Apple has shared guidance on how users can speed up their iPhone devices following system slowdowns caused by installing new iOS software.
Recommendations from company specialists were cited by technology publication 9to5Mac, outlining steps to help users navigate post-update background tasks without major disruption.

According to Apple, installing a fresh version of iOS triggers an automatic indexing process across the device. During this background operation, the smartphone systematically scans, re-organizes, and updates all data stored in the memory of the device.
Apple acknowledged that this indexing process can stretch on for hours or even days depending on the volume of stored data. While indexing is active, the device may operate noticeably slower and consume battery power at an elevated rate.
Methods to speed up indexing
Representatives from the technology giant revealed that the secret to enduring the indexing process smoothly is to connect the smartphone to a charger and establish a stable Wi-Fi network connection. Furthermore, Apple recommended setting the gadget aside and refraining from using it for a period immediately after the update finishes.
The indexing routine is not exclusive to smartphones. Apple noted that the process also launches after installing updates on macOS, iPadOS, and other Apple operating systems. Because of this, the same maintenance recommendations apply to other gadgets across the American brand's hardware lineup.
Background system processes
System indexing is a standard background feature in modern operating systems. When new software is installed, indexing helps rebuild databases for on-device search tools, photo categorisation, and file management. iOS powers Apple's iPhone lineup, while macOS runs on Mac desktop and laptop computers, and iPadOS operates on iPad tablets.

Upcoming product announcements
The technical guidance follows Apple's previous announcement of a major product presentation scheduled for September 9.
The company is expected to present its next-generation smartphones at the event, including the iPhone 18 Pro and the iPhone 18 Pro Max. Reports also indicate that Apple will showcase its first foldable smartphone, named the iPhone Ultra.
