Low battery alerts: warned before the map goes dark

The smallest feature with the biggest worry-to-fix ratio

Every parent who has used a family locator knows the specific dread of the frozen pin: the dot that stops updating, the calls that go straight to voicemail, the mind that goes straight to the worst. And in the overwhelming majority of cases, the explanation is the most teenage thing imaginable — the battery died at 23% of the school day remaining, exactly as it has every day this week.

Low battery alerts get ahead of the dread. When a child's phone drops below the threshold you set, your phone gets a quiet heads-up: Liam's phone is at 15%. The alert arrives while the phone is still alive — which means there's still time for the boring, effective interventions: a "charge your phone" text that actually lands, a reminder about the power bank in the front pocket, a pickup plan confirmed now instead of guessed at later.

What the alert changes

• Silence gets context. When the pin does freeze an hour later, you already know why. The difference between "phone died, as warned" and "unreachable, unexplained" is the difference between mild annoyance and a spiral.
• Last known location means more. A dead phone's pin stays on the map with its final timestamp — and because you saw the battery alert, you can read that frozen pin correctly: not missing, just uncharged, last seen at the bus stop at 4:12.
• Plans firm up in time. "Phone's about to die — pickup at the main gate at 5:30, confirm now" is a message that can only be sent before the battery goes. The alert creates that window.
• The habit eventually forms. Several families report the alerts becoming obsolete — the child, tired of the "charge your phone" texts, starts charging at lunch. The feature retires itself. We consider that a five-star outcome.

Small, sensible details

You choose the threshold per child (20% is the popular default — early enough to act, late enough not to nag), and alerts respect the rest of your notification settings, so this stays a whisper, not another source of noise. The battery level is also always visible next to each child's pin on the live map, so the answer to "should I worry about the silence?" is one glance away even between alerts. And the feature pairs naturally with its siblings: a low-battery warning followed by a geofence arrival at home is a complete story — phone nearly dead, kid safely in the kitchen, nothing to do but mention the charger at dinner.

Part of Premium

Low battery alerts ship with Premium — a small feature riding along with location history, unlimited geofences and the rest, and for many parents the one they end up quietly appreciating most.
