Apple’s Battery Optimization Feature

Apple has played its part in ensuring better battery longevity. In a recent update, Apple introduced a feature that initially charges the phone up to 80% rapidly and then gradually reaches 100%. This method reduces stress on the battery, preventing rapid degradation that might occur from fast charging to 100%.

Factors That Do Affect Battery Health on your iPhone:

While charging overnight might not be the main culprit behind battery degradation, other factors can impact your iPhone’s battery health significantly:

  1. Extreme Temperatures: Avoid exposing your iPhone to extremely hot or cold conditions, as this can accelerate battery ageing. Extreme temperatures can cause chemical reactions within the battery that contribute to faster degradation.
