OnePlus 15s Gets BIS Certified – Compact Flagship with Snapdragon 8 Elite Gen 5 and 7500mAh Battery Incoming?

Hey everyone, December 19, 2025 – fresh off the OnePlus 15R launch, there's already buzz about the next OnePlus phone. The OnePlus 15s (model CPH2793) just popped up on India's BIS certification database, which almost always means an India launch is right around the corner.

This is shaping up to be OnePlus's compact flagship – think the successor to the 13s, but loaded with top-tier specs. Leaks from reliable tipsters like @Gadgetsdata and others are painting an exciting picture: a small phone with flagship power, insane battery, and a camera focused on zoom. Let's break down what we know so far and my thoughts on it.

OnePlus 15s Gets BIS Certified

The Key Leaked Specs

  • Display: ~6.31-6.32-inch flat OLED (BOE X3 panel), 1.5K resolution, 165Hz refresh rate – super smooth, symmetrical slim bezels, perfect for one-hand use.
  • Processor: Snapdragon 8 Elite Gen 5 – Qualcomm's absolute top chipset, same as the main OnePlus 15 flagship. Beastly performance, great gaming, and AI features.
  • Battery: Massive ~7500mAh with 100W fast charging – in a compact body? That's wild endurance, potentially 2 days easy.
  • Cameras:
    • Rear: 50MP Sony IMX906 (or possibly 200MP Samsung HP5 main) + 50MP Samsung JN5 telephoto (good zoom capabilities)
    • No ultrawide mentioned (a potential downside)
    • Front: 32MP
  • Other Highlights:
    • Metal frame for premium feel
    • IP68/IP69 dust/water resistance
    • Ultrasonic in-display fingerprint scanner
    • Around 8.5mm thick
    • OxygenOS 16 based on Android 16

It's likely the global/India version of the China-exclusive OnePlus 15T.

Why This Could Be a Big Deal

Compact flagships are rare these days – most phones are pushing 6.7-6.8 inches. A 6.3-inch screen with flagship chip, huge battery, and solid cameras? That's the dream for people who want power without the bulk. One-hand usage, pocket-friendly, but no compromises on performance or endurance.

The 7500mAh battery in such a small phone is impressive engineering (probably silicon-carbon tech like the 15R). Paired with the efficient Snapdragon 8 Elite Gen 5, this could be a battery champion.

Camera-wise, focusing on main + telephoto (no ultrawide) makes sense for a compact phone – saves space, prioritizes zoom for portraits/distant shots. If the main is 200MP, expect crazy detail.

Potential Downsides

  • No ultrawide? That's a miss for landscapes or group shots – rivals like iPhone or Pixel minis usually have it.
  • Price: Leaks suggest ₹60,000–₹65,000 bracket. That's premium territory, competing with the base OnePlus 15 or Vivo X200. Justified by the specs, but might feel steep for a "mini" model.
  • Launch timeline: BIS is early, so probably Q1 or mid-2026 (following the 13s pattern).

My Thoughts

I'm genuinely excited – I miss compact phones that don't skimp on specs. The OnePlus 13s was great, but this jumps to the latest chip and even bigger battery. If OnePlus prices it right (under ₹60k with offers), it could dominate the "small flagship" niche.

Perfect for gamers wanting portability, power users tired of big phones, or anyone who values battery life above all. The lack of ultrawide stings a bit, but the telephoto might make up for it.

What do you think – would you buy a compact flagship at 60-65k? Hyped for the battery, or waiting for more camera details? Drop your takes in the comments!

Launch should be soon-ish – I'll keep you updated as more leaks drop.
