1. Using Damaged iPhone Charging Cords

Have you ever had an iPhone charging cord that you've held onto for a long time, even though it's been a little beaten up or damaged in some way? It's understandable not to want to replace a charging cord right away, especially if it still has the little charging bolt popping up on your battery icon. However, just because the cord is able to charge your phone doesn't mean it's doing a good job.

 

Using damaged cords to charge your phone can be extremely harmful to your device, as they can result in sending unstable power levels to your smartphone. They can also be risky and create a fire hazard in your home without you even realizing it.

2. Charging Your Phone In A Hot Environment

Sometimes, many of us forget that temperature has a bigger impact on our devices than we may think. Heat is notorious for messing with the function of iPhones, which is why during a hot summer day or sunny afternoon on the beach, you may get a notification from your device, a push notification letting you know it needs to cool down.

 

When you charge your iPhone in a super hot environment, like on the dashboard of your car during a hot, sunny drive, or while it's sitting out in the sun in general. It can accelerate the breakdown and aging of the lithium-ion battery in your device, potentially causing irreparable damage.

 

While no one is perfect, and with a super busy schedule, it can be challenging to maintain pristine charging habits that protect your device. However, avoiding these two dangerous mistakes can save your device and keep it healthy for years to come.
