[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.

Do I need a new USB cable or is there an issue with my phone?

I just got the Galaxy S 4 the other day. It didn't come with a USB cable so I used an old HTC micro-USB cable. Even though the cable worked with my HTC phone, it doesn't exactly work with my Galaxy S 4. I have to move the cable in a certain way to get it to charge or connect, otherwise it doesn't work.
I was able to charge my phone using a micro-USB charger for a bluetooth device (trickle charge, took 12 hours to charge), but obviously this isn't ideal. So is there something wrong with my phone, or just my cable? And what type of micro-USB cable should I get that might work?

It doesnt come with usb ??
Charger works as USB too.
Htc cable doesnt work on samsung phone. Motorola does.

It isn't your usb cable. You need a charge that output 2A at 5V to charge the S4 at decent speed. Computer's USB or typical 5V USB chargers will not do.

Just FYI when I use an older usb cable other than the samsung one, my charging time increases. So using the right USB cable matters. I use an app called Galaxy Charging Current Lite to determine my charging amp with other cables and other wall and car chargers. Very useful app. When using the samsung usb cable with the wall adapter I get 1900 and I can see the battery percentage go up faster. Using an older usb cable with the samsung wall adapter I get about 460 and battery percent goes up slowly. Try the app out and see what you get.

First thing I'd be doing is complain to T-mobile or Samsung. Both GS4s I've received (one on launch, one from insurance) came with the USB cable and charger ready to go.
Next, you need 2A @ 5V, but ya need the right power brick to supply that.
and most likely using older/newer/non-Sammy cables and charge time increasing is because the cables use a smaller gauge wire (like 28 or 30 AWG IIRC) rather than say, 24 or 20 AWG (keep in mind that the smaller the number the bigger the conductor, and larger numbers have smaller conductors). Even with the right power brick, the USB cord still matters; I remember on my Nexus 7 that unless you used its cable charging was either sluggish or non-existant. (FYI the Nexus 7 cable should work with the GS4, I use it for file transfers o my computer and when I did all my rooting.)
also I personally use the battery monitor widget on my Nexus 7 to monitor voltage/current input/output. I may consider putting it on my GS4.

P605 Charging Issues - Voltage?

I've had some trouble charging my new tablet.
When I first received the tablet, I plugged it in to the supplied cable and allowed it to charge to 100%.
I used it for a day to run the battery down.
I then left it plugged in to the computer with a standard cable for 11 hrs.
It appears that it didnt charge at all.
Now I drove all the way back to my office to test it again with the factory supplied cable and it does appear to be charging slowly but it is totally discharged.
I've experienced intermittent issues with charging. Seems like it prefers but doesnt require the samsung charger/cable. Are the voltages and everything the same?

Yeah, seems like it wont charge on a usb port. Only seems to rocognize the supplied samsumg charger...

Do you see that the battery icon has a red X over it when you have it plugged into the computers USB port. The tablet needs the power that the supplied Samsung charger puts out to charge that big battery.
On page 9 of the users manual it says "Note: You cannot charge the battery using the USB cable and
your PC"
.

so is it just a 2A usb charger?

When it's got the red cross over the battery symbol (when it's plugged into a computer USB or car charger etc) it does still charge, but very slowly. Probably only with the screen off.

It charges with any standard charger. I use non-samsung charger and it charges fine, in fact I have not removed the original charger from the box.
As with USB it does charge but really slowly, while it shows not charging.

I believe that a standard USB is 1A and the note 2014 is 2A. Can anyone confirm?

Yes, this is correct, my standard Galaxy S4 is 1A, however a computer may put out even less than this.

No. Standard USB 2 port supplies 0.5A. USB 3 port will supply like 1.5A or less. As for USB 2, you may install (if motherboard supports it) ASUS Ai Charger so that it supplies 1A.
I have gigabyte mb and it has its own driver to over supply usb 2 current. With that I have about %6/hour charging rate if screen is off. Using Samsung own charge, I got about %24/hour.
PS: Look like my desk usb 2 port supplies .5A only (%6x4=%24).

I think you're right. I'm using a 2.1A CostCo Charger and it seems to be charging the 2014 P-605 perfectly.

Not to be rude, but what you wrote here makes no sense to me .

i got the charging issue also, with original charger 2A, original USB cable
checking with galaxy current, value at 900mA

my tablet charges perfectly with original charger and cable but using every standard usb charger (2A and 700mA) it charges but the "connection" is unstable: it's like usb is connecting and disconnecting repeatedly.
I've checked every connection, using the same charger and cable with another phone the connection is stable.
Anyone with the same issue?

[Q] New Note 8 not charging via PC USB

Hi Guys,
I'm just wondering if my unit is defective or it's really the case for Galaxy Note 8's. My tablet charges just fine when using the wall charger, but when I connect it to my PC, it won't charge at all. I've tried different cables that I use for my phone and other gadgets, but none of them will work.
Is there a way for me to make it charge via USB?

Mine also says not charging when its plugged to the PC, its because the USB ports supposedly don't give enought current to charge the tablet, but i once left it connected overnight while transfering my MP3 collection and in the morning the tablet was 100% charged, so i think even if it says is not charging, it charges but ultra slow, even slower than a cell phone.

USB ports on a PC does not put out enough voltage to charge the tab. Like said above, if it does, it will take forever. Look on the back of your wall charger. It should say 10v. USB ports typically put out only 5v. If you look on the back of a phone charger, it should be 5v.

It's not the volts, it's the amps. Your charger provides 2A. A typical USB port provides 0.5A. But in any case, you'll not be able to charge this device from a computer USB port. It's not a fault in the device.

That explains it then. Thanks guys :laugh:

Hmmm... I alway charge my note 8.0 thru my pc usb.
It charges on my pc and lap top.
If you want to be sure just let is sit for an hour and see if the % went up.
Doesnt charge fast but charges in an evening from 60 to 100%

Perhaps it doesn't charge while the screen is on, because the power drain exceeds the charge rate? There would be no way to see it change to "charging" because the screen must be off for that to happen... Just some speculation

I have a HP Envy M6 laptop that I use to charge my Note 8. It only charges on the port closest to the battery. The only USB 2.0 port out of 3 other USB 3.0 ports which is odd because they say USB 3.0 ports give out more power.
I have tried charging it with another HP laptop that has the same USB setup but it doesnt charge in any one of the ports, 2.0 or 3.0.
I guess it just depends on the PC you're charging it with.

Can charge.
hi,
We can charge note 8, if the note is switched off and connected to a PCvia USB

Normally Note 8.0 can not charge with pc usb port or car usb port because AC current of them too low only 0.5A (minimum AC current of charging require should be 1A)
Samsung Tablet stock charger is 2.1A (Note 8.0 device allows 1.8A)

Replacement usb charging cable?

Bought a pre-owned N7 today but it's missing the official usb charging cable. Don't suppose there's a cheap solution? The Asus shop only sells the cable and adapter together and it's rather pricey here in Ireland.
I know there are cheap non official cables you can get but I'm not sure whether they will just cause more problems.
Help! Thank you!

Don't you have any micro USB cables lying around? Any of them should work perfectly.

Ah OK thank you. I just remember the 2012 being a bit fussy about what cable it would charge with.

i am going to tell you right now that that suggestion is not good. A while back, i bought 4 OEM LG cables to charge my devices, including my nexus. The cables charge all of my devices other than the Nexus. below this is a link that i posted on amazon to some cables that i have indeed bought and can confirm work with no issues with the nexus 2013 revision.

best of luck

All cables are NOT the same.
From one to the other you can go from .48 amps to 1.1 amps depending. I've seen some output zero on one devise and .44 on another. Get yourself a little monitor to test those cables. Also you might want to get a dumb cable that only charges vs. a smart cable that charges and syncs.

You do not need any special device to test the cables as you suggest. There are two apps I use to test the current flow on my nexus to determine which Micro USB Cables charge it the fastest. The apps are Current Widget and Battery Monitor. Don't need both but both can be used for the purpose of seeing how fast your phone is being charged.
I have many cables I have tried and found that OEM cables do work best for charging, for after market cables I own, the mono price thin Micro USB cables work the best on my nexus 7. I also have amazon basics USB cables but those do not charge well enough. I have a nexus 7 and a moto x currently, so when I can I use the moto x OEM cable with my nexus 7 and any cable with the moto x (the moto x has some kind of optimized charging ability and I have found it charges well enough regardless of cable, but the nexus 7 needs the right cable to charge at a good rate)

Thanks for all the replies....I knew I was asking a valid question. One day my N7 2012 just stopped charging with the supplied ASUS cable. Luckily I had a Samsung travel adapter lying around which it didn't seem to mind! Thanks for the Amazon links but unfortunately I'm not in the States (Ireland).

My Asus cable went bad on me within the first 2 weeks of me buying my tablet (new). I used an old HTC cable with the Asus wall charger for a while, then went with a Qi wireless charger. Much better than factory, now. That's my suggestion to you as well, just go with a Qi charger and be done with wires!

Just get a few micro-usb cables on eBay...

Have you guys found any cables that work with the OEM charger? I broke my original cable, and it seems that all my other cables have too much plastic shielding around the USB port to go into the slot. I have ordered a Monoprice cable and I was wondering if anyone has used this with the OEM charger

I have not had any problems with charging using my various mixed brands of micro usb cables. I have a dedicated 5 port usb charger capable of outputting a max of 2 amps per port and all seems fine. The only problem I've run into is one of my portable chargers seems to not like the N7.

Every single ASUS charger cable I have owned has failed more than once..
They are made cheaply but they charge a fortune for them..
You can find a cheap, but higher grade cable if you look in Amazon or eBay..
Just check what is the maximum Amps it can take..
I go through cords every day.. The ASUS cables failed the fastest..
