Many of us use wireless charging to charge our phones. Wireless charging was invented a while ago by Nikola Tesla, an electrical engineer. Wireless charging is easy, simple, and you can quickly throw your phone on a wireless charger to begin charging it. Wireless charging is indeed more simple and easy, but surprisingly, at least to some people, it charges slower than cable charging. Cable charging is faster because it has a direct connection from the energy source, to the phone, charging the battery directly, whereas wireless charging sends low-power signals through the air, creating a delay in charging.
Whether you are charging your smartphone via cable or wireless charging, your battery can get slightly warm. Usually, the battery will become warmer when you are charging via wireless charging and this can cause issues with the battery. The Samsung Galaxy Note 7 was prone to LITERALLY lighting on fire if the battery got slightly too hot. Don't worry, if you have a Galaxy Note 8, 9, 10, etc, you should be fine now. Another disadvantage with wireless charging, you cannot perform it through metal material. For example, if I have a Samsung Galaxy Note 20, sure, I can charge via a wireless charger very easily, but if my phone case is made from a metal material, the wireless chargers low power signals will get disrupted by the metal, causing your phone to not receive any more electric charge.
Plugging in your smartphone via a cable can be more of a "hassle" than simply placing your phone on a wireless charging platform, but cable charging is definitely more powerful and faster than wireless charging, at least for now as of December 14th, 2020.
