The OPPO Reno15 5G is the stronger fit if you want a higher-resolution display, a larger stated battery and faster wired charging; the Nothing Phone (4b) gives you a larger screen and a published software-support promise. Their prices depend on market, configuration and date, so compare live listings for the exact variants before buying.
Which phones are being compared?
This comparison is between the base OPPO Reno15 5G and the Nothing Phone (4b). Reno15 Pro-family specifications do not apply to the base Reno15. OPPO says specific release dates and prices are set through local-market announcements, so there is no single universal Reno15 price: OPPO’s global Reno15 series announcement.

Display, charging and battery: the practical differences
Screen size and resolution
The 91mobiles listing describes Phone (4b) as having the larger screen at 6.77 inches, while Reno15’s listed panel is 6.59 inches. It gives Reno15 the higher resolution: 1256 × 2760 versus 1080 × 2344. Both are listed at 120 Hz. That points to a trade-off between a physically larger Phone (4b) screen and more pixels on the Reno15 listing; it does not establish which display looks better in real use.
Battery capacity and charging
OPPO India specifies a 6,500 mAh battery and 80W wired SUPERVOOC charging for the base Reno15. The comparison listing gives Phone (4b) a 6,000 mAh battery and 33W charging. Capacity and charging wattage alone do not establish real-world battery life or charge times, and no like-for-like test of these two phones is established here.

Cameras and performance
Camera hardware
The 91mobiles listing gives the Reno15 and Phone (4b) 50 MP and 16 MP front cameras, respectively. OPPO India separately describes a 50 MP ultra-wide selfie camera for the base Reno15 and a 50 MP telephoto portrait camera among the Reno15 series capabilities. Because the global Reno15 lineup includes multiple variants, verify that a claimed camera is present on the specific base-model SKU in your market. Megapixel counts do not establish image quality.
Chipset and benchmark evidence
OPPO India identifies Snapdragon 7 Gen 4 in the base Reno15. Its reported AnTuTu score of 1.66 million applies to Reno15 Pro and Reno15 Pro Mini, not the base Reno15. The cited comparison listing does not provide a Phone (4b) benchmark and says it had yet to review that phone, so these sources do not establish a direct performance winner. Avoid using the Pro-family score to compare the two base models.

Software support and launch configurations
Nothing says Phone (4b) launched with Nothing OS 4.1 based on Android 16, three years of Android updates and six years of security patches. Those are Nothing’s stated support terms in its launch post; the cited OPPO India announcement does not give a comparable Reno15 support period. Nothing’s India launch configurations were 8 GB + 128 GB and 8 GB + 256 GB, so make sure any price comparison uses the storage tier you actually want.

Nothing’s launch post lists launch prices for the 8 GB + 128 GB Phone (4b) of £299, ₹29,999 and €329, plus an India-only 8 GB + 256 GB variant at ₹33,699. These are launch prices, not current quotes; the post also describes effective India pricing that includes bank and exchange offers, which should not be confused with the listed launch price. OPPO’s global announcement directs readers to local market announcements for Reno15 release dates and pricing.
Which one should you choose?
- Choose Reno15 if the India-announced 6,500 mAh battery and 80W wired charging, or its higher listed screen resolution, matter more to you—and the exact local configuration fits your budget.
- Choose Phone (4b) if you prefer its larger listed display, want Nothing’s published three-year Android and six-year security-patch support terms, or find its exact storage configuration at a better live price.
- Compare before deciding if your priority is camera quality, sustained performance or battery endurance. The available specifications do not substitute for controlled, comparable tests of these exact phones.
For either phone, compare the same market, RAM and storage tier, then check the seller’s current price and stock. The ₹ figures from a retailer snapshot and the launch prices above answer different questions and should not be treated as equivalent offers.
