The rollout is slated to begin at 10:00 a.m. Pacific Time (PT) / 1:00 p.m. Eastern Time (ET). Apple’s website for India lists a September 14 launch, while the pages for Singapore, Hong Kong and several other Asian regions list September 15, indicating a narrow release window designed to align with midnight in those locales.

Installation Recommendations
Apple advises users to verify that their iPhone or iPad is fully charged and connected to Wi-Fi before initiating the update. The update can be checked by navigating to Settings -> General -> Software Update; the device will then contact Apple’s servers to confirm availability. Users who prefer a slower rollout may wait until the device is connected to a computer, allowing the update to install at a later time.
Expected Server Load and Possible Delays
Apple notes that the initial distribution of a major iOS release often strains its servers, leading to slower download speeds and temporary sluggishness on devices. Because millions of users may attempt to download the update simultaneously, the surge can overwhelm network capacity. Apple recommends waiting a day or two after the official launch to reduce the risk of download delays and to ensure a smoother upgrade experience.
