Hi
I've been using a Nexus 4 for almost a year now and am mostly happy with it. One major problem is that I cannot charge it in my car. When connecting to a car charger and using it as a GPS navigation device as well as audio through bluetooth, the charge drops much faster than when working solely on battery. When the charge drops below 20% it crashes down to under 5% in a few minutes.
I've tried different chargers. A couple of them are rated for up to 2.1A and are good enough for iPads. Belkin, no name Chinese ones, etc. It charges nicely when connected to line chargers, either iPad ones, or the LG that came in the box.
On my last trip abroad driving around it become simply a nightmare. I had to constantly manage the battery turning services on or off, got stuck without GPS one night in a not so nice part of town, asking every time I stopped for lunch for the phone to be charged, etc.
Any recommendation? I can't really return it to Google as it was bought in the US, and I live abroad.
Hi Junior,
If your USB cable has the 4 pins (power and data) your phone may be trying to connect for data transfer. To disable the data transfer connection ensuring that the phone will connect for charging you need to go to Settings -> Storage, at the top-right corner click on the 3 dots then "USB computer connection", finally uncheck both protocols (MTP and PTP) then remove and plug back the USB cable to your Nexus 4.
Well, I had to do this and it worked fine! Good luck! :fingers-crossed:

Hi all, after months of try&error and buying 2 (TWO!) MDAs (Wizard & Charmer) i finally found out WHY sometimes GPRS data flow stops and no incoming calls will be put throught (they land on mailbox):
It's the docking stations! Just let me explain that a little bit more: Both Wizard & Charmer will be delivered without any docking stations, so I bought two different on Ebay + one active holder from Brodit for my car.
After I put Wizard or Charmer in one of the docking station it's necessary to call 2 or 3 times until the call gets through, also in the car (Brodit), and - GPRS data flow, that means even I'm connected (2 GPRS arrows are there), stops after 2 or 3 minutes. I see that with a network monitor called Phatnet (very recommended!)
So now comes the real scurillic thing: If I use the original AC adapter from T-Mobile nothing of the above happens... GPRS data packets flow hours and hours without any breaks, and calls come through.
The docking station definitly loads the devices, but it takes longer. So here's my conclusion: The AC Adapters and the car adapter give to little current for the radio part in the devices - sounds strange, but I have no other ideas.
So now what? Try yourself please, anyone who owns Wizard or Charmer and some other AC adapters than the originals should tell here - it's easy, just put the devices in, surf a little bit for just a couple of minutes and you'll see surfing stops. It's not dependend of the loading status (orange or green led).
I tried different Rom updates, different devices and now it seems that power is the reason, really annoying. Tell us your experience!
Yours B.
Here are the links of the 2 docking stations:

some additional research
Well there's some additional information I researched:
When connecting the device to the original AC adaptor it does NOT switch on the display, when connecting to the cradle it does. So the pinout of the connector must be different and Wizard/Charmer maybe (half way) believes that it has been connected to USB of a PC, but not in a defined state. Remember that my docking station IS NOT connected to a PC, it's only there for power.
Somebody maybe knows the pinout of the delivered USB sync cable and the AC adaptor?

Hello forum,
After researching it for a while, I'm curious if anybody knows if there exists a "Y-cable" to enable charging and syncing at the same time but with 2 separate cables.
I really annoys me to start and stop charging from my PC everytime I connect/disconnect the usb cable. So, what I want to do is to have the wall-charger connected charging the phone in a constant manner, but at the same time to be able to connect to the PC and experiment with whatever I want to to there! Even rebooting the PC can cause the charging to restart, so I want to eliminate this behavior.
Can the normal HTC Y-cable for charging/syncing + headphones be used for this job?
p.s. Enabling the "Do not charge while connected" Power Settings option is not what I want to do. I DO want to charge the phone AND have it connected to the PC.

I don't believe there is a cable for the purpose you want. However, you can use Activesync over bluetooht and accomplish the same thing.
This might work. It provides power for Seidio desktop cradles but in theory it should work without the cradle.

The USB cable will go from the computer to this device and the other cable will go out the other side into your phone.
I do the same thing charge my Tilt and can remove my USB cable or leave it charging if I turn my laptop off.

On note the end of the USB is a male USB port and you need to change it to a mini-male port.
This looks like the one I picked up.

fello posters,
thank you for your responses!!
The bluetooth option is more elegant, but as it is software dependant (BT stacks) I feel almost certain that I'll run into problems.
On the other hand, the Seido option seems to be the one that feels more "natural" and will do the job. I'll look more into that...
Again, thanks for the responses

2 possibilities - if your wire has 2 cables, then one is for charging and one is for data.
the other option is that you have to terminate your relationship with the phone and establish a new one. if this is possible, then likely you will be asked wehther to delete sync files between the two or not. you may choose not to delete.
hope this helps.

This has NOTHING to do with charging.
Yes, check you didnt tick the box "do not charge when connected to a PC" in the power options.
If your battery is sufficiently depleted them the low output from your USB port may be too low to start the charging process.
Attempt the charge from wall charger and then try not to let the battery drain too much.
It is also posible that the power output from your USB port on your PC is defective, Usualy there is a fuse somewhere mounted on the mainbord and looks like a resistor. You can easy check this by using an other PC and connect the phone to that one. You don't need to intsall the ActiveSync on that PC to check. When that one is charging your batery..... Well you know.....
Oh, there is an other posible selution. Turn on your PC Joking
Are you plugging your phone into an external usb hub or directly into a usb port on the back of your computer?
I recently upgraded from an old tmo Wing and it would charge just fine off a port on my external usb hub. When I plugged my HD2 into the same port, it would not charge. If I connect my HD2 directly into the back of my computer, it charges just fine.
I'll be looking for differrent hub that provides more power and will allow for better charging.
if you POWER OFF the phone and it dose charge (orange led should appear near earpiece)
then your pc's usb and your usb cable are fine.
to fix,
go to 'SETTINGS'
and then at the bottom tap on 'ABOUT PHONE'
then tap on BATTERY'
then 'un-tick' the box that says "When the phone is on, do not charge the battery when connected to a PC"
USB Debugging mode might be on. I rooted my phone and forgot to uncheck that box and once I did, it started charging again.
How do I Stop it charging from the computer on Gingerbread Hyperdroid
Does anyone very kindly know how to stop my phone charging when it is connected to the computer with the Gingerbread Hyperdroid. Thank you.
Cgarging inducator but percentage stuck
My phone shows charging when connected to pc but the percentage doesnt move
Anyone having issues with it? I have to fiddle with mine so it can charge or connect with PC. I am debating on living with it or getting a replacement unit

Mines been fine, I haven't had charging issues or data connection issues. I've used several different cables too.
Yes and no.
Charges fine always. But, wiggle it the wrong way and it disconnects from the PC sometimes. But, again, it always still charges.
Hey guys. I seem to be having a problem with my Android HD2. It seems that the phone recognizes certain chargers as USB. The phone allows the option to enable USB Mass Storage and turns on debugging mode.
Normally, this wouldn't be a problem since the phone still charges fine, except for the fact that it limits the incoming current to 280mA. The main charger for my HD2 is a powermat which puts out 1A but when the phone is dropped onto the mat it recognizes it as USB and limits the charging current to 280mA so it charges rather slowly. All the powermat receiver door is connected by is 2 pins. The little 3 pin interface that is underneath the battery door is where it interfaces at via thw two outer pins one for + and one for -.
I thought I had seen this issue on XDA before but for the life of me I can't find the article. I thought I remembered someone saying that you had to short something with a resistor to stop the phone from thinking the charger is USB. Does anyone know of this problem?
I have the same issue and looking for any answers. Using Android 2.3.2 on HD2.

I've had this issue with apple chargers. I am guessing here but I think it is because the iphone chargers send some sort of authentication data to the phone as a measure against unauthorized chargers. See this link for more info
http://www.ladyada.net/make/mintyboost/icharge.html
makes total sense i have heard of that its sort of a self protection
Yes, the new batch of apple chargers have some of the USB pins connected together to indicate that the device may draw more than 400mA from the charger.
It prevents my eBook from charging completely!
The only real way to fix it would be to butcher a USB cable to only connect the 2 power lines.
there are a few threads that talk about how to make some in car chargers NOT get recognised as a car kit, and that uses the same technique mentioned above, , ,namely shorting some of the pins. I assume the same principle will work here. You just need to find out which pins it is.
