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...

Always best as you know that it'll work...
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 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.

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.
Hi guys
Im having a weird problem with the battery. It seems battery doesnt charge when im using the phone although it says and shows it charging! It just stays at the same battery percentage it doesnt charge or drain! When i turn off the screen it charges the battery just fine. I called o2 UK where i bought the phone, the rep said when i use the phone it consumes more power than it gets. Can this be true?! Do you think its just a software bug or defective hardware or defective battery?
Sent from my Galaxy Nexus
This is true if you're charging from the USB on your computer. USB ports only provide 500mA. The phone seems to use more than this if you are actively using it. I recommend using a wall plug that provides at last 1 Amp (1000ma) to effectively charge the phone.
How about car chargers? Same thing happens when its charging with the car charger..
Sent from my Galaxy Nexus
If I'm not mistaken, any car charger, whether it's rated at .5A, 1A, or 2.1A is only going to provide .5A to your phone using a typical USB cable. The USB cable that came with your phone has +/- lines for power as well as 2 data lines. If you pickup a "charging only USB cable" it has the data lines shorted so that only the power lines are functional. This type of cable would allow you to take advantage of the higher current 1A and 2.1A chargers - I think anyway. I'm still new to Nexus so I haven't confirmed that, but that's the way it worked on my old phone. I did read somewhere that even with a charging only cable someone wasn't able to pull 1A from their car charger so I don't know if that was a unique issue or if the Nexus doesn't behave the same way. My understanding is the amount of current pulled from the charger is dependent on the charger AND the phone. Using a special charging cable tricks the phone into thinking it's on A/C I guess.
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.

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.
Sent from my HTC One X using xda premium
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?
My HTC 10 is about 1 year old, and I've never saw it show the "charging rapidly" message. It always charges normally, but I think that, somehow, the quickcharge thing is not engaging.
To clear my doubts, I've purchased a USB tester (model J7-t), and found out that the phone is charging at 5.08V 1.45A, with factory original charger and cable. With another charger (a regular 2.4A charger) and another cable, it charges at 5,22V 1.45A.
With phone turned off, it charges at 5,10V 0.96A.
I've tried some tips from other threads, like turning the cable over (I assume turning over the USB-C part of the cable), cleaning the USB-C port, restarting the phone, to no avail.
It has no problems connecting to the computer for data transfer, it also charges from the computer USB port.
It's running stock Oreo with stock kernel, rooted, bootloader unlocked and S-ON. As it is, takes over 90 minutes to go from below 20% to 100%.
Is this normal? Anyone knows why it's refusing to quick charge?
__________
EDIT: I suspect that the culprit is the cable itself, a HTC brand cable that came with the phone. It may not be compatible with Quick Charge technology.
I researched a bit about cables, and ordered a couple of these - https://www.aliexpress.com/item/Bli...r-Cable-1m-1-8m-Mobile-Phone/32833209044.html
BlitzWolf USB-A 3.0 to USB-C model BW-TC9. The description page says that it has a 56kΩ resistor, allows data transfers up to 5Gb/s, supports Quick Charge technologies up to 3A, and is sturdy enough to tow cars without breaking. Not that I would ever tow a car with an USB cable ...
Will update this post when the cables arrive and I test them.
__________
EDIT2: Cables have arrived, they're some fine piece of hardware. But the phone still refuses to charge at anything over ~5V and 1.45A. I've also ran another set of tests with a QC3.0 compliant car charger, to no avail - still charges at ~5V and 1.45A. I'm starting to believe that it's some problem with either the phone itself or the ROM/firmware.
I am using xiaomi quick charger and it shows 2870mah charging current at early stages of charging. Charging current was slowly decreased when battery percentage increased. is after 90% it shows below 1000mah and below. I am using ampere app from play store.
