DS3231SN Power Consumption

Other Hardware 3rd Party Boards
1

Datasheet:
https://datasheets.maximintegrated.com/en/ds/DS3231.pdf

So reading about the RTC and reading many other topics I still couldn't understand some
points, the DS3231 consume 0.1mA depending on the voltage while working and
transmitting thru I2C, while not transmitting thru i2c and let's say we got the arduino on
sleep mode and the I2C disabled and as well using on the RTC only VBat with a decoupling
capacitor:

Questions:
-How much current will consume while not transmitting thru I2C?
-While working only thru VBat will it work normal / being able to transmit thru I2C?
-I will be able to get the temperature data while having only VBat connected?
(as power)

Info Pins:
I will use only SCL,SDA(10k pullup), VBat on 3.7v lipo, GND (all the NC GND), the others not connected

What you want to know is in this table, and nothing else matters.

Well good but still not accurate data as I need, well there is only one way to find out
test it on my own.

Not sure what you're looking for that isn't provided in the section of the datasheet jremmington cited.

Be sure to publish your results here. We are all dying to find out what you discover!

Still waiting for the RTC chip, when it will arrive I will do tests on the low power consumption.
