Editors' note: This list is current as of April 26, 2011. Some handsets that CNET has reviewed in the past may have lower ratings, but we've removed them from this list if they've been discontinued.

The specific absorption rate (SAR) listed here represents the highest SAR measured with the phone next to the ear as tested by the FCC. For a phone to pass FCC certification in the United States, it must have an SAR of 1.6 watts per kilogram (w/kg) or lower. Handsets are listed from lowest to highest SAR, with the last phone on the list having the highest SAR.

By publishing these lists we are in no way implying that cell phones are dangerous. Also, we are not implying that a cell phone with a lower SAR is inherently safer. Rather, we are giving you the tools to make a choice based on your own concerns.
