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 am travelling at the moment overseas (for work). At home my 10.1 usually charges every night in a docking station. I bought a spare lead and my trusty multi pined (world Wide) USB charger that I use for my phone etc when I travel. When I plug the Pad into the charger it only charges at about 5% per hour so from dead flat it takes a whole day. At home its recharged in a few hours. What gives?? The charger is plenty big enough and doesn't even get warm. I tried a different charger (Not a Samsung Charger) and I get the same charge rate. Any body know if there is something special about the charger and if so how can I get around this problem in the short term.
Next time Ill just bring the Samsung charger

You need a 2 amp charger. Most normal USB chargers are only 0.5 amps.
DanielNTX is right. Our toy has a 7000mAh Battery. The normal charger provides us with 2A per hour which - by using maths - makes the tab charge from 0-100 in about 3.5 hours (slightly more as you have to calculate efficiency loss and also the tab uses power during that time (Wifi, 3G, whatever's turned on)
Phone chargers usualy only deliver 500mA (or 0.5A) per hour, some more (The Blackberry charger provides 700mA for instance). Depending on how much Amp your phone charger provides, it can take longer, in the case of a 500mA charger it takes 4 times as long. (14 hours+).
It is really hard to find a good wallcharger that provides 2A that is not either flimsy as hell or pricy. HP had a firesale a few days ago where they sold their Touchpad charger (5.3V, 2A) for a cheap 5€ (including shipping) unfortunatelly my order got cancelled due to the high demand, but you should definatelly search for a charger with a higher amperage.
Yes yoar are correct the Charger I am using although physically large is only one amp.
Looks like I am in the market for a 2 amp charger
When you are charging, is there a red cross through the battery symbol in the bottom right of the screen?
If so, then the problem is that your charger does not signal to the tab that it is a charger and so the tab will only trickle charge (as it would from a regular USB port).
The solution is:
a) to buy a tab compatible charger which sends this signal
b) buy an adapter to send the signal, search for somethig like "Samsung Galaxy Tab P1000 New PC Charging Power USB Cable Adaptor" on eBay
c) if you have electronics skills make up a little circuit to fool the tab. It involves soldering a couple of surface mount resistors between the +5, D+, D- & 0v. Several pages around on it. Here's one I found in a hurry, sorry, can't post links yet... h t t p : / / forums.webosnation.com/hp-touchpad-accessories/314741-how-get-full-power-charge-mobile-battery-car-hp-touchpad.html
I can't find my original wallcharger anymore
I use the original usb-cable and the charge unit from my SIII but it's slow as hell. And when the tab is on most of the time there is a red cross on the battery. It's very sucky
Just go find any old wallcharger that provides 2 Amps then. I bought a second original charger off of amazon for "just" 15€. It's not the cheapest I could find, but easily the one I trust most not to burst up in flames
I would recommend staying away from cheap, flimsy adapters.
http://www.amazon.de/Samsung-ETA-P10E-Reiseladegerät-inkl-USB-Kabel/dp/B0044EAVB6/ref=pd_cp_ce_1
EDIT: I suspect the SIII charger does not output 2A, really. Such a poweradapter is very uncommon for phones (I have not seen one with such an amperage yet) and only common for "high power devices".
EDIT2: If it is this one you have (http://www.amazon.de/Samsung-ETA0U8...D2LC/ref=sr_1_4?ie=UTF8&qid=1345112597&sr=8-4), then yes, this does not provide enough power for the Galaxy Tab. This has an output of only 1A.
EDIT3: For you, my belgian friend: http://www.amazon.fr/Samsung-ETA-P1...AVB6/ref=sr_1_2?ie=UTF8&qid=1345112860&sr=8-2
a bit more expensive than in germany, but you have free shipping to belgium
Buying a 2A charger won't do because the tab is limiting the current it draws from the charger unless it detects the original charger. This is to comply with the USB standard maximum current of 0.5A. If the tab drew more current from a standard charger, chances are good that the charger either shuts off due to overload or simply goes defect.
To use a 2A standard charger using the full current, you need to buy/build an adaptor cable to fool the tab into thinking it's hooked up to the original charger.

I use the original charger and I get the red cross. Damn Samsung QC...

slow charging WITH samsung charger?
I've been using the samsung wall charger from the box with my galaxy tab 10.1 and a few days ago it started to only trickle charge when plugged in with it. It charges like 3-5% per hour, and says its "discharging" in the battery menu while its plugged in. Thing is, the charger I have is frayed a bit at the male-to-tab (not male-to-block) side of the cord. Could this be causing my problem? I don't want to buy another charger for no reason, but I also don't want to send in my tab for weeks on end to find out it was the charger...any advice?
I'm looking for portable (camping/hiking type) solar charger for Samsung Note 2 (T-Mobile version). Just bought GOAL ZERO Nomad 7+ Guide-I/O Plus (which is AA/AAA battery bank. When I plugged in my Note into the solar panel instead of charging it was draining battery, so after 2 hour I wen from 35% down to 19%. I did testing on the battery bank (from USB to micro-USB on the phone and it works fine). So my question is:
1) is it possible that the panel is defective or Note2 is simply so incompatybile with the whole world ?
2) is there any other nice solar kit that would work and at the same time is small and light enough.
This is also possible because Note-2 (as well as Galaxy-3) uses 11 pin instead 5-pin USB pinout...
Eventually I would like to charge also my Samsung SLATE-7. I plugged it to the panel through the lighter outlet (as I have an extra charger that takes the power from the lighter then converts it to the higher voltage/amps - I believe is is around 19-20V). The only problem is that (as I herd) charging this way would be pretty slow. I have spent several hours last two days trying to find something that would work but after my several bad experiences with Samsung I have to be 100% sure when I order something on line. In this case I was lucky as I bought Nomad-7 at REI store so I can easily return it. I've seen several nice chargers on line today but at this moment I cannot be sure that anyone of them would work.
Any advice appreciated.
The note 2 requires at least a 1 amp output JUST to run while you're using the device (ie screen on)... It will charge slowly at 1 amp with the screen off and the phone not in use.
1.5 amps is recommended minimum to charge while you're actually using the device...
2 amps is the stock wall charger...
USB 2.0 output is only 500mA... Which is enough to trickle charge the note 2 while not in use.
So basically... look for a Solar charger that has at least 5v 1amp (if not 2amps) USB output. That should charge it. Or it my opinion? Invest in a 11,000mah + External usb battery and separate Solar panel kit. Most solar kits come with dinky 4000mah or less battery packs which is barely enough to charge your phone once. (if that)
My htc one x charger took 4-5 hours for fully charge ( its so so slow. i m a sammy user from long time. sammy phone normally tooks 2 to 2.5 hours for fully recharge battery).i feel it is even slowr then computer USB charging
Now the second part of the story. i also have Note 2 charger. when i charge my htc one x from my note 2 charger then hox tooks only 2 to 2.5 hours for full charge. i think this awkward situation is because of difference specs of chargers.
HTC Charger specs -
Model - E250
input : 100-240v ~ 200mA 50-60Hz
output - 5V 1A
made in china ( its printed on charger )
Note 2 charger specs
Model -nETA-U90IWE
Input : 150-300VAC 50-60Hz 0.35A
Output : 5.0V - 2.0A
made in china ( its printed on charger )
P.S. - i bought used (2nd hand) htc one x. Charger has HTC logo on it. So i don't know the seller gave me original htc one x charger or just any other HTC phone charger. So Can any one please match the specs of my htc one x charger with theirs. thanks
Sorry for my bad English. i hope you understand it.
Mine says made in china too. I boutgh an hox first hand but think its second hand because this came with the bootloader u locked and with w custom rom.
Anyway. Mine takes 2.5 hours for full charge while off. With the phone on it takes less time.
My charger specs:
Model TC B270
Input 100-240v 200ma 50-60hz
Output 5v

hey
I haven't chked the timing yet but the current widget shows 1000 ma while charging my note 1 nd hox shows around 650~700.also noticed that if u drain ur phone charging takes way more nd messes the batt percentage , so my advice is always reconnect when batt is under 5%
another diff I noticed is that note shows 0 ma if disconnected nd 3.6~4.18 volt usage but hox shows around 165~350 v,I was under the impression ma only shows charging
recent hox user,both on stock jb
Basic Lesson is USB power status (valid for USB 2.0)
Normal USB power will give up to 120mA at 5v to any device (HOX 1800hmA battery at 120mhA... thats 15 hours from 0%, not cool)
Now most devices that depend on USB for charging can negotiate high power mode post handshake and receive up to 550mhA at 5 volt from a PC usb port (can be capped on laptops and HTPC´s), note that this is per HUB, not per port, meaning that if you have your HOX hooked up to a PC and you have another high power device like a wifi adapter or a portable hard drive, charging will be a lot slower, that is why when using computer USB ports i recommend buying a external USB hub with a separate power supply, most PC´s have 2-3 wired USB ports which are hubbed internally and another 1-2 ports which can be activated connecting an external header.
As for usb chargers, most devices wont charge above 550mhA (3.5 hours to charge the hox from 0%) but i´ve seen devices go up to 750-800mA, i would usually recommend getting a good one, you can get a decent one off deal extreme for like 2-3 bucks, but investing in a good charger thats able to give 700-1000mA per port and also gives you peace of mind that it wont fry your devices if there's a spike is a good long term investment,
Personaly ? we had 2-3 galaxy S devices at home and i still use the charger for my HOX, 2-3 hours and its charged, and it seems they cost like 5 bucks on amazon.
This is in regarding my several week old HTC10, which I got off ebay. Phone is S-Off and running stock US unlocked firmware.
The phone is not able to negotiate quick charge with the original HTC charger.
If I use my old HTC charger (from the HTC ONE - 5V 1A) or my ipad charger (5V 2A) or my computer USB port (5V 0.5A), the phone will charge, although slowly.
If I attach the HTC 10 charger when phone is 80% or more charged (ie not really using quick charge), the HTC 10 charger will work, and phone shows "charging rapidly".
But if I use the HTC 10 charger when battery is less than 80% (presumably when the phone is asking for higher volts) I get this:
phone shows "charging on AC" for half a sec or so,
then "charging rapidly" for half a sec,
then "discharging".
This repeats every second or so, and the phone barely charges. (Certainly much slower than my 0.5A computer port.)
I suspect that the phone is having problems negotiating a charging voltage with the charger, and cycling on & off repeatedly as it tries.
I guess this is due to either a bad charger, a bad cable, or bad firmware or hardware.
I don't have other USB C cables or Quick charge 3 power brick to experiment with.
Anyone has any idea of which is likely the culprit?
This is not a deal breaker as I plan to use mostly my 1A charger to slow charge in order to preserve battery longevity. But it would be nice to figure out why quick charge is not working.
Thanks all.
Update: Borrowed a Samsung Quick Charge 2.0 adapter, and it worked with my current cable. So I guess the adapter is faulty.
