What is the correct order for charging your mobile phone and taking care of its battery?

  • The recommended sequence is to first connect the adapter to the power supply and then the cable to the smartphone.
  • Follow the reverse process when disconnecting: first remove the cable from the device and then the charger from the socket.
  • Avoiding voltage spikes and micro-sparks helps prevent pin corrosion and premature battery wear.
  • Temperature control and the use of original accessories are essential to prolong the equipment's lifespan.

Mobile phone charge

Charging our phone batteries is something we do so many times a day that it's become automatic, almost like breathing. However, although it may seem trivial, the sequence of steps we follow when plugging in our devices can make a significant difference to the long-term health of our electronic components.

Many people wonder if it really matters what we plug in first, given how advanced modern technology is and how protective systems it includes. But even though modern phones are more resistant to sudden movements, adopting good charging habits allows us to charge our phones correctly, extending their lifespan and preventing premature wear and tear on the charging port or cable.

The ideal sequence to connect your smartphone

For those who want to take their device care to the next level, the golden rule is simple: power first, then phone . The exact procedure is to first plug the adapter into the wall outlet, connect the cable to the charger, and finally, insert the cable into the phone.

This method is recommended because it allows the power adapter a brief moment to stabilize the energy flow before it reaches the device. If you connect the phone first and then the charger to the mains, the smartphone may be exposed to small electrical fluctuations or initial voltage spikes which, although minimal, accumulate over hundreds of charging cycles.

There's a physical phenomenon involving oxygen and voltage that can generate a micro-spark upon connection. If the cable is already in the phone, this spark can cause oxidation and corrosion of the connectors . A clear example is the infamous black pins that appear on some Lightning cables, which can cause the phone to only charge in one orientation or to stop recognizing the cable altogether.

Furthermore, plugging the adapter into a power outlet without the phone connected is an extra safety measure. In the unlikely event of a serious power failure or a sudden voltage spike in the charger, the impact will not directly affect the phone's circuitry since it will not be connected at that moment.

The art of properly disconnecting your mobile phone

Just as important as the beginning is how we finish the process. To avoid problems, ideally, we should first disconnect the cable from the phone and, once the power flow to the device is interrupted, unplug the charger from the wall outlet.

If we do the opposite and disconnect the power source from the wall while the cable is still plugged into the phone, a reverse current can be generated . This effect can lead to accelerated aging of the battery's chemistry and a reduction in its overall charge retention capacity.

By removing the cable from the smartphone first, we ensure a clean and direct interruption of the charging process . This prevents any residual energy remaining in the adapter from causing sudden discharges or damage to the sensitive electronic components of the charging port.

Other vital tips to prolong your battery life

It's not all about the order of the cables; other factors play a crucial role. Excessive heat is undoubtedly the worst enemy of lithium batteries. It's essential to avoid charging your phone in very hot places or using overly thick cases that prevent the device from dissipating heat during charging.

To maintain the health of the team, it is also recommended to follow these guidelines:

  • Prevent the battery from reaching the 0% charge constantly.
  • Do not leave the charger connected to the wall once the mobile phone has reached the 100% energy.
  • Always use certified and original chargersavoiding low-quality generics that do not regulate blood pressure well.
  • Activate the functions of optimized load that come integrated into the system settings.
  • Restrict applications that consume too many resources and disable connections that we are not using.

It is also advisable not to use the device while it is charging, especially for heavy tasks such as gaming or video editing, as this generates additional thermal stress that degrades the battery cells much faster.

Maintaining a conscious routine that prioritizes plugging in the power first, unplugging the phone first, and monitoring the device's temperature is the best strategy to ensure that our smartphone performs at its best for many years, protecting both the physical integrity of the cables and the chemical efficiency of the battery.
