I can't figure this phone out with regard to charging.
1) Won't charge via computer USB (I've heard the reasoning for this - still seems stupid)
2) Charging w/ 1amp 5V wall charger - phone screen is non responsive to touch, but phone charges (unplugging it unfreezes the screen)
3) 1amp accessory USB charger, won't charge the phone at all.
Are the charging limitations software or hardware based. I can't come to terms with the fact that this phone can't at least charge by USB. It doesn't need to be lightening fast, but it should at least charge.
Is there anything that can be done?
are u using OEM charger and USB cable ?
charging by USB
My phone charges with just the USB cord and a PC, It is a bit slow to charge that way, but it charges. Are you sure you are using a powered USB port?
it will charge via USB, you just need to install the motorola drivers. it needs more current than the original USB standards allowed for. USB can provide that current now, but you need the drivers.
Not OEM
None of the above are OEM chargers and the cables are no OEM either (Wouldn't think the cable has anything to do with it).
Since i am out and about a bit, i have to have a portable battery powered backup charger, i also carry a wall/car charger that is capable of doing both at the same time.
cable has nothing to do with it. The power requirements are strict for this phone, and it's all down to the proper way to charge the battery.
I know for a fact that the generic energizer car charger i picked up with interchangeable ends for different USB types works perfectly for this phone. It might be worth it to just jump on ebay and grab another OEM battery instead of trying to run around with chargers.
have you measured the output of those 1a chargers? i have an adapter from china that says 1a but only puts out 0.3a and doesnt charge my atrix either.
I am still using the chargers I had from my blackberry 8900. The bb wall charger works great. The car charger (att) with the flip cover over a usb makes my phone hot as hell but it still charges.
Think i've also found that, once you have the motorola drivers installed on your computer, disabling the data connection to the phone (as in selecting "None" for the USB connection option in the notification pane after you connect the phone) seems to allow the phone to charge a fair bit faster over USB. Kinda makes sense too when you're thinking about it... since it wouldn't be constantly accessing the phone as a storage device.
Yes some wall chargers dont work i.e. the two I had from my Nexus One, BB chargers seem to work well as I believe they needed more juice to charge in the first place, for the usb cable, the best solution to try is getting the updated usb drivers as mentioned.

I have a mini usb lead with me but not the exec charger. Can I just plug this into an IPOD or Blackberry charger and will this charge it?
I think you can without problem...
However, there is a small issue:
The usb standard specifies a maximum 500mA current for the usb supply (over 5V), but to charge the Universal in a reasonable amount of time more is necessary (The supplied one is 1A)
I succesfully charged the battery using a motorola psu, and in the same way you can charge it leaving it attached to the PC usb port.
I am pretty sure there is no risk for the phone but it is possible to overload the power supply - you better check it does not run too hot. Also, put the phone in flight mode and turn it off, to minimize the amount of total power used

Not sure which ipod charger you talking about, personally i use the original one from apple (white with the USB plug) and it wks fine. The original charger for universal also has the same current rating of 1A @ 5V so I guess it shouldn't overload it.
Yes, I charge my Universal with a BlackBerry charger from time-to-time.
Keep in mind what TheDayOfCondor said about the original charger putting out 1 amp while the BlackBerry charger is only rated for 0.5 although I haven't had any issues.
right, that's good to know. thanks.
My battery discharged while I was travelling - it went to <10% and shut off by itself. I left the original HTC microusb over seas and so I used my old Motorola microusb to try to charge the phone. After leaving it overnight a number of times I thought the battery was dead. I ordered a new battery (from Mugen) and tried to charge that.
All I get is a flashing orange/red light. The phone does not turn on.
I have tried charging on both the AC charger and via PC usb port.
Are all MicroUSB cables universal? I can't get a straight answer about this from HTC's customer support. Every time I call someone gives me a different answer which leads me to believe that they have no clue what they are talking about.
Is there anything I can do to remedy this?
The HTC AC charger is rated at 5V 1A, while my old Moto charger is rated at 5.1V 850mA. Could I get a charge by using slightly higher voltage with lower amperes?
I really would like to avoid sending it back to manufacturer warranty so if there is any other alternate route I can take please let me know.
I have some cheap MicroUSB cables and they seem to charge very slowly compared to the HTC one. There may be a difference, but I suspect the cheap cables are just plain cheap.
No the Motorola charger wont have done it any harm, 0.1volt wont make a difference, and charging at a lower current is less likely to cause damage.
Could I have damaged the phone by using a different companies' cable?
Is there a chance that the phone is FUBAR? Should I be able to turn it on if its plugged into a power source even if the battery is dead?
please excuse the bump
need to know
*bump*
I've actually tried all the different combinations of charging and they all seem to work fine
I've tried a cheap microUSB cable with the official charger, official microUSB cable with iPhone charger, cheap microUSB cable with PC, another cheap microUSB cable in my friend's car, and even a Nokia microUSB cable in all the mentioned combinations
They all just gave different current readings (from CurrentWidget) but in the end they all worked well. I'm not sure if a Motorola microUSB would have modifications that cause incompatibilities though
I also tried different Micro-USB Cables and my DHD still works normally.
me too have the same problem. I got a total of 3 diff USB cable. One give me 330mA, one give me 120mA and one gave me only 50mA. i do not mind spending the money if i know how to choose a USB cable which can give me 330mA everytime i charge. Anyone knows how to spot the correct ones?

Any Blackberry USB cable should work..
used Motorola cable many times. No issues.
Might be a fluke that u busted ur phones charging system.
The USB cables are all the same and have no effect on charging current. The charging current is determined by how the two data lines within the cable are terminated in the charging device. If the data lines are left open ciruit, the phone interprets this as being a USB charger and will therefore only draw a maximum of 500mA to prevent damage to a PC's USB port. Chargers that are capable of delivering more current (such as a wall charger) connect the two data lines together. The phone then interprets this as being a charging device which is capable of delivering a higher current and will draw greater than 500mA. If you look at "Menu - Settings - About phone - Battery" it will state either "Charging (USB)" or "Charging (AC)" depending on what you are charging from.
Got an old iPhone usb charger with a generic usb lead which charges the phone fine but when it hits 100% the alert to say it is fully charged never happens yet if I then change to the official samsung usb lead after 5 or so minutes the phone then vibrates and says it is now fully charged.
Not so much an issue as the phone charges fine just wondering if anyone else has seen this
The good news is with this 'feature' the phone doesn't wake me up when it's finished charging!
I've seen problems like this when using other generic usb chargers on other phones. I believe the wattage provided for charging can vary, which can cause issues.
I used Samsung's data cable connected to an HTC charger and the phone launched the MTP screen and tried to connect to my power outlet via USB. I haven't had a Samsung phone in years but from this I'm guessing that they're pretty sensitive when it comes to cables and chargers. I ordered OEM cables and chargers just to be safe.
I went out of town this week and made sure to grab my USB cable, but left the AC adapter at home figuring I'd just charge off my laptop via usb. Apparently not... I also tried plugging the USB cord into my iPhone AC/usb adapter with no luck. The only thing I've found is that when you turn off the Tab and connect to one of these devices, a green battery indicator will pop up showing that it is charging. Well, after about 16 hours, it made it from 15% all the way up to 48%. Does anyone know any way around turning it off to charge or why it is barely charging when it is off?

Well seeing as it has a 7000mAh battery, just about any run-of-the-mill USB charger isn't going to cut it. The amperage would have higher as well. Now i would hazard that an iPad charger (10 watts) would probably work just fine vs an iPod charger.
Your laptop's USB port isn't providing enough juice to charge fully. With the screen off it will only trickle charge and very slowly at that.
You'll need at least 5 Volt 2 Amp chargers.
You can also try this:

Or this:
http://cgi.ebay.com/190522553195?ru...ee-All-Categories&_fvi=1&_rdc=1#ht_3085wt_905
I've ordered both last week but neither have arrived yet. I'll report back.
You need a 5vdc supply that will provide 2A. 10W, not 5w as the previous post said. That adapter on ebay won't help the charge, it just disconnects the data line so it does not change its mode when connected to a computer. There are a lot of power supplies that will work and even more that won't, just made sure it supplies 2a. If you want to charge off your laptop then you will want a Y adapter similar to what is on usb powered hard drives but even then you will need to use 2 usb 2.0 or 3.0 ports and will provably only get 1a out.

Hi all, just came 3 days ago from an htc hd2, and so far I am more than happy with it.
I have only one complaint and maybe you guys will help me sharing your experience : I can't charge this phone in my car while using gps.
It seems that the power adapter is not powerful enough to charge the phone screen on.
The car charger has a 5v 1000ma output, more than the regular wall charger provided by Samsung and it was working well before with my HD2 so I have no clue about this problem.
Did you experience that issue too, else can you share what car charger do you use?
try to buy new standard car charger with micro plug.. 13 eur and you will be saved..

Charger doesn't matter unless the phone is dropping into USB charging mode - phone limits to around 600-650 mA by default.
Custom kernels can bump this limit up for I9100 users. I777 users are screwed - we've got a crippled charger chip.
I had the same problem, I used the samsung one, useless, so I used my iPad charger, which is 2A, and charges the iPad quick, still useless. We drove from Bathurst NSW, down to Melbourne, about 10 hour drive, plugged in all the way using GPS, and about an hour from home, the connect to charger warning came on!! So once I stopped GPS, it started taking charge. Looks like when the phone is in use, it draws more then it takes charge, plus I read somewhere on here the phone is limited on the charge it takes, so using the 2A does nothing different then the stock 500mA charger.
I always had this problem with my Nexus One, although they are different phones, the problem is the same, uses more power then it can recharge in USB mode.
After trying 3 or 4 different charges I remember that I found one ultra-cheap 'made in taiwan' from a street seller that worked very well.... so it's kind of a lucky shot!
good luck!
Im using a genuine Samsung SGS2 charger and I can charge and run Sygic just fine. I started my journey with 80% and 40mins later I was up to 91% when I stopped and got out. (not in aeroplane mode..)
Very interesting feedbacks... So that confirm that is clearly not a matter of output amperage power.
It is now the same problem on the galaxy tab 10.1, for quickly charge this tab you need the Samsung compatible usb adapter.
It can be likely with a tab bringing a proprietary plug, but I didn't thought it will be the same with a Samsung phone bringing a regular micro usb plug. Quite frustrating and disappointing!
I will search around a micro plug car charger as suggested by redzion, but actually I don't clearly see the difference with my usb charger + a micro usb cable.
Double post, sorry.
If I use the usb cable from my cd player I have the same problem but if I use the official Samsung car charger Ithe only problem I have is the phone getting stupid hot

Oh Samsung, when you will understand?!
Samsung DOES follow the USB charging standard - it goes to its highest current setting when a charger that follows the standard is connected.
Note that iPad/iPhone chargers do NOT follow the standard - Samsungs will treat these as USB hosts and limit to 450 mA instead of 600-650.
Modified kernels can increase both of these values on I9100s.
The only thing Samsung really did **** up is counting screen/CPU current usage against the charge current limits - that's just stupid.
So the charger has smarts. On the i9000 factory chargers, the data pins were bridged. Bridging these pins manually on a USB cable when connecting to a USB source (such as a PC) enabled full current charging. You can see this in Settings -> About; it will say either USB or AC charging.
Do you think this is the case with the i9100?
I don't condone testing this theory on your i9100. Increasing the max current via custom ROM may be a safer solution.
I had the same problem. Two things fixed it for me:
1) I bought this charger: Sony Ericsson AN300 Micro USB 10€
2) I am using a custom kernel now
Any charger that is rated at 1000mA or more (per port) will do just fine. The problem is the cable - you need a quality microUSB cable, or it won't provide all the juice you need. I had the same issue, and I swapped three chargers until I found the real culprit.
Try with the charger you have now and the mUSB cable that was in the phone box - it should work well with that one.
I just press the power button to turn the screen off. when i need the sat nav i press the power and it still tracks you so there is no delay. With the screen off it does charge.
same problem

You are right, but even if it is better than nothing the charging time is still a big problem.
Yesterday I drove for at least 40mn phone off. Arrived to destination, I turn the device on: it charged only from 0 to 5%
I would like to test the mariusi theory concerning the Samsung micro usb cable, unfortunately on my SgsII box I just have a wall charger, no a microusb-usb cable.

Is there a way to know before buying if the charger respect this charging standard?
I have some cheap usb chargers here and no one is a fast as the one provided by Samsung.

Maybe for safety purpose? Gps phones can become very hot behind the car glass.
Samsung are trying to "encourage" you to buy only their official accessories. To do this they've wired something differently in their chargers and cables. This "problem" exists on the Galaxy Tab too and can be solved with this adapter...

It's cheap and turns a trickle charge into a full charge. I don't know the specifics of what they've done, but their USB charging just isn't the same as most others manufacturers.

Great find.
Pretty sure it just bridges the data pins.
