iPhone temperature charging: a much needed feature

When Apple introduced the battery health level indicator on the iPhone; This made us very conscious of the 100% fill rate. Many users, including us, are looking for features to keep the battery safe and healthy. If there’s one thing we’ve learned, it’s that high battery temperatures are a major factor in decreasing battery health.

Earlier, Apple used to provide a full-screen warning when your iPhone’s temperature exceeds permissible levels, even while charging. However, with iOS 16, Apple took a step further to suspend iPhone charging without manual intervention when the temperature rises.


This is a much needed feature as it keeps the battery safe and prevents further heating. It also prevents overheating that could potentially damage other internal components of the iPhone.

But why is overheating bad for batteries? Let’s find out.

Lithium Ion Batteries and Overheating.

Lithium-ion batteries are heat resistant. When they are exposed to high temperatures, it affects the chemical reactions within them. The electrolyte in the battery facilitates the movement of ions across the anode and cathode.

However, The electrolyte is quite sensitive to thermal changes, and at high temperatures they can crystallize and block the anodes and cathodes.

This stops them from storing lithium ions. Simply put, excess heat inhibits the normal functioning of the battery. This increases battery life and, when repeated, degrades the battery’s health over time.

Therefore, you must be careful about this. In the next part of the article, let’s understand how to prevent your iPhone from overheating while charging and how to fix the ‘iPhone Charging Paused’ message.
