Usually, the time shown on the fast charge is not the time it takes to actually charge, but an estimate. This is because the fast charge technology will charge the battery at a higher current when the battery is low to quickly increase the charge. However, as the battery power increases, the charging speed will gradually decrease to ensure the safety of the charging process and battery life.

So when your device says it takes six hours to fully charge, it may actually get the amount of power you need in less time. This time estimate is calculated based on factors such as the device's battery capacity, current charge, and the power of the charger.

Reason analysis: If you are charging with the original charger and data cable, it shows that it should be full for 6 hours, which is a little abnormal, your mobile phone can be charged to 45% of the electricity with the cable fast charge for 30 minutes, and can be full for about an hour, and the slow charge can be full for about 3 hours. If you use wireless charging, you need to see the power of the wireless charging seat. It could take more than six hours to fully charge.
Because the capacity of the battery is very large, even the fast charge needs to be charged for 6 hours.
