What is SAR? Why Should I Check It in My Refurbished Phone?

SAR stands for Specific Absorption Rate. It is a measure used to quantify the amount of radio frequency RF energy absorbed by the body when using a wireless device, like a mobile phone. This metric is crucial because it helps gauge how much electromagnetic energy your body is exposed to during phone use. Understanding SAR is particularly important when you're considering buying a refurbished phone, as it ensures the device remains safe and within regulatory standards even after repairs or modifications.
