Yes, in general, you can charge your phone on the plane. Modern airplanes often have power outlets or USB ports at the seats where you can charge your phone or other electronic devices. This can be handy during long flights to ensure your phone has enough battery life.

However, it's important to note that not all planes have power outlets or USB ports, and even if they are available, specifications may vary depending on the airline and type of aircraft. Therefore, it's wise to consult the airline's website or contact customer service before your flight to check if charging options are available on your specific flight.
