Does accelerometer send digital data through I2C?

Hi guys, so I have an arduino, which has two things connected to it, an EEPROM and an accelorometer connected through I2C I think. I was hoping to save some power by disabling the ADC (and I’m wondering what else I can turn off) on the board itself, and was wondering whether the accelerometer (ADXL345) would still function fine? (note: this is on a leonardo based arduino if that helps.)

Nick Gammon's page about power usage: http://gammon.com.au/power You have to use a bare-bone Arduino to save power.

You can disable the ADC, but it will reduce the power by almost nothing. There are power regulators on the board and other components that requires more current than the ADC.

I got to test it today luckily, and I was able to lower the power slightly, but as you say, a bare bone Arduino I would assume would definitely lower it a lot more. Unfortunately I won't have the time to utilise that option for what I want to do, but thanks heaps for your answer
