Exploring the best phone chargers in our latest blog post. But before you make your choice, it's crucial to understand the various charging protocols at play. Dive into this other blog post to learn more about the various charging protocols. Click here to learn more!

In this blog, we'll delve into the intricacies of fast charging. Navigate quickly:


In the world of fast charging, major phone manufacturers like Samsung and Apple have their unique approaches. Samsung's latest models, like the S23 Ultra and Plus, now support impressive 45W PPS (Programmable Power Supply) fast charging, while Apple appears to be gearing up for a 35W upgrade with the iPhone 15. These developments reflect their evolving stances on USB-C, PPS, and fast charging.

In contrast, some lesser-known brands, like Xiaomi, have embraced rapid charging with an astounding 300W record-setting prototype, the Redmi Note 12 Pro+. These diverse strategies in fast charging set the stage for our exploration into the technology's inner workings, benefits, and practical tips.

Understanding the Technology and Its Complications

Fast charging, underpinned by technologies like Qualcomm Quick Charge, USB Power Delivery (PD), and Programmable Power Supply (PPS), has transformed the way we recharge our devices. It harnesses higher power levels to significantly reduce charging time, a boon for our fast-paced lives. However, as with any innovation, fast charging comes with complexities that affect battery health.

Impacts on Battery Life:

Fast charging primarily impacts battery health in two ways:

  1. Heat Generation: The accelerated charging process generates more heat within the battery. Over time, this heat can expedite chemical reactions inside the battery, potentially leading to capacity degradation.

  2. Charging Cycles: Each charging cycle puts stress on the battery and gradually reduces its capacity. Fast charging, often used more frequently due to its convenience, can lead to more cycles and, consequently, affect long-term battery life.

Mitigating the Risks:

Manufacturers have made significant strides to address potential risks, ensuring that this technology is not only convenient but also safe for both your devices and you.

Optimal Charging Conditions: Modern devices are designed with sophisticated temperature management systems. They can intelligently adjust charging speeds and temperatures to avoid excessive stress on the battery. This means you can confidently charge your device in various environmental conditions without compromising its health.

Balanced Charging Strategies: Manufacturers have implemented advanced charging algorithms that optimize the charging process. Fast charging, while efficient, is no longer a constant necessity. You can choose to charge your device rapidly when you're in a hurry, but these smart algorithms also allow for more relaxed charging sessions. Keeping your battery around 80% capacity, rather than always aiming for a full 100%, can extend its lifespan significantly.

Quality Chargers and Cables: While manufacturer-recommended chargers and cables are typically top choices, third-party options are no longer the risky proposition they once were. Manufacturers have established safety and compatibility standards that quality third-party accessories adhere to. So, understanding your device's requirements and selecting gear accordingly is your ticket to safe and efficient fast charging.

The Latest in Fast Charging:

Fast charging technology is in a state of constant evolution, and leading smartphone manufacturers are at the forefront of these advancements. Let's take a quick look at some of the most popular protocols utilized by major players in the industry:

  • Samsung: Samsung has been steadily increasing its fast charging capabilities. Their latest models, such as the Samsung Galaxy S23 Ultra and Plus, now support an impressive 45W PPS (Programmable Power Supply) fast charging, offering a quicker power boost.

  • Apple: Apple, known for its iPhones, has traditionally been more conservative with fast charging. However, recent rumors indicate that the upcoming iPhone 15 might bring a substantial upgrade, potentially supporting 35W fast charging.

  • Xiaomi: Xiaomi is renowned for pushing the boundaries of charging speed. Their Redmi Note 12 Pro+ prototype created a buzz by demonstrating an astonishing 300W fast charging capability, showcasing their commitment to rapid charging technology.

  • Huawei: Huawei, with its FastCharge Protocol (FCP) and SuperCharge Protocol (SCP), has consistently improved its fast charging capabilities over the years, with the latest generations supporting speeds of up to 40W.

  • Oppo: Oppo has made significant strides in fast charging technology with its VOOC and SuperVOOC protocols. The brand continues to innovate, with SuperVOOC models capable of delivering power at staggering speeds of up to 240W.

So which charger do I choose?

Note: The compatibility information provided here is based on typical charger specifications. Always check the specific requirements of your device for accurate compatibility.

10W Chargers:

These can be used for older devices from before 2016 and smaller wearables such as earbuds and smartwatches. After all, these will not charge any faster on a bigger charger.


20W Chargers (PD3.0 and QC3.0):

These chargers are ideal for iPhones that still cap at 20W fast charging.


25W and 30W Chargers (PD3.0 and QC3.0):

These chargers are suitable for most A-brand smartphones up to 2020, in particular those who are built with a Qualcomm processor will have a seamless charging experience as the chargers support QC3.0.



65W GaN Chargers (PPS):

These chargers are the safest on the market due to their low heat GaN technology, in addition they all support Programmable Power Supply, making them 100% compatible with the latest Samsung phones.
