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.
