Today, OnePlus has confirmed ahead of the launch on March 23rd that the OnePlus 9 Pro will support Warp Charge 50 Wireless, which is the company’s first 50W wireless charging technology. It already introduced wireless charging in the OnePlus 8 Pro with Warp Charge 30 which takes 30 minutes to charge the phone’s 4510mAh battery from 0 to 50%. The OnePlus 9 Pro’s 50W wireless charger will take 43 minutes to charge the phone from 1% to 100%. In China, the company has confirmed that the phone will come with the same 4510mAh battery as the previous one.

OnePlus said that it uses a dual-cell configuration that fills up both batteries at 25W each through the charging coil. It also optimized the entire chain of components, such as coils and charging ICs, and used charging pump technology.
Warp Charge 50 Wireless Charging speed can be improved by either increasing amperage or voltage around 20V-2.5A. The high wattage is transferred into the OnePlus 9 Pro through the coils, after which 20V-2.5A power goes through our proprietary isolated charge pump, which turns 20V-2.5A power into 10V-5A power. This power feeds into our new twin-battery system, two battery cells in series together. Each battery gets around 5V-5A, which translates to 25W each, 50W in total.
Warp Charge 50 Wireless, we chose to use high voltage power instead. We also came up with several additional innovative designs to reduce heat even further: -
- The OnePlus 9 Pro's twin battery design adopts our customized new battery cell, which has a lower internal resistance, meaning it will produce less heat during charging.
- We increase the thickness of the coils inside the phone by 10% compared to the 8 Pro, as resorted to a customized cable to help the heat dissipation.
- The OnePlus 9 Pro is designed to have better cooling performance than our previous generation of devices, with a larger vapor chamber, thicker copper foil, and graphite that helps keep the phone cooler while gaming as well as during fast charging.
The new charger continues to offer bedtime mode. You can enable this mode through settings to schedule around your sleeping hours e.g., from 11 PM to 7 AM, giving you a quieter overall charging experience during sleep. Compared with competing products, the wireless charging speed of the OnePlus 9 Pro exceeds the wired fast charging speed of other premium flagship smartphones.
The wireless charger is now equipped with two coils – one on the top and one on the bottom – so that you can choose between charging vertically or horizontally, allowing you to charge wirelessly while watching videos. The new charger also uses a detachable cable design, so now you can plug in the red cable of the Warp Charge 65 charger included in the box or use other USB-PD chargers to achieve up to 50W charging speed.
The Warp Charge 65T that was introduced with the OnePlus 8T is now present in both the OnePlus 9 and 9 Pro smartphones and these phones use the same dual-battery layout present on the OnePlus 8T, with the two internal batteries charging at up to 32.5W, for a combined peak charging of 65W.
While the OnePlus 8T takes 39 minutes to charge from 1% to 100% with Warp Charge 65, the OnePlus 9 and 9 Pro only take 29 minutes to charge from 1% to 100% with Warp Charge 65T, making it one of the fastest wired charging solutions on the market.
