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.
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.

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.
I see that the wall charger for the Galaxy Nexus outputs 5V and 1A. Unfortunately, none of the extra chargers I'd like to use as additional chargers have this output. Some of them are 5.1V, and some of them all put out under 1A.
From what I understand, using a charger w/ a higher voltage could potentially damage the phone. I know that this unlikely considering it's only an extra .1V in my case, but I don't want to risk it.
As for the amps, I believe that using lower amps isn't dangerous, but may result in charging taking longer than normal.
Are these two assumptions correct? Also, does anyone know of any cheap chargers that put out 5V/1A? If you put in "phone charger" in Amazon, the second hit is a Samsung OEM charger that puts out 5V/0.7A, but I'd rather get one that is going to be an exact match.
700-800mah are fine and acceptable for charging. But if wanting to play games on a charger and still get some kind of charge, go with a 1000 mah charger. 1000 mah charger is also best to use while using mhl so you can hopefully not lose battery charge while streaming video over hdmi.

Haha, it's a nice charger.
If you don't get that one, do get a charger that does at least 700mA... or ideally 1A. Some of the cheaper chargers don't put out a lot of power and it will take a long time to charge your phone.

Same one.
Good question on whether it's putting out a full 1A. I guess what I do is check the charge times tomorrow with a few different 1A chargers to see if it measures up.
I use this for home:

And this for the car:
http://www.amazon.com/Griffin-Powerjolt-Dual-Universal-Micro/dp/B0042B9U8Q
Both are dual-USB and put out 1amp. Charges my GNEX and iPhone 4 (work) at the same time without issues.
Just feel like to chime in here for another question.
I know typical USB port from a PC outputs 0.5A while the wall charger outputs 1A, so besides charging time, is there any particular advantages to use wall charger over USB from PC?
I've read somewhere else states that despite the longer charging time using a USB port from a PC, it provides more thorough charges hence is better for the battery than using a wall charger, is this true?
Thanks!

I've read that the wall charger drops the battery down to 90ish % after it hits 100% and just goes between the two levels until you unplug your charger
While a USB charge is slower and charges your device up to a "fuller" charge
...I may be unfathomably wrong though

man that little Apple charger is so damn cute ... lol , ill probably end up buying it once the 1A volt charge is confirmed

I'm not an expert on the subject but I was under the impression that cycles (charge + discharge) were a bigger factor on battery life than something like this. The longer a current is running through the battery (charge or discharge) is detrimental to it's life span.
Leaving a laptop plugged in all the time ruins its battery is my source on this one. I would say it's because it has a constant charge running through the battery.

500mA is the max before the PC will disable the port. So your actually get less current.
There are some ports, depending on the motherboard that have a option of outputting more power for charging devices, and also have the port powered when the computer is off. But a normal usb 2.0 port is limited to 500mA max per spec... so a normal usb 2.0 port charging a phone is drawing less then 500mA, or it would get and over current condition and disable the port.
I design electronics and work with USB and batteries often, so let me clear some stuff up in no particular order:
- PC ports are limited to 500mA so will only ever output a max of 500mA
- You can use a wall charger that outputs 1000mA but on most devices the data pins on the micro USB need to be shorted to tell the phone it can try to draw more than 500mA. This is true for HTC devices for example. That means if you get a cheap charger that doesn't short the data pins, when you plug your standard micro-usb cable into it, it will still only charge your phone at 500mA.
- The charging controller is actually in the phone. It decides based on temperature (there's a sensor in the battery), current, voltage across the battery (current charge) and characteristics of the type of battery to figure out how much current to allow into the battery. Although its true that a 500mA charger may have different affects than 1000mA chargers, there usually is very little perceivable difference. Which is (slightly) better really depends on the charging controller and how it decides when to stop charging.
- When the battery is full, the phone continues to 'trickle charge' for a period of time. This isn't a bad thing. Overcharging a Lithium battery can be extremely dangerous, so normal charging occurs at a high speed and then slows down at a safe limit below the 'true' 100%. After that the phone continues to trickle charge to top up the battery. This is the reason you read in phone manuals you should charge the phone for 8 hours or overnight for its first charge.
- When charging at 500mA, the battery does not get as hot. This usually means you get closer to the true 100% before 'trickle charging' starts. With a 1000mA charge the battery heats up a lot more so charging may switch to trickle much sooner. Here's an example with made up figures.
Lets say you charge your battery with a 500mA charger, and it takes 2 hours. When the phone shows 100% it may actually be at 99%, and trickle charging. Leaving it for another 30 mins may take it to its full capacity.
Now, lets say you charge your battery with a 1000mA charger, and it takes 1 hour. When the phone shows 100% it may actually be at 98%, and trickle charging - It stopped sooner because the battery was hotter. Leaving it for another 30 mins may take it to full capacity.
Conclusion.. the 500mA charger took 2.5 hours, while the 1000mA charger took 1.5 hours. However if you unplugged both when the phone showed 100%, the 500mA charged battery may last longer, and so you think the 500mA somehow resulted in a more thorough charge!
At the end of the day, it doesn't matter which you use. the absolute charge cycles is what counts. Charge to 100%, then dont charge till its 0 for best battery care. Constantly plugging into a charger or dock all day on and off is bad. But having said that, your phone is there to be used, so a sensible balance of the two is the best bet.
Thank you so much for the detailed response, kam187. Would you recommend avoiding using a 5.1V charger, considering the phone came with a 5V charger?
Sent from my Galaxy Nexus using Tapatalk
I wouldn't use it. The 0.1v probably won't make any difference, but it may not be regulated. Chargers with these odd values sometimes don't have any regulator inside them. That could damage your phone as the voltage could shoot up and down as the current draw changes.
Just search amazon/ebay for any MicroUSB charger, and pick one from a reputable manufacturer like Motorola, HTC, Samsung etc. Since all phones now use MicroUSB, there's loads of these chargers around from previous phone models etc.
Here's just one I saw on amazon.com:

One of the immediate side effects will be that your phone will take a longer time to fully charge your battery.
If I helped you out in any way please thank me. Thanks.
Not sure how the blackberry chargers are. I know some of the Motorola chargers are accepted by the phone for high current charging (any charger that doesn't puts the phone in low current mode).
I charge my phone every night on my old 700mah Samsung charger and while it does take longer youd hardly notice unless you were trying to get as much charge in say an hour as possible. So as long as the phone doesn't limit it you should be good. <500mah is very noticeable.
I know it will take longer to charge. But Im not as familiar with appropriate charging output for li-ion as i am for ni-mh Sanyo eneloops for example that ideally should be charged at 220ma to maximize cell life.

The rule still applies the less current used to charge the better the lifespan. The phone was paired with a battery with the intention of using a 1 amp charger. The phone will only allow high current charging mode if it thinks the charger is Samsung. Shorting the data pins is a way to fool it and many aftermarket chargers already do this.
With your phone on and the phone in low current mode (320 mah i believe) you will have a hard time charging the phone if anything is wake locking the phone even screen off. You will even have trouble charging and using the phone at 500mah depending on whats going on.
The phone will be eating some amount of power from the charger, the battery is not always seeing as much current as you might think. I always stick by the practice of not deep discharging it, LiION would rather be topped off then not charged (geeze remember NiCad laptop batteries.... lol). I feel this battery will be the shortest lifespan of any phone or laptop I have ever had. Just due to how much use it sees.
Charger
Any micro usb charger should work. I've had a dozen or so different gadgets that all use micro usb from Blue Tooth headsets, to speakers. I use all chargers interchangeably with one noteable exception. My wife's Nook Tablet will only charge using the provided Nook charger. Found that out the hard way.
I have also found that not all micro usb cables will provide data transfer for all phones. I'm guessing different pin-outs? For instance when I was trying to root my ET4G, I forgot my OEM cable at home so I tried to use my EVO cable. That dind't work well at all.
My old blackberry chargers seemed to work fine but I started seeing some strange jumping around of the battery while using. For instance it would all of a sudden jump up to 100% charged then if I unplugged and plugged back in it would go back to 70% or whatever. I went back to only samsung or just charging off usb. I use my pc, printer, cable box etc to charge my phone.
I charge mine with either the stock charger that came with my E4GT, or an old 700MAh charger that came with my old Samsung Rant. Occasionally I use the charger that came with my HTC Evo 4G. I really can never tell a difference. Although, like someone above said, it seems as if non-Samsung usb cables will not charge when plugged into a computer. That's how it is with the HTC cable, and I've also tried an LG usb cable and got the same results.

I had the exclaim, the replacement to the rant and thats where my 700mah charger came from.
All of my other Micro USB cables except the one are non samsung and I use them all for charging, data and they charge while connected to pc. But none of them are from other phone manufacturers or anything. The Micro USB spec is what these phones are using there is no difference.
The difference that matters most of the time is tolerances. Its easy to end up with cables that will work well in one port but not another. The rest of the cable may also be out of spec and not work well or at all for certain purposes.
I've ruined two batteries because of non-OEM chargers on the ET4G. (Actually, ruined two, and made a third battery just render terrible performance.) I definitely don't have the problem with other devices I own, and it's definitely happened with two separate ET4G's I've owned.
So, "be very careful using alternate chargers" is all I would advise.

If the phone is looking to pull 1A and your charger is rated for .7A I'd be worried about the charger not the battery, which technically is a cell not a battery.
Tolerances were mentioned before and I think that is most of the problem with certain cables working fine for some people and not others. All connectors and cabling are supposed to meet the USB spec and many cheap ones don't. Also the supposed 10,000 insertion rating for micro USB is a bit optimistic imo. I replace cables after a couple months max because of loose connections.

Not really because these chargers are doing AC to DC conversion and voltage regulation is a huge factor in its job. With a bad charger design not only can charging be affected, possibly even hurt the battery. Since the phone will consumer charger power to run while on the charger the phone can become unstable. Not talking a defective charger, just bad and cheap designs.

I think about that alot actually. Coming from PC power supplies you never want to overload the unit. But I know for a fact I have devices that demand more from chargers than can be given, and do not have the low current and high current modes like this phone.
I am no electrical engineer and am only familiar with AC to DC and DC to AC circuits and various voltage regulation techiniques. But it is possible to current limit as well right? You design a half amp charger, with the data pin short to put the Samsung into high current. You limit the current to 500 mah but over build the components just a little to increase lifespan.
Anyways, I bought a 2.1 Amp RCA wall charger from walmart last night on a wim. 9 bucks, might come in handy when i get a tablet. Has a 1 Amp side and a 2.1 Amp thats shared with the 1 Amp. Phone didn't show any ill will to it and I had my Schosche GoBatt on the 1 amp end. If the phones drawing too much current could be bad in the long run but its working so far. Charged at the normal speed of the stock charger.

I agree with you on bad and cheap designs. How many tv's and other electronics have been rendered useless by a few substandard capacitors that saved the manufacturer $.02 per unit?
I try not to use any charger that doesn't have HTC, Samsung, etc on the label. I figure if they were willing to back it warranty wise for the original device it should put out clean enough power.
I'm far from being engineer but I do quite a bit of hardware hacking and learned a little bit about electronics when I was at Ft Gordon. So I'm not completely lost around a multimeter
I would imagine that there is some protection built into the charging circuit of the phone itself. How effective or what kind of tolerance Idk suppose I could look for datasheets if anybody really cares.

Hi Guys,
I have a thinkpad which has regular USB and also a fast charge USB port. They have worked fine in the past on other phones and I used to see at least 1 amp charge rates. (on the fast charge port)
Using either port on the 20 X I only get about 200 ma charging rates?
I'm using "Ampere" to get the charging rates, it is definitely charging slower than normal...
Have you guys noticed this?
Also of note, It charges really slow from my car as well. On the hour drive home the phone only went up 4%. (This is a VW using android auto)
I think all bets are off when your using 3rd party chargers. I think Huawei might have some official accessories that you may need to buy.

I have a bunch of phones and every single one of them charges at normal charging rates off my laptop and in my car, this is pretty strange...
Huawei uses a completely different setup from QC 3 from charger to cable . How does it charge with the supplied charger and cable that you received with your phone? If you buy extra chargers for home or car make sure they say they do Huawei "Supercharge". They are a little hard to find but they are out there. Make sure the USB cable is rated for 5a(amps)

I haven't even used the included charger and cable, but plugged in at the house I do see 2 amp charge rates which is great.
The downside is that in the car with android auto I can't really plug it into anything other than the car's USB and that give me a really slow trickle charge. This is where a bulk of my charging occurs since I drive for work so much. Basically I have never charged my other phones outside of the car, I just use android auto all the time and the batteries are always topped off. So not being able to charge from car or laptop is not a deal breaker at all, but it certainly means I need to start carry a charging cube around everywhere.
Just seems odd for such an expensive flagship phone to not charge correctly via USB like every other phone I have ever had.
Try the supplied charger and cable just to make sure you do not have a defective phone. When you plug in the cable to charge watch your screen. It should show your battery percentage and a short lighting bolt. Then in just a second it should change to a long lighting bolt and say super charging. If it does that you know your phone is charging correctly. Take your Huawei supplied cable and use it on your laptop and car and see if that doesn't increase your chances speeds.

I gave the original cable a shot and it still basically charges at 200-250ma from my laptop. Very odd indeed. Not even seeing the normal 500ma that you would get on a regular USB port. (Tried both standard and high charge rate USB ports on my lenovo)
Anyone else seeing this behavior?
