[Q] Charging issue!

I'm on a road trip now and every time I connect the phone to a charger it switches it self off.
I have tried different cables and chargers. This also happens if I connect it to my Mac.
Is anyone else seeing this?
Thank you

Funny you should post this, today is the first day at work with my DVP and I tried to use a USB cable connected to my pc that charges my HD2 and SE MW600 headset, connected it to the Dell and it turned off just like you say. Probably not enough voltage/amps, I borrowed a BlackBerry charger and that works fine.

I noted this in my "Nit-picky" stuff post. Needs a 1Amp charger.

Same here.
The only charger that worked is the one that came with the DVP.

I tried the 1A iP4 charger, 750 mA of the Kindle, a third party dual 1A (each) charger, 1A car charger, 2.5A iPad charger and finally my computer.
None of these works, but if it has like 50% charge then it charges with any of the above...

It wouldn't even charge from your computer below 50%??

No...thats not true....But I have seen several different combinations work.
I have the Nexus 1, one of the Jawbone headsets, the HD2, HD7, DVP, and have access to the Focus and LG devices. All of these use the same type of cable.
The HDx cables, the Focus cable, and the Jawbones cables all work with sync and Charging. The LG cable does not...only works for the LG. Some of the older BB cables will only provide a sync or a charge...but not both.
The different USB charging adapters have different results also.
The DELL and HD7 adapter will work. They will work plugged into a wall or a power strip. The jawbone and HD2 usb adapter will not work plugged into a power strip at home, but, both of them will work plugged directly into a wall.
All the cables I have will work when plugged into a laptop, EXCEPT the LG. Apparently the LG cable I have access to only works with an LG.
Now to be honest, the HD7 shows no such reluctance to charge with any combination. The DVP does. My DVP does NOT require DELL only parts, but it is picky about what it will play with.
-My overnight charger is connected directly to the wall. It is a jawbone wired charger, no adapters or usb. All phones connect and charge ok with this.
-My Work office charger is a HD2 usb adapter with the HD2 charger cable.( which is strange because this one will not work at home plugged into a power strip.)
-My HOme office currently uses the Dell adapter plugged into a power strip with a generic sync cable. I say generic because I don't recall where it comes from...all I know its not the DVP or the HD7, because both of those cables are still wrapped up in the box they came with.
-My car charger is an ATT dual USB charger. It has last years model adapter, plus a USB connection. All my phones and head sets charge off of this combination quite nicely. I also have a Tmobile care charger but have not tested it yet.
There is definitely something different about the DVP and charging. I'm hoping Nicolas Cage will play the lead when this conspiracy is made into a movie.

the DVP will only charge with a 1A+ charger. the ones that come with BT headsets don't feed it enough to charge. USB cable plugged into a laptop USB port is hit or miss. The USB port in my car is 1.5A, charges the DVP really quick. I haven't found the make of the cable an issue, the DVP charges with any I've come across so far, HTC, BB, the cheap extendable cable from an airport, etc. it is picky about amps.

The cable is not the problem. I didn't mean that when I plug different cables it does not charge.
I have a charger hub which I connected many phones to it, HD2, palm pre, nexus one and few more and all of them charge from it. When I connect the DVP it shows its charging but in the morning the phone is dead, no charge at all.
BTW, it does charge from my laptop and desktop.

I charge my phone overnight on my PC and never had this issue

I can't get mine to charge now at ALL..
Apparently it drained and shut off in my pocket. Went to charge like I normally do.. and NOTHING..
I noticed a weird behavior yesterday when charging it would jump from charging to not charging to charging. While sitting on my table. NO MOVEMENT to the cord or anything.
Tried Dell charger, tried aftermarket one (that I have been using for 2 months), and PC USB no response from the phone at all. Even tried to swap to a battery I know was low but not dead. Still no response from the phone.
The connection looks good.. but I am thinking maybe I am having a problem with the connector in the phone ?

Took my sons battery out (He also has a DVP) and booted my phone. Plugged it in and it started to charge. Then hot swapped batteries while it was plugged in.. let the battery charge up to 25% and now it charges fine again..
FUNNY it won't boot or charge while plugged in with a dead battery.. but will stay on if booted up and you remove the battery in it..

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

Charging using USB

Hello
as we know, we cannot charge our Transformer using USB.
Thats a pitty as I bought a Solat Charger (expensive one) which can charge USB-Devices.
Now does anyone know how we can fix this? I thought about buying a second cable and changing some connectors? Power is power, it has to work somehow...
any ideas?
thanks

You've got to somehow mod it to give us 15v, buy a usb 3.0 female and change some pin layouts.

It depends how fast you want to charge. I plugged the ASUS cable into an apple charger last night. I then connected it to the tablet and shut the tablet down. When I started charging the tablet was at 72%, when I got up 7.5 hours later, it was up to 93%. So it wouldn't be enough to charge it from nearly empty, but it might be enough to top up the charge after using the tab for a couple of hours. This is with the ASUS cable and no modification to the charger at all.

According to the Tip sheet that came with my TF, USB on a computer can charge it, but only when the TF is in sleep mode (screen off) or powered off.
Have you tried the solat charger to see if it does indeed charge the TF when the screen is off?

Most solat chargers have a 12v plug to power car cigarette jack devices. Connect this to a female usb plug and you can charge your tranformer and dock.

Search for the Charging thread started by Devcake. There is an extensive discussion on the charging requirements of the TF and charging options. Also the pinout and function for the connector. It is NOT true USB 3.0. It just happens to use that connector and some of the conductors.

Impossible to charge sg2 in car

Hi all, just came 3 days ago from an htc hd2, and so far I am more than happy with it.
I have only one complaint and maybe you guys will help me sharing your experience : I can't charge this phone in my car while using gps.
It seems that the power adapter is not powerful enough to charge the phone screen on.
The car charger has a 5v 1000ma output, more than the regular wall charger provided by Samsung and it was working well before with my HD2 so I have no clue about this problem.
Did you experience that issue too, else can you share what car charger do you use?

try to buy new standard car charger with micro plug.. 13 eur and you will be saved..

Charger doesn't matter unless the phone is dropping into USB charging mode - phone limits to around 600-650 mA by default.
Custom kernels can bump this limit up for I9100 users. I777 users are screwed - we've got a crippled charger chip.

I had the same problem, I used the samsung one, useless, so I used my iPad charger, which is 2A, and charges the iPad quick, still useless. We drove from Bathurst NSW, down to Melbourne, about 10 hour drive, plugged in all the way using GPS, and about an hour from home, the connect to charger warning came on!! So once I stopped GPS, it started taking charge. Looks like when the phone is in use, it draws more then it takes charge, plus I read somewhere on here the phone is limited on the charge it takes, so using the 2A does nothing different then the stock 500mA charger.

I always had this problem with my Nexus One, although they are different phones, the problem is the same, uses more power then it can recharge in USB mode.
After trying 3 or 4 different charges I remember that I found one ultra-cheap 'made in taiwan' from a street seller that worked very well.... so it's kind of a lucky shot!
good luck!

Im using a genuine Samsung SGS2 charger and I can charge and run Sygic just fine. I started my journey with 80% and 40mins later I was up to 91% when I stopped and got out. (not in aeroplane mode..)

Very interesting feedbacks... So that confirm that is clearly not a matter of output amperage power.
It is now the same problem on the galaxy tab 10.1, for quickly charge this tab you need the Samsung compatible usb adapter.
It can be likely with a tab bringing a proprietary plug, but I didn't thought it will be the same with a Samsung phone bringing a regular micro usb plug. Quite frustrating and disappointing!
I will search around a micro plug car charger as suggested by redzion, but actually I don't clearly see the difference with my usb charger + a micro usb cable.

Double post, sorry.

If I use the usb cable from my cd player I have the same problem but if I use the official Samsung car charger Ithe only problem I have is the phone getting stupid hot

Oh Samsung, when you will understand?!

Samsung DOES follow the USB charging standard - it goes to its highest current setting when a charger that follows the standard is connected.
Note that iPad/iPhone chargers do NOT follow the standard - Samsungs will treat these as USB hosts and limit to 450 mA instead of 600-650.
Modified kernels can increase both of these values on I9100s.
The only thing Samsung really did **** up is counting screen/CPU current usage against the charge current limits - that's just stupid.

So the charger has smarts. On the i9000 factory chargers, the data pins were bridged. Bridging these pins manually on a USB cable when connecting to a USB source (such as a PC) enabled full current charging. You can see this in Settings -> About; it will say either USB or AC charging.
Do you think this is the case with the i9100?
I don't condone testing this theory on your i9100. Increasing the max current via custom ROM may be a safer solution.

I had the same problem. Two things fixed it for me:
1) I bought this charger: Sony Ericsson AN300 Micro USB 10€
2) I am using a custom kernel now

Any charger that is rated at 1000mA or more (per port) will do just fine. The problem is the cable - you need a quality microUSB cable, or it won't provide all the juice you need. I had the same issue, and I swapped three chargers until I found the real culprit.
Try with the charger you have now and the mUSB cable that was in the phone box - it should work well with that one.

I just press the power button to turn the screen off. when i need the sat nav i press the power and it still tracks you so there is no delay. With the screen off it does charge.

same problem

You are right, but even if it is better than nothing the charging time is still a big problem.
Yesterday I drove for at least 40mn phone off. Arrived to destination, I turn the device on: it charged only from 0 to 5%
I would like to test the mariusi theory concerning the Samsung micro usb cable, unfortunately on my SgsII box I just have a wall charger, no a microusb-usb cable.

Is there a way to know before buying if the charger respect this charging standard?
I have some cheap usb chargers here and no one is a fast as the one provided by Samsung.

Maybe for safety purpose? Gps phones can become very hot behind the car glass.

Samsung are trying to "encourage" you to buy only their official accessories. To do this they've wired something differently in their chargers and cables. This "problem" exists on the Galaxy Tab too and can be solved with this adapter...

It's cheap and turns a trickle charge into a full charge. I don't know the specifics of what they've done, but their USB charging just isn't the same as most others manufacturers.

Great find.

Pretty sure it just bridges the data pins.

[Q] Charging on AC but shows USB

Initially my phone started to charge slow since a week with the original charger and cable came with N4 in the box. I googled and got to check in the battery settings as if it shows AC or USB. Its showing USB and charging quite slow. I flashed yesterday factory image after deleting everything but still it shows as USB.
One more thing, when i connect the charger it shows AC and after a few seconds it says USB and sticks to it.
After connecting the charger it acts as the charger is powered on and off 3-4 times whereas i dont turn the power off/on.
Any help.

Happens to me as well. I even got a new USB cable from Flipkart and tried with other chargers. Same thing happens. I googled enough for this and find no feasible solutions.

It seems to be a hardware issue. but the weird things is it initially recognizes as AC but then after few seconds change to USB.
Further, after pinning the cable, phone reacts as the power is on-off-on-off 3-4 times.
Please help.

It might be a defective cable. I had the same thing happen to me (oem cable and charger), but changing the cable solved it for me. Pretty poor build quality if you ask me

i was using the original USB cable that came with the phone and experienced the same issues. after changing the USB cable it is fixed for me.

i can confirm that it is the cable. just go buy a new one but have in mind that you need a quality cable. the reason is that the usb 2 standard outputs about 1 amp, so most cable is designed with that in mind. the nexus 4 charger output is 1.2 amp so if the charger cannot output 1.2 amp it outputs lower amp thus the connection with the charger is recognized as usb. if you go and buy a quality cable then you will have no problems. i just use the cable of my old phone (optimus black ) and it works like a charm. another cable that i have make the usb thingy.
the lg cable of nexus 4 and all the new lg's is ****. it break down very easily. a friend of mine bought an lg g pad 8.3 and the cable died the 4 time that he used it!!!
P.S. when i say quality cable i don't mean a 30 euroes or dollars cable. i mean a cable by a known brand and not an ebay 1 euro cable. that didn't worked for me. if i knew a brand of cable that worked i would but i use an old lg cable
hope i helped

This happens to me as well but I don't think it is the cable. When mine started charging slowly & on USB with the official one I bought one that was made by Amazon which was fine for a while but then it changed to USB charging

If you have a custom kernel that supports forcing AC charging, give that a try. I think the latest Hells Core/Doctor kernels offer that feature. Unless this feature is on, my phone thinks my car charger is a USB charger. It might be, I'm not sure, but I know that the kernel has a feature to override this recognition and extract the full average from the adapter (in my case, 1A).

I bought the nexus charger off of Google.com and now it always shows charging (AC) and it charge at a good speed
