This question already has an answer here:

I am currently having a look at the power consumption of a lenovo k900 phone and on the hardware side it seems Radio and Screen is using most of the power.

I am planning to use wifi but not the radio. Are they disconnected ? If so, can I use just the wifi, but no radio/telephony ? Are the settings or commands/intents to access these settings ?

This question was merged with Possible to turn on Airplane mode with WiFi on only? because it is an exact duplicate of that question.
