OnePlus 15 teased: Mammoth 7,300mAh battery & 120W charging, Oct 27 launch & new purple color!

Huge Glacier Battery: OnePlus has confirmed a 7,300 mAh battery on the upcoming OnePlus 15 ^[1] – a jump from the 6,000 mAh cell in the OnePlus 13. That makes it far larger than most flagships (roughly 40% bigger than Google’s 5,200 mAh Pixel 10 Pro XL and 46% bigger than a 5,000 mAh Galaxy S25 Ultra) ^[2]. OnePlus is even branding it a “Glacier Battery,” hinting at new silicon-carbon cell tech. With such capacity, analysts expect “two full days of usage might be within reach” ^[3].
Ultra-Fast Charging: Alongside the big battery, the OnePlus 15 will support 120W wired charging (branded “Super Flash Charge”) and 50W wireless charging ^[4] ^[5]. This beats the OnePlus 13’s 100W wired charging, although US models may still be limited to ~80W for safety ^[6]. OnePlus also confirms a bypass charging feature for safer charging of accessories. In one teaser, OnePlus boasted the combo as “the ultimate power and battery life combination,” designed to keep gamers going longer ^[7].
High-End Specs: The OnePlus 15 will be a true flagship under the hood. It’s confirmed to use Qualcomm’s new Snapdragon 8 Elite Gen 5 chipset, paired with a 6.78-inch OLED display at 165 Hz refresh rate ^[8]. This ultra-high-refresh screen (up from 120Hz on OnePlus 13) is a gaming-oriented upgrade – OnePlus even says the battery is meant to enhance “ultra-high-frame-rate gaming” experiences ^[9]. The phone will launch with OxygenOS 16 (Android 16) out of the box ^[10].
Launch Schedule: OnePlus has officially announced the OnePlus 15 will debut in China on October 27, 2025 at 7pm Beijing time (3am PT / 8am ET) ^[11]. This Chinese unveiling (alongside a new Ace 6 model) will reveal all specs, but the global launch will come later. Industry leaks suggest an international release about two weeks after – around mid-November (around Nov 13) ^[12]. (By comparison, the last OnePlus flagship launched in China in October 2024 but waited until January 2025 for a world release.)
Design & Colors: The OnePlus 15 sticks to the Sandstone-inspired style with tiny 1.15 mm bezels ^[13] and a simple camera array. It will ship in at least three finishes: the signature Sand (or “Sand Storm/Dune”) and Absolute Black, plus a new purple accent color. TechRadar saw OnePlus’ posts calling it “Misty Purple,” while other outlets translate it as “Fog Purple” or “Mist Purple” ^[14] ^[15]. (Note: there’s no OnePlus 14 – the company skips that number for superstitious reasons ^[16].)

OnePlus has highlighted that the new battery and charging suite are aimed at gamers and power users. As Android Central explains, OnePlus’ marketing touts the 7,300mAh cell as part of its “Glacier Battery” tech to enable longer gaming sessions. The company states the pack is “designed to enhance its ‘ultra-high-frame-rate gaming’ experience” ^[17]. In its own Weibo teaser OnePlus described the OnePlus 15 as “designed for ultra-high-frame-rate gaming” with the 7,300 mAh cell and “120W Super Flash Charge” ^[18].

In short, the OnePlus 15 looks to set new endurance benchmarks. Hadlee Simons at Android Authority calls the jump to 7,300 mAh a “significant upgrade” over the 6,000 mAh OnePlus 13 battery, and even a “gigantic upgrade” over most rivals ^[19]. Combined with 120W wired fast charging, this could allow days of mixed use on a charge. Of course, as Android Authority notes, US models have historically been capped at ~80W wired charging ^[20], so American buyers may see slightly slower speeds. Still, even at 80W the charging is extremely fast by any standard.

The October 27 China launch is drawing a lot of attention. OnePlus plans a webcast at 7pm Beijing time that day ^[21], where it will reveal full specs and pricing (Chinese-market) for both the OnePlus 15 and the mid-range OnePlus Ace 6. We already know several details: as mentioned, it will use the Snapdragon 8 Elite Gen 5 chip and a 165Hz 6.78″ OLED screen ^[22], along with its giant battery and fast charging. The company has also confirmed this model will drop its Hasselblad camera partnership and use OnePlus’ in-house “DetailMax Engine” for imaging. Early previews note an all-50MP triple camera array, support for 8K/120fps video recording, and 1.15mm slim bezels ^[23] ^[24].

International customers won’t have to wait too long after the Chinese debut. OnePlus already said the phone will come to “the rest of the world” – and Android Central reports leaks pegging an international launch around November 13 ^[25]. If true, that would mean roughly two weeks after the Chinese event (much faster than the 3-month wait for its predecessor). Once global pricing is set, the OnePlus 15 will compete directly with this fall’s other flagships.

In summary, OnePlus is aggressively pushing battery life and charging as the OnePlus 15’s headline features. Industry sources highlight that no current Android phone matches a 7,300mAh pack with 120W charging. As 9to5Google puts it, OnePlus is promising “the year’s only ‘120W Super Flash Charge’” paired with this monster battery ^[26]. For fans of long-lasting phones, this looks to be the biggest news coming out of the October launch – just ahead of the official reveal on Oct. 27.

Sources: Verified specs and dates were announced by OnePlus on Weibo and reported by outlets like Android Authority, Android Central, TechRadar and 9to5Google ^[27] ^[28] ^[29] ^[30], among others. Each of the above points is confirmed by these sources.
