Although most of today’s smartphones ship with all-day batteries, consumers still love the flexibility of being able to recharge in the blink of an eye. On Wednesday, Oppo unveiled its latest innovations in the world of fast charging.

The company has long been the leader for fast-charging solutions. Its latest technology is no different. Oppo announced a new 125W system that can supposedly charge a 4,000mAh battery to full capacity in just 20 minutes. If those statistics hold up in the real world, the new solution would beat Oppo’s own record for fast-charging a battery of that size by about 10 minutes.

Getting Faster

Oppo’s announcement certainly deserves some recognition. The ability to charge a phone to full capacity in 20 minutes will be an in-demand feature on flagship devices in the years to come.

So, how exactly did Oppo achieve this feat?

The advancement isn’t solely due to a bigger power adapter. Instead, the system requires that the charger, cable, and smartphone battery are designed together. Doing so increases its overall efficiency and safety. Aside from reaching a full charge in 20 minutes, Oppo claims that its new system can charge a device to 41 percent in just five minutes.

Oppo notes that the phone used for the demonstration (which isn’t a commercial product) uses double-6C cells that feature a “breakthrough battery ratio.”

Meanwhile, the charging adapter has improved power density properties which keep it from getting too big. The cable itself forgoes the typical USB-A connector in favor of USB-C connectors at both ends.

Currently, Oppo hasn’t announced any commercial phones that will ship with the new technology. That shouldn’t be too surprising, though. The company is known for announcing new features well ahead of the products that feature them.

Oppo’s Reno Ace holds the record right now for being the fastest-charging phone in the world. Its 4,000mAh battery can charge to full capacity in 31 minutes with a 65W charger.

Improved Wireless Charging

While Oppo’s breakthroughs in cable-based charging are arguably more exciting, the company also announced some improvements to wireless charging.

Its new 65W AirVOOC tech can wirelessly charge a 4,000mAh battery in just 30 minutes. That’s a significant step forward. Oppo claims that this solution is faster than any currently available wired solution—let alone a wireless one.

Like its 125W wired system, Oppo hasn’t given word on which devices will support the new wireless charging capability or when they will arrive. Regardless, it is refreshing to see the firm adopting wireless charging after refusing to do so for many years.

It will likely take some time for these two innovations to arrive in commercial devices. When they do, it will be a welcome addition.

Once phones can recharge in 20 minutes, worries over a dead battery will essentially become non-existent. Not that they are too concerning in the first place these days.
