There aren’t many cases where the actual specs are better than the rumors, but that’s the case. OnePlus 9 Pro supports 50W wireless charging. That’s a bit faster than the 45W rumors reported earlier this year. We were able to test this feature ahead of its official debut on March 23rd, and the 9 Pro offers really fast wireless charging.
OnePlus claimed that the phone will charge wirelessly (using the new Warp Charge 50 charger) from 1% to 100% in 43 minutes, and it has confirmed this through self-test. This is a huge improvement over the OnePlus 8 Pro’s 30W wireless charging, which charged 50% in 30 minutes. The improvements are not limited to wireless charging or the 9 Pro. The 9 and 9 Pro feature 65W wired charging, which will fully charge in 29 minutes from a drained battery. The base model OnePlus 9 doesn’t get fast wireless speeds, but it can be used with a new charger up to 15W. Additionally, both the 9 and 9 Pro support standard Qi wireless charging at 15W.
Fast charging has been the “thing” of OnePlus for the time being, and, according to COO and head of R&D, Kinder Liu, it has become a huge hit with customers. “Since we introduced the first fast charging technology with OnePlus 3, we’ve heard a lot of positive feedback saying that many OnePlus users have radically changed the way their devices charge. Instead of charging overnight, you just need to charge it for a day while preparing it in the morning. ”
The OnePlus 9 series uses a twin-cell battery design first introduced in the 8T, which is part of the 9 Pro formula to achieve fast wireless charging speeds. Each cell is simultaneously charged to 25W. The OnePlus prevents the phone from splashing by using higher voltage power that generates less heat than using higher amperes and delivering power through a proprietary charge pump.
The 9 Pro’s twin-cell battery design helps mitigate the heat generated by wireless charging, along with other design tweaks to help dissipate heat, such as a thicker copper foil and a larger heat sink. It also has a fan, a key feature of the charger itself, which I’ve been grateful for in my tests. The added fan noise isn’t ideal if the charger is on a bedside table, but quieter charging is supported during sleep mode for Pro 9 owners who want to maintain a night charging routine.
The newly designed charger contains two charging coils, allowing you to charge your phone in a horizontal or vertical orientation. It’s also useful if you want to multitask charging times and watch videos. OnePlus shouldn’t affect the charging speed. We couldn’t confirm it in our initial tests, but we will follow up. There’s still no price set for charger pricing, but last year’s Warp Charge 30 charger wasn’t cheap. The pad version costs $69.95 and the stand version costs $79.95.
