Megan reports her three-year-old company-issued iPhone has become slow when launching apps and switching between them. Battery health is 85 %, the phone is running the latest iOS version, and Wi-Fi connectivity is stable. Settings shows only 1 GB of free space remaining on the 64 GB internal storage. Which action should the technician try first to improve the device's responsiveness?
Turn off Bluetooth and NFC radios to reduce background activity
Perform a factory reset and then restore the latest backup
Offload unused apps and delete large videos to free several gigabytes of storage
Enable Low Power Mode so background tasks are throttled
Mobile devices can become sluggish when internal storage is nearly full because the OS needs free space for virtual memory, caching, and routine maintenance. The quickest, least-intrusive first step is to free storage by offloading unused applications and removing large media files. Disabling radios such as Bluetooth or enabling Low Power Mode may conserve battery but will not address storage-related performance bottlenecks. A factory reset would likely help but is far more disruptive and should be attempted only after simpler measures fail.
