Automatic Charging Speed Test Online

No manual battery percentage entry. This test reads the battery information your browser permits and observes actual percentage changes while plugged in.

How it works: Connect your charger, then tap Start. Leave the page open. Once the battery percentage increases, PhonePakka calculates percent gained per hour based on the time observed. A single 1% increase can give an unstable estimate; longer observations are better.

This is a percentage-based estimate, not actual charging wattage or battery health. Battery percentage can update slowly; keep this page open while plugged in.
