Apple’s iPhones, despite being premium devices, come with built-in features that warn users before major problems arise—especially related to battery health. However, around 90% of iPhone users miss these signals due to lack of awareness. One key indicator is the battery draining quickly and needing frequent charging, which does not happen suddenly but is preceded by subtle warnings within the phone.

A vital tool to monitor is the Battery Health and Charging section found in iPhone Settings under Battery. This feature provides real-time information about the battery’s current capacity and health status. When the device is new, the battery health shows 100%, but as it ages and undergoes charging cycles, the capacity diminishes. Once the battery health drops to around 80% or below, it’s a clear sign that the battery is deteriorating and should be replaced soon to avoid sudden shutdowns or poor performance.

Battery health also significantly impacts the resale value of an iPhone. Prospective buyers often check this metric, and devices with battery health under 80% typically fetch a lower price because they will require battery replacement sooner.

To prolong battery life and maintain good battery health, users are advised to follow a simple charging rule: keep the battery charge level between 20% and 80%. Avoid letting it drop below 20% or charging it all the way to 100% regularly. Adhering to this guideline can help maintain battery capacity and extend the overall lifespan of the iPhone’s battery.

In conclusion, iPhone users should regularly check the Battery Health feature and adopt mindful charging habits to avoid unexpected breakdowns and protect their device’s value. Recognizing these early hints can save both money and hassle in the long run.
