Two lightning symbols indicate fast charging. The number of lightning ICONS represents the charging speed of the phone. If there is a lightning bolt, it is a normal charging state. When there are two lightning flashes, it means fast charging. Three lightning flashes, it's a super fast charge. How much lightning appears, on the one hand, depends on the mobile phone, when the mobile phone supports fast charging, it can automatically switch to the fast charging state.
On the other hand, if the phone supports super fast charging, you also need to use the original charging adapter and data cable. Whether fast charge is supported can be judged from the power adapter of the phone. For example, on the charger of Huawei mobile phone, if it shows quick charge, it is fast charging. At the same time, the output power of the charger can also be passed. If the super fast charge is used, the output power is 3, and the fast charge is 2. It is usually 5V\/2A or 9V\/2A.
Take Huawei P40 of EMUI11 system as an example, Huawei mobile phone shows two lightning flashes when charging, indicating that the mobile phone has entered the super fast charging mode, that is, the user's mobile phone supports Huawei's super fast charging technology, and the same battery capacity, the mobile phone that supports fast charging is faster than the model that does not support fast charging
