There are common mistakes when using or charging an iPhone, such as charging it overnight or even using it while connected to power. However, lithium-ion battery specialists and the Apple company itself agree that the biggest enemy is overheating.

Excess temperature accelerates the chemical deterioration of these batteries, reducing their capacity to store energy over the months, notes Apple's official website. In this sense, some daily habits can shorten their useful life much faster than expected.

The error that damages the iPhone battery the most

The worst mistake is using your iPhone for high-performance tasks while it remains connected to the charger. Playing video games, using GPS navigation applications during long journeys, editing videos or running heavy processes causes the processor to work harder and generate more heat.

Added to this is another common habit: leaving the phone charging on a bed, a sofa, a pillow or any surface that makes ventilation difficult. These materials retain heat and prevent the device from dissipating it properly, raising its temperature even further.

When your iPhone gets too hot while charging, the battery ages faster and may lose capacity sooner than expected, resulting in shorter daily battery life and more frequent battery replacement.

And a very serious mistake that should be mentioned is using low-quality or uncertified chargers or cables. Uncertified accessories can provide unstable power supply, affect the charging process, and even damage both the port and the device's battery.

It is also advisable to prevent the battery from constantly reaching 0% or keeping it at 100% for long periods. Lithium-ion batteries tend to maintain their health better when working in intermediate charge ranges.

An iPhone battery is designed to last several years, but its performance depends largely on usage habits. Avoiding overheating, using certified chargers and maintaining proper charging cycles can help maintain better autonomy for longer.
