Rumors suggest Apple's upcoming foldable iPhone will be noticeably heavier than a standard iPhone, prompting concerns from a physical therapist that the added weight and grip could increase thumb and hand strain during prolonged use. Similar complaints have already been reported by some owners of existing foldable phones, though the risk is mainly associated with repetitive, extended use. Experts recommend taking breaks every 30–45 minutes, stretching your hands, and putting the phone down regularly to reduce fatigue and injury.
