Waste

  • No established final assembly sites generate waste sent to landfill as part of Apple’s Zero Waste Programme25

Smarter chemistry26

  • All the materials used in Apple products, accessories and packaging are covered by the requirements of our Regulated Substances Specification, which was one of the first in industry to restrict the use of key substances of concern. See the latest En­viron­men­tal Progress Report to understand Apple’s recent efforts in phasing out these chemistries.

*To identify your iPhone model number, see support.apple.com/en-gb/108044. For details on 5G and LTE support, contact your network provider and see apple.com/uk/iphone/cellular. Mobile data technology support is based on iPhone model number and configuration for GSM networks.

  1. Available space is less and varies due to many factors. A standard configuration uses approximately 12GB to 24GB of space, including iOS 27 with its latest features and Apple apps that can be deleted. Apple Intelligence on‑device models use approximately 7GB of space and can be deleted if Apple Intelligence is turned off. Turning on Apple Intelligence will download the models again. Apple apps that can be deleted use about 4.5GB of space, and you can re‑download them from the App Store. Storage capacity subject to change based on software version, settings and iPhone model.

  2. Size and weight vary by configuration and manufacturing process.

  3. Coming later this year.

  4. iPhone Duo is splash, water and dust resistant and was tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum depth of 6 metres up to 30 minutes). Splash, water and dust resistance are not permanent conditions. Resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.

  5. Apple Intelligence is available with Siri and device language set to Chinese (Simplified), Chinese (Traditional), Danish, Dutch, English, French, German, Italian, Japanese, Korean, Norwegian, Portuguese, Spanish, Swedish, Turkish or Vietnamese. Some features may not be available in all regions or languages. Some devices may not be available in all regions. Siri AI is available in beta in iOS 27 and requires an Apple Intelligence–enabled device set to a supported language. Available in English to start. Siri AI will not be initially available in the EU on iOS. Certain Apple Intelligence features that rely on server-side models are subject to daily usage limits, including but not limited to Siri AI, Intelligent Photo Editing Tools, Image Playground, and AFM 3 Cloud models in Shortcuts. Daily limits may vary by feature, request complexity, system demand, system policies and other factors. Expanded access to such features will be available for a fee in the future. Use of these features is subject to the Apple Intelligence Terms and Conditions. Learn more at apple.com/uk/apple-intelligence.

  6. 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.

  7. 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.

  8. 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.

  9. Service is included free for two years with the activation of any iPhone 14 or later model. Connection and response times vary based on location, site conditions and other factors. See support.apple.com/en-gb/105097 for more information.

  10. iPhone Duo, iPhone 18 Pro, iPhone 17e, iPhone 17 and iPhone Air can detect a serious car crash and call for help. Requires a mobile data connection, satellite connectivity or Wi‑Fi calling.

  11. Data plan required. 5G, Gigabit LTE, VoLTE and Wi‑Fi calling are available in selected markets and through selected network providers. Speeds are based on theoretical throughput and vary based on site conditions and network. For details on 5G and LTE support, contact your provider and see apple.com/uk/iphone/cellular.

  12. Wi‑Fi 7 available in countries and regions where supported.

  13. Ultra Wideband availability varies by region.

  14. USB 3 cable with 10Gb/s speed required.

  20. Wireless broadband recommended; fees may apply.

  21. Product recycled or renewable content is the mass of certified recycled material relative to the overall mass of the device, not including packaging or in-box accessories. Recycled and renewable plastic content calculation includes mass balance allocation.

  22. Breakdown of US retail packaging by weight. Adhesives, inks and coatings are excluded from our calculations of plastic content and packaging weight. Fibre sourcing requirements are defined in Apple’s Responsible Fibre Specification. We consider wood fibres to include bamboo.

  23. We estimate the percentage of electricity‑related emissions in our manufacturing that is sourced from low‑carbon electricity by attributing to our carbon model low‑carbon energy procured by our suppliers in the prior fiscal year, based on the supplier manufacturing allocations at time of product launch. Included in this number is only low‑carbon electricity that Apple or its suppliers have procured as part of Apple’s Supplier Clean Energy Programme.

  24. Efficiency performance is based on the US Department of Energy Federal Energy Conservation Standards for Battery Chargers.

  25. All established final assembly supplier sites — those that have been Apple suppliers for more than one year — for iPhone Duo are third-party verified as Zero Waste by UL LLC (UL 2799 Standard). UL requires at least 90% diversion through methods other than waste to energy to achieve Zero Waste to Landfill (Silver 90–94%, Gold 95–99% and Platinum 100%) designations.

  26. Apple’s Regulated Substances Specification describes Apple’s restrictions on the use of certain chemical substances in materials in Apple products, accessories, manufacturing processes and packaging used for shipping products to Apple’s end customers. Restrictions are derived from international laws or directives, regulatory agencies, eco‑label requirements, environmental standards and Apple policies. Every Apple product is free of PVC and phthalates except for AC power leads in India, Thailand (for two‑pin AC power leads) and South Korea, where we continue to seek government approval for our PVC and phthalates replacement. Apple products comply with the European Union Directive 2011/65/EU and its amendments, including exemptions for the use of lead such as high‑temperature solder. Apple is working to phase out the use of these exempted substances for new products where technically possible.

Features are subject to change. Some features, applications and services may not be available in all regions or all languages and may require specific hardware and software. For more information, see Feature Availability.
