The OnePlus 13 will launch in China on Halloween, and the company has been gradually teasing various features and specs on Chinese social media site Weibo over the past few weeks.

Today, the company gave us an early treat, revealing that the OnePlus 13 will officially feature a massive 6,000 mAh glacier battery, 600 mAh more than the OnePlus 12's 5,400 mAh.

The Glacier battery was announced this summer when the Chinese company unveiled the Ace 3 Pro. The battery uses a new “silicon carbon anode” technology that allows a 6,100 mAh battery cell to be packed into the same space as a 5,000 mAh cell.

In contrast, next year's Samsung Galaxy S25 Ultra is rumored to retain the 5,000 mAh found in the Galaxy S24 Ultra. However, the S24 Ultra is on our list of best phone battery durations, with a result of 16 hours and 45 minutes in our battery tests. Samsung is focused on maximizing the use of repetitive components through software and chip efficiency. That said, there are rumors that the battery may be larger to accommodate Qualcomm's recently announced Snapdragon Elite chip (which the OnePlus 13 will also feature).

OnePlus has reaffirmed that the phone will have 100W of wired charging. In addition, it will also feature 50W wireless charging; it appears that a OnePlus case with magnetic charging capability will be required to take advantage of the 50W wireless charging.

OnePlus offers a 50W charging accessory and a 5,000 mAh magnetic power bank that the company claims works with the iPhone.

The new phone is expected to get some new technology and slight design changes, but the other big feature that will likely take advantage of the high-power battery is the upgraded OxygenOS 15, which went into beta on October 30 and should be updated on the phone soon .

The OnePlus 13 will be available in China on October 31. This is an earlier release than usual, as new phones are usually announced in December. Typically, global releases take place several months later. As early as January, the OnePlus 13 is expected to be released worldwide as early as January, possibly February.
