1. Design & Build
- OnePlus 13:
- Bigger footprint: 6.82″ display.
- Uses super-ceramic glass (Crystal Shield) for durability.
- Water/dust resistance: IP68 / IP69 (very good).
- Slightly heavier (about 210g) according to specs.
- OnePlus 15:
- Slightly smaller screen: ~6.78″.
- Very thin bezels, modern design with a squared camera island.
- High durability / premium materials: supposed IP68+ rating too.
- A little lighter or similar weight (depending on components).
Verdict (Design): If you like a larger screen, the 13 wins. But if you prefer something more compact yet premium with a modern look, the 15 is appealing.
2. Display
- OnePlus 13:
- 6.82″ LTPO AMOLED display.
- 1-120 Hz refresh rate.
- Very bright (PhoneArena measured peak, etc.).
- OnePlus 15:
- 6.78″ AMOLED, but with a much higher refresh rate: 1-165 Hz according to leaks/reviews.
- Very high brightness reported.
- More fluid animations, especially for gaming.
Verdict (Display): The 15 is more future-proof with its 165 Hz panel — great for gamers or users who want super smooth UI. But 13’s screen is still very good for daily use with 120 Hz.
3. Performance / Processor
- OnePlus 13:
- Uses Snapdragon 8 Elite (3 nm) according to its spec sheet.
- Very capable for multitasking, gaming, and heavy apps.
- OnePlus 15:
- Uses Snapdragon 8 Elite Gen 5 (newer / more powerful) according to spec comparisons.
- Better CPU and GPU performance, likely more efficient, better thermals.
Verdict (Performance): OnePlus 15 clearly has the edge in raw power and efficiency. If you want a faster phone or are a power user or gamer, 15 is better.
4. Memory / Storage Options
- OnePlus 13:
- High RAM versions: up to 24 GB RAM (according to its spec sheet) for super-heavy multitasking.
- Storage: uses UFS 4.0.
- OnePlus 15:
- According to spec leaks, offers 12 GB up to 16 GB LPDDR5X.
- Storage: UFS 4.1 (a bit faster than 4.0).
Verdict (Memory): Both phones give very good memory options. If you need insane RAM, the 13’s top variant might be better, but 15 is very balanced for most users.
5. Battery & Charging
- OnePlus 13:
- Battery: 6,000 mAh (silicon-carbon).
- Charging: 100W wired, 50W wireless (according to its specs).
- OnePlus 15:
- Much bigger battery: 7,300 mAh.
- Charging: 120W wired (fast) + 50W wireless (leaks / spec sites).
- According to 91Mobiles, despite big battery, it can charge from 20% to 100% in about 30 minutes.
Verdict (Battery): OnePlus 15 wins big here. The battery capacity and very fast charging make it ideal for heavy users, gamers, or people who don’t like plugging in often.
6. Cameras
- OnePlus 13:
- Triple 50 MP rear setup: main (Sony LYT-808), periscope telephoto, and ultra-wide.
- Known for Hasselblad tuning (color science, photo quality).
- Selfie: 32 MP (as per some spec sources).
- OnePlus 15:
- Also has three 50 MP cameras (main + ultra-wide + longer telephoto).
- Periscope is slightly improved: reports of 3.5x zoom on OnePlus 15 vs 3x on 13.
- According to leaks/sources, OnePlus 15 has dropped the old Hasselblad branding and might use a new DetailMax Engine for image processing.
Verdict (Camera): Very close. If you like reliable color tuning and proven camera system, 13 is still excellent. But for better zoom and newer image processing, 15 could be slightly more advanced — though not necessarily a huge leap.
7. Software & Features
- OnePlus 13:
- Comes with Android 15 + OxygenOS 15 (per spec sheet).
- Very mature and stable software.
- OnePlus 15:
- Likely ships with Android 16 (or newer) — according to spec comparisons.
- Newer software means longer update window, possibly better AI / system optimizations.
Verdict (Software): 15 has an advantage because of newer OS and future updates. But 13 will still be reliable for a while.
8. Price & Value
- According to Wiredify, OnePlus 15’s starting price in India is ~ ₹72,999 for the base model.
- The OnePlus 13 is slightly cheaper in some markets depending on its storage / RAM variant.
- Considering performance, battery, and features, the 15 is more “future-proof”, but the 13 might give better value for power users who don’t need the absolute latest.
9. Who Should Choose Which? (Use Case)
- Pick OnePlus 13 If You:
- Want a large, high-quality screen (6.82″)
- Prefer Hasselblad-tuned camera
- Do heavy multitasking (RAM variants, larger storage)
- Want fast charging + reliable battery, but don’t mind charging more often than 15 users
- Pick OnePlus 15 If You:
- Need longer battery life (7300 mAh is beast)
- Want ultra-high refresh rate (165 Hz) for gaming / smoothness
- Plan to keep the phone for several years — newer chip + software updates
- Want better zoom telephoto performance (3.5x)
- Like newer design + possibly better image processing
Final Verdict
- OnePlus 13 is a well-balanced, powerful flagship — great performance, good camera, and reliable battery.
- OnePlus 15 is a performance-plus phone — bigger battery, more modern display, slightly better zoom, and future-ready.
If you already own the 13, it’s not absolutely necessary to upgrade unless you really value the battery boost and smoother display of the 15. But if you’re buying now, OnePlus 15 could be a better long-term pick — especially for gamers and power users.
