The OnePlus 8T’s 4500mAh battery takes 35 minutes to charge with Warp Charge 65

OnePlus’devices have been coming with some form of fast charging since 2016 when the OnePlus 3 and the OnePlus 3T were announced with Dash Charge as one of their headlining features. Dash Charge offered 20W wired charging speeds, which was fast at the time. Over the years, other companies started to catch up and offer even faster charging speeds. OnePlus then introduced Warp Charge 30 which brought the charging speeds up to 30W, starting with the OnePlus 6T McLaren Edition and more widely with the OnePlus 7 Pro. It’s 2020, though, and 30W charging can barely be considered fast now. With the upcoming OnePlus 8T, the company will be introducing Warp Charge 65, as we’ve been expecting.

As you may guess from its name, Warp Charge 65 offers even faster charging speeds than Warp Charge 30 with up to 65W of power. How fast is that, exactly? OnePlus is marketing its new tech with the slogan “a day’s power in 15 minutes” and claims that the OnePlus 8T will charge up to 58% in just 15 minutes and to 100% in just 35 minutes.

The company took to their forums to make the announcement, and they also shared a YouTube video teasing the new charging tech. OnePlus CEO Pete Lau also shared some additional details of Warp Charge 65 with PCMag. One of the key details mentioned in the interview is that the OnePlus 8T won’t support wireless charging like on the OnePlus 8 Pro, which OnePlus says would have required increasing the phone’s thickness to accommodate the wireless charging coils and other safety tech to make 30W wireless charging possible.

As you might expect, Warp Charge 65 is similar to OPPO’s 65W SuperVOOC 2.0, which is featured on devices like the OPPO Reno4 Pro and is a high amperage and low voltage charging solution. The OnePlus 8T features a dual-cell battery design with a total battery capacity of 4,500mAh, and both cells are charged at the same time. Charging two batteries instead of one at the same time allows for effectively doubling the charging speed without putting more stress on each battery. To keep charging safe, OnePlus says they added an encryption chip to the charger and cable as well as 12 temperature sensors in the phone so the OnePlus 8T can negotiate the right voltage/current combination. In addition, the phone itself has a “new heat dissipation system” to keep the charging temperature “at a comfortable level.”

With the move to Warp Charge 65, OnePlus is also changing the charging adapter design. The new charging adapter now comes with a USB-C port; previously, Dash Charge and Warp Charge 30 power bricks had a USB-A port which required the use of OnePlus’s USB-A to USB-C cable. OnePlus says the new adapter can charge other devices at up to 45W speeds via the USB Power Delivery spec, while the 8T itself can charge at up to 27W speeds using a different charger (up from 15W on older devices). The new adapter is also backward compatible with Dash Charge and Warp Charge 30, so you can use it to charge any older OnePlus smartphone that you may have.
