power useage while docked
 

i have a question from time to time i find that i need to share my phone internet connection but when ever i do have the need to do this i find that my phone stops charging the battery it dose not use the power supply from the usb connection as a alt power source and begins to rapidly drain my battery
to the point with a full charge im lucky to get 3.5 maybe 4 hours of use
this also happens when i use my GPS or stream internet radio in my car for those long road trips
i have "when device is turned on,do not charge the battery when connected to a PC" UNCHECKED


my question is this
is there a ROM or setting that would make my phone
a:charge no matter what app or service i was using
b:after the battery is charged to draw power from the USB supply instead of a constant draw in the battery

also is this normal for the phone to switch from charging when the shared connection function is used

Well another problem may be heat as well, try opening the keyboard to see if that helps. But USB does not give that much power on some machines. I use a USB cord from one of my harddrives that has the second USB plug. It helps charge faster due to collecting power from two plugs.

+1 Elmerfudpucker. Heat is the enemy. Also make sure since you're tethered that you can keep any addl radio devices off on you phone. E.G. turn off bluetooth & wifi if they are on for some reason while you're tethered. Those two items will increase the heat buildup quick.

I also lay my device face down on the table when tethered with the battery cover off since most of the heat radiates from the back.
