Well, this kernel supports fast charge and if you want you can try this app which turns off your screen while MHL enabled.. Good luck

[Q] Charging the HTC Legend

Hey just wondering if I use a AC adapter to charge my Legend via USB, when its plugged in I can't unlock the phone, the screen seems to only recognise touch for about half a second, eg. I can swipe my finger to use the unlock bar but it only goes about half way to the right and the same thing for the mute button, it only goes about half way to the left.
Charging via USB connected to the computer works perfectly but it's just when I'm charging via AC adapter. Thought it was weird - might have something to do with the phone getting too much electricity through the AC?
AC charging works fo' me
It should work the same with or without charging.

[Q] USB 2 Wall Charger adapter disable touchscreen...

Hey guys...
I bought a usb to wall charger adapter, so I could get a fast battery charge and usb connection with just one cable.
But when I connect the adapter to the energy, my phone's touchscreen freezes... I can lock/unlock, and what is happening on the screen (e.g. a movie) continues normal... But I can't interact touching in it. It's like the touchscreen feature is disabled, and becomes just a non-touchscreen display.
Anybody has tried it before? Sucess? Same problem? Wonder why it happens?
Thanks in advance!
It happens the same with me. I bought a cheap one on Ebay.

Charge tab 2 via usb!!!

As we know that we can not charge tab 2 via usb when connected to pc.
But there is a way:
do not insert whole usb to port at once.slowly insert the usb(connected to tab) to port(of pc) upto its approx 1/2-3/4 portion.you will see charging symbol on tab battery icon.it may take some time to figure it out.but it works.....
Note:it works on p3100 for sure and may work other models.
ENJOY!do not forget to hit thanx button...
a video demo how to do this should help :cyclops:
it works! thanks for the tips

I wanted to add a clarification: when plugged into USB the notification popup indicates "discharging". But in fact it is charging, because the % charge goes up (slowly) with time.
The trick mentioned in this thread may make the tablet show 'charging', but I doubt that it makes any difference to whether it is really charging or not. The charge rate is determined by the max amps of the charger. The supplied Samsung charger is rated approx 2A; if you use the USB from the iPhone charger it is approx 1A (if you have USB 3.0 ports, that is also about 1A); but USB 2.0 gives you only 0.5A.
As said...charging over USB is painfully slow (2,5-5W). I prefer to charge it with the original adapter (10W )

The tablet or phone will sense if the connection to the charger is AC mode or USB mode, if AC mode is detected then the tab will pull up to ~2.1 depending on the available rate from the charger, if USB mode is detected than the tablet will only draw ~0.5A.
The way the charger is configured will let the device know if it is an AC mode charger or if it is an USB mode charger.
By shorting pins 2 and 3 together on some chargers/cable the device will detect AC mode and it will pull more current.
I have a 1A 12V car charger that was wired for USB, an android device will see it as USB and pull only 0.5A, but an Apple device will pull the rated 1A. I shorted pins 2 and 3 and now android devices pull up to 1A, I am not sure but I think it is no longer compatible with apple devices (I don't own one).
It will say that it's not charging when plugged in via USB, but if you have it plugged in, it will charge, slowly. It takes forever if you're anywhere close to having a dead battery, and if you have wifi and other stuff turned on, it will take even longer but it should work, no tricks needed.
Thanks! Works on the 3113. It's shows charging and doesn't show as media device on the laptop. Nice find.
Hi.
I have a couple of these usb adaptors, see link below, I bought them years ago for the original 7" galaxy tab but i never used them.
If i plug my tab2 into an usb2 port i get the red cross on the battery icon, so i tried one of these adaptor and my tab2 is charging from an usb2.0 port on my notebook and according to battery monitor widget pro at 14% an hour, and i have a lightning bolt sign in the green battery icon.
I did a search for the adaptor i bought and i think i have found it for £6.50 each, see link below.

the tablet charges anyway so the icon says no
In 4.0.4 rom the charge icon its fixed, anyway charge by USB is too, too slow, only use for emergency

[Help] i9505 battery drain even connected w/ charger.

I need help, my s4 i9505 drain battery fast even connected to a charger. I don't know how to solve this issue.
Thanks in advance....
Do you use the original charger with original cable? Is it possible your usb port has some moisture damage? When the battery is charging, go to battery info and does it say usb?

[Q] MHL output

Hi,
Has anyone have problem on MHL kept on running and draining battery even after the cable has been unplugged from the phone?
I thought, after watching the MHL output on TV the phone battery was at 60% when I went to sleep.
I had plugged the phone to my MacBook Pro for charging but I found the phone is warm and battery level at around 40% when I woke up this morning. So, I powered it off and connected it to the charger to let it charge.
If the MHL capability does not terminate itself after using, then, how to manually terminate the MHL function without rebooting the phone?
settings - nfc - screen mirroring off.

This setting does not involve MHL/HDMI output.
Screen mirroring is used when device is used with a EZMirror device such as Tronsmart T1000 Mirror2TV Wireless HDMI display.
The question I asked involved MHL cable physically plugged into the phone.
