Today, there is a new trend in the smartphone industry since the introduction of Fast Charging Technologies. I often feel like every single day, a new company coming up with a new smartphone and how their charger can charge their Smartphones. But most of the Smartphone brands don’t tell is you is that “faster charging doesn’t come for free”. 

The way a battery works is the two poles i.e. a positive and a negative one. At the negative end, we have a ton of negative electrons and at the positive end, we have less of them.  Actually, Charging means the flow of these electrons from negative to positive to maintain the equilibrium, and on their way of flowing they charge the components attached to the same circuit. Once these electrons are completely flown, the battery is considered dead, and here recharging comes into play. Here electricity is generally used to reverse the previous flow of electrons. Most of the fast chargers push these electrons faster decreasing the elapsed time of charging. 

But the above fast charging technology comes with many backlogs. Some of them are to be discussed below in the article. But before we start, make sure you read the full article and subscribe to us for the best knowledgeable content.

  • Less Capacity

The fast charging in smartphones reduces the capacity as this increased charging speed increases Gap between two cells for the stability of the battery. In every battery, between the two poles, you also need a separator so that electrons don’t flow from one side to another side directly but taking the circuit we actually want it to flow. The faster you want to charge the battery, the thicker you need a separator. In return, this reduces the amount of useable capacity as well as battery density falls subsequently. Nowadays, we often notice phones coming with two separate cells are just due to the same reason. 

  • Overheating

Faster charging means faster electron movements which create tremendous energy in the form of heat which is not a battery’s best friend. This in return changes the shape and ability to hold charge beneath a cell fall gradually. As per a survey, if you are charging your battery consistently at 30° then you can easily expect your battery’s charge holding capacity to fall up to 20% of its previous capacity and 40% fall over 40° continuous charging over a  year. 

The only solution to use your phone while charging and also prevent overheating is Bypass Charging that ensures supplying energy directly to the components but not the battery. 

  • Diminishing Returns

The powerfully you charge your battery, the more you get the Diminishing Returns. You often had previously noticed when any manufacturers promote the fast charging technology they do this by promoting their starting charging figures as of in how many times the battery reaches the first 50%. It clearly means that what it shows is not what is done. Actually clearing the previous line, If your phone shows to be 100% powered then it’s not 100% but something less than that number and it’s termed Charging Buffer. 

It doesn’t matter how fast your device in its starting phase but what matters is you need to slow your charge drastically as it fills in the later phase to ensure the battery’s health. As a result, your 60W charge is not as fast as twice of your 30 Watt Output Charging Technology, and similarly, your 120W charger is not as fast as twice of your 60W charger. 

For this only reason, Smartphone brands are integrating the feature of Slow Charging as an additional feature. Devices like ROG Phone 3 showed similar features and phones running on iOS 14 ensure this feature for better battery life. 

So these were some of the backlogs of Fast Charging technology. We will be back with an amazing article soon with some of the redeeming factors and additional features that Fast Charging power us. Till then stay safe, stay at home. This was Raj from signing off. Thank You.
