Does Wireless Charging Ruin Your iPhone’s Battery Health?

Wireless charging has been around for several years and has gained more and more popularity. Most premium and upper mid-range smartphones have wireless charging capabilities, allowing you to keep your battery juiced up throughout the day. If you are investing in the latest refurbished iPhone, chances are you are also looking to purchase a wireless charger.

Wireless chargers are available in various designs and sizes. They are practical, quick, and simple to use. You simply place your phone on a wireless charging dock, and it begins charging as soon as it comes in contact. But, as convenient as this sounds, should you worry about wireless charging affecting your smartphone’s battery health? First, we need to understand how wired and wireless charging work, and then we would be able to find a conclusive answer.

 

 

How do Wired and Wireless Charging Work?

The most common way of charging is by wire. A cable is plugged into the charging device in wired charging and power is transferred from there. The charger typically consists of a charging adapter that goes into an outlet and a cable (copper wires inside) that connects to the device. Of course, you'll need a different sort of cable depending on the device you're charging. For example, most Android smartphones have a USB, C, C to C and micro-USB connector, whereas iPhones have a USB to Lightning cable or C to Lightning cable.

Wireless charging transfers power between your iPhone’s battery and a charger using magnetic fields. Inductive charging is the most widespread method of wireless charging. The inductive chargers emit magnetic fields that cause a current to flow through the receiving device. This current is responsible for charging the battery. Wireless chargers exist in various shapes and sizes, but all operate on the same theory.

Does Wireless Charging Damage Your Device’s Battery?

Wireless charging doesn't damage your phone’s battery. This is a common misconception many people have, but simply not true. However, it's true to some extent that wireless charging generates more heat than wired charging, which can place your battery under more strain because of how it works.  

Thankfully, wireless charging standards like Qi have strict guidelines for managing the heat produced by wireless charging. First, any Qi-certified wireless charger must regulate the charging speed to control heat.  Lower energy output equals lower heat, so your device’s battery is safe. Second, the battery itself doesn't heat up during wired or wireless charging. Only the copper coil inside the phone heats up, and the mobiles have a thermal isolation layer. 

In short, wireless chargers are okay for your phone.

Best Ways to Preserve Your iPhone’s Battery Health

 However, you can develop certain habits to make the battery last longer and protect your iPhone battery from damage.

  • Keep your iPhone's battery between 20% and 80%
  • Do not let the battery drop to zero frequently
  • Avoid keeping the phone plugged in overnight or when the battery's full
  • Invest in good-quality charging pads, cables, and adapters
  • Don't keep your phone on the pad at all times (If charging wirelessly)
  • Try to minimise fast charging use

Do all the above, and your smartphone battery will last longer, and when the next time your battery is low. This way you won’t have to worry about deciding between wireless and wired charging.
