Faster USB charging?

Just got a new motheboard which has high output USB charging for iPhones, pads etc.
Can this work on N1 ?

Hopefully not, I dont want my nexus one to be iphone.
But as you know nexus one is using qualcomm motherboard.
But aslong cyanogen and fm transmitter is working there is no problem wiith your phone.

Dear lord what a crappy reply. Stick to disney mate.

It should, it basically just converts the USB port from .5 amps to 1 amp, like a wall charger.

lol I seriously hope this is a joke!
I agree with JCopernicus, it should definitely work.

I installed the software in the first post but it still charges very slow compared to wall outlet

Slightly OT, but I've got a USB adapter that plugs into the wall that came with my iphone and when I plug the N1 USB cable into this to charge the N1, it still charges very slowly compared to using the proper wall adapter, why is this? Does this iphone adapter restrict the voltage or something?

Generally, "charger detected" is a circuit that has USB data pins shorted together. So when the phone's USB device probes the lines and detects them shorted, it knows it's connected to a power supply.
But since USB max current spec is 500mA, the current draw is restricted - either by the phone or by the supply.
There might be some other connectivity trick that allows the phone to know it can draw x2 current from the socket and won't damage anything. Most phones probably don't limit the current draw and count on the board to do it. Some boards don't limit the current output, or limit it higher. And the fast chargers provide pulsing voltage - which isn't like USB.
So for the board to be able to charge the device, it needs to detect a device that can use pulsing voltage, and enable such voltage on the socket. It doesn't detect Nexus as such a device, I believe, and that's why the charging is slow.

Faster charging with USB
Building on Jack_R1's response, I believe that the phone is limiting the charge rate. You can make the phone "realize" it is connected to a charger rather than a data connection by shorting the 2 middle USB pins together. I have done this in several car chargers, and the N1 About/Status shows charging (AC), which is the faster charge mode. While you can short the pins in the larger end of a dedicated USB cable, if you can disassemble the connector, I found it much easier to open the charger itself to short the pins.

i also have a gigabyte mobo that has this feature but i havent gotten around to test it out yet. I dont think it would work because the feature is software based and will only bump up the voltage if the program detects an iphone connecting to your computer. Gigabyte doesnt want to be liable if they bump up voltage on every device you plug in and fry something.
btw I have tried charging my n1 from my computer and its extremely slow. started charging at around 5pm on sunday and at 11pm it went from about 23%-97% lol.

Yes, USB charging is very slow. It's actually good for the battery, though.

Maybe someone with some know how can look at the driver files for this 3x tech and see how it checks if its an Apple device. Then fool the check and presto!
Shame I don't know how to do any of this

There is a simple hardware (don't worry, it's on the cable) mod for faster charging; however, make sure the phone has good air vent (it means NO CASE when charging).
1. modify your microUSB cable, disconnect the data connector the A (host) plug, then shorten the data connector to the B plug. (This can charge N900 properly, and speed up n1 charging).
2. modify your powered (with AC adapter plugged) USB hub. Simply shorten the #2 and 3 connectors on USB jack. Make sure you cut the copper strip going to the chip or malfunction may occur.
These modification can greatly speed up the charging, but phone will produce a lot of heat (that's why you must have the phone "naked").

I don't understand this. If the phone + battery are capable of being charged at 1000 mAh from the wall charger then why need extra cooling when asking for 1000 mAh from a PC USB socket?
Mine's still defo getting only 500 mAh from the PC USB despite it being able to give up to 2700 mAh for iPad!!! All I want is my 100 mAh charge.

Because what he suggests isn't a proper charging but rather removal of slot power control, and will damage the battery / phone, if succeeds.
Proper charging at 1000mAh requires pulsing voltage - his hack doesn't provide that. Your MB does, but it requires SW intervention to turn it on.

So can someone brew the intervention ?

They are not doing anything to the voltage, simply allowing more current to pass.
And as said in this thread, any typical data USB cable will charge very slowly. And most standard USB ports charge well less than the max specced 500mAh, in fact my subnote at work I found charged my old phone at around 150mah one time when I was dead and needed to top off and it's all I had available.

i'm not sure of the pinout on the micro USB port but i'm pretty sure that that the Mini USB-B port that was used on phones like the G1 used shorting the -Data pin to the unused 5th pin (actually pin 4 on the connector pinout) to activate AC charge mode. some devices actually require a resister of a certain value to be placed across them to work(i know older motorola phones did like IDEN's)
one thing people often forget but should not forget is that current is drawn from the device using power. its not forced on the device. voltage is forced on a device and while a variance is usually ok for devices depending on how they were designed generally its not a good idea to exceed +1.5v on any low power DC device. 120V AC devices are designed to actually work in a much wider range like 100-130V but thats because of the power supply/nature of AC power. it always varies and in japan they use 100v 60hz AC so many electronics power supplies are designed to work in the full range to save costs and only have to make 1 unit for all (same deal with 220-240 switches on PC power supplies)
the reason why you don't want to do this mod is you could damage you PC's motherboard by pulling too much current from its circuits. USB spec is 500ma. performing this type of mod on a power adapter (car or AC) that does not get recognized as an AC charger by the phone is a safer way to go. worst case senario is you break the charger (unless you mess up on the pinout then you could damage you phone too though)

[Q] Charging Craziness

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.

Impossible to charge sg2 in car

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..
Sent from my GT-I9100 using XDA App

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.

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.

[Q] original cable not charging fast enough

I just realized my original cable doesn't charge my phone fast enough and I drain battery while using it. I swapped for a Motorola micro usb, and it works.
I downloaded an app to show mA rate, and with original cable it goes at about 360 or 450 mA. When I use Motorola cable it goes to 1900mA and proceeds to raise battery %.
What can cause this? The plug looked little dusty, I stuck a twist tie in and out (like on bread bad) and tried to clean it, but there's no difference.
Also there's no pin 4 on my cable, the ID pin I think. That seemed to be common for Samsung, so guys, what do you think caused cable to go bad, or am I missing something?
Also I use BlackBerry charger it says 800mA, this will charge it.
Thank you.

Could have just gone bad. Batteries go and all the time. I just had o swap out my sisters amdnmine for new ones because they wouldn't hold a charge for more than 6-7 hours. So its possible you just had a faulty one. Btw the phone is meantnto charge slowly. The faster your battery charges usually means the battery is giving out. But in your case you found out it was the data cable.

Could u tell me which app you used to show mA charge rate.

Its your wall mount. Try plugging the original USB into the moto box. It should charge fine. If not try the obvious (original box to moto USB)
Happened to me on my s3 and my s4. Sucks.. i know..

No pretty sure it's the cable. Used cable on 2A nexus charger, and it only did 300 mA.. I wonder where I can buy a good 4 or 5 foot usb cable for not too much money? The default usb cable length (3ft) is usually too short to reach the outlet for me. =(

I just googled this.. cheap 6ft samsung micro usb.. great prices from local places like walmart and amazon.
Although you might wanna add 2000mah. Lol

300Ma means your USB cable has no Power wire and you are just getting power from Data wires
460Ma is what you would get from a Data USB port
1A is what you get with a good USB cable and Charging Data port
1.2-1.9A is what you get with a good USB cable and Wall/car charger that can provide 2.1A.
good USB cable= 2core for power with 24AWG wire size and 2 Data wires at 28AWG.
Not longer than 6feet

Weird charging issue...

Hand my Nexus 6P three days now. Everything has been fine until this after noon.
Came home and put it on it's stock charger took it off a few hours later and noticed it was at 78%. I put it back on the charger and say it was not taking a charge. Here is where it get strange. The phone will charge off other chargers and the Nexus Charger will charge my LG G5 but the Nexus xharger and the Nexus will not work together.
Don't know if this matters, but I have noticed that the USB-C port of the Nexus 6P is a bit tighter than that of the G5.Don't think that should effect anything, but thought I'd mention it.
As i just got it I'm considering taking it back to Best Buy, but it's the 128gb model and I'd have to wait for a replacement.
Any ideas or should I just exchange it.

OK, this is a new one...
I rebooted the device and it seem to be charging with the stock charger again.
I'll have to keep my eye on this.

In the past I've noticed charging issues (on the 6p or previous android devices) can be caused by a dirty usb port (sometimes it's even caused my phone to restart over and over). I *carefully* used a bent paperclip and a *small* piece of cotton soaked in rubbing alcohol (I used ripped the end of a toothpick) to clean out the port. I got a decent amount of gunk out of it. (Caution though, I've also broken several ports and had to send for an asurion replacements when I wasn't extremely careful while pressing down on the middle tab/contacts of the usb port.)

Hummm.... I might just use compressed air every so often to try and keep things out of the USB port. Don't wanna be sticking things in there that might break it.
But the phone is just a few days old so I don't thin that was my issue.

I have a new Nexus 6P, and mine seems very finicky when charging over USB using a Benson Leong approved Type C-to-A connector. In fact, I end up losing a charge quite rapidly sometimes, as if my Nexus is trying to charge my desktop computer (i.e. "power supply" mode), even though it's in USB charge mode. However, it will work fine on a wall charger. I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU with all the fancy safeties and ripple suppression. Any idea what it could be? I think it might be a software bug.

First, just use the wall charger.
"I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU"
you are very wrong with that statement!
Depending on the trype of USB you computer has it will only supply a fraction of the power your charger will. USB 2.0 will max out at 500mA (.5A) USB 3.0 will max out at about 900mA. Many of the ports on you PC will supply even less power, usually one one port will actually supply the the full power of the USB standard. The PSU on you computer has nothing to do with it.
It is generally recognized that that using a computer to charge you phone is very slow and only if you have no other option, and even then you have to plug it into the main port to make sure it has enough power to charge (slowly) you device. Unless you lucky enough to have a new computer with USB 3.1 type-C that can deliver up to 3A, stay away from charging from you computer.
I just tested on four on my computers USB ports on my computer and only one gave me a little over 1A and that almost 1/3 of what the Nexus wall charger can do.

My 6p did this after I used a cheap usb a-c cable off eBay to charge my device in the car, after a reboot and a replacement a-c cable (belkin this time) I've never had issues again. Like you I only had issue with the original nexus charger when I went to use it at night, other chargers were fine, and a reboot did solve the issue.

You're very wrong in your interpenetration of my statement. The low amperage is precisely what I want. If I'm in a hurry, I'll use the rapid wall charger, otherwise I charge my phone overnight; it's habbit and convieniet for me since I have a small room and sleep next to my computer. The slower charge puts less wear on battery and it doesn't trickle as long either. There is also a redundancy of protections - the surge and overvoltage protection of the motherboard, from the PSU itself (including ripple/noise suppression) and then there is the surge protector the computer itself is plugged into - there isn't any safer or cleaner power in the house for charging my phone.
