[Q] Can't charge with other microUSB cables?

Hey All
Just got my VZW Galaxy Nexus and am loving it. When I first connected the phone to the computer, I used my old HTC Incredible microUSB cable to connect. I realized this was silly, as I hadn't installed the drivers yet. So I pulled the cable and installed the drivers. Upon reconnecting, I couldn't get anything to register. No charging, no data... I tried uninstalling the drivers, restarting both the computer and the phone and still nothing. The phone would no longer register that it was even being plugged in. I grabbed the cable it came with and it worked fine. That is the only cable that will actually charge the phone. I can plug it into any USB charger, and as long as i use that cable, the phone will charge. Additionally, it is the only cable that I can use to connect the phone to the computer. I tried other old cables, but none work. All chargers and computers work with that nexus cable, but none of the other cables work. Any thoughts on this? Is this an amperage issue through the cable? Why would data connection no longer work and why did it work the first time?
Thanks for your thoughts!

I've had a similar experience, tried the charger from my droid OG, and it didn't work. Plugged in the old droid, still charges, new cable charges fine though. Weird, huh?

yea i tried to charge it with my usb cable in my car that i've used for all my htc phones but it didn't charge

Using a charger from a galaxy S here without any problems. Haven't tried connecting to a PC though.

Having the exact same issues and getting worried...This morning I plugged in and it said charging. Now, even using samsung plug it doesn't say "Charging". The cord appears to be charging but the OS doesn't say so.

At home I use the AC charger that came with my Nokia N97 mini: no probs. At work I charge with a cheap brandless USB cable plugged into my laptop: no probs.

Ok, I guess I'm going hunting for a working cable. My friends Orig. Droid cable works so I might trade out with him...might not mean anything, but the cables that work have slits cut in the forward facing part of the microUSB, and the ones that will not charge do not. This may be an issue of my available sample, but perhaps there is something else going on here? Just jabbing in the dark here...

I'm now using my Nokia CA-101D MicroUSB cable (with an extender, because the single cable is long only 10 cm) with my PC and it works perfectly.
The original Samsung cable that come in the box is always into che AC USB adapter, to recharge de GNEX on night.

Interesting. I had an old Motorola Charger (one piece unit, not separate charger and USB cable) that would't charge my Galaxy Nexus. However, I have used a Kindle 3G charger and Blackberry charger that have both charged it without a problem. I figured that for chargers that separate the cable and AC adapater it would be the problem with the adapter and not the actual cable but I could be wrong.
I did read on another forum that newer devices with bigger screens like the Nexus can't take a charge from older chargers because of the makeup and power use of the newer devices.

I was thinking some companies switch the pin-outs of their cables/ports so you can't buy a normal cable and have it work....I could be totally off base though.

Mine works on 4 different cables on two different boxes. Haven't even opened the one that came with it yet.

You guys not working are you with a Verizon Galaxy Nexus?

Oddly enough, I've used my old Incredible cable (perhaps it was my Thunderbolt one, though) with no problems. I'm on the Verizon Nexus if that makes a difference.

Using OG Droid usb for data transfer and an old LG usb to charge overnite. No problems. I haven't even unpacked the nexus one yet.

there are no special cables.. they all have the same pin out, the only reason why some work and others dont in cars, is based on the actual charger itself.
if you have a cig charger with a usb female port, you have to rig it to work, the middle 2 pins are shorted out with foil/tape and it'll work
if you have a full cigarette with cable unit, nothing you can do about those, they either work or not (mid 2 are shorted on build/factory)
i use any old 1A-1.5A usb cig charger, then short the 2 middle pins using ANY cable (i am using bb cable) and it works fine.. even did it with several cables and chargers for friends so we didnt have to spend no stinkin $10-15 bucks for a charger
all this bs is really a way to control the market of accessories, making you buy new ones that are shorted out sine the old ones arent and wont charge

I went on eBay and bought a spare set of 5V 1A home and car plugs, those seem to work great.

Mines charges just fine using Nexus S wall charger + USB. Kinda disappointed with the Galaxy Nexus USB... its shorter than the previous USBs that Samsung offers.

Samsung phones don't play nice with other chargers. Using non Sammy chargers is ill advised. I run a warranty center for one of the big 4 cell phone companies ... trust me. Only use Samsung chargers.

I got a htc incredible cable that depending on my rom either only does charging or I can transfer pics etc. odd ball phone. it wont do a odin without failing. for stuff like that I think all cables have an extra pin for their phone model used for firmware.

[Q] 120v/USB wall combo outlet charges everything but the galaxy S4

Today I picked up and installed two combo 120v/USB wall outlets so I can get rid of all the wall warts I currently have. The USB ports charge everything (tablet, HTC phone, Bluetooth) but the two galaxy S4's I have. Has anyone used one of the outlets before? Any ideas on why they will not charge the S4's?
The Specs for the USB side of the outlet is.
Switching Frequency Typical 140 kHz
Output Voltage Nominal 5V (+/- 10%)
Protection Current Limiting and Thermal Shutdown Protection
Output Current Constant Current Maximum 2.1A
The outlet is a Commercial Spec Grade Combination USB Charger made by Cooper Industries
Part number is TR7745 if anyone wants to look it up for any reason.
Thank you in advance for your help.

change usb cables
Try changing to a different USB cable. It's weird how often this is the problem.

What does it do when you plug it in? Does it do anything at all? Does it even act like it's connected? Does it TRY and charge but just can't keep up? I have ones by Leviton that work fine with my S4 and my fiancees iPhone/iPad.
EDIT: I just noticed if you look at the reviews on Amazon HERE it seems multiple people have had problems with the S4 and this model. One thing I noticed with most that I looked at before buying mine was that the listed current was shared between the ports, whereas the Leviton version has one port that's 2.1 amps and one that's 1 amp independent of each other. This one might be 2.1 amps shared, so anything else plugged in might not work out.

I'm having the same problem. It's listed as "dual 2.1A". The first second I plug it in it flashes the charging indicator, then it goes off. No charging happening whatsoever.

Did you ever have any luck with the S4 problem? Does it make a difference which side you plug the USB cable into?

Try using a different usb cable from phone to charger,
be sure both ends have a snug fit and it should work.
I have one which is similar to yours.
Since it puts out 2.1ma just like the stock S4 wall charger
it should charge just as fast.
Good luck!

Unfortunately no. I didn't mention before that I'm an EE, however, none of the troubleshooting steps I could think of had any effect. :crying:

Can use A Cooper USB Electric Outlet with S3 and S4
I saw this thread while trying to solve this very issue. I have the Cooper USB outlet and installed it thinking it would charge my phone and my wifes. It would charge her S3, but not my S3. She has the LTE version (SGH-I747) and I have the HSPA version (GT-I9300). Well I thought it would not charge my S3. After playing with it for a few minutes, I could get the charge light on the outlet to blink. No charging was happening as the charge light on the outlet would just blink and then stay off. On my wifes S3 I could plug it in it would start charging instantly.
After playing with my S3 and the cord (The same cord used for my wifes S3 as I had already tried numerous cords) I found I could slowly insert the micro usb end into my S3 and it would start charging. It was tricky, but after 30 minutes of wasted time, I got it to charge. I would have to ever so slowly plug it in, either at a sideways angle or at a slightly elevated angle. This was regardless of the usb cord used.
However my S3 died and I got an S4. Naturally my S4 would not charge just by plugging it in, but I tried the "slow insert" method, on both the micro USB side and the outlet side and both worked.
I am thinking there is some kind of tolerance issue surrounding the electrical connections. Sliding the USB connector in slowly at the outlet side, I beleive, would ground the connection first and then allow for charging, but this is where my knowledge of electricity starts to bad. That said it is possible to use the charge, but it is not plug and play.

I just picked up a couple of these for the kitchen to alleviate the eyesore of the wall warts and I can also confirm it charges everything I have thrown at it except my S4 (jfltezvw) =( I quickly found this post after googling it. I am currently doing some work on the phone now but I will attempt the super technical "plug it in slowly" later and see if it works =)
Has anyone had any luck with other brands? I find this REALLY odd.

just installed this same outlet, and sure enough it charges everything except the S4..."slow insert" doesn't seem to work...does anybody know of any other solutions besides not using it?

wall charger option
I also have one of these outlet/usb from cooper that will not work with my s4.
Has anyone tried to use a DUAL POWER micro USB cord (like the ones that comes with the portable hard drives) to see if that would do the trick?
unfortunately, I do not have one of these cables, or I would try it myself.
Here's what I am thinking is happening...
The S4 is equipped with a smart charger that can trickle charge after a complete charge cycle.
When first connected, the s4 starts a trickle charge while it tests the battery for the charge cycle.
The cooper is equipped with a current limiter that shares power between the two outlets.
The cooper unit sees the trickle charge, and switches to a lower current setting for the slot with the s4 plugged in. reserving current for the empty outlet.
The s4 then tries to engage a fast charge, but cant due to the lack of current, and shuts down the charge circuit.
If a dual usb cord to micro usb cable was used, both outlets would be tied to the s4, and full power would be available to the s4 at all times.
Of course, without a cable myself, this is almost all conjecture on my part, and I could be just blowing smoke up my own arse, huh?
LoVoltage
EDIT: Of course, remember that the cable you use has to have the D+ jumper to signify the 2.1 amp availability. If you don't, the cable won't work. (Most dual port usb cables have this jumper already. so does the OEM samsung cable)

Just installed one of these tonight. Specifically the Cooper TR7745/TR8245 15A/125V
I can charge my Note 2 (SGH-I317), Nexus 7 wifi, but not an Samsung Galaxy S4 (SGH-I337). Kinda weird.

Slow charge

Hello xda members, i have been experiencing a problem on my tablet Samsung Galaxy Note 10.1 (2014 Edition) Android version 4.3 since the past month. It does not charge as usual and a red cross pops up on my battery icon indicating slow charge. I don't know if it's the adapter or usb cable which is causing this, but I tried a set of new charger and cable ( Sony brand ) and still I get the red cross.
What do you advise me to do?
Do i install an app from the store to check if my battery is causing this or do I need to try charging it with a new original adapter and usb cable?
Thank you and awaiting your reply.

The red cross only indicates that the tab is not recieving enough power and even if energy is coming in, it is not enough to charge while using. Understanding this, anything can be cause for the current not being enough:
The adapter could be damaged.
The adapter you are using is not the samsung one and thus is giving less Amperes(Out tab needs 2A and most adapters give 850A-1A).
The cable is damaged.
The cable you are using is not prepared to transport 2A.(This happens to me with the chromecast ones)
The microUSB port on the tablet is damaged. An indicator may be the tablet overheating like crazy when charging but this is not probably because when this happens the device, in most cases, takes energy or not.
I personally find that the cable, if you are using samsung's adapter, is most commonly the problem. Using a cheap cable or a damage cable causes this for most of the tabs I have known.
Hope this helps.

Thanks for replying mate, actually I'm using both original samsung adapter and cable which came in the box.. I will be heading to some shops looking for a Samsung cable and see whether it resolves the problem or not.. What is weird is that sometimes it has the red cross and sometimes it doesn't. Yesterday evening it was slow charging and this evening it was normal charging.

It happened to my brother, he changed cables and changed from light socket and he said he had no more problems; he also may have cleaned the usb that goes into the adapter; ol' "blowing nes carthige" style. I would recommend getting a Q-Tip with alcohol and cleaning every metal part you see in your cables, speacially the 4 metal bands inside the male and female usb port from the adapter and the cable(remember to let it dry before pluggin it again).
BTW, it must be a good cable but it is not necessary for it to be a samsung one. If you have a good phone around and can use that cable, it should be fine(I use a motorola defy one which had a 850mA adapter and it works marvelously; "meh" cellphone but the accesories are darn good), just dont use other adapters because of the Amperage difference.
Also, if you are using any kind of extensions, specially usb port extensions, don't. They are a sure culprit of the problem you are experiencing. I dont know why but these cheap electronics really affect the energy passing through; maybe its the cheap copper or bad solder.

Some questions on charging battery issue

Hey guys. Just wanna ask some question.
My note 10.1 2014 P601 is now running stock 5.1.1 un-rooted. Basically everything stock. I know that our Note need its own charger to work properly. But I lost the original charger long ago, and I've been using only the USB I bought separately to charge my tablet by connecting it to PC.
Now, my mother just bought a new phone (Galaxy A7) and when I try to charge my tablet with her charger, sometime it shows X mark (which means insufficient, exactly like when i connect to pc via USB cable) on the battery icon, but sometime it shows the lightning (which is fine) icon. The speed of the charge depends on that sign, if on lightning sign, from 0 to 100% takes about 4h. But if on the X mark sign, 4h will just get around 40%.
I don't really know what happened, but I have to unplug then re-plug again and again to get the lightning sign to come up. I then bought a new charger (from a legit well-known store and they said it's the best quality) and it does the same thing. I haven't got a chance to borrow anyone's original note charger yet as I found no one using this device. And now I start to think it's the problem with my Note more likely than anything. I haven't tried to reinstall the firmware either as I just updated the firmware like few months ago.
I've been using it for about a year btw. Sorry for my English. And looking forward to hear from you all.

The usb jack or its solder contacts may be damaged. Also, if no case is used and the backside of the Note squeezed when holding it in your hands, the cables for usb and display may work themselves slowly out of their pcb connectors. I don't know if the squeeze theory is right, but definitely there are many loose cables...
A charger must be Qualcomm Quickcharge or Apple iPad compatible, 5v 2A. I haven't used a Sammy Charger for a single time,tho they seem just too good to throw away.

Are you sure the Qualcomm Quickcharge would work on this P601? I checked the list before and I didn't see the Note 10.1. Not even the Note 3 which was released together. I afraid that being "not compatible" might fry the device.
If you're using one and not having any problem, can you post the link to the product that you're using and working well?

I forgot about the different SoCs. However, all models charge at 5v/2A and the signaling technique used for Quickcharge seems to be borrowed from that of the Apple iPad, the Exynos based models should be just the same. I plugged my Note into an Apple compatible charger, which was from a time when Android smartphones were charging at 0,9A and Android tablets had proprietory connectors, and it was charging at 2A.

Quick Charge 3.0 and USB C not working

So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.

It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass

Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.

Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).

So how the story ends? We're you able to solve the problem?

I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer

Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-

I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
