Should you plug your phone in first or the power source first when charging it? It turns out there is such a big difference! [Copy link]

When charging your phone, should you plug it into the power source first or the phone? It turns out there is such a big difference!

I wonder how long your cell phones usually last,

a day? half a day?

or do they die before you can even play with them?

Anyway, I always have to carry a data cable with me,

because my cell phone can die without you noticing. Why are there different situations? Before understanding this, let us first understand another concept: surge. Surge refers to the instantaneous voltage that exceeds the normal working voltage. Also known as instantaneous pulse voltage, it is a short-term current that appears in the circuit and lasts for one millionth of a second. When our electrical appliances come into contact with the power strip, a surge occurs, and the destructive power surge to the equipment is also quite strong! For example, when we turn on several high-power devices at the same time, we may hear some buzzing sounds from the power strip, which are caused by the surge! Therefore, a large number of surge-resistant power strips have appeared on the market. If you use a surge-proof power strip: It doesn't matter whether you plug in the power supply or the phone first when charging your mobile phone.

If you are using an ordinary power strip, it depends on whether your charger is original or non-original.

When using the original charger, it basically has no effect on whether you plug in the power supply or the phone first. However, the result of a non-original charger is different. When the phone is plugged in first, a relatively large voltage pulse will be generated, which may cause harm to the phone.

Therefore, when charging your phone, no matter what power strip or charger you use, plugging in the power source first will not generate a pulse voltage, which is relatively safer.

Otherwise, the phone battery will age faster, the battery life will get worse and worse, and even cause a series of problems with the phone. Following the same logic, when the phone is fully charged, you should also unplug it first, because when unplugging the charger, the charger is prone to generate reverse instantaneous current. If you do not unplug the phone at this time, it may also damage the phone.

Summary: When charging, plug in the power supply first and then the phone; after fully charged, unplug the phone first and then the power supply.

Actually, it is to prevent the spike from damaging the phone. However, the phone also has a protection function.

The article reposted by the original poster was written by a complete layman. This type of article with charts and terms is very common in the pseudoscience community, but even the basic concepts and phenomena are not used correctly or explained clearly, which is really harmful to people. The original poster should read less such garbage in the future and just learn the technology realistically.

I agree with the above view, there are not so many problems
