Fast USB Charging on O2 XDA Mini

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

HD2's data cable.. is it micro USB?

I can't seem to find a usb to "whatever it is" wire selling..
is it a standard micro USB port?

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...
http://shop.ebay.co.uk/?_from=R40&_trksid=m38&_nkw=MICRO+USB+SYNC%26+CHARGE+CABLE+for+HTC+HD2+HD+2+Leo+T8585
i got a couple from ebay - arrived the next day. - charge/sync fine.

charger from iPhone
The iPhone charger coud be used for charging HD2. Just plug the microUSB cord instead of iPhones and ... voila. The same outputs

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.

No AC charging

After trying a few different roms and yesterday my N7 will no longer charge when connected to an AC charger, it still works when connected to a pc.
I'm using the same charger/cable that has been working for months and the charger works with other devices.
I have tried factory reset/wipes and full reinstall. I have also tried restored backups for a few days ago which no longer work either.
Any one know why it would work from pc and not AC? Could it be a hardware problem unrelated to rom changes?

your tablet charges through PC; are you using a USB slot hooked up to a higher power connector (i know some motherboards have those)

I've worked it out. The nexus AC charger has slide on pins for countries different GPO configuration, the head i had on the charger wasn't clipped in all the way and was causing the charger to work intermittently.

lenovo miix 2 8 please help many questions- please please

Hello guys I need your kind help on the following questions
1- I bought an otg cable and found that it keeps disconnecting a lot, like when I connect a usb hard drive, or mouse, or xbox controller it keep every now and then disconnecting,
2- the sound volume is really low , especially when I play music
3- is there a software that can tell me about lenovo driver or software updates
4- when i press the power buttom to turn off the display youtube disconnects, i was wondering if i can play youtube while display is off, as I like to listen to youtube sometimes and don't care about the screen to be on
kindly please tell me in detail as I am still new to windows tablets especially drivers and software
i was wondering also is there a special forum for win8.1 tablets that is good for getting help

Mouse should be fine, but an xbox 360 controller is rated at 400mA of current draw officially and hard disks regularly peak at 500mA or more, the miix is only rated for 100mA on its USB. You need a mains powered USB hub inbetween tablet and device if you are going to use big power hungry devices like that, or one of those USB cables with split data and power connections and put the power connection to a mains adaptor or battery pack (you can buy battery packs with USB ports for charging phones).
Sound I have no idea.
Does the normal windows update facility not serve your needs? Just check back every few days.
Pressing the power button depending on power plan is putting your device to sleep or hibernate, all CPU activity is suspended in both of these modes.

I haven't seen an OTG cable with it integrated, but there is no reason why you couldnt use this with your existing OTG cable:
http://www.newtech.cat/w/en/1473-USB-2-0-Cable-Double-Power-Injector--2xAM-AH--1-2m.html
On this cable there is 1 USB socket and 2 USB plugs. The black plug is a normal USB data connection which would normally plug into a laptop or something, you would simply stick that in the OTG cable, the white plug is wired for power only, this would go into anything capable of supplying 5v in a normal USB connector whether that be one of the wall adaptors supplied for charging phones or something like this: http://www.amazon.co.uk/Digital-Additions®-Battery-Extender-Batteries/dp/B002PHC1XU

SM-T510 Tab A 2019 10.1 Otg with charge and data?

Hello guys,
Does anyone knows if there is a otg cable/hub that can power the tablet and be able to use data like usb connected at the same time?
Thanks

The 2019 tablet does not need this, since the port is USB type C albeit USB 2.0; I have connected mine to a hub and have pass-through charging and data. OTG is not really a thing any more since USB type C came about.

Can you share the type of hub you have been used?
Is the charging speed fine?

Kingston Nucleum. This tablet is in my car and the hub receives power from a 12-14v converter providing USB C PD and USB 3.0 fast charge. Ultimately, the hub defaults charging voltage to that of the lowest device connected. In my case a Sandisk SSD and a Meizu HiFi DAC Pro. This generally means that charging is slow, however it depends on your configuration. I'd say that the charging speed is fine, however it only charges when the car is running or in accessory mode and the tablet is always on in that state. As such the excess power it uses to charge whilst running is only a little more than it uses. It might charge faster if I power the hub from the USB C PD port, however I don't know if this is just pure amps or whether it negotiates higher charging voltages. I don't know if the Nucleum hub allows negotiation of higher charging voltages.

Nice, i'm using for the same purpose.
In my dash car
I'm also using MacroDroid for automation.
My issue right now is how should i leave the tablet when i turn ignition off.
I Think i will just shut it down, but i don't like to wait 30 seconds to but again when i turn it on.
What do you do in your case?

I'll have to check out MacroDroid. I'm currently set up with AutoMate, however there's a few annoyances which I think need ironing out. Vanilla Android Auto might not be the most exciting, but it's certainly the most friendly for driving safety.
I leave my tablet as-is. AutoMate automatically wakes the tablet into car mode on USB power and goes to sleep when it loses that. My car (Chrysler 300C) has accessory power for 30s (I think I can increase this in the EVIC) after the ignition is turned off which keeps the charger energised, and by extension the tablet. I'm not too bothered about having to boot up the tablet if it does discharge its battery to shutdown. I think it's maybe a week or so for it to do that, likely less when the tablet ages. As long as it charges and runs on the supply happily I think we're good. In that instance, I might have to see whether an auxiliary power bank would be a workable option. Not at this stage though. Bear in mind that most modern car head units still take about the same amount of time to boot as an Android tablet anyway.
I'm having minor USB issues myself, however this is down to the cable I need not being available. A lot of USB C "charging" cables are only pinned for power and not data. This might be part of any USB C issues you might be having. I myself need a USB C male with a tight 90° or 180° turn, out to a USB C female for the hub's pigtail. I might have to make the choice to fabricobble myself a USB cable just for this purpose....
This is a photo of the install, prior to me wrapping it in 3M brushed black steel vinyl.

I'm updating all of my comments in various threads on this. My setup with the Kingston Nucleum hubis having minor issues. The tablet still needs to be powered up before I turn on the car or at least supply power to the hub. It seems that if this is done the other way around, that is, to power on the car accessories (and hence the hub) then it seems to end up staying as the "device in charge" of the USB network. The tablet charges (slowly) but doesn't mount the USB SSD drive or the USB DAC. If the tablet is powering the hub (in charge, so to speak) then applying power to the hub via the car accessory supply has it working as expected. This does mean that the tablet ends up with a power drain when the car/USB power supply is powered down which isn't ideal. I've gotten into the habit of turning the tablet off when I park for long periods of time, however I need to boot it up to "take charge" of the USB hub network before I can start the car. It's a bit of a bummer.
I'm unsure whether this is a tablet hardware/software issue, the hub or whatever. Going into Android settings and trying to alter the default USB behaviour returns the message that it "cannot switch roles" or something along those lines. I'm beginning to think that this might be the USB hub refusing to switch/relinquish power supply roles once it has external power and hence not allowing the tablet to mount drives or see connected USB devices. It's weird behaviour, because you'd imagine that if the hub were connected to a laptop this would be a common action.

If it helps, I've read that OTG function is not included by Samsung for their device's USB ports. I've been trying to connect some together to perform file transfers with no success. However, I have been able to transfer and charge simultaneously between my SM-T510 tablet and PCs with the USB configuration set to file transfer.
