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 ?
After doing some extensive research as to why my Nexus 5 was randomly off when at full charge I discovered there were obviously alot of issues going on with this.
After doing all of the suggestions (e.i. Charging for an hour with standard AC, An hour with USB) I finally got the thing to turn one *whew*
Well not so *Whew* after all. The battery indicator in the tp left of the screen is saying the battery charge is empty. The charging level also says %0. As soon as I unplug the charger it turns off due to lack of charge.
Did the factory rest thing and it's still doing the same thing.
After some experimenting I have discovered that while in the boot screen (Vol+/Vol- & Power) it does not have to be plugged in. Interesting.
Every time the phone gets to where you can see the battery level it thinks it has no charge and auto offs itself.
What do I do?
I would first try a different charger. Its possible that you have a bad charger/USB cable. If that doesn't work then I'd send it back and get a warranty replacement phone but more than likely your issue is a bad charger/USB cable and if not that then a bad battery.

6 months ago i noticed my tab wasnt charging when the charger was plugged in, so i opened up the device and saw that a little wire of the battery was broken (maybe coincidentally). I bought a new battery but my tab still wont charge. It DOES charge (very slowly) when the device is turned off, but when it's on it doesn't charge neither will the PC recognize it as a USB device. If the charger is plugged in and the battery level is low, I'd unplug it and the low battery message would pop up. It's like the device recognizes I plugged in the charger but some way it's not able to charge. I'm using the original charger. What should I do?
Ok this is weird and only started recently
I plug the phone in, it reacts to the charger, the battery signal shows it's charging, it says charging on the lockscreen, the settings/battery says charging AC but the phone doesn't charge at all.
EDIT - turns out my power brick is dying. Used a friends Samsung brick from his S5 and phone is charging quickly. Guess my old trusted 1A power brick just couldn't handle it anymore and decided to die a slow death
I have not used Android in a couple of years so excuse me if this was an old feature.
This morning I was going to use the quick charger supplied by Google to charge my phone before I left for work. My phone was still in Do Not Disturb mode. When I plugged it in and it would not charge but it recognized there was plugged into a charger. It looks like it was just providing enough power to keep the phone charged at the current level (mine was at 60%). The second I turned off Do Not Disturb it started charging again.
This seems like a good feature. You can plug your phone in overnight it will maintain the charge instead of continuously charging the phone and potentially shortening the battery life.
You encountered a bug. I leave my pixel in do not disturb permanently and it charges to full. I have encountered the issue you describe and unplugging the charger and plugging it back in caused it to charge to 100%. It would be silly to tie charging to do not disturb as an actual function.
Probably just a matter of wiggling the wire. When the USB-C plugs are new, they can take a bit more than the expected amount of force to seat fully in their socket.
