Experts Issue Urgent Warning for Users Who Charge Phones to 100 Percent
The long-standing question of smartphone users, 'Should I charge my phone to 100%?' is finally being answered with scientific facts. Experts and tech giants are emphasizing the necessity of limiting the phone's charge to 80% in order to prolong battery life.
The operating principle of Lithium-ion (Li-ion) batteries used in smartphones is likened to the water-holding capacity of a sponge.
Just as a completely dry sponge becomes rigid, a sponge fully saturated with water is under heavy pressure.
The same principle applies to batteries: The optimal level for battery health is between 20% and 80%. Within this range, lithium ions move without stress. Forcing the charge from 80% to 100% equates to higher voltage and temperature. This situation accelerates the chemical aging of the battery, gradually reducing its capacity over time.
It's not just the charge percentage that matters, high temperature too plays a significant role in rapidly depleting the battery life.
Experts offer the following advice to maintain battery health:
Avoid gaming while charging: The simultaneous heating of both the processor and the battery creates a 'double heat' effect.
Be mindful of cases: Thick cases trap heat. Removing the phone from its case during charging allows the battery to breathe.
Alignment in wireless charging: Incorrect placement of the phone on the charging pad can result in power being converted into heat.
The habit of completely draining the charge from old nickel batteries before recharging them is actually detrimental for modern Li-ion batteries.
In today's technology, charging your phone intermittently throughout the day (between 40% and 70%) is much healthier than completely draining and recharging it.
In essence, rather than leaving your phone at 100% full and under high voltage overnight, activating the 'battery protection' settings offered by your device could potentially extend its high performance use by a few more years. Particularly during travels, using smart portable chargers equipped with temperature control (XCooling technology) provides extra protection against external factors.
