[Q] Charging and USB connectivity problems

Hi guys,
i have LT15i, baseband 70, Doomlord kernel (ICS, rel.v5) and MooDeD ICS 80.7 (ROM). I have 2 issues with my phone. When i connect cable to my phone (for charging) its charging for aprox. 30 minutes and after that its simply stop charching. Tried several cables, several adapters, several sources of energy (USB, tried every socket at house XD). And here comes second issue... after connecting phone to PC... PC shows my phone as Uknown Device and phone didnt even show that he is connected. I have tried several computers with different windowses. I also tried other ROMS, other Kernels but without success... Maybe i should change baseband ? Or what is the purpose of this stupid problems ??? PLS help me...
Thanks for all reply.

I think u should post this in chaosfirzen rom thread..then he would reply to ur question..:thumbup:

[Q] Note2 not charging, connect(ed) to PC.

Hi,
Yesterday my new (~2 months old) Note2 stopped charging. tried 2 different chargers, 2 different cables connected to PC. No reaction (no beeps, no led, battery icon not changed to flash).
Tried removing and putting the battery back in. No change.
On the other hand, when connected to the PC, the PC identified the connection and allowed file transfer. Later the battery died completly. I succeeded in booting to download mode, and again PC identified the USB device.
Switching the phone on with no battery gave no results either (would not turn on).
This leads me to a conclusion that the USB port is probably OK. Could it just be a dead battery? (according to its label, the battery was made on Nov 29th, 2012).
I will be able to switch battery tomorrow with another Note 2. Anything else I can try till then?
Using custom recovery and stock rom.
Thanks in advance,
Idan

U already tried all the possible steps... Did you try turning the phone on when connected to a wall mount charger ?

Yeah, with or without battery... no reaction from the phone.

Have you tried a lower powered device to see if that works? Some usb ports don't have full power output, as some laptops portray.

I've tried 2 USB ports on a desktop PC. didn't work.
I've connected it without the SIM and SD to an old nokia charger (0.7ma), no sign of a change but after ~ 1 hour I noticed the red led turned on - turning the device on showed 44% charged.
Now I am too puzzled. any ideas?

This is exactly what happened to me. .. it was the motherboard. I brought an external battery charger, charged the battery full so I could use the phone. Then used triangle away and odin to flash stock rom, and sent it in for warranty service. This seems to be becoming a common fault with the note 2 now....ive seen a few thread recently.

Hey there, my sgn2 n7100 had the same problem before, I tried everything, even disassembled the phone apart, but it was still won't turn on or charge, won't be recognized by pc or Mac. One day when I repaired my mom's iPhone 4 touch screen, I found out that the USB port was so dusty. I thought may be it's all because the USB port was dusty then I picked up my sgn2 and used a soft tooth brush with a little pure alcohol to clean every corner of the USB port. Guess what? After 15 minutes I connected my phone with the USB wall charger, my sgn2 just started to charge again. Trust me guys, try to use a soft brush to clean the USB port before you give your phone to the repair store or somewhere else. Good luck!! Hope it helps.

Same here, i manage to purchase note 2 for 300 euros! And when I put it to charge nothing!I went to download mode and then turn it on normal and its charging! Also happend the same with my s3 so eighter its a charging problems or seems to be one software issues

@scufutz I could guarantee the symptoms described by the OP is NOT software issue, as I have an N7100 with same problem and I managed to flash new kernel and still it does not charge even powered off. Download mode connects perfect.
I'll check if this cleaning method, or if its a circuit prob.

[Q] Sprint Note II Charging Issues.

Alright, I'll try to be as brief but detailed as I can.
I just got my note II 3 days ago. I used what little charge it had out of the box until it died, and plugged it into my computer to charge it overnight.
I woke up and it was fully charged. I used all of the battery and plugged it in to charge the next night as well. only this time, I woke up to find it hadn't charged a bit.
I tried to plug it in to a different charger, and I saw no charging icon. I rebooted the phone, and I got the charging logo. it only charged for about 10 minutes before it stopped charging. I tried to reboot it again and got the same issue. so I spent a while trying different chargers and cables until it was totally dead.
Now, when I plug it in I get a gray battery icon with a loading circle in the middle, and then it goes away. I tried leaving it for several hours like that, but it didn't charge at all.
I read on several sites, including this one I think, that it might be a software issue. I tried flashing to a stock recovery rom with Odin but that didn't do any good.
the weird thing is, I can get into the recovery menu, and let it sit there for hours, so the phone IS receiving power from the charger. it just wont charge!
I took apart the phone to check out the solder on the connector, everything looks perfect. I even sprayed it out with electronics cleaner spray.
I'm not sure what else I can do besides get a new battery, but I mean, this one is brand freakin' new!
What exactly does this battery icon mean? I can't find any info on it or anything.
btw, I still can boot into android, but it instantly dies.
thanks for any help!

I had the same issue about a month after I got my note II. I ended up having to take it back to the sprint store. They ordered a new one for me and I swapped it out once it arrived. It didn't cost a thing and I had a backup phone to use while my phone was dead. Check with your local store and see what they can do for you.

I bought my phone from ebay (new) so I dont think that will work : (
some updated info though, I charged the batter using a friends note 2, and it charged fine. I stuck it in my note 2 and plugged in the charger.
it says its charging on my phone. I get the charging symbol and everything, but it just doesn't charge. I'm really starting to think this IS a software issue. maybe I should try a custom rom.

Factory reset could help.

I tired that but it didn't help. : (

Charging the phone on the usb from the computer is not the best as the battery is a beast..... there is a reason the stock wsll chsrger is 2 amps .... most computer usb are maybe 1/4 that so that is probably your issue....

Like I said, I have tried many chargers. my Asus motherboard has a header for a 2 amp usb port for charging devices. that doesnt work either.
I have tried my friends note 2 charger and that doesn't work. my battery charges fine in his phone.
my port is working fine for data transfer. my phone shows up in odin as well.

Note that at stock the phone kernel is not written to make actual use of a 2A Usb line. IIRC stock kernel limits to sub 1A.

[Q] Phone Does not charge Note 2

Hello,
This problem started recent, that i can not charge my phone
when i plug it to my computer the charging led does light up,
it says charging on the screen but percentage does not increase. It decreases like it is unplugged.
If i plug to a wall charger, same thing happens (And even sometimes it doesnt say charging while on wall plug"
if I plug my note 2 to my laptop, the device does not show up on "my computer"
I'm pretty sure this is a software issue. This happened after I changed my ROM (This --> http://forum.xda-developers.com/showthread.php?t=2722002)
I tried to calibrate my battery with an APP but problem still exits.
--
UPDATE
somehow I was able to power the device without the battery, it was just plugged.
I was able to see Samsung screen. So, my device does receive power/current from the cable but does not charge
Please help me, I'm tried to swap batteries

First clean your usb port contract
Second Always Use LG/BlackBerry/Sony USB cables instead of samsung one.(specifically for N7100)

help, my phone stops charging

hello guys,
i need help figuring what is wrong with my phone. it cannot be charged right now, even when plugged in with charger,
the charger and cable i used dont seems to be the problem as i tested with my other phone too.
i have tried changing charging port and battery, but it still didnt solve it. so here i am asking for your opinions.
last week, my phone stops charging when plugged in and the battery wont go up when charged, i tried using same charger and cable to charge my other phone but those didnt seem to be the problem. after that, my phone eventually ran out of battery and died.
then, i thought my charging port has problem, so i buy new one and change the charging port.
but that didnt not solve my problem, as my phone did not even boot when plugged in and when i tried to charge it after that.
then, i assume it was my battery that has problem. so i bought new battery, fortunately, the new battery came in with 50% of battery juice. but after i try to charged it, the problem still there, the phone still cannot be charged.
this time, i checked with the ampere app for my charging status and found that when plugged in, initially the phone is charging, but after few seconds, the charging stops and it will repeat the charge-stop charge cycle. this is also visible with my charging led light.
however, i dont remember if this charge-stop charge cycle was there initially last week, i only remember it just stops charging, so i didnt know whether this is another problem or the same one initially.
things that i have also tried
1. i also tried changing the charging port to the old one and it didnt do anything, same as im using the new charging port. the problem still there.
2. i also tried using usb file transfer to test whether the charging port are problematic overall or just the charging part is problem. my usb connection has no problem as i can steadily transfer file for few minutes without disconnecting. so i assume my new charging port has no problem then.
3. i also tried flashing stock rom as i thought maybe kernels and stuff from custom rom messing things up. but it also didnt solve it.
4. i also tried turning the phone off and charging it, the phone boots up to charging screen, but the battery keeps dropping instead.
i dont really mind if this phone cant be saved anymore, i already backup important stuff from it, i just wanted to try fixing it for fun now.
also, english is not my first language, sorry if there are parts that is hard to understand.

Maybe some partitions are corrupted(like persist or any other)... search on xda how to flash those partitions. And try flash full MIUI fastboot ROM. Khmm if this doesn't work than I'm out of ideas. You can buy charger for battery only, for playing around until you gonna find a fix. Better than buying new one.
Good luck.
