Is it harmful to the battery to charge the mobile phone overnight? The answer is amazing
4hw.com.cn: in the era of smart phones, the power of mobile phones makes everyone more and more nervous. I believe many people have the experience of plugging in their mobile phones and charging them all night before going to bed. Although many science popularization websites will not explode no matter how long they charge their smart phones, because it has a battery protection mechanism and will automatically disconnect when full, some people still say on the Internet, Charging the mobile phone all night will cause great damage to the battery, so let's see what experts say.
For years, it has been said that charging your smartphone at night until the next day will damage the service life of the battery. Although many people do this, some still warn that charging a fully charged battery will affect its capacity.
Perhaps, such concerns would have some truth in smart phone batteries a few years ago, but today, such statements are actually exaggerated.
You don't have to think too much about how to protect your smartphone battery, even if you plug it into the socket all night.
Recently, Kyle & middot, head of ifixit company, which is famous for repairing and dismantling electronic products, from California; Kyle Wiens said: 'charging the phone all night will not reduce the service life of the battery. This is because each lithium battery has its fixed charging cycle, which refers to the complete charging times that the smartphone battery can carry out before obvious degradation. For example, if your mobile phone uses half the power, and then you plug in the socket, you will charge half the power of your mobile phone, which takes half a cycle. "
Wiens continued: 'the average smartphone has about 400 charging cycles, which helps the device to last at least a year and a half. Of course, if the equipment is well maintained, it is not surprising that it will take more than this time. However, even if you plug your mobile phone into the socket for charging overnight, it will not change the frequency of the battery cycle. Only when you use your mobile phone will you consume electricity. "
Anker, a manufacturer of battery and charger accessories, also said: 'in terms of the gradual degradation of battery life, we must understand that mobile phone batteries are indeed aging, but charging mobile phones overnight will not have much obvious impact on this. This is because modern smart phones are designed to avoid absorbing more power, not the more the better. In other words, they know when to relax. "
'as its own name implies, smart phones are smart. Each unit has a built-in chip, which can prevent charging once it reaches 100% capacity. So if you buy your phone from a certified legal retailer, you don't have to worry about the problem of charging your phone. "
Wiens said: 'the idea that charging a mobile phone overnight will damage the battery life usually comes from people's experience of old technology. I think the reason why people feel this way is that during the day, the battery indicators of some mobile phones or laptops will change back and forth between 99% and 100%. This is more important than the errors shown to you by the measurement software. "
However, there is a potential danger of plugging your smartphone into the socket overnight, and that is the temperature. As apple warned on its website, lithium batteries used in modern smartphones can be degraded by extreme heat. So whenever you charge, it's worth noting.
Wiens said that the most common complaint he saw about the battery life of smart phones was that people said that their phones would not be charged after reaching a certain percentage, or there would be a certain probability of direct damage and unavailability.
What these people need to do may be to replace the battery, or they can try to use the power of the device to 0% and then recharge, which will effectively 'recalibrate' the internal counter of the battery. Nintendo recently proposed such a similar method to fix the battery problem on the switch.
Anyway, if your cell phone is low before going to bed, you can plug it into the socket and sleep safely until the next morning.
