Display: larger and faster versus AMOLED

The reported Redmi 15 panel is 0.13 inches larger diagonally and refreshes at up to 144 Hz, compared with the Phone (4b)’s 120 Hz. The Phone (4b) uses Super AMOLED, which Nothing confirms on its product page; the Redmi is listed as an IPS LCD. Panel technology, brightness, colour tuning, and software matter alongside resolution and refresh rate, so these figures alone do not establish which screen looks better to you.

Battery: compare the region-specific Phone (4b) version

The comparison lists a 7,000 mAh Redmi 15 battery and a 6,000 mAh Phone (4b) battery. Nothing’s product page says the Phone (4b) has a 5,200 mAh battery generally and a 6,000 mAh capacity in India. Match the exact regional variants before treating the capacity figures as a direct comparison. Capacity also does not establish real-world runtime: no independent battery-life test comparing these two phones is cited here.

Cameras: Phone (4b) adds a reported ultrawide lens

The available specifications list a 50 MP main camera for each phone. For the Phone (4b), they also identify an 8 MP ultrawide camera; Nothing describes that camera as having a 119° field of view. That gives the Phone (4b) a reported extra rear-camera perspective, but megapixel counts and lens coverage do not establish image quality. No hands-on camera comparison is available here.

Performance, memory, and software need variant checks

The chipset, RAM, storage, and Android-version entries above come from 91mobiles and may be specific to the listed configurations. The comparison does not provide matching benchmark results for both phones, so it cannot establish which is faster. Check the precise RAM/storage option and software version shown for the seller’s device; do not assume the listed configuration applies in every country.

Which phone should you choose?

  • Consider the Redmi 15 if the live price is your priority and you prefer the larger listed screen and higher refresh rate. Confirm battery capacity, memory configuration, and warranty for the exact variant.
  • Consider the Nothing Phone (4b) if you prefer an AMOLED panel or want the reported ultrawide rear camera. Check the market-specific battery version and whether its higher local price fits your budget.

Before ordering either model, compare the total local price for the same storage tier, confirm the model and seller, and review warranty and return coverage. The listed prices and specifications are not universal guarantees.

Charging and box contents for Phone (4b)

Nothing’s support page says that with its official charger, the Phone (4b) can reach a full charge in approximately 86 minutes. This is the manufacturer’s estimate and depends on charger protocol, temperature, and charging conditions; it is not a head-to-head test. Nothing also lists a protective case and pre-applied screen protector among the box contents. Nothing support.
