Yes the same thing happened to me,,i took the charger back..and got a proper one

just for reference, the Black Berry 9600 chargers are compatible with SGS 9000
i bough one for car use

So are the moto chargers.
My car charger is an old razor v3 mini-usb with a mini-usb adapter.
My wall charger is an old Razor v9m charger.
Never tested a BB charger as i have always charged mine with the moto ones that were already plugged in

yup i also purchased a mini usb to micro usb adapter to use my old Moto chargers with my SGS

The same happened with me while using the stock charger in a train. The capacitive touch buttons and the screen stopped working, but the hardware buttons were working. So I plugged in my laptop and used a USB cable for charging it.

Never heard of this before....
I've not come across a charger that does not work.

The chatger works but the phone doesnt while its plugged in! my back button and menu button still work along with hardware buttons...... Weird... Allready ordered an official replacement

That will be the cable that has issues.
Pity you couldn't have tried another cable.

I am using a nokia car charger, also works fine. Blackberry didn't work for me

Yeah i know the cable causes the issue but does anyone know how? obviously other after market chargers are ok... Phone charges fine too, just cant use it when charging...

i'm using After market chargers too, but i have no problem
my car charger is using a BlackBerry 9500 charger (2A)
an in my PC i use a Motorola sync/charge USB mini + micro USB adapter to make it compatible with SGS 9000
they all work fine
i have not even unpacked my SGS usb cable that came in the box

Is any of this chargers really recognized as charger (charging with more than 500mA)?
You can easily verify this with the app "OSmonitor".
IF you see this: "USB Power: Online and at AC Power: Online" everything is working as it should. But if you see "AC power: Offline" your phone thinks the charger is a pc and it will only charge with 500mA.

The only problem with software informers here though is for those that have the problem and the screen locks up whilst being charged the software is of little use.

This question was not for people having a faulty charger but for the ones claiming that they have a functioning charger!
If the charger is not really recognized as charger it is useless for navigation. As the Galaxy S need more than the 500mA while navigating (with GPS).

yeah, minimum you need a 1A (1000mAh) charger
that's why i prefer the 2A chargers, it gives just enough juice to actually charge the battery, and use GPS+3G+WiFi+Bluetooth
else the car charger will not even be enough to power all those, and it will still consume the battery power.
that's from experience from my HTC phones

I bought a Sharper Image Retractable USB kit that has adapters for most of the USB sockets out there. But the Micro USB that came with the kit fails to work with the SGS, the retractable USB cable is set up like an extension cable which works fine as an extension cable but putting on the adapters dont work.

Charger issue

I haven't seen anyone else complain about this, so it might just be a small defect or isolated incident.
I always charge my phone during the night while I sleep and just recently woke up to find the phone only at ~70%. For some reason the AC adapter seems to be malfunctioning. Since the issue has started, I managed to get it to charge to full one night, but the rest of the time it seems to stop charging. It recognizes it being plugged in initially but then it pops up with the notification saying that the charger has been unplugged. I've tried reconnecting both connectors which will sometimes get it to start charging for 15-30 seconds before it shows as disconnected again.
It works fine via USB connected to a computer so I can only assume it's an issue with the wall adapter. I'm not sure if there's much I can do if it is an issue with the adapter but wanted to see if anyone had any ideas that would be worth trying before I give up on the adapter. Also wondering if anyone else has had this happen.

I don't have that problem. Call and get it replaced. All you news is a USB AC adapter.

Have you checked the socket you are plugging the charger into? Have you tried a different wall socket or socket on the power strip?

Are you using a Motorola brand wall outlet and usb? I was using an aftermarket cable and had this issue. So I got a branded cable and now it's fine

i had same issues
my atrix would only charge also to 70% so i was about to return it. i forgot that it also came with a stand alone battery charger to charge just the battery. charged it and then put it on my atrix and said 100% again. hope this helps..

Yeah get the wall socket and make sure that's not the problem. Also I can't imagine it being the cable I use a 15 foot after market cheapo cable I got off newegg for like 3 bucks and it charges my phone all the way and I don't even use the wall adapter moto gave me I use some random one that's for one of my old phone or my nikon camera I don't remember. Also moto cable is crap it doesn't let me use adb doesn't seem to push enough power to my phone.
But thats just my 2 cents

Transformer stuck with "Connect your Charger", charging slowly

Hello.
I m having a problem with my transformer. Right now it is charging slow as if it was connected to the computer and not the wall plug. Also the message "Connect your Charger" won't go out of the screen, even if it is connected or fully charged. I flashed a custom ROM to see if it fixed something, but I had no luck. The cable works fine to connect the transformer o my PC the only thing wrong is that is is not charging properly and the message won't go off. Do you have any idea of what could be happening? My wall charger is model OB-1LF, which I believe is not the one with the known fault. Any ideas?

the adapter is surely broken.

This will sound nuts but, put your wall charger in a plastic baggie [push out all the air and then seal the bag] and put it in your freezer compartment for say 3hrs. Take it out [still in the bag] and let the charger warm up to room temp.
The charger may now work. It is worth a try. You would be trying to be sure the thermal fuse inside the charger is reset. I brought one back to life that way.

the TF uses pin 7 in the USB connector to signal the charger to use the 15v output. If the charger does not see a gnd on pin7 it will only charge at 5V as ypou are seeing. Are you using an extension usb cable? If no then check the pins on the TF and cable for bent or damaged pins. Also try the freezer as the charger may have gone into safety reset.

Thanks for the answers. I will try the bag and freezer to see if it gets fixed.

I know that this freezer trick works (also with broken hard drives too apparently), but what's the physical reasoning behind it? I swear I've seen a good explanation of it before but I can't remember..

Same problem here... Even had the charger replaced but of no use. It does charge wth a different (do it yourself) charger usig the same cable.Maybe that doesn't have the 5v/12v mode or something...
Going to order a new adapter and hope thatll fix it otherwise I'll send the entire transformer for repair i guess :/

I just got one today (got a good price on Amazon)
it just will not charge, tried all the fixes! not too happy as i went for the asus over the ipad and apparently quite a few people have charging issues with it.
charges very slowly through my laptop
From reading posts on forums is sounds like a few people are having it and Asus should of recalled the charger.
phone call to Asus tomorrow

There is overtemp protection circuit that should reset once the charger cools, but apparently it needs to cool down past room temp. The freezer is cold enough to reset it. I would not buy a new TF charger search for devcakes discussion there several aftermarket chargers that work well

Check the cable. I had the same problem. At first I thought it was because of faulty charger and had it returned and got a new one from Asus, but still had the same issue. Then I returned the cable for a new one, it worked flawlessly.
A plus: Asus gave me new cable which was much longer than the original one.

the cable is fine, used it to charge via my laptop

I had the same issue with my charger. I called up Asus and was able to send it in for repair, after a couple days they mailed me a new charger and cable.

Charging with your laptop does not involve pin 7 and supplies 5V. If pin 7 or that conductor is bad or you use an incorrect USB extension cable, the pin 7 signal will not get to the charger and will not supply the 15V charge voltage for normal charge.

Cheers will send the cable as well to be sure but am pretty confident its the power adapter.
Hopefully i will have an adapter for next week.
I had a brief play on it and i was quite impressed, the stock browser was surprinsignly good and may unistall dolphin.

I tried the freezer trick, but it didn't worked. I ordered another wall charger to see if it works. What's really weird about this is that the Connect your Charger message will not go off the screen. It doesn't matter if it has 100% charge it will still show "Connect your Charger".

In my case my Transformer didn't want to charge at all. The red light never came up while connected, the only way to fix it was to drain my Transformer all the way until shutdown and then plug it in and voila! It started charging again ever dince.
Great tips by the way!
Thanks

Just an update, after ordering a new adapter (with cable) it now works... Appearantly the cable was the problem afterall...
New cable with old charger = ok, new cable with new charger = ok, old cable with new charger = no go, old cable with old charger = no go.
And old cable with 3rd party adapter supplying 12V = ok, heh...
New cable is longer indeed, now I just need to think if I wanna go through the RMA process again for the old cable. But yeah, cable was the issue (out of nowhere btw).

The Pin 7 Connection I referenced earlier is bad. This prevents the charger from outputting 15V.

Yeah, I read your posts about that... couldn't see anything wrong with it on the outside though (with my eye) so unfortunately no clearly bent usb-pins or anything.
Any tips on things I can check? Could easily be on the inside as well of course in which case I can just forget about fixing it. At least it still works with another (non asus) adapter.

Mine was also doing a slow trickle charge. I ended up getting a new charger, but found that the problem was with the cable, not the "wall wart". I can still use my old one with the new cable and works fine as well.

[Q] Nexus 4 charging mode won't stay in AC, drops to USB

phone only started doing this over the last couple months, used to be able to plug in (either charger / cable) and charge in AC mode without supervision.
Nowadays, it takes several plug in attempts to even START in AC mode, but typically it'll drop down to USB (the screen comes on momentarily when the change occurs) at some point in the charging.
Worst case scenario, it'll change rapidly back into AC and out, to the point where I can watch it on happen on the screen. That's rarer though.
It never changes INTO AC and stays there, to be clear. Always a downgrade to USB charging.
Is something wrong physically with the jack on the phone? I've never damaged the phone, dropped in water, etc.
If RMA is what's suggested as my only option - is that a brand new phone or refurbished?

Use another USB charger, its a known problem with the supplied LG charger with the N4. I myself have this problem but am using another charger and its fine.
The USB cable has no problems btw, its the charger itself.

Can you link to your sources on this being a "known problem" ?
I'm pretty sure the same issue persists with my old Samsung charger too - the one supplied with the Galaxy Nexus. So.. that suggest the problem is with the phone, not the charger/cable.

i also have the exact same problem just now.. i'll try using another charger tonight at home..
just now i charged my nx4 using its original charger, in just a couple of minutes, the phone is saying that its being charged using usb.. stupid..

I'm also getting this at the moment, I'm completely stock, not even rooted and this has cropped up only since the 1.8mb Security Patch....
Any fixes?
Will root if I can fix it....

I was/am having this issue as well. I typically charge my phone via car charger (works fine) or wireless, so I can get around this issue easily. Plugging it into the PC and enabling fast charge with franco's kernel works as well.
I tried my N10 charger and it was dropping to USB as well. When I'm at my friend's place and use his generic charger, it works fine.

I used to have this issue but ever since I updated Android to 4.3, my charging works just fine.

Might try a factory reset and see does it make any difference...

do we have any more thoughts on this issue? is it a software bug? is it hardware? which hardware? I am going to experiement with a few different wall chargers and usb cables.

so 3 chargers (Galaxy Nexus' , Nexus 4's, USB 3.0 port on PC) and 3 cables (likewise + cable from monoprice)
SEEM to yield the results, that the problem is the connection between the cable and the phone. The oldest and most used cable has the hardest time establishing and maintaining an AC connection, the newest/lest used one from monoprice has never had a problem, and the LG cable is in the middle.
Is this an issue of wear and tear on both the cable connectors and the phone's port? It's really lame the phone and it's cable are not even a year old and THAT can't stay charging at AC voltages.
Will a replacement phone from Google be a refurbished unit or brand new?

They will send you a new (not refurb) phone and you will have 21 days to send back your old phone. The replacement process is super easy, just call them at +1 855 83NEXUS and tell them your issue. They will walk you through a factory reset and if the problem is not fixed they will replace it.

I've had issues with the microusb port on multiple phones in the past, and have definitely noticed the N4's socket getting looser.
On an old HTC sensation, I had to resolder the port on. Can you reproduce the behavior by applying slight pressure to the plug in various directions?
Does your connection also intermittently drop out when connected to a computer?
A workaround for the time being could be to use a kernel that allows you to force fast charging regardless of the detected charger. But at that rate, it's quite possible you'll lose your usb port altogether sometime in the future..
You could also enable adb over wireless, and check the charger type:
Code:
cat /sys/kernel/debug/msm_otg/chg_type
You should be seeing DCP (has the data pins connected, possibly with some resistance).
Or proprietary if you're using an Apple-compatible charger (has aspecific voltage on the data pins).
If you see SDP, it means it's in "USB" mode.
If it's staying DCP/proprietary but the charge rate is dropping to "USB," it means the phone is throttling down the current because it's detecting the charger can't deliver (voltage dropping below threshold).

with the good cable (monoprice), wiggling has no effect.
with the poorest cable (samsung), wiggling will rapidly change it between AC / USB / nadda
with the LG cable, wiggling, will SOMETIMES have an effect. sometimes it's solid and will only become a flaky connection after it's been charging a while already

[Q] original cable not charging fast enough

I just realized my original cable doesn't charge my phone fast enough and I drain battery while using it. I swapped for a Motorola micro usb, and it works.
I downloaded an app to show mA rate, and with original cable it goes at about 360 or 450 mA. When I use Motorola cable it goes to 1900mA and proceeds to raise battery %.
What can cause this? The plug looked little dusty, I stuck a twist tie in and out (like on bread bad) and tried to clean it, but there's no difference.
Also there's no pin 4 on my cable, the ID pin I think. That seemed to be common for Samsung, so guys, what do you think caused cable to go bad, or am I missing something?
Also I use BlackBerry charger it says 800mA, this will charge it.
Thank you.

Could have just gone bad. Batteries go and all the time. I just had o swap out my sisters amdnmine for new ones because they wouldn't hold a charge for more than 6-7 hours. So its possible you just had a faulty one. Btw the phone is meantnto charge slowly. The faster your battery charges usually means the battery is giving out. But in your case you found out it was the data cable.

Could u tell me which app you used to show mA charge rate.

Its your wall mount. Try plugging the original USB into the moto box. It should charge fine. If not try the obvious (original box to moto USB)
Happened to me on my s3 and my s4. Sucks.. i know..

No pretty sure it's the cable. Used cable on 2A nexus charger, and it only did 300 mA.. I wonder where I can buy a good 4 or 5 foot usb cable for not too much money? The default usb cable length (3ft) is usually too short to reach the outlet for me. =(

I just googled this.. cheap 6ft samsung micro usb.. great prices from local places like walmart and amazon.
Although you might wanna add 2000mah. Lol

300Ma means your USB cable has no Power wire and you are just getting power from Data wires
460Ma is what you would get from a Data USB port
1A is what you get with a good USB cable and Charging Data port
1.2-1.9A is what you get with a good USB cable and Wall/car charger that can provide 2.1A.
good USB cable= 2core for power with 24AWG wire size and 2 Data wires at 28AWG.
Not longer than 6feet
