If the battery in a smartphone runs out very quickly then it becomes very difficult to do any work. In such a situation, there is a need to charge the phone fast. Nowadays, the phones coming in the market have fast charging support. But even after this the phone charges slowly. The company may not have provided fast charging support to charge the phone, but by keeping the phone on airplane mode, it charges faster.

If the smartphone charges fast then remove the cover of the phone before putting it on charging, this can be beneficial. Before putting the phone on charging, turn off mobile data, WiFi, Bluetooth, GPS location and hotspot.
