Does It Really Work?

Power Delivery Charger: Everything You Need To Know About Fast Charging 2

We desire more from technology nowadays, and we want our gadgets to be faster and long-lasting. This desire has emphasized the significance of having our smartphones charged all day. In recent years, along with screen resolution and camera pixels, battery performance has become an essential factor.

One of the reasons why fast chargers have become so common, more specifically for high-end devices, is the continued priority on battery performance. Battery life has become a more crucial factor in deciding whether to buy a smartphone.

Top-quality phones are the fastest and most efficient of them all. If the battery is about to die before the end of the day, the smartest way is to instantly charge it using your lightning-fast charger.

But now power delivery chargers for iPhones and other smartphones on Ugreen’s page are so common and efficient that people raise questions like: Can a power delivery or fast charger short-circuit the battery? Will it decrease the phone’s capacity and power with time? Does a fast charged battery drain quickly?

Power Delivery Charger: Everything You Need To Know About Fast Charging

Here are some important things you need to know about PD and fast charging.

  1. How Fast Charging Works?

Let’s go over some key battery recharging basics before we get into fast-charging requirements. Smartphone batteries, like other electrical gadgets, have a set voltage and can only receive and generate a particular flow of charge or current. But, in order to recharge a battery safely, chargers are made to follow very precise working restrictions, especially in terms of voltage. Fast recharging a battery includes more than simply applying as much voltage and current input as possible. Rather, the recharging of a battery is categorized into two phases: steady current and constant steady voltage.

Now, a fast charger is made on the concept of input as much current as possible in the steady current phase before it reaches its maximum voltage. Using this concept in the steady voltage phase causes the battery to heat up and reduces battery life.

Consider a battery to be a sponge. When you initially wet a dry sponge, it quickly absorbs the water. This is the fast-charging stage for a battery. More pouring equals more absorption. During this phase, fast chargers deliver a large amount of current. As the pouring continues, the sponge’s absorption rate slows, and the sponge’s surface fights to soak into the soaked sponge. Similarly, the battery will charge rapidly from 0 to 60 or 70 percent, but it will take some time after that.

Because in the charging phase after 70% more input can be harmful to the battery, thus smartphone manufacturers make chargers slow down and allow a safe amount of current in the battery. Therefore, buying a good quality PD charger can get your battery charged in a few minutes and is not harmful to long-term battery performance because it works on the concept of flooding more current in a steady current phase. These chargers are mostly more effective when the battery is less than 50% and are not advised if the battery is 70-80% full. Their impact on charge time diminishes after the battery reaches 80%.

  1. Is Fast Charging Safe?

The amount of current to receive from the charger is controlled by the smartphone and not the charger. Today’s technology has made smartphones programmed in a way that they know how much current and voltage is required to function effectively. And so, the user has nothing to worry about overcharging or high power because a smartphone has the ability to control the input and output to keep itself safe.

However, fast chargers can heat your smartphone when charging because more current is inputted in the steady current phase. It has no harmful effect on your device in the long run. Fast charging is safe and does not affect battery performance and timing.

It is advised to use branded fast chargers and cables to ensure device safety. Fast chargers are just as secure as normal chargers when properly approved accessories are used. Always confirm that your fast charging accessories are certified to work with your smartphone to guarantee safety and optimal speeds. The charger or cable must be certified to guarantee that it satisfies performance and safety requirements.

  1. How To Maintain Battery Performance?

A fast charger can recharge your smartphone up to 75% quicker than compared with regular 5W charging. This means you will spend less time hooked up until your phone is recharged.  As has been discussed above, fast charging has no harmful effect on battery life and performance, but still, some people face such issues, and they assume that it is due to fast charging. 

Here are a few important things to keep in mind to maintain and improve battery timing and performance:

  • Discharging a battery to 0 percent might result in chemical processes that reduce the battery’s durability with time.
  • Plug in the charger When your smartphone’s battery level drops to roughly 30%, which is well over the lowest battery levels.
  • Temperatures as high as 35 degrees Celsius can degrade a battery’s performance, and an overheated battery may explode under severe situations.
  • To get the most out of the smartphone’s exclusive fast charging, you should use a charger that’s appropriate for it.
  1. Things To Keep In Mind When Buying A Fast Charger?

Before buying a fast charger, you need to evaluate your needs to buy the perfect charger with the right accessories that can cover all your needs. 

  • Do you have a habit of charging many gadgets at the same time? If that’s the case, a charger with many ports is generally a good idea. 
  • Do you need to charge your AirPods or Smartwatch?
  • Check for different brands and their reviews before going to a shop.

When buying a fast charger, there are a few factors to keep in mind:

  • Check if the USB charger that you are buying supports Power Delivery (PD) or not. Power Delivery is the fast charger that will enable your smartphone or other devices to charge faster.
  • If it is a USB-C connection, an adapter will also be required.
  • Buy from a well-recognized brand because using off-brand cables or adapters results in overheating or short-circuiting your smartphone or may reduce your battery performance over time.

If you just have 10 to 15 minutes to recharge, you may receive up to 30% more battery power using a PD charger. You can recharge your smartphone up to 60% if you have 30 minutes. This new fast charging technology has the potential to revolutionize the world.

Fast charging may have appeared to be a premium option in the past. However, when more smartphones, PCs, and gadgets support it, PD technology will make it easier to utilize your electronic devices. Not only will your battery timing and performance improve, but you will also save money by simply having to use one charger for all of your gadgets. 

Simply said, Power Delivery is a far more convenient and simplified method of charging all of your gadgets. As a result, USB PD is expected to grow in popularity among consumers. With these developments, we may look forward to a time in which fast charging and long battery timing are the norms rather than the exception.
