Phones maintain a cellular connection even if most data is being transmitted over WiFi at any given moment
Cellular modems are constantly reading and broadcasting messages to the cellular network unless they are explicitly turned off

- DrBenCarson 2y agoSure. But they also use a massive amount of power when they’re out of range so constantly searching for the network Turning off your modem is second only to turning off your screen if you’re looking to save battery
- FollowingTheDao 2y agoNot nearly close enough to when they are receiving data, especially video. When actively receiving data, a cellular modem will use significantly more power than when idle, with the exact amount depending on factors like network strength, data rate, and the specific modem technology, but typically ranging from several hundred milliwatts to a few watts
