FM radio on your phone: why it is useful during power cuts

FM radio means receiving stations in the FM band (87.5-108 MHz). Some phones have a built-in FM tuner that works without mobile data and barely touches the battery.

FM radio works without internet

In plain words

Internet radio is like tap water: it flows as long as the pumps and pipes are working. FM radio is like rain: it falls from the sky for everyone, and to "collect" it you only need an open glass - an antenna. Even when the power and mobile internet are down, radio stations often keep broadcasting.

How it works

  1. The radio station sends sound by modulating the frequency of a radio wave.
  2. The phone's FM tuner tunes to that frequency.
  3. Wired earphones are often used as the antenna.
  4. The tuner extracts the sound and plays it.
  5. No internet or SIM is needed.

Broadcast radio reaches everyone, like rain

Where you'll see it

Many budget and rugged phones have FM radio (Xiaomi, Redmi, Samsung Galaxy A, rugged Blackview, Oukitel, Doogee), as do feature phones. Flagships and iPhones usually lack an FM tuner. Specs say "FM radio".

Does it matter when buying

It is a very practical feature for an emergency kit and power cuts: news without internet and with minimal battery drain. If you are choosing a backup phone, FM radio is a plus. Check whether you need wired earphones as an antenna.

Myths

  • Myth: FM radio on a phone uses mobile data. Reality: No, it receives the broadcast signal directly.
