Should you leave the charger plugged into the outlet continuously when not in use?

Is it okay to keep the charger plugged into the socket continuously?

Even when not charging, it still consumes electricity

Chargers are designed to operate on the principle of a transformer: converting high voltage to low voltage, changing the current from alternating to direct to charge the phone.

The structure of a charger includes two main components: primary and secondary. The primary is connected to the input current, and the secondary is connected to the output current. Therefore, whether the output circuit is closed or not (meaning whether it is charging or not), the input circuit is always closed if plugged in.

Does plugging in the charger without charging consume electricity? According to the above principle, even if you are not charging your phone, it still consumes electricity, although not as much as when you are charging your phone.

According to calculations, a basic family (consisting of multiple generations) can save nearly 900,000 VND/year if they ensure the charger is unplugged when not in use.

Easily leads to risks when continuously plugging in the phone charger

In reality, you might think: saving some money cannot compare to the convenience of leaving the charger plugged in and charging whenever you need. However, continuously plugging the charger into the socket will cause the charger to age, becoming a hazard that can lead to fire and explosion risks, as experts have warned.

Especially in households with young children, kids might wet the charger head or put it in their mouths, potentially leading to unfortunate accidents. At this point, remember the many tragic accidents that have occurred, primarily caused by phone chargers.

Protect the environment

Besides ensuring safety and benefits for yourself, consider the environmental impact of leaving chargers plugged in every day. Thousands of chargers left plugged in continuously each year waste millions of kWh annually, with each kWh equivalent to a certain amount of CO2 emissions into the environment each year, directly affecting the living environment around you.

Therefore, the advice we want to give you is: Build the habit of unplugging the charger when not in use!

For more ease and convenience, you can choose sockets with switches to turn off when not in use.

How to charge the battery correctly

Do not charge the phone overnight

Charging the phone overnight can easily damage the battery, not to mention the risk of fire and explosion while sleeping. Therefore, give up the habit of charging the phone overnight.

Do not let the device run out of battery before charging

If you want to maintain the durability and lifespan of the battery, try to avoid letting the device run out of power before charging. Try to charge the battery when the device notifies you to do so.

Do not use the device while charging.

You may have heard a lot about accidents involving explosions due to using the phone while charging. However, advice is never redundant. Don’t let temporary convenience lead to unfortunate incidents.

Use an official charger.

Don’t hesitate to invest in a quality official charger. It ensures safety and effective battery charging. Therefore, equip your beloved phone with an official charger that is compatible with your phone.

Place the phone in a cool place when charging.

Do not charge the battery in high-temperature areas or under direct sunlight, as the phone will generate heat while charging. Therefore, placing the phone in a high-temperature area will affect the battery quality. You can also remove the phone case while charging to help the device dissipate heat better.

Charge the battery multiple times a day.

You can charge the battery whenever you have free time, even if it’s just for a few minutes. This will not affect the battery quality.

Some battery-saving tips

– Turn off Bluetooth, Wi-Fi, 3G, and location services when not in use, as they consume a lot of battery.

– Set the screen brightness to a reasonable level. Usually, you only need to set it to medium or lower, or use auto mode, and the phone will automatically adjust the brightness accordingly.

– Set the screen to automatically lock after 30 seconds to 1 minute.

– Turn off background apps when not in use, such as games, web browsers, and applications.
