No matching specifications. Try a different word.
Specifications from the RF Safe source record. Regional variants can differ; source software details may predate later updates.
02 / REPORTED SAR
Six readings. More context.
SAR describes radiofrequency energy absorbed per unit of tissue mass under specified test conditions. These reported values are not a measurement of your everyday exposure or a safety score.
Cellular only
Cellular + Wi-Fi
Values match the rounded RF Safe dataset used in our comparison tool. Test separation and averaging details are not included in that dataset; check the original filing for your exact variant. These are phone values, not case-performance results.
03 / VISUAL EXPLORER
Take a closer look.
RF Safe’s age-based illustrations repeat the phone’s reported SAR values across age panels. The shading is illustrative; it does not measure absorption in children or predict an individual’s dose.
