Tyler Morgan, a former Apple Store employee, said the habit of charging an iPhone to 100% is a common mistake. According to him, the lithium-ion battery in the iPhone will age faster if it is continuously fully charged.
Morgan recommends users only charge to about 80% to prolong battery life. He also suggests turning on “Optimized Battery Charging” to reduce battery degradation over time.
Additionally, turning off Bluetooth, reducing brightness, disabling Siri, and limiting background apps also helps save energy. Morgan emphasizes that charging your iPhone overnight is a habit that needs to be eliminated immediately. According to experts, lithium-ion batteries are affected by temperature, charging method and usage time.
For better optimization, users should turn off "Location Services" when not needed to both ensure security and save battery. Dear readers, please watch more videos : Iris scanning tool to verify human | VTV24
