[Q] Phone not charging, even with AC adapter?

Hey,
(I tried searching for similar threads, but "charging" and "desire" gives me billions of results)
I have quite a sticky situation on my hands. Last night when I were to check my phone for messages, it was turned off. I grabbed my charger with the AC adapter and plugged it in. Voilà, amber led is turned on. I waited a while as I went off to grab food and that sorts, returned and turned it on. No problem so far. Small digression: I even got those messages I expected, hooorah!
Anyways, after a couple of hours I returned to my phone to check additional messages but then again, it was turned off. Even though it was hooked up to the AC adapter. I mean, the amber led is turned on and even the battery animation in the status bar when charged is doing its thing.
So I started trying to figure out what it is, but nothing have helped the slightest bit so far. I tried flashing different radios and roms but the problem seem to stick.
What's odd is that it allows charging sometimes, but it takes a long while. I have yet to find out the reason for it, but my doubts are that currently the phone needs to be off.
So far I think it could be a faulty USB cable that may cause the problem, but even though how obnoxiously stupid it may be, I turn my ears to you guys.
Thanks in advance.
TL;DR:
The phone isn't charging even though it's hooked up to the ac adapter and both amber led and animation in the status bar is indicating it's charging.

first things first,
search xda-developers re: USB brick. does it fit the symptoms?
do you have access to a different usb cable? does it charge better from this one?
will it charge quicker on on (for instance) your computer, compared to the wall charger?
is the charger an official charger or a third party one? if its a third party, no name brand one, chances are its crap. I bought a 1000mA rated car charger and one of the components won't let more than 100mA through.

Greetings, nzdcoy. Thanks for quick answer.
Let's see. As far as I can tell, USB brick symptoms sounds like you're unable to connect your phone using USB when booted into Android and/or custom boot/recovery. I have yet to try this, but I also read that they were able to charge the phone without problems. However, I'll give this a try seeing as it won't hurt.
I'm afraid I do not have access to another USB as these "micro" USB cables aren't that widespread. Or, at least I don't have leftovers as I do for regular USB cables.
It's hard to tell if it charges faster for whether possibilities as it doesn't charge at all if it's on. The amber led is lit, but the battery percentage still drops. I've only relied on the wall charger as I know it supports more amper than its PC counterpart. But yet again, I should try the USB brick fix. Hopefully it'll work.
Both the charger and the cable is stock, so I don't think it could be shabby third party components.
I'm also suspicious to if it can be the battery that's blasted. I've measured the voltage and it seems to be fine, so I don't know for sure. Maybe it's bad because it takes ages for it to charge? I don't have an external power supply, so I can't test this for sure though.
Anyhow, thanks nzdcoy for giving me some directions to what it could be.
Edit: Tried hooking up the phone to the computer, and I had access to the SD card. I suppose that's not a USB brick then?

at least it isn't a USB brick.
Does it positively charge when plugged into the PC? Unless you are using GPS or you are using a USB1.1 port, your PC should still charge it positively.

Yes, thankfully.
I've somehow found a method to charge the darned phone. And I could almost conclude it's a bad connection between the wire and the phone. I think the socket on the phone is damaged. Worst part is, is that it comes and goes. One day it could work swimmingly and charge in whatever position, the other day it requires one certain position to charge anything at all.
My Desire works in strange ways.
Thanks for the help so far, nzdcoy!

[Q] Phone won't charge, but...

A few hours ago I noticed that the phone wasn't charging even though it was connected. So I did a few experiments: I put into into three different power outlets, I tried a different charger, I connected it to the computer but nothing happened (the computer didn't even recognize it). Then I decided to turn it off and try again, and these are the results: the screen turns on really often to let me know that it's charging, there's even the charging animation, but if I try to turn it on not only it isn't charged, but it doesn't seem to recognize the charger anymore.
There are a few other weird things, though: I use the XenonHD ROM, and once or twice when the phone was unplugged the battery icon was still "moving" as if the phone was charging, but the graph said that it wasn't. This probably is just a bug, but maybe it meant something.
My best guess is that the micro USB port is broken, but maybe you guys can help me with this?

Just like you said, your usb port is broken, propably a short circuit somewhere. But changing the charging port flex ribbon is very easy, even for a first timer (like I was/did a couple of weeks ago)

And now the phone charges if it's turned off... but it's not like I can keep it like this, so I'll take to technical support tomorrow. Do you think I should flash the stock ROM and/or lock the bootloader?

Note 2 charging complete randomness - bad port?

Hey guys:
I'm an IT tech and I'm really confused on this one. Started happening a week or 2 ago. I'd be charging my phone and it'd randomly cut out. I run Carbon ROM and have the notification light set to be a solid yellow when charging so I know if it's charging or not. It would happen very infrequently, but would cut out. I'd unplug and replug and it would be fine for the most part. It's gotten progressively worse. I was running NEAK kernel so I tried to go back to stock Carbon trinity kernel, same problem. The other day my phone would also randomly go in and out of "car mode" too which was weird. Currently, I have it plugged into my computer so it's charging in USB mode (lower voltage) and as of right now it's holding charge. But prior to last rebooot it was going on,off,on,off with the charge. Today my phone has locked up a few times when plugged into a full AC charger even. Seems to be completely random right now. I'm just looking for any advice. Going to flash a different ROM and see if that does anything. If not, what part would I need to order? I saw a Youtube instructional video on how to replace USB port and I'd be willing to do that. I bought my phone off Craigslist and have had it for like 6 months. No proof of purchase, which you need for Samsung warranties right? The battery is not "swollen" in the middle. Oh, also this morning, when it was going in,out,in,out,in,out constantly (on full AC charger), i could actually HEAR the (official Samsung) charger resetting itself almost, in sync with when the charge would cut out, if that makes sense. I could actually hear the charger making a "click" everytime it would lose charge then it would try charging again, and would click off again, over and over. Lastly, today I also saw in settings->battery it saying "charging" even though the charge light on my phone was off AND i saw it drop a percentage so it wasn't actually charging. VERY random. Maybe clear battery stats? Doubt that'd do anything... I have CWRP on my phone...
Any thoughts at all on this or if you've seen this would be great. Likely new USB port needed. Where to buy? If new ROM does not fix, it must have to be replaced. That's all I can think of....

Currently, it is holding a charge. I re-installed NEAK kernel, and set the AC charging to 1000 instead of the default of 1700. This happens though. When it seems to be holding, it's fine until I unplug and try later and then all the randomness begins. No idea what to think of it. Don't even know if setting to 1000 had anything to do with it working, likely not....

Didn't see it mentioned. Have you tried a different cable or even a different charger? Would do that before changing a usb port on the phone. Doesn't sound like the port if you are able to charge via a PC USB.

[Q] Charging problem, tried the following...

Ok so a little of background story, if you don't care about it just skip to the next paragraph. I bought my T989 over the internet, it was working perfectly. I wanted to make the most of it, rooted it and tried Swapper 2, which hard bricked my phone. I'm not new to rooting, I've rooted some phones now, but I had never tried swapper, I liked the idea of unoccuping some RAM memory. Apparently I did something to my boot sequence thing and my phone was dead. I still had waranty on the phone (one week left when that happened so it is suspicious to anyone) so I called. After one hour of arguing over the phone and trying to convince them it wasn't my fault, which of course I knew it was, they decided to send me a new one... ahem "new" one.
Ok so here's where the priblem start. My "new" phone was working alright untill it stopped charging, didn't work AT ALL. I took a peek and one of the pins on my phone was bent, it was upwarda and as I tried to get it back to its place it fell off. I took my phone to get the MicroUSB replaced andsure enough they did.
My phone was charging again correctly. It was doing great untill it stated to charge slower and slower. It got to the point where it just shows as charging, but doesn't charge at all.
I've tried everything, I bought a new original Samsung battery, still same issue. I downloaded an app to tell me the amps the cellphone was pulling and it shows 350-450 when I have read it needs minimum 600. I have tried custom roms, kernels and nope, still pulling 400, tried LG chargers, Motorola chargers, a SAMSUNG S3 charger and still no luck. The thing they all have in common is that they're USB chargers so I read if the cellphone detects it as such it would give me a hard time.I've tried making a fast charge USB cable with a video on Youtube but it still only charges 400 mAmps. I've installed custom kernels with the "USB fast charge" and STILL no luck.
The ONLY thing I haven't tried is using and ORIGINAL, Samsung wall charger but at this point, I think it won't fix my problem because of the fact that I remember it worked well in the beggining. I am currently charging both batteries with a Universal Battery charger, but I've read that they wear out batteries throughout time.
So, is there another thing I haven't tried... or is my cellphone doomed now? I believe that it's the phone, as in the mother board if I can call it that, or does anybody have another theory?
Thanks for your time, would love to see anyone suggest

I know this isn't an answer but a general comment. This is a good reason why I will NEVER buy electronics that are used or from a retailer that isn't a big name. I don't care what the seller says there is just really no way to know exactly what you are getting. If you had bought this phone from Amazon (direct) you could have already got another one by now with no arguments. I'd be looking for another phone and call it a loss.

Thanks dude, I know it really matters on where you buy it, but the price was just so handsome to me. I guess that's what I get and as things like this happen you learn more and more on what you buy and what you decide to do with them. I guess I already consider it as a loss but I'm aware that it's not unusable yet. I guess I will continue to charge both my batteries with the charger, but I was just curious to know what really happened to the phone to avoid things like this in the future

What apps do you all have installed on your phone and running while you are charging it? Try making a full backup then do a clean install of your ROM (backup just in case this doesn't fix it). After doing this do NOT install any apps, just test charging. If charging works, it is some app on your phone. I know those "battery saving" apps can eat up a lot of battery if configured wrong. And if you have a lot of background apps running, they can eat your battery without you knowing and reduce charging time.
Go into settings->device and check what is eating up your battery there before charging and during charging.
If you don't want to re-install your ROM, try charging your phone with the screen off (no screensaver (daydream) or nothing, just screen off, charging) and in airplane mode. I recommend doing a clean install to see if it is some apps (you can use TB to back everything up, then do the clean install and test from there).

Can you go into settings->Battery and post a screenshot of it? I'm curious as to what is eating up most of your battery.
After, I would still try doing a nandroid and flash your rom cleanly and install 0 apps and try charging on this clean install. I know my friend ended up getting some battery optimization app installed (which she claims she never installed, but it is on her phone) and her charging times were horrid. It also made the phone quite laggy. I imagine if you got 2 or so of these types of apps on your phone, it could eat your battery instead of charging it.
Also, when you charge it, it is a strict charging cable not a MHL adapter right? I know when I have my MHL cable hooked up to my phone it claims it is charging, but it actually drains the battery slowly. (MHL is micro USB -> HDMI).
Since you have tried multiple chargers and cables, I would be looking at the phone as being the problem. Also, look at the contacts on the bottom of the phone and look for any bent pins. I wouldn't try to fix that yourself, but if they are bent, I'd take it in for repair. those pins are very fragile once bent and can break off if not handled very carefully after they are bent.
If you can get into adb from your phone to PC, then the pins on your phone should be good and the USB cable should be good. Does it charge if you put it in fast charge and plug it into your PC?

The pins are alright. As I stated, I recently changed the MicroUSB port, well I paid somebody to do it and it was working fine at first but then stopped charging, well, not stopped charging actually. At first it started to charge slower and slower untill it got to the point that it just says it's charging but it doesn't charge. It COULD be to the fact that I flashed new ROMs, downloaded games and all but I doubt it since now I have a brand new ROM with no games (or not that many) and you can see from the screenshots I uploaded that nothing's eating my battery
Well except for my screen, I had it at 80% brightness lol. Usually I set the brightness at the lowest (no Auto brightness to save battery) and my wall paper is color black since I heard Samsung phones do save up battery with black since it doesn't light the LEDs or something like that.
And yes, it's strictly USB cable. When I activate "Fast charge" and if I connect the phone to the computer it just shows the notification "USB connected" for a second and then disapears.

the screenshots attached were helpful. I don't see anything in that list that looks like a huge battery sucker and since you say your rom is fairly fresh and clean, it likely isn't the apps. Are you sure the guy who swapped the microUSB port did it correctly? Improperly soldered pins (especially those tiny ones on a microUSB port) can be tricky to solder correctly if you don't have the correct tips. It could also be that something else got damaged while putting that on (if the capacitors were not properly discharged before replacing the microUSB port, they could have gotten damaged).
I think that your assessment that it is one of the boards (likely the charging circuit) got damaged. I'd go back to the guy who replaced the port and get him to check the charging board (specifically the capacitors) to see if there is any signs of damage or wear. Capacitors can get damaged really easily if the heat on the iron was set too high. I know I've damaged capacitors while soldering things before. Or it could be that the port didn't get a solid solder connection or ended up briding some pins. If fast charge is on, your PC shouldn't see a USB device being plugged in. If you have a multimeter, you could check the resistance on the 4 USB pins and see if any of the pins are bridged.

Well I took it to the guy from before and he couldn't find a problem with the phone's soldering, but even he wasn't sure what the problem was as if it's not his specialty. I do not have a multimeter :/
I was thinking taking it somewhere else and have them change my microUSB port to see if that other person might now a bit more. I'm sorry but I'm more of a software type of person, I clearly have no clue what the problem might be
THANK YOU for really helping me and taking your time to analyze my question, I really appreciate it thanks man
So if what you say is true, do you think it can still be fixed?

It definitly can still be fixed, it'll just be tricky. If they are surface mount capacitors, which they likely are, it is hard to tell when they go.

So what I should tell them to do is to change the capacitors? I can leave the same miniUSB port right?

I would tell them the symptoms and let them tell you what they think should be fixed. In my mind it is likely the capacitors on the charging board that need replacing, but without having the hardware physically in front of me and hooked up to a multimeter, I cannot say for certain. It could be a faulty microUSB port or a bad pin (bridged or microfractured), could be damaged PCB trace, could be gremlins
I would bring it in somewhere or give it to somebody and tell them that the phone doesn't seem to be taking a charge and ask them if they can look at it. If it is still in warranty, send it to Samsung to get fixed. If it is outside of warranty, take it to somebody who knows their stuff (likely a professional repair shop OR somebody who does cell phone or PCB repair for a living... hobbyists may be able to fix it, but to me this sounds like something that somebody with training should likely look at).
Since you have tested different AC adapters (including known-good ones) and different cables (including known good ones) and charged the battery outside of the phone, that narrows the problem down to being something with the phone. You narrowed down it is likely not software related, so that leaves hardware. I know from experience soldering very small components can cause bridges quite easily; even when done by the pros. Some bridges don't matter, but it is better to avoid solder bridges whenever possible. I know I had to replace my nintendo DS slot-1 due to a busted pin and soldering that thing with a large iron was a pain in the behind. Got it all fixed, but it was not an easy task.

You narrowed down it is likely not software related, so that leaves hardware. I know from experience soldering very small components can cause bridges quite easily; even when done by the pros. Some bridges don't matter, but it is better to avoid solder bridges whenever possible. I know I had to replace my nintendo DS slot-1 due to a busted pin and soldering that thing with a large iron was a pain in the behind. Got it all fixed, but it was not an easy task.

This gives me new hope, I really don't mind charging my phone this way, but I'd rather have a complete phone with the ability to charge from a wall outlet
Thanks so much, I hope I can count on you if I run to anything else. And hey, you learn something new every day, ALL of this has been really helpful

Glad I can help. I used to work professionally soldering tiny components before moving into IT. Done some hardware mod to a few cameras, repaired a ps2 controller, have an old tube amp going fix soon too. I've seen a lot of weird things happen with bad solder joints or faulty capacitors.

Fast Charging No Longer Working

I wanted to share this in case anyone ever experiences the same problem. I had my Note 4 since it was released in October and didn't have any issues until roughly a week ago. All of a sudden, the phone would not fast charge. Whenever connected to the fast charging adapter, it would detect it and charge, but it would not give the fast charge notification and would charge extremely slowly (8 hours to get a full charge from near empty). In addition, my PCs would no longer be able to access it and the phone would not give the MTP option menu when connected. I tried multiple cables, outlets, fast chargers, and batteries in addition to toggling the fast charge setting, wiping the cache, and performing a factory reset - but nothing helped. I finally called verizon and they sent me a new note 4 and everything was working again.....
Three days passed and the same exact issue occurred again on the replacement phone. This makes me believe that the Samsung charger I have has somehow deteriorated and is now breaking the usb connectivity on the phone. I contacted samsung and am getting a replacement for the charger and will have to get ANOTHER replacement phone from verizon (after they finish processing my first replacement).
So if anyone has a similar issue, I would suggest getting a new charger in addition to the phone replacement so you don't have to go through the entire process again. I could be wrong that the charger caused this, but I can't think of anything else besides the recent lollipop upgrade - but everything was working for several days on lollipop for both phones.
If anyone has ideas on how to fix this, please let me know. I can't return the second phone until the first one is processed so no fast charging or PC connection until then. Thanks

Having exactly the same issues. Let me know if you work it out.

Same Issues and I have three fast chargers so it is not the charger it is the phone or the 5.0 update.
Mine was not really even charging unless I turned the phone off. I called Verizon and they are sending me a replacement phone overnight. It would not connect to the computer either. I hope this is not a result of fast charging, if so they are gonna get a lot of phone calls

I also have another fast charger which wasn't working... I was thinking that my main charger was breaking the phones USB connectivity and fast charging, but if others are having the same problem then I am wondering if it is something related to the lollipop update. I am replacing the main charger and should have another replacement note 4 come Friday. If it happens again, then I think it points to the lollipop update since both phones had this issues days after lollipop was installed.
I'll let you guys know the outcome

Had the same issue. Used a different wire. Solved the problem. Any Micro USB that can transfer data, can use fast charge. If it's a "power only" cable, or if the data pins/wires are messed up, no fast charge.

Well the problem was that all the cables were working and then stopped. When I got the replacement phone they worked and then a few days later the same thing happened again. So something was causing the connection to break completely. I am hoping that the cause was the charger which I am replacing.

Word of advice: if it stops charging normally In ANY way. THROW AWAY THE CHARGER. I made the same mistake and my Note 4 literally lit on fire melting the lower 1/2 inch of my phone and completely melting the charger. It was so hot by the time I was able to yank the cord out both the phone and charger were melted and destroyed and I ended up with three fingers with minor burns. I am lucky it did not happen when I was sleeping with my infant nearby. I now charge my phone only in the day and on a granite counter in case of fire again.
It stopped fast charging. Then I used the charger again and got a message saying "Transferring power to high powered device" then wham 2" flames
Verizon kept claiming it couldnt happen and thought I used a aftermarket charger until I brought the phone and charger to a corporate store and they prompytly replaced both the phone and charger under factory warranty.

I have three samsung original fast chargers and none of them worked plus the fact that the phone could not be connected to any computer I have makes me think it was the phone. I got the new phone today so I guess time will tell. I just can't see three chargers and cables going bad all at the same time. I also did not take the 5.0 update on the new phone.

my replacement phone stopped fast charging and computer will not recognize it now. I used a different cable that was plugged into the fast charge module from Samsung. I guess that is what caused it. They are sending another phone but for C sake if a cable is the reason this happens surely there should be a fix without replacing the phone time after time.

I finally received the new phone from Verizon and I replaced all the cables I was using to make sure this doesn't happen again. Hopefully the charger was the culprit and the problem is over and done with. Hope no one else encounters this as it really was a pain to deal with.

I got my third phone Monday and so far so good. I had a car charger from Verizon plugged into an extender that had 4 plugs in it. When I unplugged my GPS from it I noticed it was very hot. The Verizon Charger was also hot even though nothing was plugged into it. This may have been what caused my issue. It could have overheated. I replaced it with a different brand and tested to make sure it stayed cool when anything was plugged in and have used it all week without issues. The only other thing could have been the USB cable I used the evening before the second phone stopped fast charging so I do not use it either. So if you use a car charger extender check to see if it gets hot when anything is plugged in. BUT, it is scary knowing something like this can kill the USB on this phone.

I have an external Hard-drive that would constantly disconnect and reconnect with the slightest movement of the cord connected to the computer. It even caused my H/D to get corrupted twice requiring re-formatting. But all I had to do to fix it was to squeeze the big connector on the cord a little and tighten it up. Just a thought.

It's been a week since I received my third phone and everything is working perfectly. I can only assume the charger was breaking it and I'm glad the issue is behind me.
So for anyone experiencing this, I suggest contacting Samsung to replace the charger before going to your cell provider to replace the phone

I'm having the same exact problem. My 2nd replacement phone is now doing the same thing as the first one. I have too many scenarios now though and I'm confused as to which it is. I have two Adaptive chargers.. Batteries, phone, or chargers...

As soon as I replaced the charger, I didn't have this issue again. I suggest sending your chargers back to Samsung (or whatever other brand you have) because one of them is breaking the phones

I would place my bet on a bad cable. With the higher voltages that fast charge uses going through the danger of arching and sparking is increased especially if there's a poor connection would fry or weld melt metal inside the connector. This could damage the USB port in the phone and cause the phone's USB port to have a bad connection. This bad USB port in the phone could fry the other cables as well leaving you wondering why everything went bad all at once

My phone will fast charge on my two vehicle chargers (at 1.5 amps and 2.1 amps), but refuses to change any faster than 500 mA on two separate fast charger bricks. The same bricks work fine for fast charging other phones, so it's my phone, not the charging hardware. I'm using the same cable(s) for all instances, which leads me to believe that something is wrong with how the phone interprets the "smart charging" signal on the bricks, or that the phone is sending the wrong charging signal.
I can still connect to a computer just fine, so my issue may be different.
Does anyone else have the issue with bricks but not with chargers without "smart charging" capabilities?
I've had this problem on stock 5.1.1, Jasmine rom 6.0.1, and now CM13. I full wiped everything when reinstalling, so either it's hardware, or an issue propigated through many roms. I've tried a few different kernels too, just to see if that was the problem.
I'm changing the battery tomorrow to check that possibility. Maybe I'll bend the contact a slight bit and see what happens (phone catches on fire)...

Hi guys
I have the same problem as you ,so what I have to do to solve this issue without replace the phone,

Turns out one out of the three new cables I bought didn't work, and my OEM cable didn't work for fast charging. Swapping for a good cable fixed the issue.
