I've just driven over 400 miles...
I was using my Desire with Co Pilot to navigate me from Scotland to Bristol...
The phone was in my phone holder which is placed in the cigarette lighter so the phone can apparently be charged at the same time as being held...
The phone showed that it was "charging" and yet it still ran out of power....
That's right.. the CHARGING phone RAN OUT of power and switched off!!!!!!! TWICE!!!!!!!!
Has anyone else experienced this? I can't imagine that this phone uses more power than the charge being applied?!
I used my Desire as GPS (with Copilot) the phone had 70% - 80% battery and after sometime it actually charged to 100%. Maybe there is some malfunction in your car charger or just not making a good contact in cigarette lighter plug. Check if charger's led lights all the time.
car chargers trickle charge so they prob couldn't keep up with the demands of CoPilot on the phone

You need to ensure that the car charger is rated at 1AMP at 5V otherwise it will as stated only trickle charge. I've heard this story on other devices. Do you have a genuine HTC charger?
Also if the device gets to warm, it will stop charging in order to avoid damage.
Thanks for the reply guys!
No, it's not a geniune one... I tried 2 different ones, both the universal holder/chargers from Mobile Fun..
So far they've both been fantastic until this little phone came along...!
Connections have been fine, which is the strange thing..
It did get hot though, so you may be right Ardsar... Any way of keeping it cooled?
Buy OEM...

i have had the same problem plugging it into my computer and using it at the same time killed it.

Same as what others say as well. Your car charger doesn't supply enough amps to keep up.
Ofcourse it gets really hot, navigation is one of the most heavy thing you can do on the phone. And while doing that you charge it at the same time in perhaps a warm car as well.
But, get a 1A charger, not a 500mah like most are.
Same goes for hooking it on the computer, the usb port might not give enough power so the phone can drain itself when doing real heavy stuff.
Plugging something in does not guarantee it will work, you have to know what you plug in

Of course you will - USB ports can only supply upto 500mA if you have nothing else connected to the USB HOst.
Same story for me.
I got a 550 mA car charger, and battery wasn't charging but slowly discharging (about 5-10% per hour) with navi+HDSPA.
Thought, well, 550 mA is not enough, let's see the plug charger from Desire box: that's 1000 mA. Let's go get a 1A car charger.
Got this www . p4c.philips. com/cgi-bin/dcbint/cpindex.pl?ctn=DLM2206/10&slg=it&scy=IT (saw off spaces) which is rated 5V-1A.
Plugged in, started navigating+HDSPA for satellite layer, and still wasn't charging but discharging at a rate of about 4% per hour.
I'm really annoyed 'bout this, I spent 20+15€ for both chargers, I do not want to spend another 25€ for OEM charger....it's unbelivable that I'd finish to buy 60€ of chargers to find out one that do not let battery deplete.
As a final test, I'll try a different cable from original HTC sync cable included in the box...let's see.

Can anyone who has used this confirm it will manage to charge fully even while the Desire is running a satnav program?
Why don't you plug in your normal charger and start running a navigation demo or something.
Not sure if that uses as much energy, but I think it most probably will. The original charger outputs 1A.
If the socket charger does the job, but not the car charger (read: you can also run a navigation demo in the car using that charger) your car charger might not be supplying enough energy as it should.
Or you can use a multimeter and see how many amps it outputs. But the pins are a bit smallish
Tried with another cable (not the original sync one) with just power wires connected, same story: I'll try with the original wall plug charger and see if it does the same or not, as both the Philips charger and the original HTC wall charger are rated 5V-1A
It does get very hot. I used my gps for 9 hours in a row and at the end it got too hot or something and the phone just rebooted.
Still It wasn't because the battery had run out of juice it was still good.
Also it was streaming music over bluetooth at the same time.
Used Nav for 1 hour this morning on the way to work while charging from the official HTC car charger. Phone now sat on my desk, battery reporting 100%.
The phone did get pretty hot though...

FYI, not all chargers are equal. I believe that HTC devices need a combination of pins to be connected on the USB port to "tell" the phone that it's connected to a real charger and not a USB port, otherwise the phone will only pull 0.5A, regardless of the output capacity of the charger.
This always used to apply to older HTC phones, and I can't see why they'd change it, so it's quite possible that your 1A Philips charger will not charge the same as my 1A HTC charger...
If in doubt, OEM

That's what I thought, as I imagined that: I hoped that another cable I have, which has USB on one side and a 2 poles connector on the other side on which you connect various connectors, would be recognized by Desire as being a pure power cable. I wasn't lucky.
Since OEM is out for 25€, I tried with non OEM before to save some, but till now I buyed 35€ worth chargers, I'd have to stick with OEM
But now I'm really reluctant on getting OEM, since I do not want to end with spending 60€ in order to have my phone charged while navigating....I'll try to tinker some, and if I'll find out how, I'll report
I had the same problem by using a 1.5A car charger which is working great with iPhone.
As for the PC USB charge... are you sure it can't output 1A to charge the device??

USB2 specs do say that ports shall provide max 500 mA, ehnce motherboards have this limit.
BTW, here's a discussion I've found about the "cable" problem
forum.xda-developers. com/archive/index.php/t-643808.html
For HD2 (which is actually the model to which HTC CC C200 is dedicated)
I'll try to tinker with some cheap cable and see if this works.
I've noticed this happening any time I tether via USB or use GPS navigation while plugged in. Even though I'm connected and charging, I slowly but surely discharge. This weekend I used Google Nav for 2 hours and lost 20% of my battery while charging! On Juice Plotter, I notice the green charging glow at the bottom is a more transparent shade of green (as opposed to solid green when solely charging). Any ideas what causes this or how to avoid it? It seems to be recent.

Let me guess, you're charging off a USB port in your laptop, or using the data cable that came with the phone in your car charger?
Not all USB sources (or cables, for that matter) are created equally. Most PC/laptop ports put out 500mAh, half of what the Evo is designed to take (the factory AC adapter, the wall plug, is 1000mAh, aka 1amp).
Since it's only getting half the draw it can't quite keep up with how much power you're sucking away from the battery. This is usually only present when using the device heavily, such as with the screen on and GPS or WiFi/3G actively running.
The charging indicator (at least on Sense) indicates if it's getting the full "AC" charge (1amp) or if it's getting a reduced current charge. Sounds like that's what you're noticing.
My wife's Samsung Moment charger is 700mAh/0.7amp, and it can keep my Evo steady during use (it's powering it for 3G+WiFi tether right now), but it doesn't really charge fast at all, basically it just keeps it from depleting.
I've been meaning to try one of the USB Y-cables that join 2 standard USB ports to one female port for combined power of 1amp, but I'm not sure it will work as I hope. Anyway, I'll report back if I get around to it.
Otherwise, use an actual 1amp AC adapter whenever possible. Shop on eBay, chargers are stupid cheap. Just look for one that says it can do 1amp/1000mAh. If you're using the phone at work and want to have a convenient charging source, get one of the $20 docking cradles with an AC adapter on eBay. If it's in your car, any 12v USB charger should work, as long as you use a proper pass-through charging micro USB cable and not a "data cable". There's a slight difference in how the pins are wired inside. The Rocket Fish brand of micro USB cables are known to work (that's how I charge mine at full power in my car).

I'm using the included charging cable. Doesn't that have full capacity? I also use a standard USB adapter in the car. It seems like that would be able to output the correct amount of volts.

I had the same problem until I noticed how hot my phone was using the nav. 13 hour drive. I purchased a vent cradle for the car and so that it can stay cool while in use and charging. While the other guy may be right theoretically, its not right practically. The evo will shut off its mini usb hub once it starts getting dangerously hot so that it won't damage your phone. Long story short make sure your phone is at safe temps no need to buy another charger for your evo. keep at cool temps so that phone won't cut off power supply will even shut your phone down if its way to hot, happened to me in atlanta not fun.

When you say "included charging cable" do you mean the wall plug that came with the Evo or just the cable with a USB connector on one end and a micro USB on the other end? Because THAT cable is pinned as a data transfer cable and designed to relay only half voltage no matter what you plug it into. I know, because it only charged my Evo at slow speed when plugged into my USB car charger. Once I replaced it with the Rocket Fish cable it charged at full speed.

See above. While I agree that heat will kill the battery and possibly trigger a shutoff, I don't think that's his problem. If you use the wrong cable or charger you will only get half charging current.

I mean the USB cable that comes in the box with the EVO that plugs into the AC adapter. Maybe I will look into a new cable then. Hmm.
Edit: Those Rocketfish cables that you mentioned seem to be ungodly expensive. No way in hell am I going to pay more than $5 for a USB cable. Any alternatives?

This is the one I got: http://cgi.ebay.com/ROCKETFISH-MOBI...ARGING-CABLE-/350384355972?pt=PDA_Accessories
$3 shipped
And there are 2 USB cables that came with the Evo (mine anyway), a thick one that was bundled with the wall charger and a thin one that's intended just for data sync. The thin one doesn't seem to charge at full speed.
If you're using the other one and it's STILL draining then maybe there is an issue with heat or something, like the other guy said. Is the phone SUPER hot at the base, where the kickstand is, when this happens?
OP - I am having the same problem. I'm 95% sure it's caused by something wrong in CM6 regarding how it handles USB charging. Past few nightlies I have been leaving my phone on the charger doing NOTHING overnight and it goes dead.
This CANNOT be due to lack of charging strength:
#1 the same exact charger worked perfectly in the past, before I flashed a certain nightly - not sure which one exactly it started in
#2 if it was charging, but slowly why in the world would the battery drain when I have it underclocked to 245 mhz and the phone is sleeping with screen off?
On my standard charger that came with the phone it is working fine even though it's a USB that plugs into an adapter - not sure why this doesn't work with my other one that I had from another phone since it worked perfectly before. Something is definitely odd with CM6 and USB charging.

I've also noticed lately that my phone will charge insanely fast. Like from 30% to 90% in half an hour.
Sprocket - stupid question here... do these Rocket Fish charging cables also handle data transfer just as well as the stock micro-usb cable that came with the phone or would someone want to have one JUST for charging and keep their stock cable for data transfer purposes?

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.

this is what i bought: http://www.amazon.com/gp/product/B000S5Q9CA/ref=oh_o03_s00_i00_details
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:
http://www.amazon.com/gp/product/B003VYBCAY/ref=oh_o00_s00_i00_details
This combo has me as "Charging AC" whenever I am in the car and I still have a port open to charge another one of the 27 or so different electronic devices that seem to clutter my life!
Some details on the changes I made on my car chargers

Just like bmolly said, it works as AC is you use a "charge only" 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

I've got a charger similar to http://www.ebay.com.au/itm/USB-Car-...ccessories&hash=item4ab18358f4#ht_1638wt_1392
All I had to do was undo the screws at the top, put a bit of solder between the middle usb pins, and my phone recognises it as a AC source rather than USB.
There has got to be a standard car charger on the market with the middle usb pins already soldiered!
I found this on Amazon which advertises itself as a rapid charging device.

Make sure the charger has the IC (rapid) chip. I use this one:
http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA
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.

I'm using the same one and it works perfect. Charges even when GPS navigation is running.
Make sure you select Amazon as the seller though. I heard there are a lot of fake ones.

+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.

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.
Any way to disable rapid charging?
I have a generic USB extender and used it to extend my charger cable by a couple of feet. When the phone showed "full charge in 5 hours" I realized it's making the charge speed extremely slow. The USB cable is a regular sized USB male on one end while the other end is a regular sized USB female. You could use that to slow down your charging to about the speed you'd get by charging from a USB 2.0 connector on any PC/laptop.
One the same note will using a standard charger from other cell phones (that I have like 300 of) and the cable that came with phone cause any problems or just charge slow. I travel a lot and have several USB devices I bring and don't want to bring multiple chargers if I don't need to.
Thanks.
It will just charge slow.

You need a compatible charger for it to fast charge. Using a regular charger wouldn't put it in that mode. I wanted to know if there was an option to turn it off with a compatible charger.
Why do you want to turn it off.
I could swear I saw something in the framework to disable fast charging but I'm not 100% sure.
I'll try to remember to keep an eye out for it after the December updates drop from Google and I have to redo my framework mods.
As far as options in the GUI go, I don't recall ever seeing any option to disable fast charging.
To answer another question, someone may want to disable fast charging to ensure their battery lasts longer (short term + long term). Or to prevent overheating when charging in the sun. And other reasons too.
You could always buy a MicroUSB to USB-C adapter. Or the phone may have come with one too now that I think about it.
Then use an older MicroUSB charger to charge your phone.
Charging via computer is only like 500mAH compared vs. 2000+mAH charging from the stock charger.
Count me amongst the club who would prefer to slow-charge my phone overnight at least.
And possibly slow my car charger down to maybe just 1000mAH to prevent overheating while the phone is docked underneath my windshield under the hot sun.
