Problem charging - dodgy usb port? - Galaxy Note II Q&A, Help & Troubleshooting

My phone is having some issues charging. Firstly I took the phone to Canada for a fortnight from UK. The phone charged normally for about a week and then one day the battery got very low (3%) and the phone would take a charge. I dont know if this issue was caused by using a plug adaptor or by letting the battery run so low?
When i got home the phone wouldn't charge from the mains initially, but i was able to get it above 15% using a computer usb port and from the on it took a charge from the mains.
As of today it is now playing up again, it wouldn't take a charge from the mains overnight, but I think it is currently charging via my pc, though it seems to require the cable be held at a tight angle.
My wifes galaxy s2 had the same problems as my note 2 in canada, but we were never able to charge it when we got back to the uk. I am looking into replacing the usb port for the S2, so i was wondering if this was something I should be doing for my note 2?
How long is the Samsung Warranty? (phone is 18months old)
Are the usb ports easily replaceable?
Anything I should know before doing this?

How much moisture do you think it takes to short out an electrical circuit?
For water to have gotten in the case far enough to damage the battery, it would have ruined more than that.
Did the phone stay on after you dropped it? Then no, it's not your battery.
Have you tried just letting the phone sit, off, and dry out, before trying it again?

Hi thanks 4 ur reply yes the phone stayed on after it was working fine till I put the charging in it. It would not charge the battery.
Just let it sit out over night...take the back cover off and battery out and just let it sit around...or if you have a blow dryer you can try that but dont put it to close

Good advice, but I'll just amend it to say ... ONLY when the battery is OUT. In fact, be sure to give it a few minutes after trying that before booting it back up. And, only point it at the back cover, it could easily have negative effects on the screen.
Hi appreciate the help everyone yeah I left battery out last night it still won't charge this morning, I am using the usb to adapter that came with the phone 2 charge it. This happen once with my HTC 8125 & I had to get a original charger to bring the phone back to life no charger will charge it but the original after u can use anyone, I will update u later and c how that worked out.
Hi guys on found this online on ppctechs.com it says "In some cases, your HTC Touch Pro 2 will not charge from an AC/DC adapter or other charging accessory when the battery life is below 30 percent."
Are you trying to charge from a USB port or an AC adapter?
Maybe the USB port is bad.
Do you have another charger to try?

Hi I try usb to adapter that came with the phone 3 different wall chargers and still not charging, last 2 try is a car charger don't have one and there is 1 ft of snow outside
Hi I ordered a new battery & a battery wall charger off ebay when I get it I will update u on how things when.
Hi I got the wall charger battery is fine I think I have a faulty usb port cuz the phone still won't charge or connect via usb can it be u need software to charge
have the same issue (didnt drop it in snow though) it won't charge via usb or car charger.
So you got a new battery and still won't charge via USB?
Mine connects to my pc fine, just doesn't charge. Ordered a new mugen power 1800mah battery, waiting for it to get here to see if its a battery problem.
yeah still don't charge plus it is in a bootloader loop think it is a hardware problem with the usb port
I know that, for example, the iPhone has about 4 moisture sensors, one inside the USB connector port, one in the headphone jack, and 2 inside the phone, the last 2 will trigger things like reboots or even blocking the charge. Put the phone in silica gel or, more convenient, a bag with dry rice (that's how I've saved my old lg vu) for couple of days...

Have you tried plugging it into the mains (wall) charger and let it sit for a while?
That fixed my bootloader loop, turns out the battery was too weak to power the device on that it went to bootloader. I Just plugged it into the wall charger and ignored it, came back and it was working fine and charging.
But it won't charge via usb or car charger
I had the same loop problem but mine never recovered. Never dropped it in anything wet either. I let it die once and could never get it to turn all the way back on because it would just try to boot and then shut off again over and over. Had to send it back for a new phone. If its new enough and there is no water damage marks then I would send it back for a new one.
Hi everyone phone is fix now it was a bad usb port that was causing the bootloader loop so protected your usb port.
I have a problem with my USB port too. Nope, no snow. Just realized one day why my internet kept getting disconnected. It's because the USB connection was the problem. Jiggling it around gets the orange (or green when battery is full) light to come on and computer will recognize it... or it starts charging from wall charger. I think the phone's USB connection is bad. Is this a common problem with this phone?

It seems to be yes, I've seen quite a number of people who've had this type of problem on the Rhodium end up finding out it was a bad USB port on the phone...I think HTC just might have used ones that weren't nearly sturdy enough.
USB Port of Kaiser TYTN II very sensitive to moisture
I have the same issue described here, with 2 different HTC Kaisers : (

[Q] evo charging problems

Ive had problems with charging since i bought it but i rooted so i cant take it in to sprint
sometimes it goes away though
i left it on for like an hour and it got to 16%
but now it was using the battery while it was charging because i turned the camera on just for one picture it was at 5%
is it suppose to be like this or should i unroot and try to take it into sprint
Are you using the stock charger?
Try plugging the USB wire directly into a PC/Laptop and see how it charges from there. If it charges normally, i'd say it's the main charger piece connected to the outlet. (The module between the cable and the outlet)
I've also gotten this issue 3rd party charges. The Evo is very picky on how it likes to charge =P

[Q] My N7 2013 stopped charging when turned on

Incredibly annoying. I got my device on launch day and have not had a problem. Never dropped it or damaged it or anything. Was running cleanrom 1.7 and all of a sudden the device stopped being able to charge while it was turned on. It charges fine when powered off.
I was using a 1amp power unit (ordered a 2amp power unit) to charge it. Worked totally fine up until a few days ago.
The device WILL NOT charge when turned on and plugged into my computer either (tried desktop and laptop).
Tried using multiple micro usb cables and wall chargers. I ordered a 2amp wall charger just to trouble shoot. I am not sure where the one that came with the device went.
I have read a few places that a 2amp unit is required (which is why I ordered one). However, I have never read anywhere that the device will not charge when plugged into a computer and powered on.
I flashed my device back to stock unrooted and still get this. Even relocked to bootloader.
Any suggestions? Should I send this device back for warranty? If so how do I even do this?

Roll back to stock and Unroot and send it for warranty!

Extremely slow charging with micro USB 2.0

This weekend I manged to leave my included Note III Micro USB B 3.0 charger at a friends. I didn't think it was a big deal because I knew I had plenty of micro USB 2.0 Cables I could use in the meantime as they are supposedly backwards compatible.
I was home watching football for most of the day yesterday. The phone charged all day yesterday but I don't remember it ever getting as high as 45%. I didn't get worried until last night when I looked closely and realized the percentage was declining as I used and charged it.
When I went to sleep at about 12:30am I was at 9%. My WiFi and 4Glte were both off and I wok up at 5:30 am to find my phone at 63% only after 5 hours. This is the same charger I used with my Samsung Galaxy S3 just over a week ago til I got this. Why isn't it charging. I'm afraid I'm harming my battery somehow. That's why I'm writing this at 5:45 am instead of sleeping. Any help would be appreciated. Thanks.
P.S. In the 10 minutes it's taken me to write out this thread my battery has declined to 62. (Still on charger)

I had a usb2.0 cable plugged in in my car and I went skiing and streamed music and did the same while plugged in on the way home. I don't know if the cable just slowed battery usage or not but it was plugged in for 2 hours on the way home and I still lost like 5% while plugged in. I bought a USB3.0 cable off Amazon and it works well in my car, not as fast as plugged in to the wall charger but much better than 2.0

I understand that 3.0 will be faster but this is horrendous. It's now 8 hours since I plugged it in and I'm at 74%. And it's plugged in to a wall adapter not a computer or car. Haven't even had this phone for two weeks. Samsung you're killing me here.

Not sure. My phone charges the same on both 2 and 3. I know data transfer is faster on 3. I don't think charging is.

It's not, at least, not from a wall charger that follows the specs. USB3 will charge faster from a computer with the drivers set up properly, but the stock wall plug is 2A (max), all the time. If you get better charging from a USB3 cable, your USB2 cable is probably using really thin wires or just is wearing out.
Some generic chargers are all over the place. Some don't short the data lines so the phone doesn't know if it should be able to fast-charge. Some don't actually put out the current they are rated for.
IF you use the charger the phone came with, and a GOOD USB2/3 cable, it will charge properly. If its not, you have something wrong in your setup. I use the charger that came with the N3 (and the N2), and a Nook or a Monoprice.com USB2 cable. Nice fast charging. I have never used the USB3 cable as I prefer to be able to charge other devices from the same cable and I don't own any USB3 computers.
I also get good charge speed from an older HTC 1A charger. Not as fast, but faster than I expected to get. Note that's a charger that came with a G2 and G2x, not some ebay crap. That's not to say that generic ebay chargers can't be good chargers, just that many of them aren't. If in doubt, use all OEM stuff, at least for testing.
What's probably happening for most people having slow charging on older and/or generic charging setups is one of these...
1) The charger doesn't short the data pins so the phone thinks it's connected to a computer USB and limits charge current to 500mA.
2) The charger doesn't output what the writing on the side claims, and the phone detects this, so it limits itself to charging as best it can.
3) The USB cable uses small, cheap wires and creates too much voltage drop, causing the phone to limit its charge rate.
4) Connector wear is causing voltage drops due to a bad connection. Try a new cable. Not a different cable, a NEW cable.
5) Your Note3 is defective and needs to be replaced. This isn't real likely, but damage to the USB port could cause it.
The Note wants a lot more current than older devices. It also has a system to detect issues that older phones didn't have. I think the first I saw with it was the N2. The phone detects voltage fluctuations under load and adjusts its current draw to keep the voltage as steady as it can. This makes the device more picky about having a good charger and cable. That can be a pain, but it also prevents overloading the charger, which could be something expensive like a computer, which prevents damage. Note that this doesn't harm the battery, it just won't charge as fast as you might like. At 500mA, it's actually possible for the phone to use more than that, so your charge will go down while plugged in. That's not going to hurt anything, it's just how it is.
For the OP: Try a decent wall charger. If you don't have anything better, you'll have to turn the Note OFF while charging. That should at least get your battery charged overnight. If it's a long cable, try a shorter one, that can make a difference. Or try to find a thicker cable, but that's not always a guarantee the wires inside are any thicker.

My phone won't charge with a long USB cable

I can't seem to get my Samsung Galaxy S6 to charge with a 10 feet USB cable. My old S3 do charges with it, which is weird. And I used to be able to charge it a couple of months ago. Not sure if it's a software issue. I think the SO was updated and not long after I couldn't get it to charge. I threw that cable and bought a new one. The brand is Anker, and they make good cables. I'm using a 3 feet cable of the same brand and model in the meantime to get it charged.
