Smartphone Radiation (SAR) & Health
Concerned about EMF exposure? The Specific Absorption Rate (SAR) indicates how much radiation your body absorbs from a phone.
iPhones generally have SAR values around 1.1 W/kg.
Samsung devices often feature slightly lower SAR ratings (~0.8 to 0.9 W/kg).
OnePlus phones follow international safety standards, though values vary by model.
All brands meet global SAR safety limits, but using earbuds, keeping the phone away from your body, and avoiding bedtime usage can reduce long-term exposure.
