That can be confusing when the same charger and cable are still connected. If a charger is advertised for fast charging, why does the final part take so long?</p> <p>The short answer is that charging speed is not meant to stay constant from empty to full. A phone controls how much power its battery receives, and the safe, appropriate rate changes as the battery&rsquo;s state of charge, voltage, and temperature change.</p>
