According to smartphone manufacturers’ recommendations, it is not advisable to regularly charge overnight as this can affect the battery life. Users should only charge their phones until the device shows full or near-full battery and then disconnect the charger.
Battery life depends not only on the assembly time but also on several other factors, including high temperature fluctuations and charging habits. The lithium-ion batteries in our phones chemically age and charge less over time. That’s why old phones don’t hold a charge for long.
Many people wonder if charging their phones overnight is recommended.
The phone’s battery will automatically stop charging when it is full, but in some cases, when the battery drops to 99%, it will require more energy to reach 100% again. This constant cycle will deplete the battery life. Most phones come with charging options for this reason.
The correct way to charge your phone overnight
Many smartphones now have built-in battery charging time control features, making overnight charging safer.
Starting from iOS 13, Apple has also added the Optimized Battery Charging feature. This feature analyzes charging habits and waits until the charging process reaches 80% before completing it as needed by the user.
To activate this feature, first, open the Settings menu, then select Battery and choose Battery Health. Finally, select “Optimized Battery Charging” to finish.
Many smartphones now have a feature for controlling battery charging.
Not only Apple, but current Android devices also have this feature. Various Android manufacturers offer more options with specific battery control functions for each device line.
To set up this feature on Android, first, open the Settings menu, then select Battery Management to activate it.
In case there is no such feature, users can find support applications like AccuBattery for Android, which allows users to monitor their battery status and know when to charge and when to unplug to maximize battery life.
However, according to experts, maintaining the smartphone battery to achieve the highest lifespan depends on users’ usage habits. You no longer need to wait until the battery drops to below 20% as before, but you can charge it anytime. However, it is advisable to limit overnight charging multiple times.
In addition, it is not recommended to place your phone near hot environments like under the sun or heat sources as it will accelerate battery aging.
