How to fast charge the latest iPhone and iPad

In the never-ending race of technology, battery charging speed is becoming one of the competitive factors between phone manufacturers. Starting with the iPhone 8, Apple has added a fast charging mode to the iPhone, allowing users to charge 50% of the battery capacity in just 30 minutes. However, things do not always work as advertised, because it depends on many factors.

What is fast charging?

Fast charging is a technology that allows you to charge your phone battery at a significantly higher speed than normal charging. The trick is to use a charger with a higher capacity, which allows you to transfer energy to the battery faster. However, it should be noted that each device has its own charging capacity limit, and using a charger that is too powerful will not only not increase the charging speed but can also damage the battery and even damage the device.

Benefits of fast charging

Fast charging brings many practical benefits, helping to improve user experience and meet the increasing demand for mobile devices:

- Save time: Fast charging significantly reduces charging time, allowing you to quickly use your device again without having to wait long. This is especially useful for people who travel frequently, work on business trips or have a tight schedule.

- Increased flexibility and convenience: Fast charging will help you not depend on power outlets, convenient for moving and using in many different situations, from working at a coffee shop to traveling and exploring.
