All rear cameras in the OnePlus 15 have been downgraded compared to the OnePlus 13

The main camera has been downgraded from LYT808 (1/1.4") to IMX906 (1/1.56"), the ultra wide from JN5 (1/2.75") to OV50D (1/2.88"), and the telephoto from IMX882 (1/1.95") to JN5 (1/2.75"); for the telephoto, the OnePlus 13’s IMX882 had a 50cm minimum focus distance, while the OnePlus 15’s JN5 has 30cm, which is still insufficient for quality tele macro shots at 85mm, where around 15cm is needed

OnePlus used the older OV50D (1/2.88") for the ultra wide instead of the newer OV50M (1/2.88") used in the Xiaomi 17 series; sensor quality ranks as JN5 > OV50M > OV50D. Notably, the realme GT8 Pro also uses OV50D for its ultra wide, suggesting shared resources within the OPPO group

The front camera is now an IMX709 (1/2.74") versus the OnePlus 13’s IMX615 (1/2.74"); both are comparable, but the OnePlus 15 adds autofocus for the front camera

However, improved image processing in the OnePlus 15 may help mitigate the impact of these hardware downgrades to some extent

The OnePlus 15 features symmetrical super-linear dual stereo speakers, each emitting sound in the same direction for fuller, more balanced stereo sound

The OnePlus 13 uses AAC 1012H top speaker (10x12=120mm²) and AAC 1115E bottom speaker (11x15=165mm²)

If the OnePlus 15 features symmetrical speakers, it likely upgrades the top speaker to an 1115 specification, as the realme GT8 Pro uses dual 1115E speakers

The resolution is the same as its big brother Xiaomi 17 Pro Max, which is 2608*1200. The value does not look that high because the same super pixel technology is used. To make a long story short, each pixel has independent red, green and blue sub-pixels. There is no loss without borrowing adjacent sub-pixels. Therefore, the clarity is better than the diamond arrangement with the same resolution.

Top speaker adopts the 1115F (11x15=165mm²) specification of Goertek's full metal package. The interior is filled with N'Bass® acoustic enhancement material. Compared with 1014D (10x14=140²) of the previous generation K80 Pro, it has been upgraded.

The core specification of the bottom speaker is the same as the top 1115F, but the supplier has been changed to AAC Technologies. The interior is also filled with N'Bass® acoustic enhancement material.

The upper and lower two 1115F full-range speakers are matched with the 1620C on the back. The woofer forms a 2.1 - channel three-speaker system with BOSE's dual-style tuning.
