[Q] fast charge kernel

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.

[Q] Fast Charge Kernel Patch?

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

[Q] usb 3.0 charging/mac issues?

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.

USB fast charge, how to enable?

Im not sure if anyone would be familiar with this, but on my samsung galaxy nexus there was an option that was universal on all kernels called "USB fast charge"
which basically all it did was cancel out the support of file transfer while connected through USB, but in return gave much higher charging speeds through USB. With it enabled my galaxy nexus would charge almost 4x faster.
Is there an option for this on the note 3? I have not rooted yet, but will in the next few days. I understand its up to the kernel dev's and whatnot to implement it in, but is this feature available on the note 3?

We can't flash kernels

Bootloader Locked, can't flash Kernels, but the Note3 charges pretty damn fast using the Stock Cable plugged into an A/C outlet.
Total Segue here, but as a Brother to two gay siblings and an Uncle to a gay nephew, can we refrain from using the therm "that's so gay" when it comes to something derogatory?

with the wall charger the note 3 came with, reallly fast. Just as fast as you stated. But through USB, slow as molasses, probably 1% every 5 minutes. which is why i was wondering if the USB fast charge option was available. On my galaxy nexus charging through USB, it was just as slow. With USB fast charge turned on, it charged as fast as a wall charger through USB.

Hmmmmm, odd. Does your machine have USB3 ports? I know that's supposed to be good for only speedy file transfers, but I wonder if it also speeds up Charging? I've just never noticed slow trickle charging from my computer. The only time it's slow is when I use a regular USB2 cable in the car....then it's slower than molasses in January.

I do have USB3 available on my computer, but havnt tried it for charging yet. So far my USB charging has been done through my car which is some random usb 2 cable. Which now that i think about it i believe its only a 1 amp charger in my car, if that. It was enough for my galaxy nexus but probably not so for the note 3. The note 3 wall charger is i believe 2.0 amps?
Im wondering if charge rates matter through usb2 / 3.
If i get a 2.0 amp car charger and use it with a usb 2 cable, will i still achieve 2 amp charging speed? Or for the note 3, i have to use a usb 3 cable?

Not sure. My Laptop has a USB port that charges devices even when the Laptop is turned off, but I do know that my Nexus required less juice to charge up, where the N3 doesn't keep up when I charge it in the car, so I think it's the 1 / 2amp question

How long should it take to charge?

My Sprint GS5 takes around 1 1/2-2 hrs to charge form 10% up to 100%. How do I enable USB 3.0 mode so my phone will charge faster? Thanks in advance.

Just use the USB 3.0 charging cable. Not much else to do. The charging speed might be different for wall vs. computer.

What is the USB 3 charging cable? what kind of cable is included in the original package? I also suffers from slow charging, might be because I connected the USB cable to an iPhone usb adapter (because I have US plug, and i'm using EU).

It means that charging faster will reduce the overall life of your battery because the battery and phone doesn't support it. The Galaxy S5 supports USB 3.0 and Qualcomm Fast Charge.
Also, the fast charge on your Ace 2 just means that it will draw maximum power from USB ports. It doesn't change charge speed with a wall adapter.

My gfs s5 is charging so slow. About 2 hours charge it goes up by only 20/30%. I am guessing this isn't normal? That is using the wall charger and not sub.

seems a bit slow.. you are using the adapter it comes with? are you doing anything intensive with it while it charges? ex skype or something?

Use the original cable and adapter. If you think that's too slow to charge, like taking up to 5 hours, that's unusual. Let your carrier or the store check it for you.

Yeah, using the cable and adapter it came with. Nothing is getting used when it is charging. It must have taken about 6hrs to charge during the night.

This is just wrong. I think my charge is almost 1% per minute - pretty quick.

Hi. I have a G900F and I have noticed that my new S5 charges much slower than my old S3.
If I check it with "Galaxy Charging Current" or GSam Battery Monitor" it says that only 450mA is used even though I have connected the phone to my Laptop using a USB3.0 cable on a USB3.0 port.....
Any advice please. Thank you!
