NO, I don't have any LED on the board. It is Voltage depend problem, I think. but why?

You Connection Parameters will determine your current consumption while connected. You likely want to update to a slower Connection Parameter if you want to reduce current consumption. Do you have any LED's on the board? If so what color?

My application when Adv uses 300 uA in Vcc= 3.3 and send data when it's ideal use 160uA but I don't know why when I change Power supply voltage to 2.7 it uses 1.5 mA? sorry, I don't Understand your questions. I program by Keil. not in debug mode. in release board.

So a few things to look for:

What is your conection / advertising interval?
Are you running release firmware or debugging?

I use S130 SDK 11 ver 2 alpha, and I don't know about DC-DC. No heavy process(I don't think so!) . if I had a heavy process so why my average current in Vcc = 3.3 is 160uA?

What firmware are you testing with? It sounds like you have some heavy processes going on. Also are you using the DC-DC?
