A new battery charging technology is being unveiled later this week that is expected to transform how long it takes to charge a phone, but the innovation won’t be found in the Google Pixel 9 series. Instead, it’s coming from the newly resurgent Realme, which will unveil its Realme 320W SuperSonic battery charging system on August 14. Forget what you think is a fast-charging battery, because this seems to be taking it to a whole new level.

Realme has shared early details of its 320W SuperSonic charging system on several social networks. On Weibo in China, the company posted a short video claiming it will be number one in the world when it comes to charging speeds, while on X (formerly Twitter) it wrote: “Say goodbye to long wait times and hello to lightning-fast power” and that it will offer “the world’s fastest charging ever”. Bold claims, but what do we know for sure about the speeds?

We don’t know anything official yet. Recently, a leaked video surfaced showing a Realme smartphone being charged using the 320W SuperSonic charger, and it shot up to 17% charge in only 35 secondsWhile Realme’s SuperSonic charging will almost certainly not be able to maintain that pace for the entire charging cycle, it is very likely that it will outperform rival Redmi’s 300W HyperCharge charging system, which has been proven to be able to fully charge a 4,400mAh battery cell in around five minutes.

Realme’s 320W SuperSonic charging follows the brand’s 240W charging system introduced in 2023, which was able to charge a 4,600mAh battery in just under 10 minutes. This was made possible by a combination of GaN charging technology, dedicated USB cables, and various chipsets that handle everything from security to cooling. Expect even newer technologies and further advancements in the SuperSonic system.

When will Realme’s 320W SuperSonic charging system be available on a phone? This is where it gets complicated. The charging technology will be unveiled and likely fully demonstrated at a Realme event in China on August 14. However, this isn’t a phone launch, but a fan-centric gathering, so it will likely be more of a showcase of what’s to come. Additionally, Realme’s 240W charging isn’t available across the entire lineup, and Redmi’s HyperCharge hasn’t gotten past a demonstration either. For now, it’s probably less about when we’ll be able to use it ourselves, and more about what the engineers are doing to drastically reduce battery charging times. We’ll hear more about Realme’s new charging technology after the August 14 announcements.
