Many times, in case of emergency, the phone has to be charged from another charger. In such a situation, this question comes in the mind of many people whether the phone will get damaged by charging it with a high power charger. If this question bothers you too, then today we have brought the answer. This will let you know whether a low capacity phone will get damaged when charged with a high-powered charger or not.

Charging with high power charger is safe

If your phone is of 18W and you charge it with an 80W or 100W charger then there is no need to worry. It is completely safe and will not cause any harm to your phone and battery. For this, there is a technology in charger and smartphone, which is called Power Negotiation Protocol. This technology ensures that the phone gets power according to its capacity. Therefore, even if you use a charger with more power, the phone will still get charging according to its capacity.

How does this technology work?

The power negotiation protocol tells the charger how much capacity the phone has and how much power it will need to charge. After this the charger delivers only that much power. For example, even a 100W charger will supply only 18W power to an 18W phone. This keeps the phone and battery safe.

Battery management system also helps

Nowadays smartphones also have battery management system. It manages charging voltage, temperature and current using power negotiation protocol. If the phone overheats during charging, it stops charging, thereby protecting the battery.

There was a time when it took several hours to charge a smartphone. One had to wait for 1-2 hours to charge the battery even a little, but now things have changed due to fast charging. Now the phone’s battery gets fully charged within a few minutes. Have you ever wondered how a phone gets fully charged within a few minutes of charging? Today we have brought the answer to this question.

How does standard charging work?

Before understanding fast charging, it is important to understand standard charging. In standard charging, when you plug the phone into the power plug, the electric power (Watts) is converted into current (Amperes) and reaches the battery through the cable. Due to this, a chemical reaction starts in the battery installed in the phone, due to which ions move from the negative terminal to the positive terminal, where energy is stored. These batteries have an electronic control (integrated circuit), which prevents the battery from overcharging.

How is fast charging different from this?

Fast charging also works on the same principle, but in this, more power reaches the battery than standard charging. The standard charging adapter works in the range of 2-4.2 volts and has low current flow. In comparison, the fast charging adapter is capable of 5V-12V and it flows faster current. This charges the battery quickly. It sends maximum current to charge the battery quickly. Fast charging batteries have a higher peak voltage capacity and their integrated circuits are specially designed to prevent damage to the battery.
