A1: Yes, slight heating is normal. The WiFi 6 chip and signal amplifier generate heat during operation, especially in high-speed transmission (downloading, 4K viewing). The surface temperature (≤50℃) is safe and won’t affect service life. Avoid closed spaces, keep ventilation, and do not use it under high load for a long time.
