******Sorry.. Should Have Posted This In Question & Answer Section*******
Hey guys.
I was wondering if their is a kernel that support USB Fast Charging.
I have a Pioneer AppRadio which connects via MHL to mirror my phone to the radio in the car.
The phone loses a great amount of battery through this even though the MHL is powered.
However the phone sees the MHL as a USB charging device and therefore limits charging to 500ma which sucks.
Other phones have kernel support for USB fast charging and they can charge at the rate of 1000ma - 2000ma so that they can charge the phone and use MHL.
Someone please help me solve this problem.
Thanks! :laugh:

Their is not.
SpeedMod charges faster than the stock kernel.
Actually NX kernel supports that.
I do not beleive it supports mhl though.
And its for cm 10.1

Not sure if there was fast charge in NX tweaks app. Just to control the current..
It is possible to charge faster, but I prever not too, It produces more heat and can damage your device.
NX-Kernel by Neo allows you to do that.
I think this only works with the 230V/115V charger, computers can't charge faster than 500mA, USB 2.0 doesn't allow you to charge with a higher current.
Thanks for the replies..
So why is it that other phones have Fast Charge kernels but the Note does not (okay only 1 CM kernel) ?
Can any devs support this?

Note is doomed from the very beginning...
So let's make this very clear. The Galaxy Note can (and will) use more power than it can ever draw from the charger ?
Doesn't the official charger somehow trick the device into using the full 1 Amp of current instead of the half amp ?

I must be doing something wrong, but can't figure out what
I wanted to enable fast charge, cause my device drains more battery than it charges, I installed the "fast charge" app from the play store, but it always says my kernel is unsupported.
I've already tried these kernels:
-franco (franco kernel updater)
-fugumod (fugumod updater)
-trinity (trinity kernel toolkit)
-faux (fauxClock)
-timur
and I've searched in each app for a place to switch it on but couldn't find it anywhere.
I'm running cyanogenmod 10.1
the tablet is rooted and unlocked.
anyone any idea what could be the problem?
thanks for your time!
Give NCX Kernel a go, I'm nearly 100% sure (99.9999%) that has fastcharge enabled.

so far, I've been unable to find a zip with that NCX kernel, so I could flash it, can you provide me with a link or something?
I only find .img files, and I'm unsure what I have to do with them :s
Don't waste your time. If you tread the reviews, your problem is common with that app. Download Trickster Mod and use that asp.
Also, fast charge isn't going to have any effect if you're plugged into an ac outlet.

Like najaboy said, fast charge has no effect using an ac charger. Only speeds up charging if your charging via USB.

Does fast charge via USB even exist for the nexus 7, because so far this seems like some sort of vapourware joke that doesn't exist.
My device is shot, the headphone jack has gone bad, and now regardless of what I do I will always get charging from USB. It won't connect to the PC, and won't power devices from an otg cable, I even made a fast charge usb cable that tricks the device into thinking its an ac power source..... It works with everything but this, so its safe to assume that if indeed there is no fast charge I will take great pleasure in smashing this to bits.
Has to be up there with the first generation Xbox 360 as one of the worst build quality devices ever made.

And even then only if the active USB device (e.g. powered hub) is also designed to not current clamp or fault-open at currents above 500 mA. It takes two to tango.
Even when it does work, it's nowhere near as fast as a 2A AC adapter, btw.
USB 3 can output 900mA

Any change to resolve this issue?
I have a 2A usb car charger, but is I use GPS programs (like waze) , battery drain in too high , and charging current is not enough.
Any Fast Charge supporting kernel could be the solution.
It worked very well in my previous Galaxy Nexus phone.
Any idea?

A kernel with fast charge is inapplicable to your situation. You simply need ausb cable that had the d+ and d- pins shorted.

I have a UK I9505 S4 rooted, but on stock kernel and rom.
I use the device in the car with a Pioneer AppRadio2 & ARLiberator that connects my phone via the Samsung MHL2.0 adapter.
The problem is that as the USB charge (2amp charge for AC simulation) goes through the MHL adapter the phone only ever sees it as USB charging and I cant charge the device faster than I drain it.
Does anyone know if any of the current kernels in development for the S4 have the Chad Froebel Fast Charging patch applied?
I would ask in the dev channel but forum restrictions say I cant as the right question in the right location because I am a new user *dumb*
not yet it's a new phone wait a month or 2 and this place would be full of wonderful choices
I have the same on my pc, the battery level even goes down if i play a game while connected to my pc. Not really related to this thread but just saying

that's because the phone is not charging fast enough on my s3 the charger is 1000mah while the usb charge is 475mah so fast charging made it go up to 900mah and ur problem is quite the same as him
Any news on this, sorry for resurrecting this old thread, but I am desperate for fast charge to be enabled when at work and I charge my phone whilst connected to my pc!

If you have the Snapdragon variant, ktoonsez kernel had fast charge enabled.

Thanks for letting me know I am running KT kernel now, my usb charge has increased from 450mah to 1000mah and charges quite quickly just via USB2.
The only down side of that is you have to disable fast charge in order to use file transfer or it as a modem
It works though, thank you again. Link here to anyone wanting it. http://forum.xda-developers.com/showthread.php?t=2297379
I have finally switched the kernel on my UK Vodafone S4 to one that supports Fast Charge, the same one as above (Ktoonez).
I also switched to the wanamlite 1.4 rom for better all round performance!
In terms of charge rates I used a charge measure app to see what was going on and a standard USB delivered 450-470mA. When I plugged in my Samsung MHL 2.0 adapter to get HDMI out, that dropped to 300mA from the same source!
With fast charge enabled I can now get a full 1000mA with the MHL adapter plugged in, which was my main issue, so I am happy!
I just wish the Adam Kernel that comes with Wanam's roms supported fast charge switching as its an awesome kernel!
Hi All
I noticed that my charge time is very long even when i am on airplane mode ,, is there any way to enable fast charge or quick charge provided by qualc devices my device is (i9515 blackedition) rotted with stock firm ware and i know their is option called fast charge on note 4 so is their any option like that on s4 or even to enable quick charge 1.0 by qualc by using secret dialing code ... thanks in advance
So, I have a macbook air with 2 usb 3.0 ports. But, when I plug in my normal 3.0 cable that I got with the note 3.. it most certainly does not charge as fast as it should.
It's charging very slow.. am I doing something wrong here? Anyone else?
I see that it says use as a media device (3.0 device) but it's greyed out and won't let me select it.

Hey. I have the exact same problem as you do. I just got my note 3 and plugged it into my 2013 macbook air. It wouldnt chsrge at all even though it says charging. So I just plugged it to thr wall and it took just a little over an hour to charge from 25 to 51%. Is this normal?
Sounds like it has something to do with the Darwin Kernel guys. Apple will probably have to do a patch to fix it.

Hm, well I noticed that if you go to Battery under Settings, it shows as Charging (USB) when plugged to the macbook. However, if you plug it using the wall outlet, it shows as Charging (AC).
Its either in the Kernel of the Macbook, or the Kernel of the GN3. If its the Macbook, well it will probably never happen. If its the GN3 kernel, you just have to be paitient and wait for custom recoveries so we can flash kernels and roms that support FastCharge on USB. USB 3.0 can supply the juice, it just has to be told to.

Okay that makes sense. Thanks for the quick answer. Btw, does the battery life improve as time goes by? My Note 3 dropped from 90 to 60% overnight.

Think in milliamps yall... Your wall charger that came with the note is 2000mA... The usb3 port on your mac is 900mA... that won't even charge when the screen is on... just enough to keep it from draining... it will charge very slowly (less than half speed) if you power down the Note3.

That's correct, but newer Macbook Pro's have a neat feature. They can provide up to 1600 mA additional current (apple devices e.g. iPad), wich adds up to 2.1A. If there was just a way to disguise a Note as an iPad.

Yeah, but knowing apple its only for apple devices. Pretty sure it drops well below that for non-apple devices.
does the opo support Qualcom quickcharge 2.0?
iv'e seen a thread discussing this at the oneplus forums but didn't quite understand.
some claim that the opo do not have the required hardware to do so, even though its rocking the snapdragon 801 soc which should support it...
iv'e seen a couple of kernels claiming "usb fastcharge" - is this even referring to the same feature?
sorry if this question have been asked before, i still need clarification...
thanks for your time!
As a kernel developer (can you even call me a developer? I'm just meddling around, really, but I guess I learned a few things), I can answer at least one of your questions. No, the USB fast charge feature you're mentioning is NOT the same feature as Qualcomm QC 2.0. USB fast charge means that the kernel will treat USB charging as A/C charging, so that you can get A/C charging speeds even when you're charging from, say, a computer.
Stock kernels limit the amperage of USB charging? That's odd... Why? And what's the limitation?

You could end up damaging the USB port if you demand more power from the port than it is designed to provide. The most I've seen on a stock USB charger is 500mA, compared to the usual 2A or so on A/C charging.
Yes USB charging rate is 500 mA and AC charging rate is 2000 mA .

When I'm running CM13 with a decent charger and cable, I get "rapidly charging" on the lock screen.
I get insanely close to the 2A limit and the thing charges very quickly.

Can you tell me how much mA current you were getting in ampere app ?
All we need a basic feature to be enabled / developed by developers to kernel i.e Charge rate control.
Other features can be focused after this.
The most wanted feature we want from kernel is fast charge support.
Option to enable 2.1 or 2. 4 Amp charge input.
All other features are secondary.
To fully charge redmi 3s takes 3hrs. with input of 1.4 Amp.
Please work specially over this feature.
Whats your opinion?

Use Eximious Kernel ,Its capable with fast charge ,took 1hr45min from 30-100, You have to turn on usb fast charge by Kernel auditor . But dnt try to flash any custom kernel with miui base rom.

usb fast charge and quick charge are two different things. usb fast charge let you charge from pc like with regular charger and quick charge let you charge faster using fast charge charger.... stock charger is limited to 2A and no kernel implementation can change it....
