The ability to cease power delivery to a device’s battery, potentially as a feature within iOS 18, implies a mechanism to interrupt the battery’s charging or discharging cycles. This hypothetical function could be activated through a software setting or hardware control to prevent further energy flow to or from the battery.
This functionality could be important for preserving battery health over extended periods of disuse, mitigating risks associated with overcharging, or preventing battery degradation caused by sustained high temperatures. Historical context suggests that manufacturers have explored various power management strategies to prolong battery lifespan; this feature would represent a direct user-controlled intervention in that process.
