For modern smartphones with lithium-ion batteries, it is generally recommended to keep your phone's battery level between 20% and 80% for regular use. This range helps prolong the overall lifespan of the battery and keeps it in a healthier state over time.
Here are some charging tips to consider:
Avoid deep discharge: Try not to let your phone's battery level drop to 0% or completely drain it regularly, as this can put more stress on the battery.
Avoid constant full charging: Frequent charging from very low to 100% can also degrade the battery over time.
Charge when needed: Charge your phone when it's around 20% to 30% and unplug it when it reaches around 80% to 90%.
Occasional full discharge: It is beneficial to perform a full discharge (0% to 100%) once every few months to recalibrate the battery level indicator. However, do not make this a regular habit.
Avoid extreme temperatures: Keep your phone in a temperature range of 20°C to 25°C (68°F to 77°F) for optimal battery health. High temperatures can degrade the battery faster.
Use a quality charger: Use the charger provided by the manufacturer or a reputable third-party charger to avoid any damage to your phone's battery.
Remember that modern smartphones often have built-in mechanisms to help protect the battery, so it's not necessary to be overly concerned about charging your phone occasionally to 100% or letting it drop slightly below 20%. The key is to avoid frequent and prolonged exposure to extreme low or high battery levels. Ultimately, if you find it more convenient to charge your phone overnight or to 100%, it won't drastically affect the battery lifespan, but adhering to the 20% to 80% range will maximize its longevity.
