Should I charge my phone overnight?

“Should I charge my phone overnight?” is always a question of interest and controversy among users.

Antonio Villas-Boas, technology reporter for Business Insider, said that plugging in the phone charger overnight or continuing to charge it for many hours after the device reaches 100% battery level, will cause the aging process of the lithium-ion battery of the device. smartphones are accelerated.

In the opinion of Dominik Schulte – director of a technology consulting firm BatterieIngenieure based in Germany, battery life will be negatively affected if you charge your phone to 100% and keep it plugged in. Or charge overnight. To avoid plugging in the charger overnight when the battery is full, users should charge the phone in the morning or another time.

Will the aging process of the battery be accelerated when the battery is full?

All lithium-ion batteries have a limited lifespan, and their capacity degrades over time. No matter what you do, you can’t change this, but you can make the process faster or slower.

According to Antonio Villas-Boas, when a battery ages, its internal chemical composition will change and negatively affect its ability to store and supply power to the device. Smartphone manufacturers know about this but do not care about users plugging in the charger for too long because they think this does not cause problems. The problem of overnight charging is mentioned by Apple, but the technology company does not say that this action is harmful.

However, Ronald Ho, a project manager at Google, disagrees with Antonio Villas-Boas’ views. Ho thinks that the idea that overcharging or charging too often is bad is outdated because today’s devices have integrated modern batteries and technologies that optimize the charging process. Only when the phone battery is below 100% will it receive power from the charger, and once it reaches 100%, the phone’s internal battery charger will automatically stop charging.

30%-50% is the ideal battery level of the phone

But there’s one thing that both Schulte and the phone companies recommend to users, to keep the battery at a certain level when not using the phone for a period of time. That level is in the range of 30%-50%, when the battery is at this level, its atrophy rate is slowest.

On the Samsung phone company’s website, it is clearly stated that before not using the phone, users should charge the battery “at least 50%”. Apple also advises users that when storing the device for a long time, keep the iPhone battery capacity at half because this can help increase battery life.

But because users always carry the phone with them and can only charge it for a certain period of the day, it is not easy to keep the battery at 30%-50%.

However, Antonio Villas-Boas must also admit that it is not easy to realize the harmful effects of overnight charging on the aging process of phone batteries. Many users usually change their phones once or twice a year, and these are certainly the ones who will never notice a difference.

Every phone will lose its battery over time, but with the user’s negative charging habits, this process will be accelerated.

Whether the opinion of plugging in the phone charger overnight or continuing to charge it for many hours after the device reaches 100% battery level will cause the aging process of the smartphone’s lithium-ion battery to be accelerated, right or wrong, perhaps users also no need to worry too much. By now, manufacturers have provided the option of replacing the battery at a cheap price. If buying a new machine is beyond your budget, this is also a great option.
