Why do charging times still feel too long for electric scooters?

[Justin]

You might have noticed when you are charging, battery capacity keeps increasing, but charging speed seems taking a long time. Faster charging is convenient, yet many people think that it could shorten battery lifespan. Would you compromise long-term battery health for significantly faster charging?

My smartphone charges for hours so I am actually used to it. I would not mind the charging time and would not compromise it for long term battery health.
