Smartphones have now become quite sophisticated with their powerful processors, high-quality cameras, immense connectivity, and robust displays — all impressive hardware. Also, the software ecosystem has grown in similar proportions: There are now diverse types of apps on Android and iOS that help us carry out different activities with our phones — staying connected, surfing the Internet, playing games, making purchases, etc. — with remarkable efficiency. And we never get tired of all the good stuff. Naturally so.
To enjoy all these goodies that smartphones have to offer in the digital age, there is no doubt that charging your devices as quickly as possible is essential. The new 30W Warp Charge is OnePlus’ response to this need.
What Is 30W Warp Charge?
Back in 2016, OnePlus featured Dash Charge in the OnePlus 3 and 3T smartphones, and the 22.5-watt charging standard enables phones, such as OnePlus 6T, to go from flat to 60% charge within just 35 mins. Building on this feat, last year December, the Chinese company introduced a new fast-charging standard, dubbed Warp Charge, with the OnePlus 6T McLaren Edition, which produces even faster-charging speeds. This standard promises charging speeds that can go from 0% to 50% within just 20 mins. as well as a full charge in less than 1 hour.
The newly released OnePlus 7 Pro, launched earlier this month, has also joined the fray offering Warp Charge 30 (5V/6A). Later in this post, we will take a look at the OnePlus smartphones currently featuring this new standard.
Though other fast charging solutions are also available on the market allowing you to top up your battery instantly, the edge OnePlus’ tech has over them is that it does not overheat your device. That advantage can be attributed to the fact that the bulk of the charging circuitry gets offloaded onto the wall unit. Warp Charge, like Dash Charge, is based on the Super VOOC charging standard of rival OPPO and comes with a range of features that make it different from most of the other currently available fast charging options.
How 30W Warp Charge Fares in Comparison with Rivals
The 30W quick charging is the fastest speed that OnePlus has been able to achieve as of yet in charging its smartphones.
A standard smartphone battery has highly reactive properties; for this reason, device makers have a lot of safeguards designed into the charging circuitry. Lithium-Ion batteries have the ability to take in more power initially, which tapers out as their charge builds. Fast-charging solutions work on this principle.
The Quick Charge technology of US-based Qualcomm produces a higher voltage in batteries to cut down on charging time. Quick Charge 4.0 has full compliance with the USB-C Power Delivery (PD) spec, is 20 percent faster, and has as much as 30 percent more efficiency than Quick Charge 3.0. Qualcomm has devised a power management algorithm, known as Intelligent Negotiation for Optimum Voltage (INOV), in a bid to achieve better temperature regulation, coupled with safeguards for protecting against overheating as well as overcharging.
With its parallel charging tech, the chipmaker boasts, you can use your smartphone for up to 5 hours with a mere 5-minute charge. Qualcomm licenses the technology to 3rd-party handset manufacturers, which is how phone brands such as Samsung is able to feature Adaptive Fast Charging on their products like the Galaxy Note 9. In the case of Samsung, it is still making use of Quick Charge 2.0, and while there are only a few mobile phones with Quick Charge 4.0 sold on the market, the bulk of today’s flagships feature a charging standard that is based on Quick Charge 3.0.
Meanwhile, OPPO has come up with its own fast charging tech, dubbed Super Voltage Open Loop Multi-step Constant-Current Charging, VOOC. The fast-charging solution is offered in a bi-cell 50W configuration on its products, such as R17 Pro, along with other OPPO flagship devices. The tech is also available on the OnePlus 6T McLaren Edition in a 30W variant. OPPO adopts dedicated circuitry in the charger itself to take care of heat management and dissipation; for this reason, users can only enjoy Warp Charge speeds with OnePlus-branded wall as well as car chargers, like the one you will find in the OnePlus 6T’s box.
What is the major difference between both fast-charging systems? While Qualcomm makes use of higher voltages to charge batteries, its VOOC counterpart opts for delivering higher amperage. For example, Quick Charge 3.0 goes up to 6.5 volts at 3 amperes, generating 19.5 watts, while Warp Charge creates 5 volts at 6 amperes to attain 30 watts. And that much power comes with a handful of advantages.
OnePlus’ 30W Warp Charge Edges out Its Rivals
One of the primary benefits of this option is that it can keep temperatures low as you charge your phone. The fast-charging solution lets you play games or watch videos while charging, without any net drop in charging speeds. But the converse is the case with Quick Charge, where higher voltages invariably result in the phone reverting to normal speeds so as to prevent overheating.
As a matter of fact, OnePlus actively touts the efficacy of its Warp Charge during gaming and claims the new standard will generate as much as a 52 percent charge within 30 minutes. The 30W Warp Charge, with your screen off, can charge your battery from 0 percent to 50 percent in 20 minutes, and as much as 70 percent in 30 minutes. Comparatively, the Note 9 can only go as much as 41 percent after a 30-minute charge from your bundled wall charger.
Further, even though the OnePlus 6T is able to charge as much as 50 percent within just 20 minutes, it needs an extra 40 minutes to charge the battery, fully. That is necessary to prevent any damage to the battery (and more importantly, to the user), with the wall charger offering a limited output of 2 amperes on getting to 75 percent charge and dipping even lower on hitting 85 percent. The microcontroller unit, which lies inside the smartphone, monitors the charge level constantly so as to determine the desired amperage level to be delivered. In the OnePlus 7 Pro’s Warp Charge option, we will keep tabs on its performance to see if the same thing plays out.
The primary downside of the Warp Charge solution is, you have to make use of OnePlus-branded chargers to enjoy the higher speeds on the 6T since OPPO hasn’t yet licensed the tech to 3rd-party vendors.
Can Warp Charge Work on Older OnePlus Smartphones?
As of yet, 30W Warp Charge is only offered on the OnePlus 6T McLaren Edition and the new 7 Pro. Owing to the fact that the latest standard comes with higher charging speeds compared with Dash Charge, it features added safeguards on the smartphone itself. The protection board of the battery is larger with 8 layers for improved distribution of heat, and the wire that is connecting the battery to the board is also wider. Thus, you cannot make use of the Warp Charge system on older OnePlus smartphones.
Late last year, the maker promised to release more phones featuring Warp Charge in 2019. And it is fulfilling the pledge with the release of the OnePlus 7 Pro featuring the new standard. Since we are still in Q2 2019, more devices will still be launched by the Chinese brand, offering the advanced fast charging option.
