It sounds alarming to experience a shock when touching your iPhone 16’s new camera button while also touching a grounded object like a radiator or metal bed frame. What you’re feeling is most likely not a dangerous “electric shock,” but a mild electrostatic discharge (ESD) or a leakage current sensation caused by how modern electronics are built. When you touch the phone and then touch a grounded surface, you may complete a path for tiny residual currents or static electricity to dissipate. This can feel like a “zap” or “tingle,” especially in dry environments or when you’re barefoot.
This phenomenon is generally harmless, but if the shock feels strong or unusual, or if you notice visible damage to the phone or charger, you should have it checked at an Apple Authorized Service Provider for safety.
