Phones turn off their radio when the screen is off and go into a sleep state (waking up in intervals). Keeping the radio on 24/7 is just going to increase power usage by a lot. It's not the CPU that's the concern. Even ignoring this issue, it would open your phone up to getting DDoSed by strangers on the internet.
