Smartphones always have a common weakness—limited battery life. That's why many users choose to charge their phones overnight to save waiting time. But is charging overnight really beneficial? Read on for information we provide below to find the most scientific solution for phone charging.
Is Overnight Phone Charging Beneficial or Harmful? Pros and Cons
Is Overnight Phone Charging a Good Idea?
In reality, most users believe that charging their phones overnight is the most suitable time because they are not actively using them. Waking up to a fully charged device for a new workday seems practical. However, this mindset, along with consistently keeping the phone at 100%, can shorten the battery lifespan. And this is indeed one of the common mistakes in smartphone charging that we've shared before.
Although most smartphones today are equipped with Lithium-ion (Li-ion) batteries and modern chargers designed to cut off power once the battery reaches 100%, overnight charging is not ideal. Lithium-ion batteries are sensitive to significant changes in state and temperature. Charging overnight will keep the phone maintaining a small charging current to top off whenever the battery drops a percentage. This continuous small current can lead to instability and potential risks of explosion or danger for users if the battery is overcharged or depleted.
Mytour's advice for you is to use the phone at a moderate battery level, then charge it for a short period to have enough battery capacity for usage. It's better than charging to full and using until the battery is completely depleted. If there's a need to charge the phone overnight, use chargers and cables provided by the manufacturer to ensure the highest safety. Avoid consistently keeping your smartphone's energy level at 100%. The best practice is to charge when the phone notifies and try to unplug as soon as the battery is full.
Additionally, it's advisable to keep your phone in a cool environment as high temperatures also have a negative impact on the device's battery. Generally, noticeable battery degradation usually occurs within 1 to 2 years after purchasing a phone. So, if you're someone who frequently upgrades your phone, you don't need to worry too much about whether or not to charge your phone overnight. On the contrary, if you want to prolong your phone's lifespan, avoiding overnight charging is recommended for more efficient battery longevity. And if your phone usage is urgent, check out some tips for fast charging your phone that we've previously shared to ensure it doesn't interfere with your current tasks.
