Smartphone Battery Tips: It often happens that the phone's battery starts draining at the most inopportune time and there is no charger nearby. In such a situation, people immediately resort to laptop and start charging the phone through USB. Nowadays, most smartphones and laptops come with USB-C port, which makes this method seem even easier. But the question arises whether this method is completely safe or it can harm your phone.
How does the laptop charging system work?
Today many devices support USB-C and USB Power Delivery (USB-PD) technology. This means that the phone and the charger communicate with each other to decide how much power to take. When you connect the phone to the laptop charger, the device itself takes power as per the need. This means that even if your charger is more powerful, the phone will still draw as much energy as it safely requires.
Is it safe to charge phone with laptop charger?
This method is considered absolutely safe under the right circumstances. For this, it is necessary that both your phone and charger support USB-C Power Delivery. Due to this, the correct balance of power is maintained during charging.
Apart from this, one should always use good quality or original cables. A bad or cheap cable can cause unstable charging and risk damaging the device.
Today's smartphones are designed in such a way that they keep themselves safe even from high watt chargers. Therefore, even a 65W or 100W laptop charger does not pose any direct threat to the phone.
Does this affect the speed or performance of the phone?
The job of the charger is only to provide power to the battery, it has no direct relation with the speed or performance of the phone. It does not affect the processor, RAM or performance of apps. However, if the phone gets a little hot during charging, the phone may temporarily reduce its performance to control the heat. This is a normal process and there is nothing to worry about.
What things to keep in mind
If you are charging the phone from a laptop then some precautions are necessary. Always use a reliable cable and ensure that both the charger and the phone support the same standard. Charging your phone with a laptop charger is a safe and easy option these days, especially when you don't have a charger available. If you use the right cable and the right device, it neither harms the battery nor has any effect on the performance of the phone.
