I have recently had my phone charging port replaced at a store and when I plugged it in i heard a bit of a crackle and a popping sound. It was fine for a while but soon the phone started being powered, but rarely charged. The port seemed to work fine but just no charging? What's weird is the battery keeps charge as long as it's plugged in, it just won't take any more power in? Battery replacement? Or could this be the circuit board damage? Maybe even Battery and port replacement?
Thanks for any help in advance
Does the speaker work properly? Data transfers to and from home phone work? If not, could be a defective USB flex cable.

Hi everyone,
My first post as I haven't been able to find an answer. My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance

Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
Anyone? I still haven't been able to find a solution. I don't see pins touching, but if some pins are touching in the usb port, would that cause the heat issues when I put a battery in that I charged externally? I do get the green led light when I plug the phone in to charge so figure that means the usb is ok?

did you try a other charger ? do you have oryginal photon charger ? for me its not a reason of battery
regards
(in situation like that charging with normal usb cable when you plug phone to pc dont charging battery, you need motorola usb service cable to make it work)

Yep used the motorola cable that came with the phone (plugged in the wall and just the cable in multiple computers, another motorola house charger (the same as the one that came with the phone), a motorola car charger, and a samsung house charger.
When you say motorola usb service cable, I assume you're not talking about the motorola cable that comes with the phone? What usb service cable are you referring to?

factory / sevice cable ( i make my own from below tutorial)
http://forum.xda-developers.com/showthread.php?t=1077414
if you buy / make this cable , you will be have posibility to use RDS lite and flesh firmware this also make help (if you have low battery flesh with normal usb cable is not possible )
and second thing... maybe try some car charger ?
Hello, recently I'm having a problem with my Galaxy Core with charging!
This occurs randomly, few times only! Not always:
When I plug in the charger, as usual, it shows battery charging! Even after charging one hour, when charger is unplugged, the battery meter doesn't increase! I've tried restarting, cooling down battery, charging again, and it charged normally 100%. So, basically it does not bother me much, but just wanna know if this happens to anybody else, and as, I think, its a hardware problem, so I worry about it?
Another thing is if I connect my APACER B120 Mobile Bank, the phone doesn't charge, does not even show its plugged in. Other phones charges perfectly, even with the same cable. Has anyone tried charging with this, or any portable charger? Thanks!
sound like hardware problem man
Make sure your usb cable is working and use the cable you got with the phone.

I have only one cable, and it is the one I got with the phone. Cable works fine even on Tether/ReverseTether!
Posted this over on the timurs kernel Reddit but he wanted to get all defensive about it and deleted it cause his kernel is perfection in his own opinion. So I'm copying it and pasting it here. Just want any info on it I can get.
When I first setup my nexus I originally used my cigarette lighter worked fine then I converted to a dcdc converter and set it up for 5v when I hooked the nexus up there was a pop and a burning smell but every thing worked fine. Other than I noticed a horrible battery drain issue. After a few months I discovered anything I plugged in was draining the battery even if the tablet was off. The led on the phone charger would even light up even if it wasn't plugged into the wall. Got another nexus and everything worked flawless for months with the same DCDC and timurs kernel. Plugged it in took it out multiple times with no problem. Yesterday I decided I wanted to give marshmallow a test. It worked fine to other than it wouldn't charge due to the OTG cable and the way the stock kernel works so i flashed Element Kernel and enabled OTG charging and fast charge. It came on it charged and everything except music was playing through the tablet and not the DAC so I unplugged it and plugged it back in. It wouldn't charge..... Then I realized the charger had welded itself into the port and wouldn't come out. Finally got it out and tried it again. This time the tablet went black and won't do anything the port is melted on the tablet and the cord has melted plastic in the end. Is it a DCDC converter issue? Or a kernel issue? Maybe fast charge related? Just asking cause of the problem I had at the very beginning. Do you think the LCD might have survived? If so I was going to buy another nexus with a bad screen for like $25. Any input would be greatly appreciated just too keep it from happening again. Thanks in advance.
Fast charging burned cable? Ampere value?
You should put 'fast charging' in the title.
I used Timurs kernel on a 2012 Nexus 7 and the batterie was getting so hot, I had to disable fast charging. Since I used a Y usb cable to charge the tablet and only one usb device (usb ethernet adapter) there was no problem.
Maybe you should use an dc adapter with less Ampere output? Normal Charging is 0.5 Ampere but fast charging was up to 1.5 Ampere for me (checked with one of the cheap 'USB Charger Doctor Voltage Current Meter Mobile Battery Tester'). Maybe 1.0 Ampere is enough? Or use a thicker usb cable?
I think the LCD is fine because the overpower destroyed the mainboard only. But look inside the Nexus and see yourself!
Recently, my got hit by the floor i the back, and at this point every time i connected it to the charger it wouldn't charge saying it's cold.
I tried replace the wireless module, the battery and even the charging port module.
I also formatted the phone but nothing seems to be helping.
If anyone here has a solution for me, i would love to hear it.

Sounds like a hardware related issue.
Does charging via USB cable work? Or via wireless charging?
The phone says that it's too cold to charge? If it is not that cold, maybe the temperature sensor is defect preventing the phone from charging the battery

High g impacts can damage chipsets, crack solder joints and... thermistors. May be just a loose connector but it needs to come apart to be repaired.
Get the battery replaced while it's being repaired.
I need some opinions on what part to repair on my Poco X3 NFC. My story is the following:
One day, precisely 2 years and 2 months after purchase (so just outside of any waranty, grrrrrr...), my mobile stopped charging the battery with a normal 1 Amp USB charger. Only a fast charger with USB power delivery still worked. 5 charging cycles later the phone did no longer charge at all, it ran out of battery and couldn't be turned on again.
I changed the charging port PCB, which is quite cheap and for a few days things were normal again. Then the same thing happened: Only a fast charger with USB power delivery still worked. 5 charging cycles later the phone did no longer charge at all.
Now my phone is dead again. Since changing the charging port PCB with the IC was not the problem, what do you suggest to do next?
Had the same problem.
Neither new charging port nor a new batterie helped.
The problem was die Mainboard cable. It only costs a few euros/dollars and is very simple to change.
I don't understand how a cable which doesn't move can break but the problem was definitely the cable.

Do you happen to have a good explanation why this happened to me twice? What are the odds of "first normal charging breaks, then fast charging breaks a few days later"? And to continue speculating: do you think I need a new charging port PCB this time as well?
It looks like my charging problems are solved by using a new charging port PCB and cable. At least for now the phone is still charging. However, I seem to have problems with 4G reception after the change. Does anyone have similar problems? No 4G after charging port PCB change?
I had the same issue with not being able to charge. I also couldn't use the aux port anymore. I replaced the port dock, but happened to break the main flex cable so I also replaced that. So it could've been either.
My 4G is working fine. Maybe you messed up the antenna?
