Fast USB Charging on O2 XDA Mini - JAM, MDA Compact, S100 General

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

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

Full Charge or trickle?

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?

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"

yes... u r rite... itz a MICRO USB...
But it can't supply power to a USB device, so it can't be used like a PC USB port. It's only good for recharging and syncing.
so if i want to buy an additional wire, i look for a USB to MICRO USB wire right? no need to buy from HTC right?
cause i saw one usb that is smaller but it doesn't fit.. is there a MINI USB port too?
am confused

Erm yes it can,
Actually better take the device with you. Sellers here told me there is like 7 different very similar connectors. However this one should be the standard micro USB, which is supposed to be universal charger/sync cable in the future (at least in EU).
And yes, of course, there is mini USB. And there even are more versions of mini USB, for example HTC used their own.
You had better use HTC cables. HD2 is microusb, but not all microusb cables are good for HD2. Like iPhone, it takes a large charging current, and many no brand cables cannot do it. I've got a third party cable that syncs only, but if charged from the PC, the HD2 will say that the charging current is too small. Battery actually drops when I connect HD2 to PC using this cable (because my options set it that backlight is always on when HD2 is connected). Other combinations are OK:
original cable + AC plug: charging OK
original cable + PC: charging OK
third party cable + AC plug: charging OK
third party cable + PC: "insufficient charging current"
Be careful with cables- you'd be better to buy the genuine HTC version.
Many USB/MicroUSB cables are for charging only, and don't have the data pins connected. Thats OK if you just want to charge it while you are away from your main PC or power supply.
You can also buy a miniUSB/MicroUSB adapter for charging using and older miniSUB charger, but again these don't have the data pins connected.
I bought a number of 3rd party USB to microUSB cables a month ago for sync and charging (office, PC, bedside charging), so far so good... no issues (maybe I'm lucky). The OmniaII uses the same connector, so I'm using the HTC car charger to charge both.
I bought Nokia's cable (for E71,N97,etc.) and it work just fine with charging from laptop. much cheaper than HTC in here.
if you are going for the cheapo option...

N86-8megapixel cable doesnt work..
So I managed to leave my HTC cable at work (2 days after getting the Telstra HD2 in OZ) and now I am on 4-5 days leave from work and really want to tinker with my phone. I think I may end up having to go back to work to collect the HTC cable - as below... challenge to get non-HTC cable to work.
I found that my wife's N86-8megapixel nokia has a similar micro-usb cable.
When connected to the PC the phone starts charging and the PC does the "doo-doop" sound a "appears" to connect to the phone, but active sync cannot detect the phone \ sync.
I see others have had success with nokia cables - I am wondering if there is something wierd going on.

Moded my usb charger, tab will charge anywhere !

Went to local electronic store and rigged up a mod for laptop charging, it basically charges with any usb port. Time to make a few spares .
one thing in the laptop it wont transfer data but it charges with my 1 dollar cigarette charger lol
why was this needed?
(new to tablets, waiting for an HTC tablet)
The tab doesn't charge when connected to a PC.
Any tutorials on how to make and items needed?

Interesting... Why is that?
are those resistors connected on pin 2 and 3? or better yet... got diagram?
The tab needs a power source that produces 5v @ 2 amps before it will charge properly.
Mine charges fine with my laptop...I beleive it only trickle charges, alot slower then the wall plugin, but it does charge.
wow 2 amps?
USB spec is max 5v 500mAh or 500mw? (2.5w ~) ? ... confused.
USB will charge the tab. However charge time is much longer due to lower USB power output.
When I go to Menu>Settings>About Tab> Status it says it isn't charging when it is connected to my laptop and the battery icon has the lightning bolt charging symbol but has an 'x' next to it so I assumed it was telling me the truth. BTW what clock widget is that in the OP picture?

While that is the USB spec for devices that are intended to use USB for data, occasionally you run into devices that will trickle charge off a 500mA connection but require a higher amp connection, usually provided by a specific wall wart plug, to rapid charge. The iPad had a similar function/issue if I'm not mistaken.

The galaxy tab charges just fine through usb connection on a pc or laptop, if ur doesn't u have two things to check, first are u using a usb2.0 or higher port and is your device set for usb storage file transfer, u can check in settings while connected to a pc or laptop, I charge my tab almost everyday using my pc as I transfer a lot of files daily, I don't even notice a difference in charge times compared to charging via an electrical outlet.

USB 3.0 Charging

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?
Sent from my SM-N9005 using Tapatalk
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.

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?

Dash Charge Cable

How does USB cable influences charge of speed? Why DASH speed charging works with the red USB cable provided by manufacturer, but not my other USB3 cables?
Does the cable have to be some some special kind, i.e. sort of certification or whatever? I would really like to use longer (i.e. 1.5 - 2 metres) cable from my charger, but all the cables I have and tried, plugged into official charger, does not support fast charge.
Thanks for answers!

That is mostly cause of a resistance between the wires which voltage drop indicates its a cable that meets the requirements. That is the common practice for such proprietary accessories.
Maybe someone has time to measure this and/or cut his original cable and find the resistor, I need mine
I'm sure it's that method.

You can buy a third party one cheaply from ali express. They work like the proprietary ones and there's also a 1.5m option. I personally haven't found any drops in charging speed at all.
Look in the USB-A side of the cable, there is an extra pin above the 4 normal USB pins which signals dash charging.
