What should be connected first, the charger or the cell phone?

THE cell phone charging It is already part of the daily routine and is often also the focus of concern, because you have to be aware of it to avoid disconnecting.

In this context, a dilemma arises that at first glance may seem trivial: What should be connected first, the charger or the cell phone?

Seemingly simple, the question generates debates in online forums and conversations between friends, with divided opinions on what the best practice is, since so far there is no single answer.

Knowing the scientific and technical perspectives hidden behind this issue will certainly help to unravel the “mystery” surrounding the connection sequence in the charging process.

What should be connected first, the charger or the cell phone?

To understand the scope of the dilemma, it is first important to know how the system works. Loading process. Devices, such as smartphones, use rechargeable batteries that store the energy needed to perform all their functions. Charging is done using a battery charger that supplies electricity indirectly.

Some advocate the idea of ​​first connecting the charger to the power source (the plug) before doing the same with the device. They support it this way the initial stress on the battery is reduced preventing the flow of energy from being suddenly transmitted. They add that this practice prolongs the life of the battery and also helps maintain optimal performance over time.

One of the leading manufacturers, Huaweiassures: “If you connect the data cable to the phone first, a large pulse is generated when the power is connected and Excessive voltage can damage the device. “If you plug it into the wall outlet first and then plug in the phone, even if the excess voltage cannot be removed, direct contact between the excess voltage and the phone can be avoided.”

On the other hand there are those who deny them and ensure that modern devices are designed to efficiently manage incoming energy. In other words, there would be no risk of “stress”.

Supporters of device linking say this first and foremost current batteries They are equipped with energy management systems that minimize any negative impact. They note that connecting it earlier can allow for more precise control of the load, thus avoiding current spikes, which improves the efficiency of the process.

Another market giant, SAMSUNGindicates that you leave the charger connected once charging is complete It does not affect your device. But I recommend following them suggestions: Do not leave the device on a blanket, pillow or sofa; always use original battery chargers; Avoid using exposed cables or incorrectly connected plugs and adapters.

Although still no conclusive resultssome studies suggest that the order of connection doesn’t matter, while others indicate that connecting the charger first could have long-term benefits.

However, most experts agree that the differences are minimal and that ultimately other factors, such as quality of the charger and ambient temperature They play a more significant role in battery health.

Beyond the debate on the connection order, the quality of the charger used undoubtedly influences the charging process and the longevity of the battery. Battery charger low quality or not certified They can generate voltage fluctuations that damage the battery over time. In this sense, choosing a reliable charger can be as or more crucial than the connection sequence.

Finally, another factor to consider is the room temperature while charging. Low or high temperatures can adversely affect the battery, regardless of the connection sequence. Avoiding charging your device in extreme environments and keeping it at moderate temperatures is essential to maintaining battery health and maximizing its life.
