Voltage pressure and temperature
The report explained that keeping the battery at a 100% charge level for long periods causes stress on the voltage of the positive electrode and the electrolyte. Although modern phones use “intermittent charging,” the greatest danger lies in the heat resulting from remaining on the charger, especially if the phone is under a pillow or running heavy applications, which accelerates internal chemical corrosion.
Practices that accelerate spoilage
Experts pointed to several factors that exacerbate the damage, including:
Charging under direct sunlight or in high temperature places.
Use the phone for gaming or video editing while charging.
Relying on cheap, uncertified cables and adapters that provide unstable current.
Tips for preserving the battery
To extend battery life, it is recommended to follow these steps:
Activate smart features: such as “Enhanced Charging” in iPhone, or “Battery Protection” in Samsung, which slows down charging at night.
Keep cool: Charge the phone in a well-ventilated area and remove the cover if it gets hot.
Avoid wireless chargers at night: they trap heat more.
Short Charges: Lithium batteries prefer frequent charging for short periods rather than long full cycles (0 to 100%).
The report concluded that batteries perform best at temperatures between 16 and 22 degrees Celsius, stressing the importance of using original accessories to ensure current stability and protect battery cells in the long term.
