Should I charge my phone overnight?

VTC NewsVTC News04/03/2023


According to smartphone manufacturers, you should not keep the habit of charging overnight regularly because this can affect battery life. Users should only charge the phone until the device shows full or almost full battery, then disconnect the charger.

Battery life depends not only on when it was assembled, but also on a number of other factors, including extreme temperature fluctuations and charging habits. The lithium-ion batteries in our phones chemically age and hold less charge over time. That’s why older phones don’t hold a charge for as long.

Should you charge your phone overnight is a common question for many people.

Your phone's battery will automatically stop charging when it's full, but in some cases, when the battery drops to 99%, it will need more power to get back to 100%. This constant cycle will drain the battery's life. Most phones come with regulated charging options for this reason.

How to properly charge your phone overnight

Many smartphones now have built-in battery charging time control features, making overnight charging safer.

From iOS 13 onwards, Apple has also added the Optimized Battery Charging function. Accordingly, after being enabled, this function will analyze charging habits and wait for the 80% charging process to finish until the user needs it.

To enable this overnight phone charging feature, first open Settings, then select Battery and select Battery Health . Finally, select “Optimized battery charging” and you’re done.

Many smartphones today have built-in battery charging control features.

Not only Apple, Android devices are now also updating this new feature. Accordingly, Android manufacturers also offer more options with certain battery control functions on each device line.

To install this feature on Android, first open Settings , then select Battery Management to activate it.

In the absence of such a feature, users can find supporting applications such as AccuBattery for Android, which allows users to monitor their battery status, thereby knowing when to charge and when to unplug to maximize battery life.

However, according to experts, keeping your smartphone battery at its longest lifespan depends on your usage habits. You no longer need to wait until the battery is below 20% like before, but can charge it at any time. However, you should limit overnight charging many times.

In addition, you should not leave your phone near hot environments such as under the sun or heat sources because the battery life will decrease faster.
