It is essential to use the correct charging methods for your iPhone to maintain its battery health. Your iPhone’s battery is designed to last for a certain number of charging cycles, which is the number of times the battery can be fully discharged and charged before it begins to degrade.

One common misconception about iPhone batteries is that you should let them drain completely before charging them. However, this differs from modern lithium-ion batteries used in most smartphones, including iPhones. Letting your battery drain ultimately can harm its health and may reduce its lifespan.

Another common mistake is using a cheap or counterfeit charger that needs to be approved by Apple. These chargers may need to provide the proper voltage or amperage to your iPhone, which can cause your battery to degrade faster. Additionally, using a non-Apple charger may void your iPhone’s warranty.

Using wireless charging may also affect your iPhone’s battery health. While it is convenient to place your iPhone on a charging pad, it can cause your battery to heat up, which can degrade its lifespan over time. Using wired charging methods to minimize heat generation and protect your battery health is best.
