**** Cradle mod not working!!!
I modded my MDA cradle. Didn't work out. I think that the USB bus isn't suplying enough power. When I put the MDA in the cradle it syncs without any problem and the charging LED goes to yellow, even the power meter says "charging". Strange enough after half a day on the cradle the MDA doesn't charge. It completely depleted. So I needed the charge it using the external charger.
I rececked the connections and used my multimeter to verify the power. It does supply the 5V. But I think that the 500mA is not enough to charge the 2A beast.

charging issues
Maybe you already did this but make sure that you turn off the unit while charging. Make it turn off automatically after a few minutes. It will occasionally wake up and if it's not set to shut off it won't charge enough compared to the screen draw on power. The USB 500ma is enough it just takes longer (around 8 hours) compared to the 2amp charger ~1-2 hrs.

Well, you're right I don't turn it off. I'll try that for a change.
Thanks
Niels, also make sure that you connect the MDA cradle directly to a port on your PC/Laptop, and not via a USB hub. USB hubs are known for not being able to provide enough juice.
MDA Cradle Mod and now it is charging
Got it working now!. I remodded the craddle (yes soldered again!) I connected it to my computers' 5V circuit. No problems now. I can leave it on AND charge it.
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.
My battery usually takes about 8-9 hours to charge (from about 10%, so it's charging a little over 10% per hour). I'm using the USB cable that was in the box, and it's plugged into my laptop. Is this normal? It seems like a ridiculously long time. If I bought a wall charger and used that instead would it charge faster? Or if I used the USB cable but with a desktop instead of a laptop?
Usb will be slow its going to be the same on desktop or laptop. They just don't put out the juice. Wall charger is very fast to charge.
Should be MUCH faster with a wall charger, USB charges are usually quite slow.
EDIT: beat me to it...
Nah it's slow regardless of whether you charge it via USB or wall charger.
It's not the only phone that charges that slowly, e.g. the HTC Touch Cruise had the same issue (but not the HD and HD2).
One method to test this is to plug your phone in and use it heavily (e.g. for web surfing or GPS navigation).
Most phones will still charge the battery then, but the Desire is one of the phones that actually lose charge. It doesn't get enough charging current.
Sucks, but you can't do anything about it. It's a hardware design issue.
Well my phone charges slow as f..... through the usb connected to a computer aswell.
But it charges in like an hour or two when connected to the wallcharger.

Which, as mentioned, is normal.
Hi,
Was reading about this issue in some android-board a few days ago - just can talk for the htc desire, but there is something special in the combination of original usb-cable and original wallcharger!
Only with this combination the desire is loading with 1000mA - if you plug the desire to another wallcharger, even if this also supports 1000mA or more, or to a laptop or a pc, the desire will be loaded with only 500mA.
This would be normal for pc or laptop, as the usb-connectors don't support more - but it is strange that even on wallchargers with 1000mA or more the desire is also loaded only with 500mA!
On the desire you can check this under Settings-Telephone-Battery - if you're connected to pc, laptop or a not-original wallcharger, you can read here: Charging (USB), with the original wallcharger it reads Charging (AC)...
Alright I went to a Verizon store and bought a generic micro USB wall charger and it's A LOT faster. It seems like it takes a little over 3 hours to charge, does that seem about right?
Yeah that sounds about right really. Think mine does a full charge in roughly the same time from almost dead.
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.

Achim
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?
Friends,
Interesting observation here. For the last week of owning the SGIV phone, my battery life is awesome, however when
it comes to charging it takes *forever*. When I mean forever, I don't mean two to three hours, like almost 8-9 to get a full
charge.
11:30am est battery was at 17%. At 3:30pm est, battery at 47%. when charging.
Any ideas if its the battery or phone?
please advise,
tvos
It shouldn't take that long to charge. Mine charges with a way higher rate. So I guess it's a problem with your phone /battery
Flowed from my GT-I9505 using xda-developers app
Proly an issue with the charger - i charged slowly from a computer outlet - but a couple hours later did the wall outlet (using a motorola charger and it was juiced up in a just few hours) - Might be related to the charger and/or usb cord in use.
Make sure you are using a 2A charger like the one that came with it
I was discussing this with a friend after I posted my concern.
Apparently, if you charge by usb from a computer source, the amp is lower hence, it will take three times longer.
If charged by wall outlet it won't take long for the phone to charge quickly.
Just in a half hour I decided to test this theory and it works faster at wall outlet.
Thanks people...

Use original charger in the wall outlet. Takes 2 hrs from 1%
Sent from my SGH-M919 using xda app-developers app
not sure if this was mentioned in the FAQs and I did look.
Might want to add this in the FAQs - differences between the battery outlet charging vs. computer source.

Normal usb power is 5.1 volts at 1amp. Bigger battery chargers are normally 5.1 v but at 2amps.. that being tablet chargers and bigger battery devices.
Plugged into a comp and not into an outlet I think you get 1/2 an amp ( wayyy less then originally supplied and intended charger)
our s4 came with a 2amp charger. You can read the specs on the side of it.
if you were using a 1amp ac adapter which is what 90% of mobile phones have, then it would take significantly longer.
my battery charges in about a hour and twenty minutes using stock s4 charger and cable.
