Many users still follow outdated charging routines, but experts highlight how these habits can accelerate lithium-ion battery aging, emphasising better practices for longevity.
Many smartphone owners still follow habits suited to older batteries, but experts say those routines can quietly shorten the life of modern lithium-ion cells. The most common mistake is letting the battery run all the way down before plugging it in, then charging it straight back to 100%. According to technology guides and battery specialists, both extremes increase wear over time.
The better approach is to keep the charge level in the middle range, roughly between 20% and 80%. Reports from Kompas and battery-care guides say partial charging places less stress on the cell than repeated full drains and full top-ups. TechRadar has also reported that charging to 100% is not dangerous in itself, but doing so all the time can speed up ageing.
Charging equipment matters as well. Experts recommend using the original charger or a reputable replacement, and checking cables regularly for damage. They also warn against heat, which can be one of the biggest threats to battery health. Leaving a phone in direct sunlight or covering it while it charges can raise temperatures and reduce capacity more quickly.
For people who charge overnight, many manufacturers now offer smart charging features that slow the process and finish topping up the battery just before the owner usually wakes. Battery analysts say this can help reduce the time the phone spends sitting at a full charge. Modern lithium-ion batteries also use charging stages designed to limit stress, but good habits still make a difference over the long term.
