+ * The `navigator.getBattery()` reports the state of the battery and can be
+ * misused to fingerprint users for a short term. The API was removed from
+ * Firefox, but is still supported in browsers derived from Chromium.
+ * The wrapper mimics Firefox behaviour.
+ *
+ * \see <https://lukaszolejnik.com/battery>
+ *
+ * \bug Because we mimic Firefox behaviour, a Chromium derived browser
+ * becomes more easily fingerprintable. This can be fixed by properly
+ * wrapping `BatteryManager.prototype` getters and setters.
