I used my usb OTG cable to charge other devices from my S2. Has anyone else tried it? Harming my battery is what worries me.

Harming it? Not likely. Draining it dry? Definitely.

Not dangerous. It disables the data pins so the phone thinks it's plugged into a wall charger.

I just use a wall charger. Tmobile brand and I use the usb cable for the pc. So the paper mod is for the pc charging?
Sent from my SGH-T999 using Tapatalk 2
Yes, it puts it in fast charge. Probably depends on the USB port's voltage as to if it works, I'm using front panel port on my Mac pro at work.

Can someone make a video regarding this method? I maybe retarded or something. I get that disabling data can trick into fast charge. But why not just disable data (USB connection) in the settings? Wouldn't that be a same difference?
Please someone make a video to show and confirm this. I also know that amperage can make a difference in charging method. Will non-high voltage with this mod will enable it like the wall charger??

Its not just "disabling" data ports on the USB.. Its built into a kernel from source, there is no third party app that can enable this. If it simply disabled the "data" functionality of the USB then simply cutting the cable apart and cutting out the two prongs would enable this but it doesnt. It is kernel based stuff.
The kernel pretty much can tell whats plugged into it, AC Charger, USB Charger, Car charger.
When you enable fast charging you are only able to enable it for the last two options. Enabling simply tells the kernel that it is able to charge faster based off of how the kernel is coded. If you have source code for the kernel, you technically could tell it to charge at 1000mV (1 volt) but that would destroy whatever charger you are using for nothing can charge that fast (yet)
Simply put, fast charging is a kernel level mod that no third party app is capable of enabling without firstly the kernel supporting it.
Not sure if this a ROM, kernel, or hardware problem but lately my phone has started to discharge if I'm using it on the charger. It'll charge normally but when I start using it, it gets hot and I lose battery. I'm running the latest stable vanilla rootbox with ktoonz kernel.
Sent from my SGH-T999 using xda app-developers app
That sounds normal to me. If you're using more than you draw, you'll lose instead of gain and the battery will heat up even more.

It's just math and physics.
If you are gaining, say 1A per hour and using it at a higher rate you will necessarily lose charge instead of gaining it.
Anyone's phone will do the same, that's just how batteries work. They heat up if you're putting them through a lot of stress - like continuously putting energy into it while taking it away at the same or higher rate.
If you want to continuously use the phone, buy a set of spare batteries and rotate them in and out.

Might be your usb cable/voltage output/ whatever u use to charge ur phone. Not enough power to charge it fast enough when you are using it.

+1 on this. Try killing background processes and wait for battery to keep up with usage. Sometimes battery can't keep up with active processes..

I'll give that ROM a try, i wasn't experiencing it with the stable release of rootbox before the current one. What kernel are you using?
Sent from my SGH-T999 using xda app-developers app
i had the same issue and I just switched cables, seemed like mine had some loose wiring or something and charged hella slow. so maybe check your cable first, switch chargers and then look and see if that helps

I'd try another cable too. On stock rom I had no discharge while charging issues so there is no reason you shouldnt be able to charge normally again.
Also check the usb port on the phone. If it's dusty try blowing into it. Check that it isn't loose also.

I have a relative who is has note 2 that was recently rooted. We have gone through many different roms trying to resolve the issue, but to no avail. The phone can sit on the charger for over 12 hrs straights, and will not reach 100%. currently it has been charging for 8 hrs, and is only at 35%. could the wise minds of XDA assist me in coming up with a solution to this particular issue?
Likely a faulty usb cable.

The note 2 uses a stock 2amp charger. If you are using any other charger, you will have that problem. Most other chargers only output .5amps

How can i tell what charger is correct?
I mean, not all charger for the smarthphones operate at 110-220V and has 500mA to up? I though that a higher amp --> less time to charged
Pc is unable to detect it ...
