Smartphones have replaced the need for many tools and gadgets and become an integral part of the modern lifestyle. But some habits are known to compromise their efficiency. Charging a smartphone, for instance, may appear to be a straightforward process, but how it is done significantly influences the battery lifespan, impact on electricity costs, and user safety. Here are some common charging mistakes that one should avoid to ensure the efficiency of the device. Leaving the charger plugged into the socket When a charger sits in the socket, it continuously consumes power, leading to increased electricity bills. Additionally, the heat emission from the transformer increases the risk of electrical fires, especially in humid air. To mitigate this, users should unplug chargers when not in use. Charging the battery to maximum capacity Smartphone batteries, especially lithium-ion and lithium-polymer, come with a set number of charge cycles. Consistently charging them to 100% tends to shorten their lifespan. It’s recommended to keep the battery charge percentage between 20% and 80% to expand lifespan. Draining the battery fully before charging again Similarly, regularly letting the battery reach zero before charging can lead to unnecessary strain on the battery and slowly result in a shorter lifespan.
