Expert told how to increase battery life by 5 years by removing the cover:

News India Live, Digital Desk: In the world of smartphones these days Fast Charging Is considered a big feature. Now speeds like 30W, 65W, 100W or 120W have become very common, and we find it very convenient that the phone gets fully charged in 15 minutes. But one fear always remains—is such a fast charging speed reducing the battery life of our phones from within?

Often experts and people with technical knowledge say that charging at higher watts (W) is harmful for the battery in the long run. After all, how much truth is there in this, and if it is true then why should we buy expensive fast charging phones?

Let’s understand how the technology behind fast charging works, how it affects the battery, and what “cooling secret” you can use to save it.

Actually, every smartphone battery is lithium-ion or lithium-polymer. The lifespan of these batteries depends on the charging cycle, not the charging speed. Typically, these batteries lose about 80% of their original capacity after 400 to 500 charging cycles.

The main danger in fast charging is not the speed, but the effects caused by the speed. Heat Is of.

The danger is from ‘heat’, not from speed!

When you supply power to a battery rapidly (say at 100W), the lithium ions move quickly from one place to another. Due to this fast chemical reaction Heat is generated.

Science says: The biggest enemy of lithium-ion batteries is heat. Charging at high temperatures puts stress on the components inside the battery, causing its overall life to rapidly reduce. This is the reason why the phone gets hot when it is put on fast charging.

What solution did the phone companies find?

The good thing is that smartphone companies (like Samsung, Xiaomi, OnePlus, Apple) know this problem, so they design their fast charging very intelligently:

• Then, as they approach 80%, they reduce the charging speed significantly (trickle charging), so that there is less stress on the battery.

1. Dual Cell Design: Many companies, especially high-wattage companies, split the battery into two parts (e.g. 2x 2500 mAh instead of 5000 mAh). Due to this, the charging load is distributed between both the cells and less heat is generated.

The Cooling Secret That Will Save Battery

If you have a phone with fast charging and you want to keep its battery life long, then it is most important that you keep the phone cool.

The biggest cooling secret is to remove the cover or keep the phone open while charging.

Your phone is already heating up while charging. If there is a thick, non-breathable cover on it, then the heat of the phone is not able to come out and the temperature inside the phone increases a lot.

Here are some other important tips:

1. Avoid charging pads: If you use a wireless charging pad, make sure there is airflow between the pad and the phone. The charging pads themselves also produce heat.
2. Do not use while charging: Do not do high-processing work (like gaming or video editing) while charging. By doing this, both the processor and charging together generate excessive heat, which directly reduces the life of the battery.
3. Charge at a good charging break: Never charge the phone overnight or to 100%. Try to charge between 20% to 80%. This reduces the stress on the battery.

The bottom line is that companies put safety measures into fast charging, but you should also take care on your part to remove the cover and prevent overheating.
