Fast Charging Innovations For Smartphone & Laptops Leave a comment


A part of tech that has improved considerably over recent years has been the charging technology that we use to charge our everyday portable devices. Plugging in your smartphone before going to bed is no longer the only time most people charge their phones. Instead, most people are finding that they have to charge their phones throughout the day, and this is mainly because we use our portable devices more now than in the past.

More Power & Larger Batteries

Smartphones have become a lot more powerful than they were ten years ago with them using newer processors, and most of them can have up to 12GB of RAM. That’s more than most computers and laptops have. With more power being used, larger batteries have progressively been used with phones, with 3,000mAh batteries being the standard for a few years, and now that size is considered to be small.

Now we have phones using 4,000mAh batteries such as the Samsung Galaxy S20, the S20+ has a larger 4,500mAh battery and now we have the S20+ using a 5,000mAh battery. 5,000mAh battery capacities might seem absurd but it’s all in the name of being able to keep up with the power consumption that phones have these days. With that said, charging larger batteries does require some intervention, and that’s why fast charging is present with nearly any phone that you buy now.

However, how do you know what fast charging tech you should use for your smartphone or even your laptop? Most brands such as Samsung and Apple, two of the biggest players in the tech scene are quite vague with their fast charging tech, as they mostly just explain that their phones have “Fast Charging”. So let’s break it down.

From Proprietary to Universal Charging

The most common charging tech that is compatible to use for Android phones is Quick Charge, at the same time Quick Charge is also quite old. Many Samsung phones are now Quick Charge compatible, but at the same time, many of them can also fast charge using Power Delivery.

Most Android smartphones are now going with the Power Delivery compatibility route simply because it’s the more universal type of charging tech that can be used for fast charging phones and laptops, too.

It’s not only Android phones with USB-C ports that can fast charge with PD, but it’s also Apple’s iPhones. Ever since the release of the iPhone X and iPhone 8, the iPhone has been compatible with fast charging with the help of USB-C Power Delivery. However, back then Apple still released the iPhone with a 5W charger only, and even the year after that with the release of the iPhone XS and iPhone XS Max.

It was only in back in 2019 with the release of the iPhone 11 Pro and the iPhone 11 Pro Max that Apple finally decided to include an 18W Power Delivery fast charger with their iPhones. Even now, the current base iPhone 11 still comes with a 5W charger only.

Alright, enough about bashing Apple, on the bright side, they did make it compatible to use with PD even though the iPhone is still using a Lightning port, and so you have to use a Lightning to USB-C charging cable to fast charge it. As for fast charging USB-C Android smartphones with a PD port, you’re going to have to use the more common USB-C to USB-C charging cable.

When it does come to fast charging your phone with a Power Delivery charger, at a minimum, most phones can fast charge with an 18W PD charger. At the same time, newer Samsung Galaxy phones like the Galaxy S20 can support 45W Power Delivery charging, but the PD charger that you use must support USB Power Delivery 3.0 and Programmable Power Supply (PPS), so you can’t just use any random 45W PD charger.

Hints of Wireless only Charging

While we’re on the topic of talking about fast charging for smartphones, there is also wireless charging that has taken a rise in recent years. At its base, most phones with Qi wireless charging compatibility can charge at 5W. However, that is now considered slow wireless charging, as Samsung phones can use fast charge at 10W with wireless charging, and iPhones can charge at 7.5W. That said, you have to use specific wireless chargers that can output that much power.

Going even further is the OnePlus 8 Pro, the latest from the OnePlus brand that finally features wireless charging, and it even has 30W fast wireless charging. 30W wireless charging is insanely fast and faster than most wired charging for phones. At this point as tech keeps getting better, we truly may be looking at phones becoming port-less as wireless charging will be so fast.

Once again, though, 30W wireless charging for the OnePlus 8 Pro can only be done by their proprietary wireless charger.

Power Delivery for Laptops

Alright, so moving onto fast charging for laptops, Power Delivery is still prevalent and rising with its use of charging for laptops. This is because PD charging can output 100W, and that is some fast charging that is perfect for larger and more powerful devices. This is exactly why so many laptops are now using USB-C ports for either connectivity and charging; not just for laptops only, but also because of the cross-compatibility with smartphones.

Since so many phones can charge using a USB-C PD port, you can use that same smartphone charger to also charge your laptop. That said, it’s better to look at it like being able to use your 60W PD laptop charger being used to charge your smartphone. This is because even though an 18W PD charger can fast charge a smartphone, it will most likely slowly charge a USB-C PD compatible laptop.

Yes, a 60W PD charger is perfectly safe to use for charging a smartphone, as the charging speed will adjust to the smartphone. As for getting an idea of just how widespread Power Delivery is, it’s now been used for Apple’s MacBook for a couple of years, many Chromebooks are using it and there are plenty of laptops from brands like Microsoft, Asus, Acer and Samsung that have their USB-C ports being able to be charged from. Eventually, we may be looking at appliances possibly being powered from a USB-C Power Delivery port, far fetched, but it would be neat.
