Battery drain/charge rates

[supershare]

OK guys,

Most of the OEM chargers do not tell the TP that it can use the maximum charge current the phone supports.

I playes with some USB cables and a ampere-meter I had laying around and found the following:

Plug it into a OEM USB charger and it will charge at about 450 mA @ 5V.
(This is ehough to run Wifi and the display, but if you also use the CPU hard (i.e. gaming) you will drain your battery although it is plugged onto a charger.)

If you want the phone to charge at maximum charging speed it has to think that it is connected to the original HTC wall charger. To theck this the phone checs the resistance between the two data-lines of the USB cable.
So if you have an OEM USB charger which can provide 5V 1A you van cut a USB cable, let the power-cables (usually black and red) untouched and bridge the Datalines. (I think they are white and green... ) To save you computer in case you plug this cable into your computer just leave the green/white cables unconnected on the PC side...

Now you have a Fast-charge-cable.

have fun!

Even the HTC charger cant keep up with the power draw of an active phone call. It wont die on you, but it wont charge much either. At least according to the mah battery monitor on KK's ROM.
