About a month ago my Note 4 stopped charging properly. I thought the battery was just getting on in age but with some troubleshooting I've noticed some symptoms-
#1- No longer shows up as Fast Charger plugged in. Whether it is Quick Charger, Regular 1A Charger, USB cable to Car Charger- it always shows up as USB Charging. This takes about 8 hours for a full charge.
#2 - Phone no longer connects to computer via USB .
#3 - Today I attempted to put a Wireless Qi Charger in, and while I was able to get some charging on a friends note. My Note seemingly is unaffected, even though the Qi Charging comes from the back plates- NOT from the USB port.
I'm guessing my 'charging unit' is damaged. Though I'm willing to hear out any suggestions.
Can anyone think of any components that would make this so?
Right now an external battery charger seems the only reasonable fix.

I'm having problems with kaiser charging when using HSDPA and even slow connections like 3G and EDGE.
Problem is that it charges for about 20-30 minutes (connected to a powered 1Amp USB hub or even with AC charger), then charging light goes off and battery power starts to drop by about 5% every 20-30 minutes.
Have anyone tried 2Amp chargers? It seems like it may be the problem with kaiser itself, since it charges itself but then just stops and will not charge itself until I soft-reset it.
PS: it gets kinda warm, but I wouldn't call it hot. Dunno if its related to temperature.
Any ideas?
Am I the only one with this problem? If so, maybe I should return the phone and exchange it for a working unit?
No, I have the same problem here.
When I use my kaiser in the car (usually navigating) the orange charge light initially lights up, but after a short period goes out. When I disconect and connect the USB-cable, the light temporarily comes on again.
I am using a 1A car charger. I do notice the charger feels a bit hot when in use, so maybe the kaiser is drawing more power than allowed? I can imagine the charger overheating which causes the voltage to drop. Which probably causes the kaiser to stop using USB power. But this is all speculation.
I am planning to use a 5A voltage regulator to 'upgrade' the USB charger, and see if this solves the problem.
--After a bit more reading, I found some info about the kaiser detecting if it is connected to a charger or a USB host device, and regulating it's maximum charge power accordingly. So I will try a modified USB cable to let the kaiser know it can get 1000mA from the car charger.
It's not the USB charger. I have 2A and 3A Olympus Camera chargers that I modified to use as a USB charger. Also cheaper 1A AC chargers. I thought the Olympus chargers would be perfect, because they were high amperage, and built solidly. I had the same charge problems with the TyTn II, and an iPod Nano. They would either charge partially and then stop, or not charge right away, but the charge light would come on after awhile. But still only partially charge.
My guess is that the chargers that work may have a load added in, so that the switching regulator will turn on with any additional load from the device, and stay on. I never found any information on this, though.
What does work: The USB chargers made for any PDA phone. Apple iPod chargers. I bought an 800ma iPod charger (probably a clone). It's a small white cube, with a USB outlet, and interchangeable AC plugs. It charges the Nano, and the TyTn II OK. The Nano last for a week now, instead of 2 days. The TyTn II starts charging right away, and stays charging. So whatever the Apple USB chargers do, they do work.
A thought for the car is to get a car charger made for the iPod, and see if that may work.
To be more accurate, the iPod charger starts charging the TyTn II right away, and the charge light stays lit. I've not actually done a controlled test on it. Just charged for awhile, and verified that the charge light comes on right away, and stays on. Everything looks normal, though. I will try a more controlled test, and post the resutls.
please keep us posted. I've also contaced HTC support about this, I'm waiting the response. Once I found out I will post here.
Hopefully iys not a ksier limitation.
Test results.
Battery at
- 61%, Display off while charging
- 83% - after 70 mins of charging. Then stopped, as was going out.
Started again at:
- 88%, Display off
- 100% - after 60 mins. A little shorter, probably, as I missed when the charge light went green.
I believe the PDA will fast charge up to around 80%, and then slow charge for the remainder. That would explain why it takes 60 mins to charge from 88% to 100%.
So, the iPod charger works great for a PDA, and will start charging right away when it is connected, and it will charge to 100% full charge. It is not the PDA that is stopping the charging. It just has special requirements that only some chargers can handle, so you have to get either a charger built for a PDA, or something like the iPod charger.
So it works quite well as a general purpose charger for iPods, and for the TyTn II, and probably anything that uses a USB charger. It is small, with interchangeable AC plugs. A good travel/general purpose charger. I can bring just this, and different cables for different devices. Phone, MP3, etc.
It is labeled Input:100-240V, Output 5V 1A
Looks like:
Apple MA592LL/A iPod USB Power Adapter
Just as an aside, I have a lithium battery pack 2 7/8" x 2 1/8" x 1/2" thick. It is rated at 2400mAh, input 5V, through a built in retractable USB plug. Output is 5V 450mAh through a female USB plug. Just extend the USB male plug and plug into any USB source to charge it. It works quite well as a small portable battery pack to power/charge a PDA if using GPS steadily. It's flat, and easy to carry.
And it is quite cheap.
ttt123, thanks for your info. I guess I need to get an iPod charger then.
What's the deal with the battery on this phone. It takes several hours (3-4) to go from (near) 0 to 100% charge, with USB.
And, when using navigation on the phone, with a car charger plugged in, the phone still loses a little bit of charge. All other phones I had, they would charge somewhat slowly with the GPS on (since GPS is using draining a lot), and never seen one that loses charge even while connected.
I have tried 2 different car chargers, both aftermarket though. Do you see the same?

Most of the car chargers only deliver 500mAh - when your phone is plugged in, go to settings-> about phone and see if it says AC or USB charging. You also need a car charger that is rated at more then 500 mA.
But even with a charger rated at more then 500mA - the phone still thinks it is plugged into USB. I got around this by modifying a USB cable - I connected the data lines together on the micro usb end and the phone thinks it has AC power and charging keeps up with GPS.
BTW I am using a 2 port car charger (2 1Amp USB ports) Griffin I think, but i tested with many others, and after other internet searching realized the wall charger shorts the data wires and we can mimic this on a car charger.
alphadog,
Thanks for the reply.
Can you give more details on how to connect the data lines together? And, no issues doing that?

No issues for me. First - use a decent USB cable. Also, see this thread for more info... one of my posts is page 2. Page one shows you an easier hack for testing - no cutting required.

I took a USB cable and did all my work on the micro end - where the connector for the phone is. I stripped back some of the outer insulation, so i could work on the inner wires. I didn't cut the whole end off. The two wires that are not red and black are the data wires. I cut them, stripped them, and soldered them together. These 2 wires are from the micro plug end, so i created a loop back or connection of the 2 data wires at the plug end.

So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!
On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.
Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.
Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.
A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.
from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
I have a 2012 Nexus 7.
Previously the usb socket was damaged and when the charger was plugged in nothing happened.
I replaced the usb socket and for 3 months it's been fine.
This week though, it's not been charging.
When i plug I the charger cable, the tablet recognizes it and indicates it is charging - the tablet though slowly goes down in charge.
I have 50% of battery left.
Any ideas?
1) Running what version of Android?
2) Wall charger or USB port from PC?
3) If wall charger - original?
Fixed it. The connection to the battery wasn't secure.
So i am having this problem, wonder if anyone else is also. I reported it to samsung.
The problem is when using a car charge my phone will say charging like normal. BUT then it will says "powering connected usb device".
It will say this the whole time it is charging.
Its a 5v 2amp charger i am using a micro usb cable with the included usb c adapter.
I use the this same charger for my s7 edge without problems.
Now the kicker here. Once i unplug the note 7 from the charger it will keep to saying "powering connected usb device"
The battery icon will flip between the power out icon and normal battery.
The first time it did i had to reboot the phone so it would stop.
The next time it went away after a few minutes.
I havent try using a usb c cable, but will later today.
Just wondering if anyone else is having this problem. Its probably OS related or have something to do with the adapters.
Just wondering if anyone else has this problem
The included micro-usb-to-usbc adapter seems to inhibit the charging speed. I used the adapter with an official Samsung Micro USB cable that came with my Note 5 and plugged it into a Samsung fast charger and the charging takes forever... Maybe you're experiencing a similar symptom?

Its possible. Today i drove for about 20mins and i didnt have this problem. It charged but only went up 3% more. I should of gotten at lest 5-6% with that charger (amount i would of gotten with my s7 edge, same charger in cable)
I will do a test today with the usb c cbale plug right into the usb adapter. I only have the one for the time being
Well the problem is still here.
My wife gotnher phone and the same thing.
She needed to charger her phone.
Plug it up and it says chaning connected usb device. Just stays on the screen for a while then goes away.
Now we got out the car and turn the car off.
Then phone lit up and says powering conntect usb device. Then my rasio started to boot up and ended up in a boot loop as long as the phone was connected.
So thephone was trying to power my car through the usb charger.
This is something samsung should fix asap. There should be an option to turn this off.
Ill have another chat with samsung
