The Nothing Phone (4b) has the higher listed peak brightness and the longer software and security support commitments. Both are listed with a 6,000 mAh battery, a 120 Hz display, a 50 MP main camera with an 8 MP ultrawide, and a 16 MP front camera. In India, the most recent prices in the comparison sources sit between ₹31,499 and ₹31,999, and the gap between the two phones depends on the retailer and the source you check.
Specifications side by side

The realme panel is the larger and sharper of the two. Using the listed diagonal and pixel counts, the realme works out to roughly 450 pixels per inch and the Nothing to roughly 381 pixels per inch (our calculation from the listed figures). At normal viewing distances, that gap is noticeable mainly in text and fine detail.

Peak brightness runs the other way. Nothing lists 2,000 nits against realme’s 1,500 nits. Peak figures are measured under specific test conditions, usually on a small highlighted area, so they tell you how bright the screen can get in a bright-light situation rather than how it performs for everyday viewing. Neither listing says how the brightness was measured.
Cameras: matching megapixel counts, different disclosure
Both phones use the same rear pairing on paper: a 50 MP main camera and an 8 MP ultrawide. realme’s official India page identifies the main sensor as a Sony IMX896 with optical image stabilisation (OIS). The comparison source does not name the Nothing’s main sensor, so the two cameras cannot be compared at the component level from these sources.
Megapixel counts do not decide photo quality, which depends on the sensor, lens, processing and stabilisation. No side-by-side photo testing was done for this comparison, so no camera winner can be named. Judge both on sample photos taken in the lighting you use most.
Quick wins for a faster PC:

Both phones are listed with a 6,000 mAh battery, but the charging speeds differ sharply: 80W for the realme against 33W for the Nothing. realme’s official India page says the 80W adapter is included in the box. That makes the realme’s charging advantage real on paper, and it matters most if you often top up quickly.
Rank #2
- Snapdragon 8s Gen 3 chipset: The Realme GT6 is equipped with a powerful Snapdragon 8s Gen 3 processor, designed to easily handle high load scenarios in gaming, providing smooth multitasking performance and excellent energy efficiency. Users can flexibly control device performance between 50% and 100% by adjusting CPU and GPU performance settings to meet different needs.
- Ultra bright display technology: The GT6 uses cutting-edge luminescent materials to create an easy to read and visually stunning screen experience. Its ultra-high brightness display screen (up to 6000 nits) and 2160 Hz PWM dimming function not only improve viewing comfort, but also ensure the accuracy of color display.
- Top of the line Sony LYT-808 OIS camera: The GT6 is equipped with an industry-leading 1/1.4-inch large-sized sensor, providing unparalleled performance for night photography. With the HyperTone imaging engine, realistic colors and delicate light and shadow contrasts can be captured in both bright and dim environments. Super OIS technology further enhances image stability and clarity, improving the success rate of shooting.
- Iceberg Steam Cooling System: By combining 10014 square millimeters of 3D tempered dual VC heat dissipation plates and a 9-layer cooling structure, coupled with side full zone cooling design, GT6 achieves efficient and consistent high-performance gaming experience, while significantly reducing heat perception and ensuring temperature control during long-term gaming.
- Intelligent prediction and personalized advice: The built-in artificial intelligence can identify your usage habits, predict your needs, and provide accurate advice. For example, when you long press the text to book a hotel, the AI will automatically pop up a series of map prompts to help you quickly find the best route to your destination.
Battery endurance is a different question. The realme listing shows a PCMark battery result of 12h 57m, but the comparison page does not show a matching Nothing result. Nothing’s official product page describes the phone as having “our longest-lasting battery”. That is the company’s own claim, not an independent comparison, and it should be treated as marketing until it is tested against the realme under the same conditions.
Performance: what the listed numbers can and cannot show
The realme uses a MediaTek Dimensity 8350 Ultra, while the Nothing uses a Snapdragon 6 Gen 4. The listed peak clock speeds (3.35 GHz and 2.3 GHz) describe the maximum a core can reach. They do not show sustained performance, thermal behaviour or what the chip delivers in games. The realme’s AnTuTu score of 1,403,197 is a listing figure for that phone alone, and the comparison page has no Nothing Phone (4b) AnTuTu score to set beside it. No head-to-head speed result can be inferred from these numbers.
Software and update commitments
The realme ships with Android 15 and the Nothing with Android 16. The comparison source reports two years of OS updates and three years of security updates for the realme, and three years of OS updates and six years of security updates for the Nothing. These durations are reported by 91mobiles and have not been checked against each manufacturer’s current support terms. Because update policies can change and may differ by market, confirm the figures on the official realme and Nothing support pages before you base a purchase on them.
Price difference: dated, retailer-specific figures
Prices in this category move frequently, and the sources disagree. The table below lists what each source displayed in India.
| Source | Phone | Retailer shown | Price shown |
|---|---|---|---|
| 91mobiles comparison page (no update date given) | realme P3 Ultra | Flipkart | ₹31,999 |
| 91mobiles comparison page (no update date given) | Nothing Phone (4b) | Amazon | ₹31,499 |
| Smartprix (last updated 6 September 2026) | realme P3 Ultra | not stated | ₹31,999 |
| Smartprix (last updated 6 September 2026) | Nothing Phone (4b) | not stated | ₹31,890 |
Taken at face value, the gap is ₹500 on the 91mobiles figures and ₹109 on the Smartprix figures. Those two gaps come from different retailers and different dates, so they are not a like-for-like price difference. The sources also do not say whether each figure is a list price or a discounted price, and the storage configuration behind each figure should be checked before you compare.
Nothing’s official Malaysia store showed the 8+128GB Phone (4b) at MYR 1,499 when it was checked. That is a Malaysian price in a different currency, with different taxes and a different market mix, and it cannot be compared directly with the Indian rupee figures above.
Which phone suits which buyer
Choose the realme P3 Ultra if
- Fast charging matters to you, and you want the adapter included in the box.
- You want the larger, higher-resolution screen and faster UFS 3.1 storage on the listed configuration.
- You are comfortable with a shorter listed update window of two years for OS updates.
Choose the Nothing Phone (4b) if
- You prefer Nothing’s software experience and value the longer reported support period of three years for OS updates and six years for security updates, once you have confirmed it with Nothing.
- You care about the higher listed peak brightness for use in bright outdoor light.
- You are buying in a market where the Nothing is priced lower at the retailer you prefer.
Checks before you buy
- Confirm the RAM and storage configuration on the listing you are buying. The comparison uses 128 GB, and some listings and markets differ.
- Check the live price at the retailer you plan to use, and note the date. Do not compare figures from different retailers or dates as if they were the same.
- Check the warranty terms that apply in your country, including whether the seller is authorised.
- Check the update commitments on the official realme and Nothing support pages for your market.
- Check the official dimensions and weight. The comparison lists about 183 g for the realme, and no matching Nothing weight appears in the sources used, so weight should not be treated as a difference until you confirm both figures.
- Check what comes in the box. realme’s official India page lists an 80W adapter and a protective case; confirm the same for the listing you are buying.
All of the specifications and prices here are as reported by the sources named above at the dates given, so treat them as a starting point and confirm them before you buy.
