Low Battery System Alert

Design the iOS-style low battery system alert that appears when the device crosses the low battery threshold. It should feel like a system interruption, not an app prompt.

The modal needs to show the current battery percentage clearly, explain that power is low, and offer Low Power Mode as the main action. Keep the language short and system-like.

This lives above whatever the user is doing, so the hierarchy has to work fast: percentage, warning, then actions. It should read instantly even on a small phone screen.

Treat it as a native mobile alert with the usual system constraints: centered modal, dimmed background, and a limited action set. The design should feel calm, firm, and familiar.

Make the percentage the anchor of the message; users should know how urgent it is before they read the body copy.
