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?

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 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.

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?

Sorry I was unclear - the other cable I have that is the problem is one from another phone but the same type, and up until recently it worked perfectly.
The Samsung charger adapter which comes in the box is very slow in nature. It take more than 2 hours to charge my phone. I was wondering if I can use the following Nokia brand chargers which are fast chargers?
Nokia Charger Adapter CA-146C
Nokia Fast Micro-USB Charger AC-10
It won't make any difference the phone decides what current it draws from the charger, so it'll take just as long to charge.
Are you really sure about this? Can you link me to some articles which confirm this.
Even I was thinking about purchasing AC-10 charger from Nokia.
How fast is the nokia charger?
0-10% -> 100% in an hour or less?

I'm not sure about this. I have a friend with a Blackberry Playbook and he reckons his phone charges much faster if he uses the charger from that.
The "stock" S2 charger is 700mA - it doesn't take a genius to work out that for a 1650mAh battery this will take about 2.5 hours to fully charge the battery under ideal conditions (phone off) or anything from 3-6 hours with the phone on, depending all what's running or if you're using the phone while it's charging.
Which is all pretty ridiculous - ok we're comparing apples and oranges when we compare a S2 to the likesw of a Nokia, but I do miss the days when I could charge my phone in an hour and have it last two or three days. I thought my Blackberry was bad but at least I can usually squeeze a full day out of it...
The only wall wart I had lying around that was more than 700mA was a 5V 2A supply. I've tried with that which works, but the phone chokes with a "battery overtemp" warning after about 10 minutes - which tells me I AM pumping more into the battery than it can handle. This would suggest that there IS a happy medium where we can optimize the battery charge time - I'm bust looking for a 1A supply...
I have TWO AC-10Xs, and am using it with the Ninphetamene kernel (which comes with increased charge input mods to 800ma) fine. Charges to full in about 2.5-3 hours.
I've never gotten overcharge errors either.
Hi,the usage of more powerful charger will eventually reduce lifespan of your battery. This comes from basic physics, materials and so... Higher mA means faster current, which wear the material of the capacitor - battery.
I have capdase 2 USB car charger that was used for my old iphone device.
It outputs 1A.
is it safe to use it?
I tried to charge with it for 10-15minutes or so, and didnt recognize any suspicious warmups...it reached 41~degrees while at the moment im charging and using it as a hotspot and its on 38 degrees.

The phone (specifically, the kernel) limits charge coming in, and there MUST be hardware limiters on the batteries and the phone themselves (which, in some cheapo batteries DON'T WORK and results in them frying themselves and the phone in process) and the batteries are replaceable anyway.

That's good to know that the current is regulated by the device.
Is there a software to see what is the current taken by the phone?
As long ad the temperture isn't higher than 45degrees is it ok?
By the way, Im pretty sure that usb outputs 0.5A and not 1A

It seems logical to be able to use all chargers as smartphones all have micro usb .
(I 'm not sute that's mean something in english, sorry)
Great widget! thanks.
I really like the data it gives!
Sadly, while charging with my .7A original charger & meanwhile giving a hotspot to my laptop, it shows that only 76mA comes in!
hehe, gonna take forever to charge the battery this way.
i doubt this. i'm still worried about the compatible problem~~~
After two days with the battery monitor widget Im affraid itself it drains the battery.
could it be it affects the battery?
settings are regular, it monitors changes every 60seconds
Let's see if I can help make things a bit clearer. Feel free to correct where I may be off.
The Nokia thing, it's not a charger. It's a power supply.
The "charger" is built into your phone, hardware-wise.
How can I prove it?
Take the Samsung supplied cable, plug it into your computer. You'll see that your phone is charging too. No, the cable is not a charger. Do you think your computer is a special built charger for your phone? Hardly.
The charging circuit is within the phone, and thus charging the battery when there's available power.
Ok, so we have the charger (i.e. the mobile phone), we have the battery, we need the power. Where do we get power from? The wall adapters (or computers). So what are the wall adapters? Ratings of 1000mah means that the wall adapter can provide up to 1000ma per hour.
However, your charging circuit will determine how much current to actually draw. For example, drawing 800mah for 10 min may raise the temperature to 55 degrees, so after 10 min the charging circuit drops the charging current to 500mah.
Of course, if you're using el cheapo cables, some cables may not be able to support the current draw and you may find that even with 20000000mah power supplies your phone can only draw 100mah.
The SGS2 heats up pretty easily, and it doesn't quite draw beyond 700mah. The circuit built into the phone doesn't allow it to, if i'm not wrong. If your phone is overheating while charging, you better change your case as it's going to cause your phone to overheat sooner or later.
Using a 20000000mah power supply isn't an issue, because the charging circuit within the phone will be able to draw only a certain amount.
Me, I plug my SGS2 into a 2Ah charger every night to charge, and yes it's perfectly fine. I'm only upset that after buying an expensive 2A charger, I realised that the phone is not able to draw high currents (phone even heats up to 55degree Celsius when charging).
Charging the phone on a ice pack (which lowered the phone temperature to 16 degrees while charging) didn't increase the amount of current drawn by the phone, even on a 2A power supply.
My humble advise is, stick with the stock power supply, or at most get a 1A version. No need to splash for a 2A power supply. If you really need faster charging, get a battery charging dock.

yes of course it does. It consumes a certain amount of ma per hour, doesn't it?
Personally, there's a app called watchdog, look for it, IMHO it helps to catch rouge apps better, and manage battery better.
I thought the whole idea of having a universal micro USB charging connection across most good brands was so you could use other chargers!

Well I just like the widget, which shows me also the battery temperture
I hope it doesnt takes too much
Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

I only have chargers that operate 1.8amps and higher.
As the battery is an issue the higher the amps the faster it will charge

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on

This! I only charge with a wall adapter now. I had a hard time charging it until someone here recommended this to me.
Hi all:
I just did a test on the maximum charging current of the One X using current measurement equipment, and it shows that the One X does not draw above 460mA of current while charging.
With this value, i suspect that the One X limits max charging current at 500mA, which means 3 things:
1) Using any previous generation USB charger (750mA or 850mA or 1A) is good enough. Attempting to use the iPad's charger (rated at 2A) WILL NOT get you faster charging time.
2) When using battery draining applications, the charging current may not be enough for you to both CHARGE and USE the Phone. Thus it might be a better idea to give your One X some dedicated charging time.
3) Some computer USB ports may specify 500mA of output current, but there are many times the available current is less than that. On my USB port, the charging current is only about 300mA at times. So it is better to use a dedicated charger if you have it available. Having that said, however, it is still ok to charge the One X with a USB port at 300mA, just that charging will take longer.
That's all I have to report. Useful information for all.

I've had mine charge at 780mAh+ before. 1amp HTC charger. Charge rate slows down at the last 20-30% or so. So from 70%-100% battery, charge rates normally slow to about 450mAh.

thanks a lot, i can confirm the statement above because my stock charger is broken and i'm using the ipad's one.
bye
i tried to use the charger for htc chacha and hd2..
both does not work.. red light will light up but after a while it will go off and the phone does not charge..
Charging my HOX while the phones working hard eventually (after say, 5 mins), causes the charge LED to flash green/red. I've had this twice now, once while playing a 720P HD film, and once when playing Glowball.
Both times the phone was very hot, so i'm not sure if the LED thing was to indicate that the battery was too hot to charge, or that the charger could not supply enough power to charge and power the phone at the same time.

I'm using my HD2 charger at work every day. It charges at about 400/500mA.
Original charger gives me 650/750mA (lowers at the end)

If the charger cannot cope with the discharge from the game, a pop up message actually appears. If it's blinking means it's too hot. Try not to do anything intensive the last 20-30% remaining (meaning at 70-100% battery).
Nice info thanks

Same here... I am using the Atrix 4G (US) charger, it does not charge the phone. The charger gives output of 850mA. It does charge when plugged into the laptop, but I think it will take very long that way.
*edit for posterity*
after a while (I did it when battery had charged to 20%), I could connect the Moto US charger, and it would show as "AC". It would not want to charge through it when the battery was really low (2%), but it would charge via USB in that case. Weird behavior, IMO.
USB limited to 500. AC limited to 1A.

If you want maximum speed of charging (AC charging) you need:
1A charger with shorted D+ and D- pins (eg, original HTC charger).
iPad charger probably doesn't have these pins shorted, so in this case phone will see it as USB charging (you can check it in settings->battery) and will limit charging current to 500mA. Also lot of aftermarket car chargers will work only in USB mode despite they are able to supply 1A.
Here you can find some info on USB Charging Ports (shorted D+- pins):
http://en.wikipedia.org/wiki/Universal_Serial_Bus#Charging_ports_and_accessory_charging_adapters
When charger is "USB", it will not draw more than 500mA from the charger, and usually it will not charge at all (because the current draw with screen on is higher than 500mA).
When charger is AC, it seems to draw 1000mA - but this is still too low to charge while phone is doing anything, as it will draw 700mA and charge ~250mA top.
I hope this can be tuned in kernel, because it sucks, I also hope that power source can be AC (and not battery - look in dmesg when charger is connected), because battery gets too hot when under load...

Can you post a potential list of car charger which are working at 1mA according to you?
I've only tested few devices:
Extrememac external battery for iPhone/iPad (max 2A) had pins not shorted - USB charging mode on One X (500mA).
Some cheap car adapters - max 1A (according to spec) - USB charging mode on One X.
To fox this problem you should prepare a USB extension cable or micro-usb cable with shorted D+ and D- pins and it should be recognized as AC adapter. I think that also some old HTC phone chargers might come with shorted pins in cable already, but don't know which...
What about the official HTC car charger?

Yes, that one will charge at the full rate.
There is no list of known good chargers - it's down to luck or a recommendation from someone who found one. You can be sure that any charger advertised as "iPhone, iPad or iPod" compatible will NOT charge your One X at the full rate.
I found one recently in a local petrol station shop. It was £5. I took it apart to have a look and the D+ and D- pins are correctly connected together (via a low value resistor) so it charges at the full rate.
So, I might suggest you look for the cheapest Chinese car charger you can.

Bingo. I also noticed that when I have the screen on at 100% brightness, GPS and Bluetooth on, i.e. in the car, the USB charger cannot even keep up with the battery drain.
On top of that, the battery gets really hot.
I did not have any of these issues with my SGS2, and frankly, I think it's very disappointing. One should at least be able to stay on the same battery level while doing nothing too fancy and on USB inside a car.

There are a lot of factors in the charging current. When you charge, the battery will heat up during the process, especially towards the end of the charging cycle. If you are using your phone at the same time and cause even more heat and charging may slow down to prevent overheating. Also, as mentioned prior, charging slows down as capacity is reached. 100% brightness, GPS, and Bluetooth all on has always walked the fine line of just barely keeping up on my past phones on a 500 mA USB charger. On top of that, this phone is a lot more powerful than an SGS2 and the T3 and big screen produce more heat which may be slowing your charging more.
The problem is a lot of cheap chargers that the phone thinks are USB chargers, not AC chargers, thus causing them to only charge at 500 mA. If you have a proper charger, or a properly modified charger, you should get more like 1A, assuming conditions are right.
In the past I've used Battery Monitor Widget from the Play store to show my charging current on a widget, as well as track and graph battery use, charging current, temperature, etc. Might want to give it a try if you're more interested in charging details.
Im using my htc desire charger and cable (the one that splits in two). It works fine for me but it does take a while to get a full charge. Should i use the charger and cable that came with the phone?
