July 17, 2025 — The tech rumor mill is buzzing again! Well-known tipster Yogesh Brar has spilled key specifications and launch timelines for two of 2025’s most anticipated Android flagships: the OnePlus 15 and iQoo 15. According to Brar, both phones will pack Qualcomm’s next-gen powerhouse chipset and aim to redefine battery performance in their segments.

The OnePlus 15: Refining the Speedster Formula

Brar claims the OnePlus 15 will retain core DNA while pushing boundaries:

Chipset: Snapdragon 8 Gen 4 (4nm)
Display: 6.78-inch 2K LTPO AMOLED (1–120Hz adaptive refresh)
Cameras: Triple rear setup—50MP main (Sony IMX890), 50MP ultra-wide, and a 64MP periscope telephoto with 3x optical zoom.
Battery & Charging: 5,500mAh cell with 100W wired and 50W wireless charging—OnePlus’ largest battery yet.
Design: Slimmer bezels, upgraded Alert Slider, and IP68 rating.

This positions the OnePlus 15 as a "display and endurance king," potentially outclassing its predecessor’s 5,000mAh pack.

iQoo 15: Gunning for Speed Demons

The iQoo 15, meanwhile, targets performance enthusiasts:

Chipset: Same Snapdragon 8 Gen 4 as OnePlus 15.
Display: 6.7-inch Full HD+ AMOLED with 144Hz refresh rate.
Cameras: 50MP primary (with gimbal OIS), 8MP ultra-wide, 12MP telephoto (2x zoom).
Battery & Charging: 5,000mAh battery with 120W HyperCharge support.
Extras: Dedicated gaming chip, vapor chamber cooling.

Notably, iQoo’s focus remains on raw speed—both in display fluidity and charging tech.

Shared DNA: Snapdragon 8 Gen 4 and Timelines

Both flagships will reportedly debut Qualcomm’s Snapdragon 8 Gen 4, expected to feature Oryon CPU cores and a potent Adreno 830 GPU. Brar emphasizes that thermal management will be critical given the chip’s rumored performance leap.

Launch Timeline:

Global Debut: January 2025 (aligning with CES in Las Vegas).
Market Rollout: China and India first, followed by Europe/North America by February.

This pits both devices against Samsung’s Galaxy S25 series, setting up a fierce early-2025 flagship battle.

Analysis: Betting Big on Battery Wars

The specs suggest brands are prioritizing battery life over slim designs:

OnePlus 15’s 5,500mAh is a 10% jump from the OnePlus 14.
iQoo’s 120W charging could refuel 80% in under 15 minutes.

Camera strategies diverge sharply though—OnePlus leans into high-res zoom, while iQoo optimizes for stability and speed.

Caveats and Context

As with all leaks, these details aren’t official. Brar has a solid track record (correctly predicting OnePlus 14 specs), but OEMs often tweak prototypes. Pricing remains unknown, though insiders hint at minor hikes due to the Snapdragon 8 Gen 4’s cost.

Final Thoughts

If Brar’s intel holds, 2025’s flagship race starts with a bang. The OnePlus 15 could become an all-rounder favorite, while the iQoo 15 may dominate mobile gaming. One thing’s clear: January can’t come soon enough!
