The Nothing Phone (4a) Pro is the larger-screen alternative, and Nothing promotes its three-camera system with a 140x ultra-zoom claim. There is no reliable same-market, equivalent-configuration price pair here, so a single “price difference” would be misleading: OPPO’s detailed specifications are for India, while the observed Nothing price is from its UK storefront.
At a glance: compact camera phone or larger display?
Choose based on the trade-off that matters most to you: the Reno15 Pro Mini is the smaller handset on the available specifications, while the Phone (4a) Pro has the larger listed screen. OPPO’s India specifications give its phone a 200MP main camera, 50MP telephoto, 50MP ultrawide and 6,200mAh typical battery. Nothing’s UK page promotes a three-camera system and its own “World’s first 140x ultra zoom*” claim; detailed specifications below come from 91mobiles, not a full technical table on Nothing’s page.
- Consider OPPO if you want the smaller display and a stated 3.5× optical telephoto camera, or need the listed 12GB/256GB and 12GB/512GB configurations.
- Consider Nothing if the larger listed 6.83-inch display appeals to you and you value the advertised zoom range. Treat its 140x figure as a manufacturer claim, not as optical zoom or proof of image quality.
- Compare locally before buying: prices, configurations and availability shown by these sources are not like-for-like across countries.

Nothing’s figures in the table are secondary-source specifications and should be checked against the relevant country’s current product specifications before purchase. Display measurements and camera megapixels describe hardware, not image quality; battery capacity and charging ratings do not establish which phone lasts longer in ordinary use.
Display and physical size
The screen-size difference is the most straightforward practical distinction. OPPO specifies a 16.05cm display at 2640 × 1216 with a refresh rate up to 120Hz; its 8 January 2026 launch announcement calls it 6.32 inches. 91mobiles lists the Nothing at 6.83 inches, 1260 × 2800 and 144Hz. Those Nothing values are not confirmed by the official UK page cited here.
#1 Best Overall
- 6.57 inches, AMOLED, 1B colors, 1080 x 2372 pixels
- 256GB Storage, 8GB RAM, microSDXC
- Android 16, ColorOS 16, Qualcomm SM6450 Snapdragon 6 Gen 1 (4 nm), Octa-core (4x2.2 GHz Cortex-A78 & 4x1.8 GHz Cortex-A55)
- Rear: 50 MP, f/1.8, 26mm (wide), 1/1.95", 0.8µm, PDAF, OIS, 8 MP, f/2.2, 16mm, 112˚ (ultrawide), 1/4.0", 1.12µm, 2 MP (macro), Front: 50 MP, f/2.0, 100˚, 18mm (ultrawide), AF
A smaller display can make a phone easier to handle for people who prefer a compact handset. A larger panel offers more screen area for reading, video and multitasking, but screen size alone does not tell you how comfortable the whole device feels in your hand or pocket. If physical dimensions matter, compare the exact models in person or confirm the measurements from the manufacturer’s current page for your country.
Camera systems and zoom claims
OPPO: a clearly specified trio
OPPO’s India specifications list a 200MP main camera with two-axis optical image stabilization (OIS), a stabilized 50MP telephoto and a 50MP ultrawide. The launch announcement describes the telephoto as 3.5× optical zoom. The front camera is 50MP with a 100° field of view, and OPPO lists 4K recording up to 60fps for both front and rear cameras.
Rank #2
- 6.57 inches, AMOLED, 1B colors, 1080 x 2372 pixels
- 256GB Storage, 8GB RAM, microSDXC
- Android 16, ColorOS 16, Qualcomm SM6450 Snapdragon 6 Gen 1 (4 nm), Octa-core (4x2.2 GHz Cortex-A78 & 4x1.8 GHz Cortex-A55)
- Rear: 50 MP, f/1.8, 26mm (wide), 1/1.95", 0.8µm, PDAF, OIS, 8 MP, f/2.2, 16mm, 112˚ (ultrawide), 1/4.0", 1.12µm, 2 MP (macro), Front: 50 MP, f/2.0, 100˚, 18mm (ultrawide), AF
Nothing: headline zoom versus verified detail
Nothing’s UK product page advertises a Sony-sensor, three-camera system and the phrase “World’s first 140x ultra zoom*.” That is Nothing’s marketing claim; the page text cited here did not expose the accompanying asterisk disclaimer. It should not be read as 140× optical zoom. 91mobiles reports a 50MP main camera, 50MP periscope telephoto and 8MP ultrawide, but those figures are secondary reporting rather than a specification table from Nothing.
Megapixel counts and maximum zoom claims cannot settle which phone takes better photos. The supplied sources do not provide a controlled image-quality comparison, so match camera choices to the lenses and features you actually use rather than treating the headline numbers as a quality ranking.
Rank #3
- 6.83 inches, AMOLED, 1B colors, 1272 x 2800 pixels
- 512GB Storage, 12GB RAM
- Android 15, ColorOS 15, Mediatek Dimensity 8450 (4 nm), Octa-core 3.25 GHz
- Rear: 50 MP, f/1.8, 24mm (wide), 1/1.55", PDAF, OIS, 50 MP, f/2.8, 80mm (periscope telephoto), PDAF, OIS, 3.5x optical zoom, 50 MP, f/2.0, 16mm, 116˚ (ultrawide), AF, Front: 50 MP, f/2.0, 21mm (wide), AF
Battery capacity and charging
OPPO rates the Reno15 Pro Mini battery at 6,200mAh typical and 6,035mAh rated, with charging up to 80W SUPERVOOC. 91mobiles lists 5,400mAh and 50W charging for the Nothing. These are specifications from different sources, not a comparable battery-life test. Screen size, software, signal conditions, workload and charging setup all affect the experience, so the capacity figures alone do not establish a runtime winner.
Configurations, price and the meaning of “price difference”
A defensible current price difference requires prices for both phones in the same country and comparable memory/storage configurations. The available figures do not meet that test:
Rank #4
- 6.59 inches, AMOLED, 1B colors, 1256 x 2760 pixels
- 512GB Storage, 8GB RAM
- Android 16, ColorOS 16, Qualcomm SM7750-AB Snapdragon 7 Gen 4 (4 nm), Octa-core (1x2.8 GHz Cortex-720 & 4x2.4 GHz Cortex-720 & 3x1.8 GHz Cortex-520)
- Rear: 50 MP, f/1.8, 26mm (wide), PDAF, OIS, 50 MP, f/2.8, 80mm (telephoto), PDAF, OIS, 3.5x optical zoom, 8 MP, f/2.2, 15mm, 116˚ (ultrawide), 1/4.0", 1.12µm, AF, Front: 50 MP, f/2.0, 18mm (ultrawide), AF
| Price observation | What it represents | How to interpret it |
|---|---|---|
| £519 | Nothing UK storefront display for the selected Silver 8GB/128GB configuration, observed 4 October 2026. Nothing Phone (4a) Pro UK page | A page price for that selection at the time accessed; check the live page for current availability and price. |
| ₹59,999 for OPPO; ₹46,498 for Nothing | India Amazon references displayed by 91mobiles, observed 4 October 2026. 91mobiles comparison | Volatile secondary-page observations, not live retailer verification. The source does not establish an equivalent configuration pair for these figures. |
Do not subtract the UK storefront amount from the India references or treat the figures as a lasting price gap. Before choosing, check your country’s retailer listings for the same storage tier, confirm the precise model and any promotion, and compare the final price including applicable taxes and delivery.
