Testing conducted by Apple in August 2026 using pre-production iPhone 18 Pro, iPhone 18 Pro Max and 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. Battery life varies by use, configuration, cellular network, signal strength and other factors; actual results may vary based on usage. Testing conducted by Apple in July 2026 using pre-production iPhone 18 Pro and iPhone 18 Pro Max 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 18 Pro and iPhone 18 Pro Max 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 USB‑C cable and USB PD 3.1 (or better) power adapters with Adjustable Voltage Supply (AVS). Fast‑charge testing conducted with drained iPhone units. 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.

Apple UK iPhone Duo technical specificationsiPhone 18 Pro
Manufacturer up-to claim, not measured mixed-use battery life. Testing conducted by Apple in August 2026 using pre-production iPhone 18 Pro, iPhone 18 Pro Max and 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. Battery life varies by use, configuration, cellular network, signal strength and other factors; actual results may vary based on usage. Testing conducted by Apple in July 2026 using pre-production iPhone 18 Pro and iPhone 18 Pro Max 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 18 Pro and iPhone 18 Pro Max 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 USB‑C cable and USB PD 3.1 (or better) power adapters with Adjustable Voltage Supply (AVS). Fast‑charge testing conducted with drained iPhone units. 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 up-to claim, not measured mixed-use battery life. Testing conducted by Apple in August 2026 using pre-production iPhone 18 Pro, iPhone 18 Pro Max and 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. Battery life varies by use, configuration, cellular network, signal strength and other factors; actual results may vary based on usage. Testing conducted by Apple in July 2026 using pre-production iPhone 18 Pro and iPhone 18 Pro Max 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 18 Pro and iPhone 18 Pro Max 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 USB‑C cable and USB PD 3.1 (or better) power adapters with Adjustable Voltage Supply (AVS). Fast‑charge testing conducted with drained iPhone units. 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.
