- The OnePlus 15 will have a 7,300mAh battery inside
- It beats the other flagship phones currently on the market
- The phone will launch in China on October 27
The official date for the grand OnePlus 15 unveiling has been set for Monday, October 27 (at least for the launch in China), and ahead of the event we’re continuing to get details of the specs and features this flagship phone will bring with it.
OnePlus has now confirmed on Chinese social platform Weibo (via Notebookcheck) that the OnePlus 15 will come with a massive 7,300mAh battery. Charging rates are set at 120W for wired and 50W for wireless, which are also both very impressive.
That giant battery capacity had been mentioned in earlier leaks, but now we know it’s coming. OnePlus has also gone on the record saying that we’ll see a Snapdragon 8 Elite Gen 5 chipset here, and a display with a maximum refresh rate of 165Hz.
In fact, there’s not much left that isn’t actually official. We’re still not certain about the screen size, but a 6.78-inch panel has been rumored. The same batch of leaks also pointed towards a triple-lens 50MP+50MP+50MP camera on the rear of the phone.

So how does that 7,300mAh battery capacity compare to the other top flagships at the moment? Very well, actually: the recently-launched iPhone 17 Pro Max, for example, has a battery capacity of around 5,088mAh (Apple never lists specific capacities).
As per Apple, that phone can last for 37 hours between charges when playing videos, so the OnePlus 15 might even exceed that. Real world battery life depends on a variety of factors of course – but the size of the battery definitely plays a big role.
The Samsung Galaxy S25 Ultra carries a 5,000mAh battery, while the Google Pixel 10 Pro XL has a 5,200mAh battery inside. The OnePlus 15 isn’t just beating these competing flagships in terms of battery capacity, it’s beating them by a clear margin.
We have seen phones with battery capacities as high as 33,000mAh in the past, so the OnePlus 15 won’t be a record breaker – but those big battery phones are overly bulky and impractical for day-to-day use as a consumer flagship.
