Understanding iOS Low Power Mode and How to Automate It

iOS includes a Low Power Mode (also called Power Saving Mode) that, when enabled, extends iPhone and iPad battery life by limiting various system functions and reducing performance.

When Low Power Mode is active, the following features are restricted: background app refresh, auto‑lock timeout reduced to 30 seconds, lower screen brightness, screen refresh rate capped at 60 Hz, reduced dynamic effects, iCloud photo sync paused, app updates and email fetching paused, and on iPhone 12/13 5G is disabled.

In addition to these restrictions, the mode also lowers overall device performance; Geekbench 6 scores show more than a 50 % reduction in both single‑core and multi‑core performance, which helps lower power consumption and extend standby time.

The article also shares a personal use case, describing how the author enables Low Power Mode before trips when charging opportunities are uncertain, and provides instructions for adding the Low Power Mode toggle to the Control Center.

To automate the activation of Low Power Mode, the author outlines a simple Shortcut automation: open the Shortcuts app, create a new automation triggered by battery level, set the desired threshold (e.g., 50 %), select the “Low Power Mode” action, and save the automation. Screenshots illustrate each step.

After setting up the automation, the author reports that their iPad mini’s charging interval increased from two days to four days, demonstrating the practical benefit of the automated low‑power setting.
