The upcoming OnePlus 15R will have a large battery, though not as massive as initially anticipated.

The brand's next affordable flagship will put a lot of its rivals to shame with a 7,400mAh cell.
OnePlus recently confirmed the 15R handset will feature a 7,400mAh battery. While this is technically true, the brand does not currently sell a phone in India with a larger battery.
However, the OnePlus Ace 6T in China includes an even larger 8,300mAh battery. The standard Ace 6, released there a month prior, featured a 7,800mAh battery.

The OnePlus 15R was expected to be the global version of the Ace 6T, which remains true for other specifications.
A 7,400mAh battery is not modest, exceeding the OnePlus 15’s 7,300mAh battery and outperforming the Samsung Galaxy S25 Ultra, Apple iPhone 17 Pro Max, and Google Pixel 10 Pro XL.
The upcoming Galaxy S26 Ultra is unlikely to reach 6,000mAh. However, the battery endurance may not align with its theoretical size.
The OnePlus 13R, for example, performed reasonably well in battery tests, but didn't crack the top 50 despite its 6,000mAh battery.
Other rumored OnePlus 15R specs include:
* Qualcomm Snapdragon 8 Gen 5 processor
* 165Hz display
* IP66/68/69/69K certifications
* OxygenOS 16 software
After battery expectations fell through, it may be best to await confirmation about other specs such as the 50 + 8MP dual rear camera, 16MP selfie camera, 100W charging, up to 16GB RAM, and 6.83-inch screen.
The IP ratings guaranteeing protection are impressive. The OnePlus 15R may also be among the first devices with a Snapdragon 8 Gen 5 chipset.
This is different from the Snapdragon 8 Elite Gen 5 inside the OnePlus 15. The 165Hz refresh rate also improves on the OnePlus 13R's 120Hz.
The 15R is scheduled to launch on December 17 in India and Europe, allowing for a fully informed decision.
If affordable and available in countries like the US, this device could become a global success.
