Smartphones have become an integral part of our everyday lives. From
work and school to daily tasks, these handheld devices have brought
everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, as Visual
Capitalist's Anshool Deshmukh and Sabrina Lam detail below, given that
our phones emit a tiny amount of radiation, we’re exposing ourselves
to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of
Radiation Protection, we visualize the radiation emissions of some
popular smartphones in the market today.

Radiation and SAR Values of Smartphones

Smartphones and other mobile devices emit tiny amounts of
radiofrequency (RF) radiation. Humans can absorb this radiation when
the smartphone is being used or is lying dormant anywhere near their
bodies.

The parameter used to measure phone radiation emissions is the
Specific Absorption Rate (SAR). It is the unit of measurement that
represents the quantity of electromagnetic energy absorbed by the body
when using a mobile device.

The Council of the European Union has set radiation standards for cell
phones at 2.0 watts per kilogram, measured over the 10 grams of tissue
that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at
the body (kept in your pocket). For the purposes of this article,
we’ve used the former calculations.
Smartphones With the Highest Levels of Radiation Emissions

The Motorola Edge has the highest radiation emission with a SAR value
of 1.79 watts of radiation per kilogram. That’s significantly higher
than most other smartphone models in the market today and close to the
limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the
OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus
with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the
top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Now that we have detailed the worst offenders let’s look at the
smartphones with the lowest levels of radiation emissions.
Smartphones With the Lowest Levels of Radiation Emissions

The smartphone with the lowest SAR value is the ZTE Blade V10, with
0.13 watts of radiation per kilogram.

Mobile devices by Samsung carry some of the least radiation risk. The
company has four phones considered to be the best in the category. The
Galaxy Note 10+ is the best model in their line-up, emitting a meager
0.19 watts per kilogram.

Here is a look at the 10 smartphones that emit the lowest levels of radiation:

There is currently no significant research proving the harmful effects
of phone radiation.

Despite this, people who are in contact with their devices for
extended periods can at least quantify their radiation exposure and
make choices about which brands serve their needs.
