myTouch overheats when plugged in; won't charge

When I plug in my phone to charge, the charging light does not come on. Within 2 or 3 minutes it becomes noticeably warm in the area below the battery. After about 10 minutes it gets very hot. No matter how long I leave it on, the battery does not charge.
I can turn the phone on while it is plugged in, but it will turn off within 30 seconds of unplugging.
I have tried 3 different wall chargers, 2 different USB cables on 5 different computers. I even bought a new battery. The result is the same every time.
Does anyone know what the problem might be and if it can be fixed. It is out of warranty, so I'm not worried about opening it up if there is a fix that involves getting dirty.
Thanks in advance!

Some more information that I've discovered since the first post:
I can charge the batteries as long as the phone doesn't overheat (in the fridge/freezer).
When I plug it in to USB, it will charge (as long as it doesn't overheat), but I can't connect it to ADB or mount the SD card. The computer doesn't really even recognize it most of the time. When it does it says "unrecognized device". FYI, I have used ADB many many times in the past, so I know it is set up correctly.
I'm not sure if this is useful information, but the SD card shows up as unformatted when I pull it out of the phone.
I realize that the problem is hardware, I just wish someone knew exactly what part of the phone was bad.

[Q] Critical battery icon showing when powered on.

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.

Phone doesnt reliably charge when connected to PC

Anyone else notice the phone randomly doesnt charge when plugging it into the computer?
The battery will say charging, the lock screen will say charging, but the battery screen will say not charging and the graph will show a green charging line but draining battery. Replugging the phone in fixes it. I havent had an issue with the wall charger.
Theres nothing wrong with the USB ports, it charged my other phone fine and it charges this phone when it works.

my N4 charges fast when I plug it to my laptop. I connect it to my USB 3.0 port..

PCs aren't designed to charge phones. It may work for a dumbphone with a 500 mAh battery, but it doesn't have the amperage to charge a smartphone efficiently. The charging adapter that comes with the phone is 1200 mA (milliamps), a computer USB port only provides 500 mA (on USB 2.0). On USB 3.0, it provides 900 mA, so it will charge faster, but not nearly as fast still as the 1.2 amp travel adapter.
On top of this, the phone is constantly using battery power while on, so it is very likely that when the screen is on and you are using the phone plugged into the computer, the phone is drawing power faster than the computer is charging it.

That is not what Im talking about. It says charging everywhere except the battery screen where it says not charging, that is obviously a bug. A computer can power a phone fine anyways, they are made to be powered by a USB port.

I had this problem today. The battery was dying fast (Average for this one) and I had popped it into my stereos USB, The battery didn't show the charging sign.
WTF? So I switched to the "Cigarette lighter port" and with a different cable plugged that in. No go. Held in the power button to simulate a battery pull, Still didnt work.
Turned it off, Went back to work and three hours later getting ready to drive home i plugged it in. The phone was getting warm, But the battery charging sign never popped up. I turned it on and the left side (By the sim card) was getting ultra-hot but betterbatterystats said the battery was only feeling at around 101degrees (Normal for this small sun). A minute later it was highly uncomfortable to hold (Just near the sim card area), I thought the battery was going to catch on fire like those youtube videos.
I power cycled once again, the battery charging sign popped up and I breathed a huge sigh of relief. Seconds later the phone ****ing flipped its wig, It kept making the charger plugged in sound and vibrate every half second. I about had a stroke, Thinking it's going critical. ONE MORE POWER CYCLE, Everything is normal.
My earlier experience seemed similar to yours OP, Let me know if your phone melts your hand off and goes all bi-polar like mine did.

I'm having the same problem. It has nothing to do with a computer not being powerful enough to charge it, especially when they aren't even being used such as overnight. It has charged every other smartphone that I've used. It will say that it is charging on the lockscreen and on the settings pulldown but it will just constantly drain battery. I will put it on the charger before bed and wake up 8 hours later and it says it is at 86% with a steady decline in battery. This only happens when connected to my iMac and not when plugged into a wall outlet.

I wouldn't think USB 3.0 improves the charging speed at all, since the protocol still uses USB 2.0

I just remove all the cables and replace them. It seems to solve it.
Same with the AC adapter. I noticed sometime it would say charging USB when I switched. I just unplug everything and plug it back in and it goes back to normal.
/shrug

I havent noticed it getting warm, it just doesnt charge even though it knows its plugged in and is supposed to be charging. It works after replugging it in.
It also seems to charge abnormally slowly.
I wonder if the issue with the phone not working right with Nokia chargers (constantly disconnects and reconnects) is related to this. It may not have anything to do with the Qi standard because the phone just doesnt charge right period.

[Q] Overnight: Charging to 100%, then discharging while still connected?

Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.

is this the only time it happened?

It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.

Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers

did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.

This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...

Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)

it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...

Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.
Are you using stock kernel?

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...

come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.

Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246

Axon 7 usb type c charging

I've bought an Axon 7 last month (A2017 Chinese variant 128gb internal 4gb RAM). One day when my phone was shut down, I inserted the usb type c into the phone's port to charge it and it vibrated and turned on and showed the battery and the percentage but it was not actually charging and the percentage didn't go up even 1% and as I waited longer it actually discharged 1%. I didn't have this issue before that day so I pulled out the usb type c and inserted it in again and I saw that it was charging normally.
Later I figured out that the reason of that issue was that I unintentionally inserted the usb type c in the port in two pushes.(I mean I inserted half of the usb type c first and then push the other half into the port) So I checked it out and I observed that when my phone is shut down and I insert usb type c in one fell swoop then my Axon 7 starts charging normally ,but when I insert half of it first and wait for just a second and then push the other half and all of it into the port, the phone vibrates and turns on and shows the battery percentage but doesn't go up even 1% and if I wait longer it will even discharge 1%. FYI I 've tried several chargers,quick chargers,cables and the one that came in the box but the results are the same so if it is a real issue,the issue is with the software itself. I hope you guys can help me with this and tell me the reason and if yours have got the same issue. I would sincerely appreciate any replies.(my Axon 7 is still running 6.0.1 and A2017V2.1.1B07)
