I used the 'Plus Five' rule to fix my iPhone's slow wireless charging - here's how it works

Wireless charging for iPhones can often be slower than expected due to the use of incompatible or low-quality cables and power adapters. A practical method known as the "Plus Five" rule helps optimize charging speed by ensuring the wireless charger is paired with a wall adapter that provides at least 5 watts more power than the charger's rated output. For example, a 15W wireless charging pad should be connected to a 20W or higher wall adapter to maximize efficiency and reduce charging times. Wireless charging technology, while convenient for reducing cable clutter and enabling simultaneous charging of multiple devices, is inherently less efficient than wired charging. Power loss occurs due to heat generation and magnetic field leakage during the charging process. Using the original or certified accessories designed for the charger is crucial, as uncertified or low-wattage adapters can significantly slow down charging speeds or even pose safety risks. Investing in a quality wall brick with sufficient wattage ensures that the wireless charger can deliver power effectively. The "Plus Five" rule is a simple yet effective guideline for consumers looking to improve their wireless charging experience without needing to upgrade the entire charging setup. This approach highlights the importance of matching or exceeding the charger's power requirements with the wall adapter to avoid bottlenecks. It also underscores the broader issue of accessory compatibility in wireless charging, which can impact device performance and user satisfaction. As wireless charging becomes more common in daily tech use, understanding these nuances is essential for users to get the most out of their devices. Proper charging gear not only speeds up the process but also enhances safety and device longevity, making it a worthwhile consideration for anyone relying on wireless power solutions.
