not detect/work.
6. The USB to 3.5mm adapter for headphones does work.
I've tried a factory reset to no success and have ordered a replacement USB C board just to be safe (it was $5 shipped), but am at a loss as to what to do. Tempted to let the battery drain completely and see if that puts everything into working order, but as it's my only phone, that seems a bit risky if I can't be sure it will ever start charging again while powered down.
Anyone here run into these sorts of issues before and any advice if you have?

A $5 board will not solve your problems. It will likely get you into deeper trouble because it doesn't support mtp and otg. It's only good for charging.
Your connector is probably damaged. You can try contact cleaner/lubricant on the connector. It may fix your issue. Something like this https://www.electrolube.com/products/contact-lubricants/eml/contact_cleaner_lubricants/
I use lubricant often on usb-c connectors even if they are working. Just extends the lifetime of connectors, the pins are really small after all so the contact surface is not much.
Replacing the usb-c board is not an easy task. You would need to remove the screen etc.
Hey everyone, it's my first post here and I'm glad to meet you all.
Recently, I updated my SGS7 edge using OTA updates and it failed to turn on after(stuck on bootloop on samsung logo). While i managed to turn it on after wipe in recovery mode, battery percentage decided to drop to low percentage (not sure what exacly, but to the point I decided to charge it). It shows alert about wet USB port, and I'm sure it wasn't wet at all, but I decide to stop charging and let it dry for few hours. Battery lost its charge completly while it was drying. After few hours i pluged it again, and it was charging (at least i thought so). After 2 hours of charging it managed to charge 1% of battery and then it turn off. When I measure the current flow to the battery it shows 90mA when I plug charger, then it drops to 0 mA after few seconds. When I press buttons it shows that current is flowingh again, but never more than 90mA. Anyone knows what can be a reason for such behavior? Is it charger port broken, or firmware malfunction?
EDIT: I've trierd to charge it for a bit with power button pressed. Now it shows that current is equal to 170mA and it keeps flowing without button pressed.

The way you've described it almost sounds like a short. It may also explain the difficulty with OTA (short). The S7 USB charging port may be suspect but also the battery may be at end of life. To eliminate the other usual suspects, have you tried a different USB cord and/or charger? Does your S7 show as connected when plugged into PC (either through adb commands or file explorer)? Have you tried charging using a wireless charger?
If needed, the good news is charging port isn't too difficult to replace, granted you have a heat gun and a few tools (google S7 teardown -- iFixit or youtube). If you're convinced the port is bad and decide to replace it, might as well replace battery too (OEM only). After the above mentioned process of elimination you're left thinking software, maybe download model specific required firmware (matching current binary) and familiarize yourself with ODIN flashing.

I managed to charge the device, I left it plugged into charger with power button pressed and it started after ~2 hours. Now, I'm trying to charge it to 100% just to backup my data. Really appreciate your help tho.
I was trying 4 different USB cables, 2 chargers and powerbank. Device wasn't recognized by computer by any means. I have no access to wireless charger unfortunately. I'm not gonna replace any part of it becouse it is time to change it to newer model I guess.

Hopefully all is well then. I wouldn't rule out repairing the S7E, it's still a competitive device. Newer phones are fine if you can afford it but I prefer proven devices with development and software support. Granted, it is a personal preference. For the same price of a new flagship phone I can justify to the wife fiddling around with 5 or 6 old ones (ha):laugh:. Other than an LCD/digitizer most parts can be gotten pretty cheap and there's always [insert any online sales (ebay/swappa/amazon)] in order to acquire a salvage device for parts.
