Realme’s fast charge tech only needs 5 minutes to reach 50%

Realme has teased the forthcoming arrival of its fastest smartphone battery charging technology yet. It’s called 150W UltraDart Charge, and it will deliver 50% battery charge in just five minutes. To make sure the technology is safe Realme has also announced its UltraDart Charging Architecture (UDCA), designed to balance speed and battery longevity with safety and heat management.

UltraDart Charge will launch on an as-yet-unannounced phone called the GT Neo 3, but Realme has not given a release window for the device and seeing as the Realme GT Neo 2 came along in September 2021, it may not be all that soon. It’s good to see Realme confirm UltraDart Charge will come to a mid-range phone, rather than a more expensive flagship, first though.

Delivering a 50% charge in five minutes will put a strain on the phone’s battery, especially long term, and that’s where the UDCA comes in. Under it, Realme says it will use lithium batteries that will still have 80% capacity available even after more than 1,000 full charge cycles. It will also ensure temperatures do not exceed 43 degrees centigrade so the phone remains usable and comfortable to hold.

What Realme hasn’t said is how long the battery will take to fully charge. Currently, Realme’s 65W SuperDart Charge system recharges a 4,500mAh battery from flat to full in about 35 minutes. Just because 50% charge comes up in five minutes, it doesn’t mean 100% will come in 10 minutes, as the more full the cell is the slower it will charge.

Realme may be making a big deal about 150W UltraDart Charge at Mobile World Congress, but it’s not the first to announce such fast charging. Qualcomm’s 100W Quick Charge 5 delivers 50% charge in five minutes and is part of Xiaomi’s 120W HyperCharge fast-charging system, which can fully charge a phone in 15 minutes. You can experience this for yourself already, as it’s a feature on several phones including the Xiaomi 11T Pro. The company has also demonstrated a 200W HyperCharge system that promises to fully charge a battery in eight minutes.

Superfast charging also runs in the family. Realme is part of the BBK Electronics empire with Oppo, OnePlus, and Vivo. Oppo has already talked about its 125W Flash Charge technology, which will provide 41% charge in five minutes, and OnePlus is also rumored to introduce a similarly powerful charging technology soon.

Realme’s new ultra-premium flagship will come with 125W fast charging in 2022
Realme GT camera module

Oppo showcased its 125-watt flash charge technology in July 2020, revealing that a phone with 4,000mAh of battery could be charged fully within 20 minutes. When you don't have time to top up to 100%, 125W fast charging tech could also allow you to plug in your phone for 5 minutes and charge it to 41%. While it hasn't seen daylight from Oppo, we might get the tech on a Realme phone soon.

The latest development comes from GSMArena, which interviewed Madhav Sheth, VP of Realme and CEO of Realme India, Europe, and Latin America. In the interview with the publication, Sheth revealed that Realme will commercialize 125W UltraDart charging next year. It didn't reveal other details about the upcoming phone, but we can assume it will be a flagship device with top-tier innards.

Phones’ fast-charging tech is confusing, annoying, and will only get worse
Lots and lots of chargers with an iPhone nearby.

Without turning to Google, answer me a couple of questions: What wattage activates fast charging on your current phone, and does the charger you use most meet that requirement? I’m willing to bet few people know the answer to both these questions, and full disclosure here, I’m not one of them.

Don’t worry if you’re with me, phone charging has become so bafflingly complex over the past couple of years that you have to have a degree in electrical engineering to understand it all. The worst part is there’s no end in sight, as phone makers stop putting chargers in the box at all, and fast charging becomes an evermore exasperating minefield filled with proprietary tech, all locking you into buying the same brand forever.
What watt?
Here’s a scenario to illustrate the problem. You’ve bought a lovely new iPhone 12 Pro, which doesn’t come with a charger in the box. Under normal circumstances, this isn’t a massive problem, but one of the features that sold you on the phone is its fast charging, which Apple says boosts the battery from zero to 50% in about 30 minutes. Your new phone replaces an iPhone X, so you first decide to continue using the charger that came with it.

Realme 7 Pro hands-on: A super-fast-charging bargain
realme 7 pro hands on features price photos release date back hand

Realme is a relative newcomer to smartphones, having only launched in Europe in mid-2019 following its debut in China the year before. But it has since built up a portfolio of well-priced phones. The latest is the Realme 7 and Realme 7 Pro, which now come to the U.K. and Europe after debuting in India this September.

I've been using the Realme 7 Pro for a few days, and it has a feature we don't see very often on phones at low prices: Very fast charging. Not charging that takes 90, or even 60, minutes -- I'm talking about charging that Realme says takes just 36 minutes. That's a big selling point, but can the 7 Pro overcome the software problems that have affected some of its previous devices, to make it really desirable?
We'll talk about the battery shortly. Let's see the phone in more detail first. Rejoice, lovers of flat-screened phones, for the Realme 7 Pro’s 6.4-inch screen does not have a curve running down either side. Some will argue this makes it better for gaming and less likely to have edge recognition problems, while others will lament the less-modern design and how uncomfortable this can make gesture controls. It's mostly personal preference.
