The iPhone XS and iPhone XS Max (Roman numeral "X" pronounced as "ten"[16]) are smartphones developed and marketed by Apple Inc. They are the twelfth-generation flagships of the iPhone, succeeding the iPhone X.[17] Apple CEO Tim Cook announced the devices alongside a lower-end model, the iPhone XR, on September 12, 2018, at the Steve Jobs Theater at Apple Park. Pre-orders began on September 14, 2018, and the devices went on sale on September 21.[18] At WWDC 2024, it was announced the iPhone XS would receive iOS 18. This makes it the oldest iPhone to support the latest version of iOS, and currently the oldest supported smartphone. The iPhone XS is the second model to receive at least 7 software updates from iOS 12 to iOS 18, following the iPhone 6s which received iOS 9 to iOS 15. [19]
Improvements include faster computing speeds, dual-SIM support, filming with stereo audio, and better water resistance.
The XS Max was the first plus-sized iPhone to have the reduced bezel form factor, as the iPhone X did not have a larger variant.
iPhone XS and XS Max are the final iPhone models to feature 3D Touch.
Design
The XS, which is visually near-identical to the iPhone X, has a better system-on-a-chip: the A12 Bionic chip built with a 7 nm process.[20] It has a 5.85 inch (149 mm) OLED display (marketed as 5.8 inch) with a resolution of 2436 × 1125 pixels (2.7 megapixels) at 458 ppi, dual 12-megapixel rear cameras, and one 7-megapixel front-facing camera.
The iPhone XS Max has the same hardware and cameras, but a larger 6.46 inch (164 mm) OLED display (marketed as 6.5 inch) with a resolution of 2688 × 1242 pixels (3.3 megapixels) at 458 ppi and a larger battery (3,174mAh).[21] The XS has a smaller battery than the X, dropping to 2,658 mAh from 2,716 mAh.[22] The XS' battery is a new single-cell L-shaped battery, while the iPhone XS Max battery remains two cells like the iPhone X.[23] Apple said that the iPhone XS lasts up to 30 minutes longer than iPhone X, while the iPhone XS Max lasts up to 1.5 hours longer than iPhone X.[24]

Apple said that the devices have faster Face ID technology than the iPhone X.[25] It was also announced in June 2019 at WWDC that Face ID on iPhone XS, iPhone XS Max, iPhone XR and iPhone X would be made up to 30% faster with iOS 13, which was released on September 19, 2019.[26]
The XS and XS Max are rated IP68 for dust and water resistance under IEC standard 60529, with Apple specifying a maximum depth of 2 meters and up to 30 minutes of submersion in water.[27] This is an improvement over the IP67 water resistance of the iPhone 8 and X.[28] Apple has performed tests in various liquids including chlorinated water, salt water, tea, wine, beer and juices.[29]
The XS and XS Max support dual SIMs through a nano-SIM and an eSIM. In mainland China, Hong Kong, and Macau, however, the XS Max comes with a dual nano-SIM tray (and no eSIM). The XS does not have a dual nano-SIM tray, so the eSIM functionality is enabled for use in Hong Kong and Macau, but not in mainland China.[30][31][32]
SoC
XS and XS Max use A12 Bionic SoC, which consists of 6-core CPU (2x Vortex + 4x Tempest), 4-core GPU, and 8-core Neural Engine.[33]
Software
The iPhone XS and XS Max originally shipped with iOS 12, and support iOS 13, iOS 14, iOS 15, iOS 16, iOS 17 and iOS 18. The iPhone XS and XS Max are the longest supported iPhones alongside the iPhone 6s, 6s Plus, and XR, all supporting 7 versions of iOS.
Wireless charging
The wireless charging coil material was switched to copper to reduce charging time and power loss.[34][35]
Rear camera upgrades
The iPhone XS, XS Max and XR are the first iPhones able to record stereo audio for videos.[36]
The iPhone XS received generally positive reviews from critics after release. iPhone XS and XS Max users initially had issues with LTE, Wi-Fi reception and Bluetooth connections. Some experts claimed that a faulty antenna was to blame,[46] and in response to many consumer complaints about iPhone XS/XS Max connectivity problems, Apple contacted users for help with their investigation.[47] To resolve some problems with the XS/XS Max, Apple pushed the iOS 12.0.1 update on October 8, 2018, which, along with addressing the Chargegate issue, fixed a connectivity issue where Bluetooth could become temporarily unavailable on the XS/XS Max.[48]
Chargegate
Users reported that the iPhone XS and XS Max would sometimes fail to charge by Lightning cable if it had been off for a while, and would only begin to charge if the screen was turned on.[49] This was caused by a software bug with Apple's "Disable USB accessories when locked" setting, a feature intended to prevent unknown devices from accessing a user's content. The press dubbed the issue "Chargegate".[50][51][52][53][54] This and a Bluetooth connectivity problem were fixed by iOS 12.0.1, released on October 8, 2018.[55]
Camera issues (Beautygate)
Customers also reported seeing unrealistic smoothness on their skin when taking a selfie with an automatic filter,[56] an effect associated with the XS and XS Max's new Smart HDR camera feature. This technology combines multiple photos of varying exposures to increase dynamic range on the iPhones' photos, but can also reduce facial imperfections and highlights in selfies. Some, who speculated this was the result of a hidden "beauty mode" (an actual feature in some smartphones), dubbed the issue "Beautygate". There was a general dispute in the community as to whether the camera actual "intended" to "perfect" faces or if they just appeared that way as result of a better-quality camera.[57]
Apple said that these results were due to the Smart HDR algorithm incorrectly selecting the blurrier long exposure as its base frame instead of the sharpest short exposure. The issue was resolved with the release of iOS 12.1 on October 30, 2018.[58][59]
The iPhone XS' camera was criticized for not featuring a night mode.[60][61][62] iOS 13 did not include night mode which was kept exclusive to the then-new iPhone 11.[63] However, third-party apps brought similar Night Mode to older iPhones.[64]

Apple told me that the forthcoming iOS 12.1 update, currently in public beta, will address the issue of the front camera appearing to smooth out skin by picking a sharper base frame for Smart HDR, but I wasn't able to test it yet.
