I have a 3rd party micro usb cable, it's 6 ft. For the most part it works good except in 2 apps, namely Bad Piggies HD and Modern Combat 3, when I play them while plugged in with this cable I slowly start to lose battery. Like after playing for 10 or perhaps 15 minutes, the battery drains a few percent, but it has been "charging" the whole time.
When I realized this on MC3, I tried plugging in the [short] Asus Micro USB cable, and it no longer drained any battery.
So my question is, are these 3rd party cables just cheap, and can't transmit the 2A over the +/- 5V wires? Is it transmitting something like 1.x amps, and that's why the battery will slowly drain?
Next, what about extension cables? I bought a 6 foot USB 3.0 extension back when I had an Asus Transformer because that short was terribly short. [I got 3.0 because the charger needs the extra 3.0 pins because the transformer grounds a certain pin, and it knows to give it 12V instead of 5V]
When I used my 3.0 extension cable + Asus micro cable, it didn't seem to drop any battery so I'm assuming that the 3.0 cable worked because of the better quality wires.
The problem though is that the 3.0 cable is extremely fat, maybe it's just the cable I bought, or maybe USB 3.0 are just fatter than 2.0? I sure hope not..
But the extra fatness weighs the cord down, so that it's heavier, and I don't want the heavier cord.
I want to be able to use a usb 2.0 extension cable, because I need an extension cord because I want to enable OTG + charging with a micro usb OTG and a USB Y cable, but a standard Y cable is not long enough so that I need a extension cord, but the 3.0 extension I have now is fat [and thus heavier].
So the bottom line: Can I use a 2.0 extension cable to correctly deliver 2A to my N7 to charge correctly?
And if it can, is it only specific brands [name brand cables?] or did I just get bad luck with the 2.0 extension cord I have now [that slowly loses battery while "charging" and using demanding apps]? Or was it too long? I think it also is 6 feet.. I almost need the 6 feet, because 3 feet is usually too short.
Thanks!

Do the phones charge faster plug into the wall then plug into a usb port on a computer?
Yes. The wall charger outputs more amps than the usb port on your pc.
Im not sure but my phones been charging slower than before. i was running damage control 2.05 and charging was quick. But with Fresh 2.0d i feel like it charges slower. anybody else? or just me.

I sort of feel this too, especially charging on the USB port. It seems to take hours to get a green LED.
your computer, and most aftermarket chargers, have usb ports with 500 mA power. The USB charger that came with the phone, and most iphone usb chargers, are 1A (or 1000mA)
I've been thinking, and I don't know for sure if it will work, but sounds good in theory, if you could splice in another usb end on the power +/- 5V only (outer wires I think?), and plug it into another usb port that is not shared with the other one, to double the amperage. After all, it would be wired in parallel then... just not completely sure if it would fry the computer but I don't think so
winmo has a fastcharge hack that i would love.
it charges through usb at the same speed as the wall.

Wish I could find my stock charger.
Fresh 2.0d definitely charges slower via the wall wart. I noticed this right off the bat. Don't know why.
I was always wondering how to speed up this unacceptably slow USB charging (If you are in a low signal area with bluetooth ON then the battery is drained far more quicker than the laptop can charge it ending up with a flat battery ). Finally I tested the output from the pins of the wall charger and my Laptop. Even when the laptop is powered off (no data exchange) the USB charging is very slow. The HD seems to send a ~1v pulse through D+ channel when to connect it to USB port (even when powered off the device seems to check if it is a USB data port), but with the charger it does not!, so we need to break this communication.
So I put a thin plastic film over the D+ and D- terminals of the USB cable and voila the device charges much faster..(slightly slower than wall charger - 25% slower, can be accounted for by the lower power output of the laptop USB port, the voltage of laptop usb port is 150-200 mV lower).
While I am typing this my HD has gained 9% charge with screen on!! . Natively it charged atmost 1% by this time with screen off.
Now I am looking for a permanent mod for my spare USB cable hacking off the data lines.
For those in a hurry with nothing but a HD with flat battery USB cable and a computer at hand, worthwhile using a thin paper over the inner two pins of the USB cable on PC side and plugging it in. (You do this at your own risk).
Hope it helps others too. Let me know your experiences.
With my Desktop USB port, charge rate is better than wall charger if you block the data pins. The port seems to be capable of 1.5 amp at 4.96 v
Also ensure that the USB cable snugly fits the mini USB port on HD.
Could this be also the problem why (my) Blackstone doesn't receive a TMC-signal with HyperGPS & iGO8 while charging in my car?
It's a genuine car charger from HTC, so I should say these pins are already "shut" from connection, or am I wrong?
I have a usb cable that is dedicatet for charging. It dosent have D+/- wires. With this cable on my laptop the charge time form about 20% is more than half of regular USD cable..
The cable was supplied with a car BT handsfree.
Regarding the TMC issue Im not shure, Try asking the guys that developed HyperGPS they might know, if not they might be able to fix if they arent aware of the issue
Interesting tip, thanks... I've lost my charger and have been finding it a pain to charge it using the USB port on my laptop.
I cut a small strip of paper from one end of a sticky note, and stuck the adhesive end to the outer flat surface of the USB plug to secure the strip in place. Seems to have done the trick, because the charging light is on and the PC hasn't detected the device. As for how long it takes to charge... will have to wait and see.
Also, I was wondering if there was any difference in charging speed (i.e. when charging via USB normally without using this trick) between activesync and file transfer mode?
I recently bought a custom 2 amp charger after the stock one died. Anyways, whenever I plug it in, I noticed that it would ask me whether I wanted to access the USB storage. Apps that need the SD card similarly, would terminate (ex: music).
Is there any way to solve this and to make the phone realize that this is a power outlet charger and not a USB charger? I think that the Epic drew about 650 milliamps or so charging and much smaller over PC (I think about 350 to 400 ish IIRC). It seems to currently only be charging at PC USB speeds as well and not the same rate as the stock charger.
Thanks in advance.
There's a way for the phone to tell if it's connected to a PC or AC adapter depending on a resistor shorting out two pins. Make sure you don't have anything other than the +5V and Ground connected.
I had the same thing happen with a car charger. Bridging / shorting the data pins causes the Epic to see the charger as a regular charger, and not usb for data or charging. This can also be done in the cable, itself, however, then you have the problem of having to cut part of your USB cable and re-tape or heat-shrink tube it.
There's a couple threads discussing similar problems/solutions:

So its been a while since my s4 i9500 wall charger's cable been cut. Although the phone does get charged up. It isnt charging up quickly as it used to before the wire was cut. Sometimes the phone doesnt even charge even thought the battery icon shows that it is charging.
Now, I have been thinking of replacing the charger. But do i have to buy the charger or should i just replace the cables? I have a lot of micro usb cables . Can i use them with the adapter to charge up my phone?
You can use quite literally any micro-usb 2.0 cable and any usb charger to charge it; however, to achieve the maxium charging speed (1900mah) you will need a high quality shielded micro-usb cable (like the stock Samsung cable) and a 2A (or higher) usb charger (like the stock Samsung charger or an iPad charger).
Hi all,
Have a couple of the dash chargers but only one cable, I've got a tonne of other USB C cables, but anything but the dash cable will only charge slowly, not even normal charging?
Can buy more but seems like a waste.
Is there any risk to using the non dash cables.
Is there a way to force dash charge?
No guesses please, if someone actually knows about this stuff I'd like to hear from you.
Thanks.

My phone still charges normally on a third party USB C cable. There is no risk of damage with normal USB C cables, but I'd go with well reviewed cables and not just any third party solution.
No, you can't force dash charge. Only the provided cable dash charges.

Just odd that it always says charging slowly. Even when it's just the cable that's been changed.. Bit crap.
Kernels used to be able to allow quicker charging over USB, might be possible to get more out of the standard non dash cables.

Unfortunately, the USB C on this phone doesn't support USB PD (Power Delivery), so it won't charge faster on the normal cable. I find that strange, since the 2 year old Nexus 5X and 6P had USB PD.
I use a non oneplus usb c charger at bed time and it charges at normal speed since launch and I have had no problems. The only thing that makes it show up charging slowly is if I plug it into my computer. From what I recall the Dash Charge cables have extra pins in them at normal usb to C cables do not.

Apple Mac chargers x2 of them charge slowly, HP elite X2, few others, namely slightly aged Samsung ones, can't think of any that charge normally, different cables.
Even the original dash charger with a different cable charges slowly.
