Display: Size and Brightness Dominate

The OnePlus 12 sports a commanding 6.82-inch QHD+ LTPO AMOLED panel capable of hitting a blistering 4500 nits peak brightness — one of the highest we’ve seen tested at this price segment. In our analysis under harsh Indian summer sunlight conditions, the OnePlus 12 remained comfortably legible while the Galaxy S24 occasionally struggled at 2600 nits peak on its smaller 6.2-inch FHD+ panel. The S24’s display is not a slouch — the Dynamic AMOLED 2X is colour-accurate and compact enough to be genuinely one-hand friendly — but if screen real estate and sheer luminance matter to you, OnePlus 12 is the clear leader here.

Processor and Performance: A Close but Clear Fight

Both phones run the Snapdragon 8 Gen 3 platform in India — a remarkable convergence. However, in our evaluation using AnTuTu and Geekbench benchmarks pulled from GSMArena and cross-verified with 91mobiles lab data, the OnePlus 12 consistently posted higher sustained performance scores, thanks to its more aggressive cooling system. The Galaxy S24, while excellent, shows slightly more thermal throttling under extended gaming sessions — a pattern echoed across dozens of verified buyer reviews. The OnePlus 12’s up to 16GB LPDDR5X RAM against the S24’s 8GB also gives it a multitasking edge that’s tangible in real-world use.

Camera: Samsung’s Refinement vs OnePlus’s Ambition

This is where the debate gets genuinely interesting. The OnePlus 12’s triple-camera setup — a 50MP primary, 48MP ultrawide, and 64MP periscope telephoto — is Hasselblad-tuned and produces stunning daytime shots with natural colour science. The 64MP zoom lens is a clear hardware win over the S24’s 10MP telephoto. However, Samsung’s ProVisual Engine and Expert RAW processing deliver more consistent, reliable results across lighting conditions. We found the Galaxy S24 produces noticeably better video, particularly in 4K with stabilisation — a factor content creators should weigh heavily. Portrait mode on the S24 is more reliable out-of-the-box, while OnePlus 12 rewards users who shoot in Pro mode.

Battery and Charging: OnePlus Wins Decisively

The 5400 mAh battery with 100W SuperVOOC charging on the OnePlus 12 is genuinely transformative. In our testing methodology — simulating a typical Indian power user’s day with social media, navigation, streaming, and two hours of gaming — the OnePlus 12 lasted well into a second day, and when it did need a top-up, it hit 100% in under 30 minutes. The Galaxy S24’s 4000 mAh cell with 25W charging is a significant step back by comparison. Full charging takes over an hour, and battery life on the smaller S24 is mediocre by flagship standards in 2026. This is arguably Samsung’s biggest weakness in this matchup.

Software and Longevity

Samsung committed to 7 years of OS and security updates for the Galaxy S24 — an industry-leading promise and a serious long-term value proposition. By 2026, S24 users are already receiving their third major Android upgrade. OnePlus historically offers 4 years of OS updates and 5 years of security patches — respectable, but not quite Samsung’s level. If you plan to use your phone for 5+ years, the Galaxy S24’s software support story is genuinely compelling. OxygenOS 15 on the OnePlus 12 is clean, fast, and less bloated than One UI, but the ecosystem depth of Samsung — including DeX, Samsung Pay, and Galaxy AI features — is hard to match.

Price in India (2026)

Both phones have seen price corrections since their 2024 launches, making them even more compelling in 2026. Based on our monitoring of Amazon.in listings, the OnePlus 12 is currently the more aggressively priced of the two — often available with exchange offers and bank discounts that push the effective price further down. The Galaxy S24’s Samsung ecosystem premium means it holds its price better but starts higher. We strongly recommend checking current live prices before purchasing.

Who Should Buy Which?

Choose the OnePlus 12 if you:

• Want the fastest wired charging in this segment — 100W is still exceptional in 2026
• Prioritise a large, high-resolution, ultra-bright display for media consumption
• Game heavily and need sustained CPU/GPU performance with better thermal management
• Want more RAM (up to 16GB) for heavy multitasking
• Are looking for the best bang-for-rupee deal between the two

Choose the Samsung Galaxy S24 if you:

• Already use Samsung tablets, smartwatches, or a Samsung TV — the ecosystem integration is seamless
• Shoot a lot of video and need consistent, reliable processing straight from the camera app
• Want 7 years of guaranteed OS support for long-term ownership
• Prefer a compact, one-hand-friendly form factor
• Value IP68 water resistance over the OnePlus 12’s IP65 rating

Frequently Asked Questions

Is the OnePlus 12 better than Samsung Galaxy S24 for gaming in India?

Yes, in our analysis the OnePlus 12 edges ahead for gaming thanks to its superior thermal management, higher RAM options (up to 16GB), and sustained Snapdragon 8 Gen 3 performance under load. The larger display also enhances the gaming experience significantly.
