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...

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.
Hello,
FYI, I use Galaxy S GT-I9000.
I bought on ebay a charger for car, offering 5V and 700mA (as the sector charger).
The product: http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=290453364639
Unfortunately, I loose 3% of battery load within 20 minutes. I observed this behaviour with copilot 8 and Google Nav.
Did one of you guys solve the issue ? Do I need a charger that is not a USB-cable like ?
Would a 1000mA solve the problem ?
IE : http://www.dealextreme.com/details.dx/sku.40470
Even if a comment says that : "This will charge my HTC desire, however when using the GPS it actually fails to sustain the battery and it goes gradually flat "
I've never run into a problem with this myself, but I've always used the adapter that has the cord on it and ends with the mini USB. I'll have to check mine and see what the mA is on it sometime.
I can safely assume that the charger does not have 1000mA output... so chances are it will be more or less the same as your existing 700mA charger (which, of course, i
Of course, it's only 3 bucks to lose and you still earn an extra charger.
You may search from NeTimes for Universal 145cm Long Cable Car Charger - microUSB, it's more expensive but I am using it with HTC HD with Google Maps on for an hour without losing battery.... the phone gets pretty hot though.
If the phone does charge on usb it should work on 700mA as well. usb is only 500mA
I just bought a generic USB wall charger and it's taking much longer to charge than the htc charger that came with my EVO.
I'd like to determine the amps/ma the charger is actually putting out. I don't have a multi-meter, so I am hoping there is a hidden menu or app which will tell me what the phone sees.
Any suggestions?
You can download aLogcat and watch for the current usage, it should post it every so often. It should also say on the charger somewhere too, the stock wall charger is 1000mA
I tried this and found nothing showing charge rate, only the battery percent.
A standard usb wall charger should equal how long it takes to charge if you were plugged into you pc. If it is taking longer than that then you got a super el cheapo charger that puts out less than 500ma (milliamps).
I would be carefull too, cheap usb wall chargers are not know to output clean power and have killed devices. By overvolting/charging them.
I have been doing some testing lately with the htc charger and a pc and have come to the conclusion that the htc wall charger pushing 1 amp (1000ma) charges the battery too fast and doesnt allow for a "strong" charge. Meaning your battery will drain faster. The htc charger is, i believe not meant to be your everyday charger, only a boost charger to get you charged back up quickly.
This is common battery knowledge when it comes to charging... you can charge a battery too fast, and a slower; 500ma "trickle charge" is much cleaner and better for your battery.
Some maybe argue this, and thats ok, these are just my personal findings.
Sent from my PC36100 using XDA App
I'm not seeing that info in the log either.
The charger had a weird range of 250-1000ma.
Yeah I think I'll invest in a better charger just to be safe.
Thank you both for your replies.
Anybody come across a car charger that is high current like the HTC wall charger?
Most car chargers are classified as "rapid".
Anything designed to charge an iPad (2.1A versus the typical 1A) will give you plenty of juice. I use the Scosche reVIVE II with Pandora, Bluetooth, and GPS Navigation all on and still have enough power to positively charge my battery.
Fair warning, though, this will cause the phone to get real hot (I've had the overheating warning lights flash twice so far), so make sure you have plenty of ventilation around the phone, keep it out of the sun, etc etc.
Any charger that is at least 1 amp. will do. The phone 'pulls' a max of around 0.85 amps. No need for more then 1 amp.
If it has a replaceable cable, it must be the heaviest gauge, shortest cable, that you can use. I have seen long cheap thin cables that drop over a volt, and the Thunderbolt charges really slowly.
The charger or cable have to state that they for rapid charging. To rapid charge, you need to have the USB D- and D+ lines shorted. If that are not shorted, the Thunderbolt limits the charge current to around 0.35 amps. thinking it is connected to a PC. If they are shorted, letting the Thunderbolt know it can be rapid charged, you get up there around 0.85. You can easily modify the charger for high rate if it is good for at least an amp.
And in the end is heat. Heat and lots of it. It will damage the battery. So put it out of the sun and in cool air like near a vent.

Review off Amazon
Genuine Motorola charger in retail packaging. 4.75-5.25V 950mA output, works w/ most micro-USB phones like Incredible, etc., June 11, 2010
By
David Pearlman "sound fanatic" (Arlington, MA) - See all my reviews
(TOP 500 REVIEWER) (VINE VOICE) (REAL NAME)
Amazon Verified Purchase(What's this?)
There are so many sketchy sellers selling phone chargers out there, that it can be a bit scary. The problem is that if the charger is poorly made, the output of the charger can be out of spec and can, in some cases, fry the phone you connect to it.
For that reason, when it comes to phone chargers, you should stick to name brands. (They are all made in China, but the name brand ones are usually subject to stricter QA).
When I found this charger on Amazon, SOLD BY AMAZON, I jumped on it. It's a MICRO USB car charger, made for Motorola and sold under the Motorola name, in retail packaging. The rated output is 4.75-5.25V and 950mA.
This charger should work fine with most any phone that uses the MICRO USB connector. The key number to pay attention to is the second one, the rated amperage. This is the MAXIMUM amount of current that the phone can request from the charger. A typical USB port on a PC provides as little as 100mA, and few provide more than 500mA. So this charger should charge your phone faster than when it's connected to a PC. A few phones out now can use up to 1000mA. But that just means they CAN use that amount. If 950mA is provided, they'll still charge, just a bit more slowly.
Note that the amperage (second number) merely tells you how much the charger CAN supply, if requested. The phone itself is responsible for asking for the current. That is to say, if this charger can provide 950mA, but your phone can only use 300mA--no problem. Your phone asks for 300mA and the charger provides all of what is requested. If, on the other hand, your phone can use 1000mA, this charger will provide all it can, which is 950mA--a wee bit less than the max asked for. That's also not a problem; it just means your phone will charge a little bit (not much in this case) more slowly. The rated voltage for this charger is presented in a range of 4.75-5.25V. The "ideal" voltage for a USB charger of any type if 5V. And most chargers for home use are rated right at 5V. But car chargers work in a noisier environment and thus you have the range. This is where a cheapo charger can really do damage, as some of them are poorly regulated and can provide voltages that are WAY out of spec. Again, when you can get a name brand charger from a seller you can trust (Amazon) for such a reasonable price, it's very foolish to consider the cheapo no-names.
This is an excellent quality name brand travel micro USB charger at a price that beats the no-name junk from third party sellers. What's not to like?
BE SURE TO ORDER IT FROM AMAZON AND NOT ONE OF THE THIRD PARTY SELLERS, as some of those have been known to make mistakes with respect to what they ship relative to the listing. I can confirm that Amazon is shipping the P513 /89143N charger, as pictured.

From what I've read in the past here on XDA and on the reviews for the charger (on amazon) you shouldn't have a problem. The second review for the charger on amazon states that the reviewer was looking for a charger which actually charged his phone will using GPS and that he found it. It's a very well built charger and cheap. It's made my Motorola and sold by Amazon so buy with confidence.

It does indeed charge. I've had it since my original Droid and was concerned when I updated to the TB but it will charge the TB no matter what you're doing (I've had Nav running while on a phone call with BT and searching the internet and it still showed it was charging). Just be prepared for your phone to get HOT!! Great charger.

Actually, the phone will pull more than 850 mA. You're probably basing that on using a battery monitor, which only shows the flow of current into/out of the battery. I've seen 800 mA into the battery at the same time I have display, GPS and a phone call going, which is definitely more than an additional 50 mA. It wouldn't surprise me if the phone can take advantage of something more than 1A, since I see a battery drain of more than 200 mA with all of that going when not on the charger.

No, that was measured at the 5 volt power supply, based upon a lab power supply. I did a lot of experimenting when I developed the charger and phone mount for my motorcycle. And to get the 850ma from the power supply, I used a very short, maybe 8 inch, USB cable, and a charge voltage close to 5.3 volts. With 5 volts at the power supply, it would only pull about 650ma from the power supply. That was due to the voltage drop in the USB cable. With the 5.3 volts at the power supply, I was getting close to an actual 5 volts at the Thunderbolt. I never measured the current at the battery, but I could see it being a bit more then the 850ma in, if there were a switch mode supply in there.
Though I like the Battery Monitor widget as a rough guide, I never tested to see if the battery current and the battery monitor are accurate.

Absolutely.
A PC USB port is limited to under 500ma. The Thunderbolt appears to to limit PC USB draw to about 350ma. I haven't measured the actual current in the HTC charger, but it is a high current charger, and charges my Thunderbolt very quickly. Battery Monitor widget shows high battery charge rates. I suspect it is getting near the max rate up near 1 amp.

That doesn't mean much. That is the MAX the charger can output. The amount that the Thunderbolt will pull varies. If it thinks it is plugged into a USB, it will be less then 500ma. even if the charger is capable of 10 amps.

and the whole thing about the D- and D+ shorted together, i do not believe. the HTC cable that came with the phone does rapid charging and i use it for data all the time too. if they D- and D+ was shorted, i would not be able to use it for data transfer. not unless the HTC charger shorts them internally inside the charger.

Yes, it is hard to find the current info online or even on the package sometimes.
Yes, it is shorted in the charger. I have seen it done in the cable and the cable can't be used for data of course. Not sure why anyone would do that, but they do.
Hello everyone !
I use 9100G for the navigation while driving and noticed that my car lighter / usb adapter declared as max 1000 mA doesnt give enough power to charge, or at least keep the battery at my phone while GPS is on (screen also on all the time).
S2 doesnt drain battery too fast but it drains it percent by percent and if the route is long then it wont last enough.
Thatswhy I bought dual USB car adapter - one port is 1000 mA, other is for the tablets 2100 mA.
Tested the one with the 1000 mA and its same story as with my previous adapter (no wonder since output is same) but Im wondering can I connect S2 to 2100 mA port ?
It surely have enough power to keep the S2 alive and probably to charge it in the same time but Im not sure will I damage the phone and battery ?
Any real life experience about this theme ?
ps
I have read existing threads but no one specified that used 2.1 A with S2 without problems
Thanks m8s !

There is a good chance that 2100mA might damage ur battery buddy coz when the output current is more than standard then the battery heats up too much than normal. One of my friend's battery was damaged using a charger with diff output current.
You can freely use 2.1A charger. Your handset will control charging current and it won't take more mA than it needs.
Don't know exactly how it's going with i9100G, but i9100 can take up to 650mA current and no more, doesn't matter what source you have. And that's hardware limitation, you can't change it with kernel.
For you, I can only say - check if your phone sees your car adapter as AC charger or USB connection.
When it is seen as USB, it draws from source up to 500mA. To make your phone see your adapter as AC charger you need to short out data pins(2 center) in USB cable. It's cable white and green. After that it will take more power but still I guess it will recharge slowly.
I have preety cool power source [email protected] but still I don't mind modding it to MicroUSB because it will charge as fast as stock 0.7A charger. That's lame :/
You can put it on 100A charger, it will take only 650mA.
Wrong voltage, or some noise and static electricity can kill your phone, not charger strength.

Be aware of knowing that some navigation apps uses more CPU than others. For example in my country (Poland) is popular a navi called Automapa. It`s great but it uses CPU more aggressively than other navi apss and my phone even if on efficent power adapter is loosing battery. On Sygic/TomTom the problem doesn`t exist.

It surely have enough power to keep the S2 alive and probably to charge it in the same time but Im not sure will I damage the phone and battery ?

As several people pointed out already, you can safely use 2100mA port. The 2100mA is the max amount of current the charger is capable of supplying. The phone's internal circuit (i.e. resistance) will determine how much of that 2.1A is drawn to charge the battery.
With that in mind, you will not see any difference between using 2100mA and 1000mA port, because 1000mA is already higher than what the phone will use, which is around ~650mA. Thus, if you couldn't charge the phone while using navigation on 1000mA port, you will experience the same thing on 2100mA.
Of course, this is assuming that the 1000mA and 2100mA ports indeed output 1000mA and 2100mA respectively.

Thanks for the reply, I ve checked the forum thoroughly but didnt found exact answer, anyway I tested it by myself and reults are
1000 mAh is not enough to give sufficient power to charge a phone while GPS is on (screen on) with WI FI and mobile data
2100 mAh is enough to give sufficient power for the task
Phone perform normally, slight heating under the camera at the back side but thats common while charging anyway
Thanks for the reply

It sounds like the 1000 mAh port may be supplying something less than 1000 mAh then.
Oh Well. As long as 2100 mAh port works
Check when charging with 1A and 2.1A if phone see connection as USB Charger or AC Charger
