Shocking Battery Story..

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.

Phone charging and Satnav...is this normal?

Just been on a long run and used the satnav ( google ), and the whole time it was plugged into the cigarette lighter charger.
Despite this, the battery level was running down
Is this normal - that the battery drain using the satnav/gps is greater than the charging rate?

I used mine yesterday for about a 1/2 hr journey, was not plugged in, but batterey was down to about 30%, also seemd to use about 20mb for 15 miles, so watch your usage.

Its been discussed already, your charger is not powerful enough to charge it when using satnav, so the end result is that your charger is just slowing down the discharge. Happens when you are using 3rd party accessories.

Ah - That makes sense -- where can I get a decent one - at a decent price

I'm using the factory supplied lead and still get the same, also used to be a problem with my Touch Diamond 2 WinMo Phone, was hoping Desire would be better and it is... just... If I make sure it is fully charged before I set off I can do about 3 hours with it plugged in before it goes flat, I just keep switching it off while I know where I'm going and only switching it on when I don't! That way you can make it last until it is needed.
Another thing to check is that it is kept cool enough to charge, again, in common with my older HTC winmo phone, the Desire gets very hot while being used for GPS and this can be worse if it is in sunlight on your windscreen, sometimes this can stop it charging at all, (you can tell its in this state because the indicator light blinks alternately orange and green) I angle a vent so its blowing cold air on the phone and that seems to do the trick.
Weird thing with the Desire is that for me it shows the green charge light and battery full indicator right up till it is nearly dead... rather than showing that it is draining
I've also noticed with the Desire that even If I'm just browsing the web it drains quicker than it can charge, even using mains charger, I often get a message "the current is insufficient, please connect to AC" or something like that (when it is already plugged in)
I don't think the in car charger you use would make a big difference, the current/voltage for your cigarette lighter socket is limited by the vehicle electrics (I know mine is fused at 15 amps)
Pauly

You need a charger which supplies 1A. Most 12v cigarette lighter chargers only supply 500mA
I use this one, and plug the USB cable into the "quick charge 1A" socket

Are you using Bruts worldwide maps mod? I just installed it. I ran it for literally only 5 minutes, but my phone got really hot and the battery monitor shows the app used 10% of the charge (the phone has been unplugged for 24 hours). I have a strong suspicion that this app is faulty.

Basically most usb car chargers (even 1a rated ones) are recognised by your phone as a data connection and to protet delicate computer usb circuits will only draw 500mAh where your phone requires 950mAh.
An easy mod of either the charger or a data cable will solve the problem. Your charger MUST be able to supply up to 1a.

Thats why I use the Belkin one, it detects it as a charger only and charges at full rate when plugged into the 1A socket.

Did anyone find an answer...

Did anyone find an answer to the issue of the Desire losing battery power even while being charged in the car while using co pilot? Or any sat nav?
I'm charging via genuine HTC cables and charger etc but still the Desire loses battery power if it is using a sat nav application. So my question is, even if it were plugged into a higher powered cable and charger would the result be the same due to the heat being generated by the 1ghz processor or is there an after market charger (for the car) that will maintain the battery or even charge it when sat nav is in use? thanks for any help/suggestions

Check your charger ...
It should output 1000 mA.
There is charger that output only 500 mA, and this will give you the above problem.

Thanks gogol for this reply. My htc usb charger plug is an older one though the cable is brand new (came with the phone) so you will most likely be correct with the suggestion that my charger is only delivering 500mA. I cannot check it as it does not say on it anywhere what it delivers which seems to be the case on most of these things, they dont actually specify the charge they can deliver. Are you aware of a brand/model that will deliver a full 1000mA charge to my desire? Thanks again for any help.

[Q] Dodgy phone or dodgy car charger?

Hey guys, just wondering if anyone else had a similar problem..
Everytime I connect a car charger, it charges for a second then disconnects itself, the charger is still plugged in, and the engine is running. The red light on the charger is on too. I'm not saying this is a ROM problem or anything at all, but its the second charger I've had that does this, I don't suppose anybody knows a fix if it happens on other devices too?

Is this an official HTC charger?
I know it sounds silly, but most cheap unbranded car chargers cause all sorts of problems. It's usually that they don't short the two data pins, so that the phone thinks it's plugged into a PC. It will then only charge at half rate (500mA) in line with usb standards.
Also, the charger may not even be able to handle a 500mA output, which would suggest why your phones sees the charger, measures the output, sees it as insufficient, and stops the charging. Is there a sticker on the charger starting current output? They can still be misleading though.
An official HTC car charger (just like the mains wall charger) will have it's data pins sorted out. The phone will detect this, and switch to mains charging mode, and draw the full 1000mA. You may have noticed that your phone will charge twice as fast off a mains wall charger than it will from being plugged into a computers usb port.
Trust me I've thrown out about 3 of the cheap ones! Even charging at 500mA, your phone will still not be getting enough juice to do google maps navigation with GPS.
Hope I've helped.

It's a cheap eBay one, but I've bought from the company in the past...when I had an iPhone And it worked perfectly. The first charger had a label saying it's max was 500mA. That lasted about 20 minutes..Need it so much more recently because of my battery drain problem http://forum.xda-developers.com/showthread.php?t=996938.
I had no idea HTC sold official ones (seems I lack common sense), will give them a go, at least then I'll get a decent warranty if it doesn't work...

If its a USB charger try a different USB lead. When my Desire arrived brand new the lead would only work properly when I bent the lead round the back of the phone otherwise it would start a charge (LED would light up red, phone says charging) but the battery % would never get any higher. Bought a new official HTC lead and problem solved.

Slow Charging

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?
