HI Friends
Do you hv any software to carry out fast USB Charging option, to charge my XDA with same speed as done by AC Adapter...
I have seen that other WM2003 models has this option.... like in HP 6515..
Thanks
Manmohan
Interesting... I've got a desktop holder which has to modes: charge-only and normal sync/charge mode. I wonder wether charge-only mode "enables" fast charging or wether the AC adapter does something special...
If i'm not mistaken, the typical USB port outputs 5V of power at 500mAh (milliamp-hours). And in my case, my shipped charger outputs 5V at 1000mAh . using the supplied charger would charge my Magician twice as fast compared to the USB (explanation below). I think even USB2.0 ports still give out power at 500mAh.
The Magician's battery is rated at 1200mAh. Charging through the PC's USB port would take roughly 2.4 hours. Using the supplied charger, it would take 1.2 hours. Simple equation for charging is, battery rating (mAh) divided by charger rating [so that's 1200mAh/500mAh for USB]. Disregard the voltage for now unless you plan to make your own standard/portable charger. Rule of thumb, refrain charging the battery with a higher mAh rated charger.. It will damage the battery in the long run.
Hope this helps. Cheers!
Although if you could somehow control charging via software that'd be a nifty tool...
i doubt it since max current USB can provide is 500mah as any more would damage the port and probably the board.
Hello
Yup, jedhonx your right! Its the amount of power supplied! There is no way that you could use a software to charge the device in USB at faster rates.
The only way it could be thought of is like, if your device processor is running at certain spped, it consumes some power. When it runs at lower speed, it consumes lesser power and so if the software could make your processor run low or to shut down other programs maybe would show you an incresed speed of charging!

One of the following three thing WILL happen if ALL of them...
1-Fried Motherboard
2-Fried Battery
3-Fried Device
The first can happen because the USB ports will send energy to each other, the other two because voltage WILL duplicate... Think like this, when you have a device that uses "normal" batteries like a remote or a portable cd-player that uses two or more 1.5V batteries they use it because the device works with 3V (2*1.5V batteries)... Hope I made myself clear, because my english is quite rusty...

Well if you link USB ports to increase voltage it's true that it'll probably kill the mb. But linking 2 UBS connectors to increase amps is no problem and often done. You end up getting 5V 1A output. You could even link more ports to further increase the maximum supplied amps, alltough I never tested more than 3.
Linking 2 ports in a way that increases amps will NOT fry the mb, will NOT fry the battery and will NOT fry the device.
I'd say give it a try and see if it charges quicker.
Actually I think it depends on how many separate USB chips are connected to the USB ports. On one chip (or better say channel) can be more than one port be connected on the computer (like with a passive hub). In that case, connecting two USB cables in parallel doesn't change anything. Otherwise you could connect the cables in parallel and simply get more current at the same voltage (not to mix up with setting batteries in serial).
There are USB chips on the market that supply more than the specified 500mAh, but I suppose the Magician itself detects a USB connection to the computer. I remember that the first ROMs could only be loaded by USB chargers when Pin5 was connected to Ground, which was never necessary when a real USB connection was established to the computer. USB connections to the computer only use 4 Pins. This tells me that the Magician distinguishes between a connection to the charger and a connection via PC USB and limits the power drain correspondingly. If that is the case, connecting a cable with two USB ports doesn't help, it's still recognized as PC USB connection by the Magician.
it maybe OOT, but still relates. my magician can only be charged by usb cables. wont work on ac adapter. it has been going for few months and it really bugging me since it takes 4 hours to charge through usb cables.
i did try hard reset and no change .
HI Friends
I appreciate that you are trying all your mind to find the solution..
I believe that O2 provied AC Adapter wont pass additional current to screw up the battery life as it is provided by O2 Manufacturer itself. If Adapter takes 2 Hrs to completely charge the O2 Mini, then this can be done by USB cable also.
Also if you see in any other PDA running windows mobile 5 you will see an option of "fast USB Charging"..
It means that it can be done, but we need to find out how it can be done.
Thanks
Is there any way to see if the unit is being fast or slow charged? It seems that the HTC charger uses an extra pin on the charger to enable fast charging and that MAY be why some aftermarket chargers (wall and car) do not seem to keep up with the battery discharge when running even if their plugged into a charger with sufficiant current capability. The HTC Wall caheger is rated as a 1 Amp charger. I have other chargers that use an external USB cable to connect, both rated as 1.5Amp (1500mA) chargers but seem to charge very slow. Soooooo I'm looking for the difference between the HTC charger and the aftemarket ones to see if I can make the ones I have work properly.
Thanks for any help

<edit> in Looking at the Mini USB spec I find 5 pins labeled 1-2-3-x-4 with 1being VCC (5v), 2 & 3 being Data + & - and 4 being Gnd. Does the Advantage use the X pin to enable fast charging? How? Does it provide a second 5v line to cause/enable the Advantage to fastcharge? I think I need to look at the wall charger mini USB pinouts.
After talking to Pocket PC Techs and looking around online, it looks like the x-pin (next to pin 4(gnd)) is shorted to pin 4 to provide the advantage with a sense line to tell it to fast charge. The also shuts off the data lines in the unit AFAICT. Still don't know what the current capability of "Fast Charge" is or how to ask the unit to query the port for status. USB ports are generaly limited to 500ma and the stock charger is 1000ma (1A) so it seems that to ensure the MAX charge, the cable connected needs to have the x pin and pin 4 shorted. This is usefull if you are NOT wanting to do a data transfer (car GPS, stand alone charging, etc).
Here is a link to the connector http://pinouts.ru/PDA/pda_miniusb_pinout.shtml
Anyone can add to this?
Joe
I just received the Lil Sync DUO Mini-5 Adapter from PPC tech and it works perfectly. I'm now getting a fast charge from my PC (no sync) and I'm able to charge my S705 bluetooth headset.
Interesting news on the pinouts. I've never heard of any utility that shows fast vs. slow charge.
I wonder if anyone has a utility that can sense a gnd on the x pin (next to gnd) of the input connector. Does anyone have a schematic of the advantage side of the input power/data connector. It would me that there might be a pullup on that line sothe unit see's it as a high untill pulled low by a ground applied tothe x pin.
here you have "hot to do it"

Hi,
I saw while using Tbattery 0.56 that when I plug the original AC charger that the S/W (Kaiser) detects it and therefore he pulls more current from the charger.
When I use USB cable, its detects "USB" and takes less current.
now for my question, I have a AC charger from Parrot and when I'm connecting it the device acknowledge it as a "USB" not "AC charger".
Does anyone know if there is an Hardware pin in the mini USB that notify the kaiser wether its USB or AC charger ?
Regards
Nir
Hi Nir
I don't have a Kaiser, but on my prophet I've had quite the same problem.
The USB / AC difference is about the current...
On my USB charger (able to charge any USB device), the current is 0.5A
On my AC charger, provided with my prophet, the current is 1A.
As a result, when my battery is completely drained, i'm unable to charge the device via a simple USB charger. I've got to give a kickstart using the AC charger.
Hope this helps.
David
I have diamond. same 'problem' (or more of a protection from current overdraw) here.
Actually the original ac adaptor shorted the USB data+ and data-
So you'll have to modify your 3rd party USB charger by connecting the center 2 pin of usb jack. you shouldnt do this on pc or laptop as this will render usb connection useless if it doesnt fry your devices.
Do it on your own risk!!
ohms law state
amp == volt / resistence
usb is spc'd volt == 5
max amp == 0.5
AC have a much higher max amp limit then usb
so the internet resistence of the pda set the pace
and it can it seems draw a lot more then usb is spc'd to
so it's not something the device actively does it just
try to draw as many amps as it's spc'd to
resulting in ac charger charging faster then usb
My Defy is extremely picky when it comes to charging.
I tried a few different power adapters. All run at the standard 5V used by all USB ports. The only variable is the current.
The power adapter shipped with my Defy spits out 850 mA and apparently my phone doesn't like to eat any other current. With a 500 mA adapter my Defy won't charge at all. That's strange, because it charges fine when connected to my computer, and those USB ports max at 500. At 1000 mA my Defy charges OK, but the screen becomes hypersensitive. Just moving my fingers within 10 cm from the screen is enough to scroll, make icons believe they're tapped, and make the phone do all kinds of random stuff. Spooky!
My other phones all charge fine at 500 mA, 800 mA (default Nokia charger current), 850 mA, and 1000 mA. They don't seem to care about the current at all. Same for my camera with a microUSB port. Any current from 500 to 1000 mA works. Only my Motorola Defy is playing difficult and insists on 850, not more and not less.
Does this mean that there's something wrong with my Defy or is this deliberate sabotage by Motorola to stop us from using competing power adapters?
Mine charges off the Motorola one, a Sony Ericsson one, a ZTE one, a cheapo Tesco one and off the PC USB ports. The output of the charger will only effect the charge time.
Right now charging mine off my Kindle a/c charger. Seems to work.
Of course the Kindle adapter works. Its output current is 850 mA, just like Motorola's own adapter.
Did anyone ever try to charge a Defy with a 500 mA or 1000 mA adapter?
It wont work with chagers which are being made for other phones
http://forum.xda-developers.com/showpost.php?p=13871623&postcount=49
800mA current
Even an 800 mA charger won't work? That sucks. Why did the phone manufacturers agree on microUSB as charger port standard?
Fortunately my cheapo 1000 mA adapter works, as long as I keep the display switched off during charging.
Hey my Old Samsung phone's charger 0.55A(4.75V) works best! charges faster than moto's charger! Bdw switching chargers isn't good for Batt life i read this sumwhere....
use moto charger!
It's the max output the charger can sustain. Just like the specification on electrical socket, fuse, cable etc. So it doesn't matter as long as it is not exceeded.
It works with SonyEricsson charger but not the one for HTCLegend
I have not experienced any problems with charging from a variety of adaptors. However I do have a couple of the portable li-on battery backs, they seem to have enough juice to recharge/power PSP and DSLite, but can't supply enough current to charge Defy or my San Francisco.
Does anyone know of any reasonably priced portable power packs that can do the job?
On my defy I've used my gf's HTC Desire charger (1A), and it was all good, no hypersensitivity. But I remember I bought a cheap no-name charger for my itouch and when I was charging it, there were similar issues you said.
i'm using my nokia E66 data cable in lieu of my motorola cable to charge my phone. no issues

I have a similar problem as you.
I think the Defy only charges with 500 mA to maybe 1000 mA. I can charge my Defy with any PC and Tablet USB ports, a Nokia AC charger and a couple of car USBs with 1A output. However, it won't charge with 2 other car USBs with 2A output. I measured the voltage of these two and they are good, at around 5.2 to 5.3V.
I was hoping to find a higher capacity car charger because I am using my Defy as car camcorder, and 1A simply cannot supply the current needed!
My defy can be charged with an htc 1A charger as well as a 500mA samsung charger. But it refuse to charge from no name cheapos.

Tried a new adapter, made by Sony Ericsson. 5.0V, 850mA, exactly the same output as Motorola's own power adapter. But the SE adapter has the same problem as the no name adapters I tried: they charge my phone, but I need to keep the screen locked 'cos the adapter makes it hypersensitive.
So it must be my phone. For some strange reason it doesn't like it when I use any other adapter than the one that came with the phone.
I wonder if its refusal to work with non-Motorola adapters is a reason to get my Defy fixed under warranty...
The problem you guys are facing is not related to the current, but to the pins used by the cable in the USB interface.
The defy will only charge if it is connected with a full USB connection.
Not all the USB cables come with all the pins, I for example have one for my Bluetooth headphones that only has power and it does not charge my defy but it does charge my hd2.
Gesendet von meinem CM7 Defy
The problem persists when I use the Motorola cable with a non-Motorola adapter.
When I use the Motorola charger adapter together with non-Motorola USB cables my phone charges OK.
So the problem has nothing to do with cables and pins.

It has to do with cables and pins.
If your cable has all the pins (normal data USB cable) but your adapter doesnt have them connected is the same thing as having a USB cable with only power pins.
Check out cables diagrams to see how them work.
There is even a hack for some HTC phones, where you actually short some pins on the cable so the phone think it is connected to a wall charger and not a USB port, allowing the phone to use more than the 500 mah the USB can provide (useful for car adapters).
This is fact, I'm not pulling it out of anywhere hehe
I charge both my Defy and the HD2 with the same HTC charger, and I have a extra USB portable battery, which charges the HTC but it doesnt charge the Defy, both are running CM7.... the issue? the danged chinese battery only has power pins and the phone refuses to charge from it @[email protected] it does charge my Bluetooth Headphones and the Camera
My non-Moto 1000 mA and 850 mA adapters make my screen go wild, but they charge my Motorola Defy.
If it was a cable/pin issue they wouldn't charge my phone at all.
If I plug my knockoff 500 mA adapter in my Nokia USB port (which is for data only, not for charging) my old Nokia pops up a "USB data connection detected" message.
Not all charger issues are due to cables and pins. Sometimes its the output voltage and current that messes things up.

I know not all issues are related to the cable and pins, but this specific issue with the Defy not charging is.
Both your chargers comply correctly with USB charging standards then.
Notice this also happens on the Droid, and shorting both Data pins allows the phone to charge. And can be read on the forums that it works too with the iPad
Anyways, here is what happens to the defy:
http://en.wikipedia.org/wiki/Universal_Serial_Bus
"There are also devices at the host end that do not support negotiation, such as battery packs that can power USB-powered devices; some provide power [...]. USB power adapters convert utility power [...] to run attached devices. Some of these devices can supply up to 1 A of current. Without negotiation, the powered USB device is unable to inquire if it is allowed to draw 100 mA, 500 mA, or 1 A."
There you go, no Data pins = Defy do not draw power, not charging.
I would like know if it charges shorting Data pins tho.
All that is required is short both Data pins with each other, doesnt matter if its on the cable or the charger.
The Note 3 is the first phone to come with USB 3.0 support, the cable and connector are up to spec.
What I'm wondering if this helps with the charging speed, as the wall charger doesn't seem to be with a USB 3.0 connector.
Does anyone have any insight to this?

The wall charger has a 2Ah power output while a pc usb 3.0 port has a maximum output of 900mAh. If you use an USB 2.0 port it's only 500mAh.
The best way to recharge the Note 3 is to use the wall charger.

From a dedicated charger the final charging current is normally determined by the PHONE + CHARGER based on how the phone "recognizes" the charger as good/bad (and what battery level you already have + how warm the battery is) and how much power the charger can provide. I believe the max that I have seen on my Note 3 was 1800 mA (which worked with both USB3 cables but also with some good USB2 cables).
From a PC the charging current is the result of a more complex negotiation, the phone can still have "the last word" but it can not go over 500 mA on USB2 or 900 mA on USB3.
Somehow related - please note that on USB3 DATA you STILL need to MANUALLY enable USB3 mode EVERY TIME YOU PLUG TO THE PC. Even if enabled the mode will be reset to USB2 in 10 minutes and lost if you remove and plug-in again. That being said on my Thinkpad I have not seen it charging over 450 mA even when on USB3 under Win7 (but the speed difference exists, so USB3 is correctly triggered).
Also please note that the life of the battery can be heavily influenced by the charging current - the smaller the charging current the more cycles the battery will last on the very long term. Also high temperatures are pretty bad for the battery. So if you are in no hurry it is always better to charge with a small USB2 current that is guaranteed to not go over 500 mA.
Maybe I wasn't clear enough, I'm wondering if the wall charger is utilizing the USB 3.0 capability, and if there's any advantage of using the USB 3 cable over a regular micro USB cable.

No, there is not. The Note 3 has a USB 3.0 port, but it is only faster for data transfer. Charging is done at 2.0 speed, not 3.0. Regardless of what you attach it to, it charges just as fast as a 2.0 device.

What if you used a USB 2.0 cable with the 2Ah AC adapter? Would it still charge in "USB 3.0" mode and not give you a message to use a USB 3.0 cable?
I have my old 1Ah car charger and when I use a USB 2.0 cable, the phone says to use the USB 3.0 cable for faster charging.
But, looking at this pinout:
http://commons.wikimedia.org/wiki/File:USB_3.0_Micro_B_plug.PNG
It seems like only the USB 2.0 section is providing the power?
It's utterly confusing. Would be nice if someone who really knows this stuff explain how it works?

What's strange is that I have a car charger that is 1.0Ah. When I use a USB 2.0 cable, the phone tells me to use a USB 3.0 cable for faster charging.
When I use a USB 3.0 cable, the message does not appear.
But I'm thinking that the car charger can only put out 1.0Ah regardless of the cable that is used?
