I have travelled to devon on Saturday and used Google maps navigation which is simply superb as u could see the traffic jams in advance (believe me there were plenty of them) I had my phone charger charging my desire but the battery drained still any idea why surely the charger should charge it or keep the power at the same level ?

Anyone surely someone must know why the car charger hasn't enough power to charge the phone when running navigation and the normal phone functions

I have no solution but I have the same problem. Quite frustrating.
You need a charger that outputs at least 1000mA. Most in-car chargers only output 500mA, and so the phone will discharge quicker than the charger can charge it.

Any suggestions which are the best chargers ? Does anyone know what the new HTC dock will incorporate ?

Get a cheap USB cable extender, cut it in half and short the middle 2 pins. Don't remember what colours they are. Look on Wikipedia.
I had same problem. Not anymore. Charges properly when I plug in through the custom cable.
This is a common problem.
It bugged me sufficiently that I investigated it in detail.
The Desire, and presumably some (all?) other HTC phones, employ relatively complex charging circuitry.
When you plug a USB cable into the phone, the phone does at least two different checks to determine what type of power source you have just connected.
If you have plugged in a mains powered official HTC charger, which has a rated output of 1A, then the phone knows that it is safe to draw a maximum of 1A from that charger.
The phone will then draw enough current to power itself and, on top of that, charge the battery at the same time.
This current will typically be in the region of 800mA (0.8A) to 900mA (0.9A).
Under these conditions there is enough current to power all the functions of the phone, including WiFi, Bluetooth and GPS, as well as the usual GSM radio and the phone's other functions, as well as being able to charge the battery.
However, if the phone believes that it is connected to a power source with a lower rating such as a standard USB port, then it will limit the maximum current that it draws from that power source to between 400mA (0.4A) and 500mA (0.5A) as this is the maximum officially provided by a USB port.
In other words, the phone is intelligent enough not to overload a standard USB port but, when more power is available, it is able to use it.
The mechanism that HTC uses to detect a power supply capable of supplying 1A, as opposed to a USB port, is very simple indeed.
When the phone detects that an external power source has been connected, it checks to see if the two data lines of the USB connector on the bottom of the phone have been short-circuited.
If they have been short-circuited, the phone takes this to mean that a suitable power source has been connected providing a current of at least 1A.
If the data lines are not short-circuited, the phone assumes that the power is coming from a USB port or other device not capable of providing more than 500mA.
In practice, the way this has been implemented is that within the official mains powered HTC charger, the two data pins of the USB connector are shorted together.
As soon as you connect this charger to the Desire, the phone detects the short-circuit and knows that it is connected to a charger capable of supplying 1A.
This particular trick seems to be something unique to HTC rather than being a universal standard, although this is a bit of a guess on my part based on having looked at only a few other chargers.
What this means is that if you have a car charger that is rated at 1A or higher, your HTC Desire will still only draw a maximum of 500mA from this charger.
This problem is easily rectified by opening up the charger and soldering together the two centre pens of the USB connector so that the phone sees this short-circuit and realises that it can safely draw I higher current from the charger.
Unless you know what you are doing and fully understand what I have explained above, then please don't go fiddling around with your charger.
I have carried out this modification myself on a couple of non-HTC mains-powered chargers and a couple of 12V car chargers with 100% success.
I have, however, found that some 12V chargers, even though they are rated at 1A or even 1.5A do not result in the Desire drawing the expected current.
What I found was that the phone would draw only about 250mA and then, after I had shorted the data terminals within the charger, the phone would draw about 450mA but not the 850mA or so that I had expected.
I have yet to determine with certainty why this is but it appears that as the phone begins to draw current from the charger it is able to detect if there is even a relatively small dip in the voltage coming from the charger and, if so, the phone backs off on the amount of current that it draws.
I will be doing a few more tests in my electronics lab to try and get to the bottom of this and provide a more detailed analysis and, hopefully, a useful solution.
In the meantime though, I have at least solved the problem that I was having and, based on numerous forum posts, the same problem that many other people have been having with car chargers not effectively charging the Desire.

Snap!
I didn't see your post before making mine (above) but my experimentation agrees fully with what you've said.
You can do it the way you've described, by modifying a cable, or you can do it inside the charger itself.
Just make sure that the cable going to the phone has all four USB wires in it. Some of them only have the two power wires, so the phone will never detect the short circuited data lines.
Tim
If you do not want to open your car charger, you can always create a male to female adapter that shots D+ and D- on the female side like the one in the attached picture
Obviously, the charger needs to be able to provide the 1Amps that are needed. If not, it will at best shutdown in protection mode, at worst fry completely with a great chance of fire...
Interesting stuff...
I bought an official HTC car charger and noticed that the included usb cable, when plugged into a pc, does not allow data transfer, only charging.
Can anyone explain that ? Why would there be a difference in the wiring ?
They want you to buy an official USB cable I guess ? Considering any microusb cable works I'm surprised they bother
Maybe because they just put the two VCC and GND wires in there, thus saving on the cabling cost.
Ok how about this then......
I have a USB port I'm my car (to plug in music on a dongle I presume) if I use the USB lead from my charger supplied with the phone (which also works as a data cable) I get a the charging status icon on the battery bar.
So......
Is my phone charging at 1 amp on the car, and at home or am I getting 0.5 on both or something else?

If you check your battery stats by dialing *#*#4636#*#* and look at battery info, then you can see if it is charged by USB (max 500 mA) or at AC (more then 500mA)
I bought the official HTC charger, works perfectly.
thanks a lot for the explanation. I went for an uprated USB car charger but was still using normal cables to plug into it and the phone wasnt keeping up when bluetooth and GPS was on and was flat by the end of a long journey. Have tried the mod and phone is showing as plugged into AC so hopefully this is going to sort my issues.
So am I right in saying that, unless you get one which has been adapted as described above, there is no real difference between one in-car charger and another - none of them will be up to the job of keeping the phone full of jiuce whilst running GPS over a long journey.
Was thinking of shelling out for a Brodit kit, but at £50+, I'll stick with a cheap one.

Not really.
For the "mod" to work, your charger must be able to source at least 1000mA which most can't anyway.
So you first have to find a charger that does and then, if it's not already the case, short the D+ and D- cables together.
Note that this can be done by disassembling the charger (not being sure of being able to put it back together), by using conductive glue on the USB plug itself (a bit invasive) or by using an adapter like the one I shown in my previous message (but you need to do it yourself or have someone do it for you)
Hello. I'm trying to pick a car charger that would work with the galaxy nexus. from what I've read so far the samsung CAD300UBEB/STD model seems to do the trick but a few review says that the battery discharges faster than the charger can charge it back under heavy usage. can anybody confirm or deny this?
and also, I would like to know if that same charger would work for a galaxy S2. I'm looking for a charger than can be used with both models because I have both phones. the listing of models in amazon website doesn't list the nexus or the S2. so I want to make sure before buying it. thanks!
I'm also interested. I was just looking at this discussion on Reddit taht goes a little more in depth

The motorola charger listed there seems work well for the nexus and also for the S2 according to amazon reviews.
I went with one of these and a USB cable, and it seems to work just fine. Also gives me a spare USB port for additional charging.

I have the Motorola one already (the one with the blue LED) when I had my Droid 3, now it can't keep up with the Nexus' power drain. Just using it moderately on 3G only in the car today had it drain 3% over 40 minutes.

not according to this guy
I have a galaxy nexus cell phone which requires probably around 1.5 Amps when using GPS. The phone does not come with the car charger. It only comes with a 2A wall charger. My temporary solution has been to use a car power inverter that has house-type outlets on it (which I already had) so that I can use the wall charger in the car. This has been working fine, but for obvious reasons, is not my desired long-term solution.
Enter this piece of crap. Now, the phone and only requires a little over 1 A with GPS. With the real two amp wall charger, I am able to both run GPS and charge the battery pretty darn fast. But, with this charger, not only can I not use GPS without draining the battery, but even when not using anything special, the battery charging times are horrendous.
Stay far, far away.

Wow... granted, I am not using a GPS, but I never really checked the charge times. I don't rely on it for a fast full-charge.. usually just plug it in on the trip home and charge as much as it can until I plug it in at home.
Thanks for the heads up.. I am gonna have to keep an eye on it now.

I've researched this pretty thoroughly, and the key question is whether or not your GN shows "AC" when you check the Battery status, or if it shows "USB."
With most car chargers, it is seen as "USB" as if it's plugged into a computer, and will draw minimal current, generally not enough to keep up. I had 2 different chargers in my cars, none of which showed as "AC". I bought and then returned the Griffin PowerJolt Dual USB Micro Charger - it also showed as only "USB."
Finally, in one of the other Android forums I've been monitoring on this issue, somebody came across this one:
HTC T-Mobile myTouch 3G Car Charger
$3.12, free shipping. Mine came yesterday, plugged it in, and finally my GN showed charging as "AC".
Hope this helps!
When your smartphone shows your charger as ''USB'' this means that the USB data lines in the charger are not short-circuited. Then smartphone reduces its charging current to avoind any problems with USB laptop power sources
I made some experiments to check this point : see http://78michel.unblog.fr/?p=184.
I also opened a car charger and short-circuited the data lines on USB the plug . That way I have solved my previuos charging problem in my car during long trip.

i've used it now 4 times, twice on a trip from south florida to orlando.
It charges the phone just as fast, if not faster than my home charger. On the way back, my phone was at 35%, within 2 hours it was back up to 100%. No GPS and a couple phone calls.
on the way up, GPS on and it never dropped below 97%.
so i can tell you without any doubt what-so-ever that this charger works perfectly with the galaxy nexus and will charge it with Navigation and phone calls running.

I bought a charger very similar to this one and it works great in my car. I make sure any charger I get is rated 5V DC at 1000mAh at least.
I have 2 USB 2.5A dongle chargers, one by Belkin and the other by Kingston. Both register as charging via "USB mode" and do not provide sufficient power while the phone is in use(loses charge usually). I also have that Motorola Rapid charger but the way the cable is designed it tugs on the USB port and comes loose often. I ended up just using the normal USB cable that comes with the phone and a 140W power inverter. Granted, it's not the most compact of devices, but it works well. I got it from Walmart for $20. Here's a link to it:
http://www.walmart.com/ip/Schumacher-XI14-Power-Inverter/15140199?findingMethod=rr
(and yes, using a power inverter will have the phone registering as "charging AC" and give a full proper charge.)
I'm using a Scoshe (sp?) dual USB port charger I picked up from Staples. It has a 1amp port and a 2.1amp port and I just use the micro usb cable the GNex came with

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.
Dual USB Port with a 1 amp port and a 2.1 amp port (2.1 amp port is for tablets or power hungry devices - like the phone while navigating). http://www.amazon.com/gp/product/B0056VNVV8/ref=oh_o01_s00_i01_details
Charging Only USB cable:

Thanks for this. It's been driving me mad how car chargers and cables are so inconsistent. Pun intended.
Seriously, why can they come up with a standard and call it a day?
I have a had a few GPS/Pandora runs. Even while it says AC charging and my charger is rated for 1A, it drains the battery by 300-400ma.
What is the best solution for quick charging the Galaxy Nexus in an automobile?
I have started to use 12-220 volt converter so I can use wall chargers.
I have bought a few of the low profile car usb chargers but they were never recognized as an AC charge. Come to find out, it was the USB cable. I bought a usb charging cable from Amazon last week and it goes in the USB charger and the phone does not think it is a USB charge. I have not timed it but it is recognized the same as the wall charger.

+1 .. this solution has been working great for me, as well.
I've been getting 2.1A car chargers (look for ones for the iPad), most of the ones I had prior to this were 700mA or so and they can't keep up with my 1A phones. Be careful of dual port chargers advertising 2A, they may only be 1A each and may be "optimistic" about that rating. And don't worry about getting one rated for too much current, the Galaxy Nexus won't pull more than an amp no matter what the charger rating.
Some really good solutions here and thank you all for the help.
I'd really hate to use an inventer in my car just to maintain a clean install, so that really isnt an option for me.
Was really hoping to be able to use a off the shelf car charger with the correct pins to trick the GNexus into thinking that it was charging from a USB port, but the above solution should work well with using a socket USB charger.
I've never run into a car adapter that looks like a USB port, including the VZW charger with a spare port or the cheap 2.1A chargers I got from Amazon. My guess is that a charger not built correctly and leaving the data pins open only supports ~500mA anyway. Even if that's not the case I have a moral objection toward buying a cable to fix a design flaw in another cheap product - but that's just me

Make sure the charger has the IC (rapid) chip. I use this one:

I've heard that Motorola one mentioned a lot as a good one.
The nice thing about having the low-profile usb plug is (a) it is low profile, (b) I can use it to charge other devices. The charge-only cable is only about $4, so I had no issues buying it to work with this to charge as an AC charge over a USB charge.

I have this one and it charges just like it does from the home outlet and its says "AC" charging. I bought another 8 for family and friends and they all love it.
I think I've figured out the disconnect, I've run into chargers that appear as a USB host which limits the charging to 500mA on previous phones I've had.
You guys are concerned about USB vs. AC charging mode. Of the chargers I've got, this one lists as AC while the rest as USB. However, the fact that the other chargers all work just fine keeping up with GPS+streaming music indicates that the USB vs. AC really has no bearing on the charge current delivered. I'd stay away from charge-only cables just because they'll get mixed in with your standard USB cables and you'll knock yourself out wondering why they don't work. On the other hand, if you really want AC in your battery info order the one I linked.
I keep it in my car... i think I've heard on other threads that USB charging doesn't keep up with GPS (for Directions). Any verify?

What's much more important is the rating on the power source. The GN can pull up to 1000mA, if your charger is only rated for 800mA (like many car chargers) it doesn't matter if it's in AC mode.

makes sense.. the one I use has dual usb (1.0 and 2.1)
You went and gave me a project for the weekend, and once again science prevails over anecdotal evidence. I took each of my 5 chargers and hooked them up to a 12V power supply that measures current. I then recorded whether the charger reported AC or USB, for the ones with USB I modified a right-angle adapter to short out the data pins, and I measured the current. The contenders:
Verizon Wireless Dual Charger
XTG Dual Port Charger
Griffen Powerjolt Dual USB Charger
Griffen Portjolt Micro
CostMad Dual USB Charger
The VZW model was USB out the external port as I had tested before, however AC out the built-in cable which I hadn't bothered to test. It pulled 0.25A @12V via the USB port and 0.59A via the cable. Hmmm... A hole develops in my previous observation. While I had used this on a long car trip with no issues, it was via the built-in cable.
The XTG was new, I hadn't used it before as it's in the car I rarely drive. It reported USB and 0.22A. With the adapter to make it report AC it pulled 0.48A.
The pattern was set. I had expected the Griffen adapters to be built more appropriately but the dual charger reported 0.22A without the adapter and 0.42A with. I had used this without losing charge in the past so this was surprising to me, but it's possible I just wasn't drawing as much current because the screen was dimmer or something.
The compact Griffen adapter (which is great for a laptop bag, BTW) pulled 0.21A and 0.47A respectively.
The cheap CostMad adapter was the only one that performed well out of the box, both reporting AC and pulled 0.57A.
In theory, a perfect adapter should pull 0.42A. Anything more is waste, anything less means it's not keeping up. I have doubts about the Griffen 2x allowing for a full amp, but the VZW and CostMad chargers are pretty lossy. What's even worse is that I'm pretty sure the VZW charger is rated for 800mA (but I can't find an actual spec on it) which would mean that it pulled the most power for the least current. Not that this really matters unless you've got an electric car.
Sorry for misleading you earlier, I should have checked the other port of the known-good VZW charger and probably doublechecked the numbers on my other "known good" charger. Still hating cables that work for charging but not for data, I ended up modifying each of the chargers to short the middle pins (except for the VZW one). If I didn't have the soldering iron for this, I probably would have gone for some of these instead.

+1 to those recommending this one. I have this exact model and it does indeed charge at the "AC" rate, about twice as fast as the "USB" rate.

I keep it in my car... i think I've heard on other threads that USB charging doesn't keep up with GPS (for Directions). Any verify?

The Motorola one will charge even when using GPS. I have a friend I bought one for that uses his GPS all day and loves the Motorola charger.
Hi,
I'm the owner of a new Z1C and I'm wondering if it would be harmful for the battery to charge it with a normal usb cable different from the one supplied by Sony. I can imagine it should not be an issue, but I also tried to connect a older headphones to the Z1C and a popup warned me about a "Non-Sony headphones", so... I prefer to ask to be really sure.
Can I charge the phone with a normal usb cable? Thanks in advance,
I've actually been using the cable that came with my Kindle and it works perfectly, no issues at all. It charges quickly and I don't get any errors on my phone. I've also used the cable that came with my Ipega bluetooth controller and it works as well.
I would however recommend staying away from the wall adapters they sell at CVS/Walgreens near the front, and possibly the cables too. I noticed that whenever I plugged in my phone using the wall adapter, the touch screen wouldn't function properly and acted like every time I touched the screen, even if it was to quickly swipe, that I was pressing instead. Horrible.
I also use a non-Sony charger and it works fine. As long is it is a micro-usb charger it will be fine. Headphones on the other hand are different though like you said. I tried a pair of earphones from my older Sony Ericsson X8 and it tells me it is not a supported so yea...
Since the USB specification is quite rigorous there should be no problems, except for very cheap adapters which provide an unstable voltage.
Hello @dramatictone;,
It's safe to charge it with another charger as long as the ampere of the charger is not higher than 2A. However, most aftermarket chargers are rated at 1A, which means that it'll charge slower.
It's also important to buy a quality charger with the safety marks; if you don't want to risk burning down your house while charging over night. Don't buy those generic China chargers, they're not safe to use.
I hope my answer cleared any doubts.
Have a great day,
GethPrime
Thank you very much everybody, I'm more confident now

No problem, but remember to buy a quality charger and you'll be fine. However, any MicroUSB cable will be fine for charging, even cheap China ones

Yep. I had planned to use the official Sony charger at home and the oldie Samsung Galaxy S charger (or even a microusb cable) when charging the phone at the office, but I wanted to be really sure first: I've been using the phone for three days now and I have only had to charge it just once, so I don't want to damage the battery now that I have a phone that lasts more than one day

Note that the old Samsung chargers are rated at 0,7A, so it'll take some time to charge. Other than that it'll work just fine.
Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?
Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)
I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...
Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.
Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
