Smartphones can be damaged by common habits that many people are unaware of, as warned by experts in materials science and electronics.
Charging mistakes like leaving the phone at full charge or letting it fall below 5% can degrade the battery materials and reduce capacity.
Fast charging generates heat that can damage the battery's protective layers, making it dangerous and shortening its lifespan.
Extreme temperatures, physical damage from drops, using poor-quality chargers, and other harmful habits like ignoring software updates or carrying the phone with keys can also harm the device over time.
