Nothing UK Phone (4a): selected configuration and complete specificationsiPhone Duo
Testing conducted by Apple in August 2026 using pre-production iPhone Duo units and software, subscribed to LTE and 5G networks, using a representative usage profile. Profile is based on the median usage values across iPhone users and reflects a combination of passive and active use of a variety of applications, including but not limited to messaging, photos, music, social media, video streaming, games, web browsing and navigation. iPhone Duo typical use based on equal usage between inner and outer displays. Battery life varies by use, configuration, mobile network, signal strength and other factors; actual results may vary based on usage. Testing conducted by Apple in July 2026 using pre‑production iPhone Duo units and software, subscribed to LTE and 5G networks. Video playback consisted of a repeated 2‑hour 23‑minute HDR movie purchased from the iTunes Store. Video playback (streamed) consisted of a repeated 3‑hour 1‑minute HDR movie purchased from the iTunes Store. All settings were default except: Bluetooth was paired with headphones; Wi‑Fi was associated with a network; the Wi‑Fi feature Ask to Join Networks, Auto‑Brightness and True Tone were turned off. Testing conducted by Apple in July 2026 using pre‑production iPhone Duo units and software, and either USB‑C Charge Cable or Apple MagSafe Chargers (1‑metre Model A3502 and 2‑metre Model A3503), both with Apple 40W Dynamic Power Adapter with 60W Max (Model A3351). Wired fast charge supported with 60W-capable (or higher) USB‑C cable and USB PD power adapters. Fast-charge testing conducted with drained iPhone Duo units in open configuration. Times measured from the appearance of the Apple logo as the unit started up. Charge time varies with adapter, settings, usage and environmental factors; actual results will vary.

Manufacturer battery and charging claimsDiffers
5080 mAh; 50 W wired, 7.5 W reverse wiredFull published battery specification: 5080 mAh (UK; 5400 mAh in India only); 50 W wired charging; 7.5 W reverse wired charging; Charging protocols: PPS, PD3.0, PD2.0, QC3.0, QC2.0, DCP, SDP, CDP, UFCS.
Typical use Up to 24 hours Video playback Up to 44 hours when using the outer display Up to 31 hours when using the inner display Video playback (streamed) Up to 37 hours when using the outer display Up to 26 hours when using the inner display Dual built-in rechargeable lithium-ion batteries Fast-charge capable: Up to 50% charge in around 20 minutes with 60W-capable adapter or higher (available separately) paired with USB-C charging cable Up to 50% charge in around 30 minutes with 35W adapter or higher paired with MagSafe Charger (both available separately)Testing conducted by Apple in August 2026 using pre-production iPhone Duo units and software, subscribed to LTE and 5G networks, using a representative usage profile. Profile is based on the median usage values across iPhone users and reflects a combination of passive and active use of a variety of applications, including but not limited to messaging, photos, music, social media, video streaming, games, web browsing and navigation. iPhone Duo typical use based on equal usage between inner and outer displays. Battery life varies by use, configuration, mobile network, signal strength and other factors; actual results may vary based on usage. Testing conducted by Apple in July 2026 using pre‑production iPhone Duo units and software, subscribed to LTE and 5G networks. Video playback consisted of a repeated 2‑hour 23‑minute HDR movie purchased from the iTunes Store. Video playback (streamed) consisted of a repeated 3‑hour 1‑minute HDR movie purchased from the iTunes Store. All settings were default except: Bluetooth was paired with headphones; Wi‑Fi was associated with a network; the Wi‑Fi feature Ask to Join Networks, Auto‑Brightness and True Tone were turned off. Testing conducted by Apple in July 2026 using pre‑production iPhone Duo units and software, and either USB‑C Charge Cable or Apple MagSafe Chargers (1‑metre Model A3502 and 2‑metre Model A3503), both with Apple 40W Dynamic Power Adapter with 60W Max (Model A3351). Wired fast charge supported with 60W-capable (or higher) USB‑C cable and USB PD power adapters. Fast-charge testing conducted with drained iPhone Duo units in open configuration. Times measured from the appearance of the Apple logo as the unit started up. Charge time varies with adapter, settings, usage and environmental factors; actual results will vary.
