Does Fast Charging Harm the Phone Battery?

    Fast charging technology provides us great convenience in terms of time when we want to charge our phones. So, is using this technology healthy for our phone’s battery? In our article, we explained how fast charging technology works and whether it harms the battery.

    Technology is developing very fast even though we don’t realize it. One of the biggest examples of this is the smartphones in our pockets. Smartphones, each of which are powerful computers, have developed faster than we could have imagined until 15 years ago. We do everything with our phones, from the TV shows we watch to the control of our money. We are so attached to these devices, which are our hands and feet, that we started to think about the charging of these devices rather than our own energy.

    Aware of this, smartphone manufacturers continue to develop smartphone batteries with many other features. When we look at the technologies developed in smartphones, we can say that the most difficult technology to develop is batteries. Unlike hardware units such as processors and RAM, smartphone batteries, which have a much clearer limit, make up for these shortcomings by saving energy from software and hardware. However, despite this, smartphones with a charge that you can use for 1 week still cannot be produced.

    Does Fast Charging Harm the Phone Battery?

    Considering that the technology in smartphone batteries will not change for a while, we can say that the most powerful thing we have is fast charging technology. Phones with fast charging technology can fill a considerable amount of their batteries in minutes. So, does charging your device so fast have any harm to battery life? Today, we will clarify this question that has been on the minds of many.

    Will fast-charging damage the battery?

    Does Fast Charging Harm the Phone Battery?

    Nowadays, we often see fast charging technology, whether it’s an entry-level or a flagship device. You may have seen that phones with this technology get a little hotter than normal when using fast charging. So does fast charging really harm our phone? Let’s put your mind at ease about this. A smartphone battery with all circuits working smoothly will not be damaged during fast charging.

    Our smartphones, as the name suggests, are truly smart devices and have protections to prevent damage to the battery while charging. For this reason, if there is no problem with the electrical components of your smartphone or charger, it is unlikely that fast charging will damage your phone. In fact, we can understand this situation much more clearly by looking at how fast charging technology works.

    How does fast charging technology work?

    Does Fast Charging Harm the Phone Battery?

    If your phone was running from 0 to 100 with the thought of “send as much power to the battery as there is”, your battery would be under high stress and there would be serious consequences. Among these results, there could even be the possibility of the battery exploding, but of course, the engineers took precautions when developing this technology. Batteries that support fast charging technology work in two stages. In the first stage, it is the amount of electricity sent to a battery that is completely or almost empty.

    They send high voltage electricity, especially to batteries below 70 percent. This ensures that 50 percent or more of the charge is recharged in just 10 to 30 minutes. At this point, since the battery is empty, it ensures that the batteries remain healthy in the long run, and it also makes fast charging possible. In some phones, adding two different batteries and sending the current to two different batteries is also frequently used in fast charging technology. For example, Samsung announced that with a 45-watt charger, the Galaxy Note 10 Plus’s battery can be increased from 0 to 70 percent in half an hour.

    The second stage covers the remaining 20 percent or 30 percent of the battery. After your phone’s battery charges extremely fast, up to 70 – 80 percent range, it charges the rest more slowly. Because while the empty battery fills up quickly without experiencing a high voltage, it will have difficulty absorbing all the energy that comes to it, since there is already energy in it.

    Let’s explain fast charging technology with an example.

    Does Fast Charging Harm the Phone Battery?

    We can think of it like pouring water into a bottle. When we want to put water in a 5 liter bottle, we turn on the tap as much as we can. In this process, the water quickly fills the bottle. When we approach the end, we turn the tap down a little so that it does not splash and overflow. If we continue to fill it quickly, it may overflow. The situation with the batteries is similar to our example. If our phones use fast charging until the last moment, by throwing pressurized water into an already full glass, the water will overflow; that may cause a short circuit. This would damage the battery and phone.

    In other words, the fast charging technology in our smartphones, if the phone’s battery is low, first transfers the supported wattage in its system to the device, and then cuts it down so that our phone is not damaged. For this reason, the possibility of fast charging technology to damage the battery and the phone is eliminated.

    When we look at the result, fast charging technology does not harm smartphones. Instead of turning off fast charging, we should use different methods to protect the battery of our phones, which control where to fast charge and where to charge normally with the circuits on it. For this, you can pay particular attention to charging the lithium-ion batteries before they are completely discharged. Keeping it between 20 percent and 80 percent is considered the healthiest range for the battery.

    Today we explained to you whether fast charging technology harms smartphones. So, what are the problems you are having with your smartphone battery? Let’s meet in the comments section.
