What is Battery Monitor?

Battery Monitor is a lightweight browser-based utility that tracks your device battery level, AC charging status, estimated time until full charge, and remaining discharge time via the standard W3C Battery Status API.

Designed for laptops, tablets, and smartphones, it provides a clean visual indicator of battery health without requiring background processes or third-party diagnostic software.

For browsers with restricted battery telemetry APIs, Battery Monitor provides transparent fallback status cards to protect user privacy while offering reliable hardware information.

Privacy Guarantee: Battery status data is queried locally from browser navigator objects. Zero device telemetry or battery metrics are collected or shared.

Frequently Asked Questions

Does this tool monitor battery status in real time?
Yes! Attaches event listeners to levelchange and chargingchange events, updating battery cards instantly when power cables are connected or disconnected.
Why does Firefox or Safari show a privacy fallback message?
Firefox and Safari restrict the Battery Status API by default to prevent fingerprinting tracking. On supported Chromium browsers (Chrome, Edge, Opera), full metrics are available.
How is charging time and discharging time calculated?
Charging and discharging times are reported directly by OS power management APIs via navigator.getBattery(), providing estimated minutes remaining.
Will keeping this webpage open drain my battery?
No! The tool uses zero-bloat vanilla JavaScript with passive event listeners, consuming less than 0.1% CPU resources.
Is any battery health or hardware serial data collected?
No! We strictly query standard battery percentage and charging state locally in memory.
