The Ultimate Guide: What Is Fast Charging?

You hear a lot about fast charging phones these days, but exactly what does this mean? And more so, how does it work? In this guide, we break down all of your fast charging questions. We will teach fast charging and wireless fast charging, touching on Qi wireless charging, too. We will also discuss the fast charging standard of USB PD and talk about some of the common myths associated with fast charging and debunk your worries about overheating your phone with a fast-charging device. 

Last, but not least, we will break down a series of Case-Mate fast-charging phone accessories, including our FUEL line of USB-C power adapters, power banks and even our fast-charging wireless chargers and Power Discs. 

So, what is fast charging? Let’s get started and teach you everything there is to know.  

So, What Is Fast Charging?

When you charge your phone or tablet with its regular USB port, it only receives 2.5 watts of power. Technically speaking, a fast-charging cable or accessory refers to anything that charges using 2.5 watts or higher. However, this is just not enough for today’s power-consuming phone users and all the time spent playing online games, taking photos and watching videos online. Instead, you need a higher wattage to really get the job done.

At the very least, you should be looking at 10 watts of power. To put things in perspective, an extremely fast charging speed would be at least 25 watts. (Hint: You’ll find this in Case-Mate power adapters.) For fast-charging something more extensive like a laptop, you’re looking at around 45 watts to 60 watts, depending on many variables like the processor and battery size. 

What Is Wireless Fast Charging?

And What Is Wireless Fast Charging?

Since you might find lots of wireless fast-charging accessories and cables, let’s explore this a bit more in detail, too. Wireless charging is a lot like regular fast charging but uses Qi standard to transfer the power over airwaves from the charger to the device. 

When Qi was first used as wireless charging accessories, it wasn’t much to write home about, capping out at roughly 5 watts of power. Fortunately, there have been lots of advancements in what Qi wireless charging has to offer. Today, you can find Qi-enabled wireless chargers that provide up to 65 watts of power. Although, you may find it more commonly around 10 watts, which is perfectly sufficient for charging a smartphone device. 

However, one thing to keep in mind is that — at least for now — Qi wireless charging is slower than simply plugging in your phone directly to a wire or a fast-charging power adapter. Even Apple’s latest proprietary MagSafe wireless charging technology charges at 15 watts. Compared to the iPhone 13’s fast-charge abilities when connected to a 20-watt adapter — a 50 percent charge in 30 minutes — it still doesn’t cut it. So for the fastest charge, a rapid-charging power adapter will do the trick, or at least a standard cable.

USB PD: The Standard in Fast Charging

Fast charging is different for each phone manufacturer. Apple and Google’s fast-charging methods and standards are different from Samsung’s. For instance, Apple and Google use the USB Power Delivery (also known as USB PD), while Samsung uses Samsung Adaptive Charging. Then, you have QualComm QuickCharge, too. At the end of the day, each standard is designed to give your phone the quickest boost possible whenever you need it most.

Each fast-charging system offers its own benefits and advantages. However, there is one standard fast-charging method that seems to be climbing the popularity ranks and that is the USB PD standard. Why is this exactly? USB PD has been the rapid charge of choice by the biggest names in the phone manufacturer industry, including Apple, Google, Samsung and more. USB PD is even used by some PC brands, as it’s actually fast enough to fast charge a laptop. 

USB PD is also very powerful. It can reach up to 100W, which is more than sufficient to rapid charge a smartphone device, but equally capable of charging an iPad or laptop, too. How fast is the USB PD? It can fully charge a device within an hour. 

Case in point: This is also the standard that Case-Mate uses for our fast-charging phone accessories like our wireless chargers, power adapters and more.  

Is Fast Charging Dangerous for Your Device?

Is Fast Charging Dangerous for Your Device?

This question gets asked a lot. After all, while your device is charging, it may even warm up. So what’s that all about and, more so, it is safe?

The assumption is that this warming and faster charge will strain or weaken the battery over time. But this simply isn’t true. Phone manufacturers and fast chargers are designed in such a way that they essentially boost your phone in two phases. With these two fast-charging phases, a phone can take on the initial boost — roughly 60 percent charge — using all its strength. Then, once it reaches this mid-way point, it reduces the intake to finish the charge. And it’s this second phase that keeps your phone from overheating. 

Using other chargers will also not damage your phone or its battery. Your phone is built for fast charging. You can even find detailed specs on your phone manufacturer’s website or manual. And so long as you use compatible — Qualcomm Quick Charge or USB Power Delivery certified — chargers made from reputable brands, it will work perfectly fine and never damage the battery or anything else.

More Fast-Charging Tips and Tricks

Whether you have a fast-charging device or are considering a type of fast-charging enabled phone, here are some extra tips and tricks that might come in handy.

Is your device not fast charging? Some phones and devices need to be enabled first. Samsungs, in particular, may require this extra step. Simply find the Settings app and choose:

Device → Maintenance → Battery → Advanced Settings 

From there, you can toggle on the fast charging. Be sure to also turn off the screen to begin fast charging.  

Another common reason your device might not be fast charging is that your software isn’t up to date. If you have enabled fast charging, try updating the software and restarting your device. 

How to tell if your device is fast charging. Apple’s iPhones fast charge automatically and are more discreet about it, so there’s not really a real indicator. However, Samsung will show a lightning bolt symbol on the screen. The Google Pixel and other phones may even state the word “fast” or “rapid” charging to let you know. 

Want a fast-charging phone? If your phone doesn’t support fast charging, you might want to consider an upgrade the next time you need to buy a new phone.
