Hi there,
In speedmod kernel there is fast USB charging speed to same speed as AC charge feature.
I want to ask is it possible to enable fast USB charging speed in stock kernel/CF-Root? Maybe CWM flashable script?
Thank you.

even the fast USB charge mode cannot match ur AC charge speed ma8
the mode just ensures that when u connect 2 the computer the mass storage is disabled and ur phone will only charge no data transfer happens

I don't think so. I can still copy data to USB when USB charging in speedmod kennel. It is only related with the charging voltage modification.

Hi,
My phone charges extremely slow when connected with USB to my MBP.
I checked with the OS X tool "USB Prober" and it says 96mA, checking my old iPhone it shows the correct 500mA.
What might cause this, and how may i fix it?

No one knows?
At what power-level was your phone when plugged in? Because when it was already in the 90's, it charges slowly since the LiIon charge cycle is meant to work that way.
Oh, that might be a very good point. I will let the battery drain a bit before i plug it in the next time.
It seems to draw 96mA still, even if the battery was down to 75 %.
This would mean, your phone needs about 19,8 hour to load to 100 % from 0%. (1900/96)
It is correkt ?
When connected to USB it definitely sounds correct, it takes extremely long time to just move one percentage up. Even when the phone is not in use, and the display is off.
19.8 hours should mean 5 % an hour, and that sounds very correct.
Do you have also the problem, if you charge via a AC adapter ?
While I had it I found out that if you take a car charger or a usb cable and solder the two inside pins together (the data lines) it tells Android you are on a wall charger and charges at the higher rate.
If you use a special usb charger cabel, it should work
Using the AC adapter it charges normally.
I will see if i can mod one of my cables to short the data lines.
Thank you
Are the SGS II enumerated properly, that is the USB drivers are loaded so you can browse the SD card or connect with Kies or similar? Before a USB device is allowed to draw more than 100mA it has to negotiate this with the host. And the USB port has to be capable of delivering 500mA but since your iPhone shows 500mA this should be ok.
I think so, yes. If i chose to mount the SD cards i can fine browse them and upload files etc.
I can also use ADB when connected.

Same situation here...
The phone negotiates only 96mA with my Win7 PC; other devices, on the same PC, negotiate 500mA and the phone charges fast with wall charger.
Does anybody know hot to bring my phone to 500mA on PC?

If you dont mind flashing a kernel try dori or gustavo's. The app where you set the kernel level params, e.g. synapse or stweaks, has an option where you can set the current the phone can draw from a usb connection. By default its 500 ma only.
Btw,did you see the same results with different usb cables/ports/pc?

I'm using Apolo kernel and it is set to use 450mA from USB (default), but the phone only uses 96mA...
I've installed cMiui on my Samsung Galasy SII and i noticed that plugging the usb cable to the computer the phone starts the animation of the battery but it does not charge.. i have changed kernel with siyah and finally I did a wipe-battery but nothing has changed..
Charging with adapter is OK, but i need however I would charge it with the usb..
help me, thanks
In ExTweaks in Misc card you'll see charging voltages. Change all values to 650 mA (each USB port has 1000 mA so it isn't risky).

Thanks for reply.
Today i test this setting.. I hope to resolve
However, it seems strange .. The default setting should be 450mA like now?
Before with stock formware the battery is always charged me via usb
Solved
Thanks przemcio510..
I solved with your setting!
Now charging via Usb it's fine :good:
Folks,
Using the Siyah kernal for a while now and its been amazing.. Well, I have seen an option under Stweaks to increase de amperes for USB charging..
Default is 475mAH which causes slow charging.. Is there any harm if this is increased and upto what level can we increase it?
I put it to 900 no harm to mention.

it may very well damage your usb port on a long run.
Recommended max power output of usb 2.0 is 500ma, (in gaming computer it may be more) on usb 3.0 its 1000ma .
So, determine which you have got. In laptop it will be even less...
If you are not using computer usb and other usb charger you can increase it but keep in mind charging in high amp. will shorten life of your battery too...

Why using an ac charger dont damage the usb port?
USB & AC charge at same speed here... I've set USB @550mah & AC @750mah so i think there's a problem with STweaks (or what?!) :s
When you say usb port am I right in thinking you mean the computer and not the phone?

hi frens i have got s3 n in stweaks in ac current i set the value from default 1000ma to 1200ma.wil this gonna hurt my s3.coz its taking lon time for a full charge,so done this
pls reply whether its a danger

Read that ... But basically anything under 1470 should be fine
No damage.

Hi Guys,
Is it just my phone that is slowing down in CPU speed when connected to a USB cable PC USB or Charger?
I was getting about 50% less cpu speed with usb debugging on, turned the feature off and now it's only about 10% slower, is this normal?
I'm on stock 4.1.2 with Perseus kernel. Same "issue" with the full stock rom.
isn't it obvious that questions go in the Q&A forum?
hi i just broke my charger .. and customer care is so far to buy new original one .. i am using the custom kernel
i know the charger provides the 650ma of current to the phone to charge but the USB data cable through the pc provides only 450ma and relatively charges the phone slowly
well there is a way to change the current to 650ma ..
i just want to ask that it i change usb current to 650ma it will harm battery ?? or my phone ??
it is same as charging with charger and usb providing same current ???
i should charge through the USB @650ma or not ?? thats all what i want ..
If anyone know the answers please share .. thanks

Increasing the USB charge current (stock val 450ma) (via supportive kernel like Dorimanx etc) is always risky, both for ur phone as well as ur Computer USB port
