[KERNEL PATCH - Devs only] Force AC (fast) charging

This is for kernel devs only. The patch is useless to those who do not/can not compile their own kernel.
I put together this patch for you guys at the request of a few different members here in the nexus forum. This allows one to force AC charging for any charger that is detected as USB (i.e. car chargers, inductive chargers through the pogo pins). This also works for MHL, HOWEVER you will most likely still be limited by the MHL adapter itself. With modification to the MHL adapter (splice in an additional charger) plus this mod, bunklung was able to charge at ~600-700 mA while mirroring and streaming.
To toggle the fast charge you must download IncrediControl v1.5 beta3 (http://www.incredikernel.com under Latest Downloads). Under the general tab, click on force fast charge, then apply. After you have done that, place your phone on the charger. You will see it is now detected as AC and if and only if the charger can put out more current than it was previously being limited to (more than 500mA) you will be able to use the additional current.
Good luck have fun.

NOTE: You may get a freeze/FC in IncrediControl once in while when toggling the charge. This is being worked on. I figured everyone could deal with a FC here or there to get this out earlier.
Fast charge toggle widget. No more need to open the app to toggle!

Cool! I look forward to seeing how well it works in practice. My car only sends usb power.

Looking forward to a dev adding this to their kernel. While we wait, any chance we could get whatever reference kernel you compiled for the people who tested the kernel? I'm dying to try this with pogo pin charging and touchstone mod.

Thanks for your work, added this to latest Trinity test kernel.
IT'll probably make its way into the Trinity thread tomorrow or so, unless the F5ers out it before then.

@chad0989
Wow thanks, cool mod, cant wait to try this!

Pushed the fastcharge toggle widget to the market for those who were interested. No more need to open an app to toggle when you can just do it from your homescreen!
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget

Issue with the market should be straightened out now for anyone who was getting a not compatible message.

The widget should be fixed for you gnex guys, hopefully no more FCs. Sorry about that!

Fast Charge Toggle Widget appears to be working fine with LeanKernel 2.6.0 and CyanogenMod 9 Nightly 20120319 on my Galaxy Nexus.
Thanks!

if i understood correctly, this doesn't produce any plus effect if the output usb port is limited to 500 mv right?
and the output of every standard laptop usb port is only 500mv or i'm wrong?
thanks in advance

Aww, fast charge widget costs :/

That's correct. Although some will definitely put out more, my laptop puts out ~800. I'm not willing to say I personally recommend charging from a USB port because there is a risk of damaging the port/motherboard, although nobody has ever reported actually damaging it (I do it all the time).

[Q] S2 9100g and 2.1 A charger ?

Hello everyone !
I use 9100G for the navigation while driving and noticed that my car lighter / usb adapter declared as max 1000 mA doesnt give enough power to charge, or at least keep the battery at my phone while GPS is on (screen also on all the time).
S2 doesnt drain battery too fast but it drains it percent by percent and if the route is long then it wont last enough.
Thatswhy I bought dual USB car adapter - one port is 1000 mA, other is for the tablets 2100 mA.
Tested the one with the 1000 mA and its same story as with my previous adapter (no wonder since output is same) but Im wondering can I connect S2 to 2100 mA port ?
It surely have enough power to keep the S2 alive and probably to charge it in the same time but Im not sure will I damage the phone and battery ?
Any real life experience about this theme ?
ps
I have read existing threads but no one specified that used 2.1 A with S2 without problems
Thanks m8s !

There is a good chance that 2100mA might damage ur battery buddy coz when the output current is more than standard then the battery heats up too much than normal. One of my friend's battery was damaged using a charger with diff output current.

You can freely use 2.1A charger. Your handset will control charging current and it won't take more mA than it needs.

Don't know exactly how it's going with i9100G, but i9100 can take up to 650mA current and no more, doesn't matter what source you have. And that's hardware limitation, you can't change it with kernel.
For you, I can only say - check if your phone sees your car adapter as AC charger or USB connection.
When it is seen as USB, it draws from source up to 500mA. To make your phone see your adapter as AC charger you need to short out data pins(2 center) in USB cable. It's cable white and green. After that it will take more power but still I guess it will recharge slowly.
I have preety cool power source [email protected] but still I don't mind modding it to MicroUSB because it will charge as fast as stock 0.7A charger. That's lame :/

You can put it on 100A charger, it will take only 650mA.
Wrong voltage, or some noise and static electricity can kill your phone, not charger strength.

Be aware of knowing that some navigation apps uses more CPU than others. For example in my country (Poland) is popular a navi called Automapa. It`s great but it uses CPU more aggressively than other navi apss and my phone even if on efficent power adapter is loosing battery. On Sygic/TomTom the problem doesn`t exist.

As several people pointed out already, you can safely use 2100mA port. The 2100mA is the max amount of current the charger is capable of supplying. The phone's internal circuit (i.e. resistance) will determine how much of that 2.1A is drawn to charge the battery.
With that in mind, you will not see any difference between using 2100mA and 1000mA port, because 1000mA is already higher than what the phone will use, which is around ~650mA. Thus, if you couldn't charge the phone while using navigation on 1000mA port, you will experience the same thing on 2100mA.
Of course, this is assuming that the 1000mA and 2100mA ports indeed output 1000mA and 2100mA respectively.

Thanks for the reply, I ve checked the forum thoroughly but didnt found exact answer, anyway I tested it by myself and reults are
1000 mAh is not enough to give sufficient power to charge a phone while GPS is on (screen on) with WI FI and mobile data
2100 mAh is enough to give sufficient power for the task
Phone perform normally, slight heating under the camera at the back side but thats common while charging anyway
Thanks for the reply

It sounds like the 1000 mAh port may be supplying something less than 1000 mAh then.
Oh Well. As long as 2100 mAh port works

Check when charging with 1A and 2.1A if phone see connection as USB Charger or AC Charger

[Q] Charging stand capable of 2A/fast charge?

Hi all,
Long time lurker, first time poster here. I have searched, but the few threads I could find went cold a while ago with no definitive answer.
Does anyone know of a cradle / stand / dock charger that will utilise the full 2amp potential of my cable when charging?
When charging direct from the plug and cable, Battery Monitor app shows just shy of +1900mA (estimated, but good enough for me). When I connect the same cable to either of my two stands the app gives readings of 500mA - 700mA.
I thought the dock was just a dumb extention of the cable, and did not expect it to throttle the charge rate. Admittedly both stands are relatively cheap from Amazon, but both are 'designed for the Note 2' so would have thought the fast charging would have been a key feature..
Has anyone run into this problem? Anyone found a solution? Or am I just way too impatient? :laugh:
Cheers!

You need to install a kernel which supports it like Perseus ot redpill.

I'm currently using Note2Core EX v3.06. I guess it doesn't support 2A docks, but it does 2A charging cables. Can the phone tell the difference between the two? I was not aware.
Thanks

I should clarify I am only talking about charging from the mains. The cable alone gets 2A charging rates, but add any charging stand to the equation and I get just over a quarter of the speed I normally would.

If charging stand is considered usb then it would be normal

[Q] Fast charger

Can anyone with a Find7a let me know what the spec of the vooc charger is? They don't seem to sell them separately on the Oppostyle website and I usually like a second charger for work.
Thanks

Have it at home and am in the office (i get your point xD)
But i read in another thread, that it has extra pins for full power charging. Without that extra pins you dont get full speed charging.

4.5 amps instead of the usual 2 you see on the market.

That's annoying. I was hoping it was just a higher amperage. They sell N1 chargers on http://europe.oppostyle.com but not Find 7a ones.

The 4.5 amps are reached by having multiple power lines on hidden extra pins.
So yeah, vooc is proprietary, no way around it.
Gesendet von meinem One mit Tapatalk

But if we are already talking about the charger i have two questions as well.
My overall understand of charging and power tells me, if i plug the vooc charger in another phone it will load with the amperage the other phone accepts. So there should be no damaging - right? I dont feel ready to test it without asking you before that
The other way around, using my old charger with me Find 7 should work fine as well, shouldnt it? Of course with even longer loading time depending on the power of the charger. This night I tried charging my Find with an old charger of my Galaxy Nexus (I think something around 1A which worked well with my Nexus 4). I expected it to load waaay slower. But actually it didnt load at all. I am not absolutely sure at wich perantage i started, but after about 8 hours i got no remarkable change, maybe a few percent. Is there a minimum Amperage needed?
Thanks for your thoughts

You are correct.
The extra voltage is pumped out via additional pins that a normal USB connector doesn't have.
The other way around you can of course charge the find7 using conventional USB chargers, just slower of course.
As for minimum amps... All my other chargers give me 2 amps and that works.
Also charging on my computer via a USB port works great... Those output I think only 500ma...

If you plugged the VOOC supply into another phone it shouldn't cause electrical damage - but the extra pins on the charger COULD get damaged.
It's more than just the extra pins - the VOOC power supply uses two pins (possibly D+ and D-) to communicate with the phone.
You'll get normal (but fairly rapid, I need to check but I think it's at least 1.5A) charging using a standard MicroUSB charger.
Edit: Can't find the exact settings, but the charger chipset supports settings of 3A, 2A, 1.5A, 1.2A, and some lower settings. Stock is probably 1.5A or 1.2A

That's some good info there so thanks guys.
It still begs the question, how do you get hold of spare or replacement vooc chargers?

Minimum power spec?

It's a shot in the dark, but does anyone know the minimum power you need to charge the 5X? I have a device that puts out 1.6A and the 5X won't charge/connect via A-to-C cable.

Taking a look at question and answer article Google officially released here it mentions "the charger’s output voltage is DC 5V, 3A". It may be charging with that cable just incredibly slowly as the article also mentions. Hope this helped and let me know if you still have questions !

Thanks for the response. I'm actually having issues with my Android Auto unit since switching to my 5X. I previously had a Nexus 5 attached via a 3A USB (A to microB) cable and everything worked fine. Along with switching phones, I had to switch cables, and I think there's my problem. The Pioneer 8100NEX (head unit) can out out max 1.6A, and there must be something going on with the power draw. I was getting error messages that indicated the connection might be short circuited.
I was using a USB 3 cable (3A, 5V, A to C) that works fine through a wall charger or from a computer. My next step is to get a lower power cable and see if that works. Anyway, my battle continues.

I got the same error out of my Pioneer x4700 the first time I hooked it up. I haven't seen it since... I think I recall only seeing about a 5-600mA charge rate when I first set it up (though I have a port that only supports 1A).
