Battery Warning doesn't need to be pinned to the toolbar or stay visible — it runs quietly in the background on every page once your access above is active. Clicking its icon (from the toolbar or the puzzle-piece Extensions menu) always opens this settings page.
Every 2 minutes, on the exact even-minute mark of your system clock (for example 10:00, 10:02, 10:04), Battery Warning checks your device's battery.
A warning is shown only when all of these are true:
Battery is at 20% or lower.
The device is not currently charging.
The battery level is not increasing (a rising level suppresses the warning even below 20%).
When a warning fires:
A bold percentage appears in the upper-right corner of the current page for 10 seconds, blinking to draw attention.
Its color shifts with severity — green near 20%, yellow around 15%, red at 7% and below.
A series of short audio "tinks" plays at the same time — 1 tink at 20%, scaling up to 5 quick tinks at 5% or below.
Plugging in to charge, or the battery level ticking back up, silences the warning on the very next check — nothing to click or dismiss.
The Battery Warning Access card above shows whether you're on a free trial or a paid subscription, and lets you subscribe, start a trial, log in to an existing account, or refresh your access status.
