Throttling During Long UK Commutes – Causes and Prevention Understanding Performance Throttling on Commuting Devices During extended commutes on UK transport networks, both iPhone and Samsung devices are prone to throttling, where system performance is temporarily reduced. This can occur on trains, buses, and while cycling through areas with fluctuating mobile coverage. Throttling is primarily a protective mechanism, triggered by thermal load, battery management, and resource-intensive tasks during long periods of active device use. Primary Causes of Throttling During UK Commutes 1. Thermal Stress Devices heat up during prolonged use, particularly when multiple apps are active, screens remain on, and mobile data is heavily utilised. Observations indicate that temperatures above 35°C internal can trigger automatic CPU throttling to prevent hardware damage. 2. Battery Management Low battery levels combined with high CPU load cause the system to reduce processing speed. iPho...
