iphone 11 pro
The iPhone 11 Pro and iPhone 11 Pro Max are smartphones designed, developed and marketed by Apple Inc. Serving as Apple's flagship models of the 13th generation of iPhones, they succeeded the iPhone XS and iPhone XS Max, respectively, upon their release. Apple CEO Tim Cook unveiled the devices alongside the standard model, the iPhone 11, on September 10, 2019 at the Steve Jobs Theater at Apple Park. Pre-orders began on September 13, 2019, and the phones went on sale on September 20. They were discontinued on October 13, 2020, following the announcement of the iPhone 12 and iPhone 12 Pro.
Notable improvements over the previous devices include the triple-lens rear camera system and the A13 Bionic chip. The 11 Pro and 11 Pro Max are Apple's first iPhones to feature a "pro" designation, previously used only for larger Apple devices, such as the iPad Pro and MacBook Pro. They are also the first generation of iPhones which include a Lightning to USB-C cable and that allows connection to the charger and to current Mac computers, in the box.

History
Details regarding the smartphones were leaked widely starting several months before the official release, with complete specifications, renderings, and real-life images of the phone being publicized. Substantial advancements in the camera and the continuation of the 'notch' design featured since the iPhone X were correctly predicted in leaks. Some leaks, however, were inaccurate; the inclusion of bilateral charging was widely anticipated and publicized, but was not part of the phone's design. Official release event invites sent out to press featured layered colored glass elements organized to form the Apple logo, which some reviewers drew similarities to Apple's original logo, suggesting new colors for the phone, and to a patent Apple filed for a new camera design earlier.The iPhone 11 and 11 Pro were unveiled in a press event at the Steve Jobs Theater in Cupertino, California on September 10, 2019; the first Apple event live streamed on YouTube.  The event featured various other products and services other than the iPhone, including a new Apple Watch, a new iPad, Apple TV+, and Apple Arcade. Pre-orders began on September 13, with the iPhone 11 Pro starting from a base price of $999, and the larger screen Pro Max starting from $1,099. The phones were released on September 20.On October 13, 2020, following the announcement of the iPhone 12 Pro and 12 Pro Max, the iPhone 11 Pro and 11 Pro Max were removed from sale on Apple's official website.In February 2021, Apple started selling refurbished iPhone 11 Pro models starting at $849.

Design
The iPhone 11 Pro and 11 Pro Max is available in Gold, Silver, Space Gray, and Midnight Green, a new color previously not available on iPhones. Similar to the iPhone XS and XS Max respectively, there is a display cutout at the front that includes the 12 MP TrueDepth camera system and speaker. There is also a new rear camera design with three lenses and a flash in a larger, square-shaped bump, which is the most visible difference compared to the iPhone XS. The Apple logo is now centered on the back of the device with no text, and the glass has a frosted matte finish, unlike the glossy finish found on other previous flagship iPhones.

However, Apple limits the full range of zoom (0.5× -6×) while shooting in 4K @ 60fps to either 0.5× – 1.5×, 1×, to 2× depending which lens is selected upon recording. All other resolutions/frame rates support the full zoom set. The phone also features an audio zoom feature which focuses audio on the area that is being zoomed in on. All of the cameras support video although only the wide and telephoto come with optical image stabilization.

The front camera also supports stabilized 4K video recording up to 60fps. Apple has added slow-motion video recording to the front camera in 1080p at up to 120 fps, a feature which Apple refers to as "slofies".

Reception
Upon release, the iPhone 11 Pro received generally positive reviews, with critics highlighting the improvements to the camera, display, and battery, although it was criticized for its similar design to the iPhone XS and the large camera bump, as well as the lack of rumored features such as bilateral wireless charging and USB-C. TechRadar critics praised the improved camera array, calling it "clearly the big upgrade", and also praised the faster A13 Bionic processor, and the display, while criticizing the design similarities compared to the iPhone XS including the display cut-out for the sensor housing, commonly referred to as "the notch," and also criticizing the cost. Pocket Lint also positively described the camera, the processor, display, and battery, camera design, and lack of bilateral wireless charging. The Verge and T3 positively described the general aspects of the phone, while stating that the 'pro' label may not be fully justified as the phone only helps Apple keep up with the competitors, not surpass them.
The device received an overall score of 117 from DXOMARK, ranking it as the second-best smartphone camera on the site tied with the Samsung Galaxy Note 10+. An 11-point improvement over its predecessor, it had a photo score of 124 and a video score of 102.

Environmental data
Carbon footprint
The iPhone 11 Pro has a carbon footprint of 80 kilograms (180 lb) CO2e emissions, which is 10 kilograms (22 lb) more than the preceding iPhone XS and 25 kilograms (55 lb) more than the iPhone 3G in 2008. 83% of the emissions are caused by the production of the device and primary resources while remaining emissions are caused by transportation and first use.

Repairability
The iPhone 11 Pro and Pro Max continue the strategy of discouraging customers to seek third party repairs while rendering repairs with Apple more costly: repair with non-genuine Apple parts such as batteries or displays can trigger warning messages on the phone instigating the customer to visit a certified technician to replace the respective parts with genuine ones. While the website clearly states that the phone will function properly despite the warning, this information is not passed in the context of the warning. Even if batteries are properly functioning and at full capacity the customers are prompted by a message on the phone to replace the battery. At the same time battery replacement with original spare parts saw an increase in pricing: after initially discounting battery replacements to $29 following the Batterygate scandal, battery replacement prices for all flagship iPhone models was reverted to US$69.00.
