N750 refuse to charge. - Galaxy Note 3 Neo Q&A, Help & Troubleshooting

My N750 with stock ROM 4.4.2 refuses to charge normally. The led was off which being connected to USB wall charger. However it showed a grey icon battery for two seconds before the screen was completely off. I noticed the error message popped before this happened (quoted below). It said something related to Samsung power sharing software. Later on I found out the charging problem.
Power Sharing, You must download the app in order to control the amount of power shared. If you connect your device to another device with the Samsung Power Sharing Cable EP-SG900 without the app, the entire battery amount will be tranferred to the other deivice. Connect to Samsung Apps and download the application.

Strangely I did not use power sharing and honestly I don't know what it means and I wasn't doing anything or plan to do things with power sharing. The screen was a little shaky when the error appeared although seconds after that the phones worked normally except I cannot charge my phone. I understand that the phone might still have received current from the charger however small, especially when I charge it under recovery environment which is inconvenient to do. It took 4 hours to reach less than 30 percent under Phil'z Recovery method.
I tried to clean the micro-USB port with a small sharp needle but have no luck. It looked clean to me. I also wiped the data and did factory reset and tried to use different ROM. But still it won't charge. I also tried to use different cable and different AC Adaptor (Sony original charge 2.5 volt) which was working under normal condition but not anymore. I never drop my battery and always recharge before reaching 30 percent. That's my ritual as I read from battery University that frequent charging is much better than letting the Lithium battery goes down to near zero.
Any ideas?
I tried different ROMs to find the best. Is it possible that Samsung crippled the phone after so many reflashes? This is scary.
(UPDATE) The phone is NOT detected by Odin and flashing is not possible.

Broken USB/charging port?

I'm not sure if this is the right place to ask this, please excuse my ignorant.
I have an EVO that won't charge. I've read a lot from Google search results that this is a common problem among many users. However, the port seems to be working, because my computer will recognize the phone and storage when I plug it in. The charge led will come on, and the indicator on the phone will say that it's charging, but the phone is actually only discharging while plugged in. Eventually the led will turn itself off, and the phone stops telling me that it's charging when the battery is down to its last drop.
I hope that someone with similar problem can help me with fixing this, or if anyone cause tell me if it's possible to fix? I want to send it in to HTC since I think the phone is under warranty, even if I don't have the protection plan from Sprint? The problem is the touch glass is cracks, and I don't know if they'll fix the USB port without saying that I broke it and won't cover that under the warranty. I want to buy a new screen and replace the broken one, but if I open up the phone it would void the warranty as well...
So I'm stuck with a discharging phone, cracked screen, and having to carry around 3 separate batteries everyday, and I have no idea what step I need to take.
Please help?
Have you tried plugging it into another charger? It may just be the charger that is screwed up. If this behavior pattern is consistent across multiple chargers then you may want to talk to Sprint to see what options you have.

Doubt it's the charger as it was stated that the computer connection works - should get a bit of a charge from that. I agree that a Sprint visit is due.
Just went through this myself! Would plug my phone in before bed and wake up with the phone at 2% or so. Thought it was the battery- so i took my battery to have the sprint store check it, they did say it was bad. So i bought 2 batteries off ebay.
I got the batteries and still had the issue. So then I took my phone to the sprint store and had them check the micro-usb port. They said it was fine and they cleaned it out cause dirt/dust was in it. Still had the problem..
So I bought a new micro-usb cable of monoprice (still using the same wall charger) , and that solved the issue! Had a bad cable. Now my phone charges super quickly in matter of 4hrs.
It could still be the charger. The USB cable sends data and power through different pins. So a bad cable could still transfer data while not pushing a charge.

It's gotta be the port happen to mine and I was able to get it fix as long as the port was still attached to the motherboard, if its not attached then have to go thru the insurance.
EVO with Identity Crisis
I was able to connect to my computer and send data just fine with the old (broken) usb cable.
I've tried three different cable and a car charger, same result; they all say the phone is charging but it only gets discharged. USB/storage connection works. Last time the Sprint store said the battery is faulty, but I have 3 different ones and neither will get charged with the phone plugged in, an external charger will work.

Definitely sounds like a port issue then. If you return to Sprint and review what you've done, as well as the result of your previous trip, then they should be able to take care of you. If they try to tell you it's the battery again just stand your ground. Good luck.
I had a similar issue. I tried everything. It wasn't until I found my HTC cable that it started charging again. I work in IT and tried cables from everything I could get my hands on (blackberries, external drives etc. ) The cable that came with my phone was the only thing that worked.

If you replaced the port yourself, I would love to know how to do it!
Took the phone back to Sprint and they said there's nothing they can do. I don't have the protection plan so I couldn't even pay the $100 to get it replaced (although I probably wouldn't as I can upgrade my contract and get a new phone soon). They also told me that HTC wouldn't cover it under their warranty because the screen is cracked and they will blame that on me for misused. I tried to check the warranty policy on HTC, but the page is not even available. Does anyone have experience dealing with HTC? I bought a replacement screen, I'd like to replace the screen but don't want to open up the phone if there's a chance HTC will fix the USB port...
HTC EVO 4G Won't - Stopped Charging Battery Issue
Hey Guys,
Two nights ago I woke up to an EVO that was plugged in with a Cellet
extractable charging cord, as it is just about every night. But, the phone was
still showing that it was charging the battery, animation with lighting bolt,
at only 50% charged after about 6.5 hours of charging. Hmmm....
The latter after trying to charge in the coffee shop first with Cellet chord in the
wall then a portable 3500mah solar portable charger; the phone not seeming to
charge at or past 50% charged.
My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA
update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The
phone has only been rooted for a few weeks, but I don't see where rooting
would interfere with battery charging.
I've pulled the battery out, several times to no avail. Switched back to the
stock battery, same results. However, if the battery is less than 50% full
the phone will charge the battery to 25% or 50%, weird. If the battery is
at 75% or more full, the phone will top off the charge to a green LED at 100%,
sometimes. Sometimes it won't fully charge the battery. Weird.
I read different posts regarding poor USB chords so I pulled out the stock
micro USB to USB, a charge only chord I figured, and am trying to top
off the Seido battery, which it seems to be doing as it's now full green but
still charging as the animation shows the bolt in the battery and the LED
is still orange.
If put the batteries in the Seido wall charger, the thing the size of a deck
of cards, both batteries fully charge.
I also use Screen Off by Iwashi Soft. That app has worked pretty well with just
a little funkiness now and then. However, while plugged in, I hit the power
button, instead of the home button to turn on the home screen. The phone
wouldn't open to any screen nor would turn on or off. So I ended up
yanking the battery to turn it off then reinstalled battery and turned phone back
on. I don't know if that had any effect on the charging issue, but I took
the icon off the homescreen and am using the power button only, for now.
I don't think both batteries are faulty at the same time at this point. I
don't know if the screen off app caused some wake issue that interferes with
charging the battery.
I do know that when plugging in the phone to charge there's a bit of clunkiness
initially as the phone locks for a second before allowing use for screen or app
and that's always been the case since the gb update. Also, the LED doesn't
always turn green from amber when fully charged with the screen off until
you reboot or use the phone in some way while still plugged in. So there is
some kind of wake issue in the stock ROM. But the latter has never stopped
the battery from charging.
I do know that Plume, the twitter app, started acting clunky with not updating
in the background unless I opened the app at least once after a reboot. But
I don't know if the latter is a wake issue.
Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,
Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the
phone mostly in standby with periodic email and twitter reads, the battery lasts
all day or more than 24 hours. But the latter rarely happens anymore because I'm
a user.
The battery just went full charge with the stock charging cable just now.
This morning, I woke up with a dead phone, auto shutoff even though it was
plugged in which I did after solitaire and before going to sleep; as a charging
test.
I don't know if it's the phone or the Cellet retractable cord or both that's
stopping the battery from fully charging normally and consistently. I'll need
to get another data-charge combo chord and do more testing; and a new ROM.
Any ideas anybody?
try a new rom and also try using the stock charger and usb cable. Check inside your usb port on your phone for dust as well. Also go into recovery and wipe your battery stats. In the wipe menu for amonRa and under advanced (maybe here, i dont use cwm on my phone) in clockworkmod. also wipe your dalvik-cache just to clear any issues you may have, restart and give it a test. good luck
I just bought a phone with a broken charger port. Broke clean off the board, so my next step is to try to get liquid solder and stick it to the board. Did you take ur phone apart to see if the port is lose?
So I used the stock USB charging chord. Sure enough, it charged the phone.
Then I tried the portable charger at the coffee shop, worked. So the Cellet retractable
chord obviously had a short or something damaged/shorted for the charging part of
the cable after a year + of use and abuse.
What I don't understand, and haven't researched, is why there are charge only
chords; the stock USB HTC chord charges the phone, but the PC won't recognize
the phone's Micro SD card or the phone as an external drive. I presume the duo use
chords have a data path as well as a charging path. And yes, I know to switch the
phone from charge only to disk drive. The Cellet chord would provide the PC with
recognition for the phone's drive.
Considering the latter, what I'm not sure of, and haven't researched, is why when
the phone stopped charging, the chord eventually stopped charging, the phone
status still showed it as charging; the amber LED light on and the battery icon
in charging animation with white bolt showing? I presume that the charging path
still triggered the charging status, except once when I turned the screen back
on the battery icon was not animated and the white bolt not showing so I unplugged
the chord then plugged it back in where the battery icon animation continued.
Fortunately, or not, this forum returned 600+ results for 'battery not charging' and after
sifting through a few, the charging chord was mentioned which prevented a Sprint trip
and me contacting Seido; thankfully.
So I think manufacturers and ROM/kernel developers should visit this issue as a chord
that actually is not charging, or charging at an absurdly low rate, should trigger some alert
and not show a battery icon animation that appears to be charging normally.

HELP phone not charging.

So this is the problem: my ZL displays the charging light, it appears to be charging, but does not charge. I always had problems with charging, having to wiggle the connection or something for it to work, but not this type of problem. Sometimes it goes up for like 1%, then down again, wiggling between 10% and 20% battery. This happened in the last 3 hours, i switched cables, wall plugs, etc. Still the same. What can i do? When i keep it plugged it does not discharge, but i'm afraid that if it gets to 0%, it'll die. What can be the problem? Please help me

Dont worry frnd.
Need some inputs before i zero down the problem
1) Are you using the stock charger that came with your phone. If so there is every possibility either the charger head or usb cable has gone faulty.
2) Type *#*#7378423#*#* and goto battery test and check its health condition. If it says condition is good then the fault is with your charger
3) Try using a charger which is a 1500ma charger.The normal charger supports only 800ma/500ma so your mobile will not be able to draw enough current from it and usually takes more time to charge or the charging rate with be equal to the discharging rate like in your case.
Hi,
I had the same problem just recently - phone wouldn't charge to above 5% or so (if I was lucky) - all original charger. When I plugged in the charger, the led light flashed red, then another color (green or yellow, can't remember), and then it didn't charge.
I actually had some problems with charging a couple of times before - it went on and off like 5-6 time, but then it did start to charge normally after a while. This last time, I tried to charge it for hours without any luck.
If i booted it up, it sometimes charged to 4-5%, then it would stop/start/stop/start endlessly. The same thing happened when I connected the phone to my computer, the USB fell off/on/off/on endlessly. I thought it was a faulty cable / charger first, but this happened to all cables and chargers I tried. I then thought it was the USB-port on the phone. Or a faulty battery.
After a while, it mostly stopped at 1-2% - sometimes immediately. I noticed that after using the "battery button" to hard reset the phone, I always seemed to get a few %'s of charge, and it didn't just blink immediately when plugging in the charger.
I had even written my problem description and was about to send the phone back to the retailer, when I did one last try of factory resetting the phone from the recovery, wiping everything. The problem still existed when I booted the phone, however, entering the recovery again after factory reset - I actually noticed that the phone charged above 5% this time. Leaving it on charging while in recovery, it got up to 8%, and then I thought the problem was fixed. Booting again, still same charging problem. I then factory reset again, and tried recovery again... Leaving the charger on - I managed to charge it to 100%. After this, I've never had any problem charging the phone. :|
I don't know what solved the problem, it could be only charging from recovery, or it could be that the full wipe deleted some battery stats or something? I did install an app to wipe battery stats after the problems occured, it also showed the charging rate of the battery, and it went up and down like crazy when I had the problem.
I don't really know if this is of any help, but I had PhilZ recovery at least which I managed to charge with.
You can try any methods, but i realy think that it because bad accumulator.
- original chargers
- hard reset
If it is not help - your way is go to the service.
Usually it the problem with accumulator or power controller.

[Bricked] Flat battery, Won't charge, No recovery, No root

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated
What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??
The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it
I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !
The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.
http://www.amazon.com/gp/product/B007IXBTCK/ref=oh_details_o02_s00_i00
This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

I have the same issue.........!!!
I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........
Anyone??? Please???
With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?
Sent from my SM-G900I using Tapatalk
The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.
Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing
Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.
I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V
From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?
Thanks for your info lecorbusier
With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.

Unexpected symptoms, need help assessing and figuring possible solutions

First time posting , I guess, usually I just browse through for info... but now I feel a bit in a dead end.
Spent a few days snowboarding with the phone in pocket, so exposure to cold subzero temp. lowest around maybe -10, only symptom during that period was camera started flickering showing purple lines but worked fine later on.
Also had trouble charging one night, as phone spent entire night being plugged in only to show it was discharging the whole time, and battery low in the morning, couldn't get it charge even after cleaning port making sure its clean and dry.
Phone ended up running out juice and powering down completely... it didn't respond for hours (tried different chargers) but than suddenly the power bank I use showed it started drawing about 9V and 0.1/0.2A for some time and it slowly started drawing more power and charging to 100% took more time then usual...
Next time I tried charging it when it became low around 20% it wouldn't charge from the wall charger or battery charger.
Tried a lot of resetting, rebooting, but the battery just started dropping really fast each reset.
Plugged it in and tried the volume up/down, power button reset but all that did was a multiple resets and still wouldn't draw charge from anything.
In the end it just stopped responding to anything.
I would show a few orange flashes when I plug it to something and than stop.
Tried leaving it plugged in all night but nothing. Leaving it alone for 3 days also did nothing.
Then it stopped even showing the few orange blinks.
Current status:
Plugged it into computer usb and started showing orange flashes, decided to leave it plugged in.
Showed on screen the battery and 0% after a few min. Screen brightness increased after 20min.
Now its been 3h and its still only showing 0% for battery and flashing the orange light every few seconds, nothing else.
Will go to sleep now and leave it plugged in computer all night.

Have you tried a different USB cable & charger?
There have been numerous reports in these forums concerning charging issues with the device. If you've cleaned the USB port on the phone and have tried multiple USB cables and chargers, then most likely your battery is the culprit and needs to be replaced.

In a lot of cases they managed to restart the phone...
Yes I did that. Phone is still showing 0% battery after being plugged in computer usb, I find it funny how it wasn't responding at all to the wall chargers. Now for the question of the day, can I have the battery replaced without losing data? I asked a service center that kinda could be a HTC representative but cannot confirm it and they insisted that they have to do factory reset.

Can you charge the phone up and get the phone to boot to TWRP? If so you can mount your phone to your computer and back up all of your files on your internal storage to your computer.

I don't have TWRP but I just did manage to enter the stock recovery? and its just sitting there not really charging up but using 9V and 0.4A to stay powered up in that mode.
Can you tell me if I go to service center to get the battery changed will I lose all data by default of that process?

I wouldn't think that merely changing the battery would cause you to lose your data, or why they would do anything to your phone that would wipe your data from the phone.

Alright, that was my primary concern, thank you. The service sector where I live is pretty bad, and they do stupid stuff, follow stupid rules.
Update: I switched through a couple of chargers, and tried going into recovery after which I initiated a restart, phone booted normally and showed 24% battery, now is connected to original QC 3.0 ... and charging up, but stopped after 1%, I unplugged it and plugged it again and it continues to charge now with steady orange light? this is really nerve wrecking... what is the real issue? battery, charging port?
My goal is to try to charge 100% back up everything and then I can send it service.

Phone will charge quickly when fully off but will not charge when on

I have been having this issue for a few days where the phone will detect the charger and it will display the charging sign. However charge wont go up and in fact sometimes it goes down. This problem however doesn't happen when fully off and works as usual. I've used ampere to check and noticed i only get about 150ma where as before i would get constant 1500ma. I tried different plugs, different cables, software repair, hard reset, safe mode. Nothing works

I was able to get just charging working (slow charging) when the phone is on by filling the battery to 100% when off and then leaving it unplugged for a few hours after that. I then turned it back on, used it for a bit until it reached about 70% and then charged it with the phone on and it began to charge again ( its pretty slow compared to fast charging but its a start).
Other possible solution.

I read somewhere that a corrupted SD can cause this issue too so I also removed my SD card when doing the process i mentioned above. Not sure if this is what solved it but you might wanna give it a try.

i dont think so. may be problem with the charging connector. there is possibility to poor contact between connector and PCB board due to solder connection or may be possibility of loose connection between connector and charger pin . so slightly press the charger pin and connect and now then its charging . just try
Works
I don't know which of the two methods it was but fast charging became usable again and works fine.
