I have an HTC wildfire phone and I'm looking for way to trick this HTC to think it's connected to the original charger. I don't have original so i can't open it to measure. Right now for charging I'm using the USB port built inside a power inverter for solar installation. I also tried a car charger, rated as 2A, but still charging is very slow.
The problem is I notice the charging is very slow. I have took up it almost all night to get fully charged.
When I play music on phone and display stays on, it discharges faster than it charges.
I set up my little test experiment installation
For test's i got female usb plug, and i hook it up into my work bench psu, set to 5V.
Current draw 390mA (hmmm, it's looks like safe USB current draw)
I start search internet, and found information about shorting data lines together.
I do, this but current not changed. Still 390mA.
Shorting both data lines to GND also won't help.
Does anyone have similar problem, and found way to make my htc think it's being connected to fast charger and took >1A charge ?
