The online store of Apple is ahead of the iPhone XS, the iPhone XR and the Apple Watch Series 4 preorders

Apple ended Thursday at its online store for maintenance, customers preparing to visit the site in a few hours to pre-order the latest hardware iPhone and Apple Watch.

The online storefront has collapsed around 5:50 pm Pacific as Apple prepares for an expected rush of the iPhone XS, iPhone XS Max and Apple Watch Series 4 orders.

Customers attempting to visit the page will encounter a new landing page containing the text "Be Right Back" under an animated Apple logo. Apple is expected to postpone the site online at 12:01 PM Pacific Time, when pre-orders for the latest iPhone and Apple Watch devices will be launched.

Introduced during a special event on Wednesday, the iPhone XS and XS Max are the successors of the famous flagship product of the iPhone X from last year. Powered by the new A12 Bionic processor, the handsets feature full OLED displays (5.8 inches for the XS and 6.5 inches for the XS Max), advanced dual-camera bays, increased durability, and more. water and much more. TrueDepth, the specialized depth detection system underlying Face ID, is taken from the iPhone X in 2018, thanks to modified algorithms and a faster processor.

The A12 Bionic features two high-performance cores, 15% faster than last year, and four efficient cores using up to 50% less energy than the predecessor of the system-on-a-chip. The Apple graphics processor, designed in-house, gets four cores, compared with three in the A11, to improve performance by 50%.

The most notable, however, is the neural engine of Apple, an 8-core unit capable of performing 5,000 billion operations per second. Specialized software and hardware features, including the iPhone's camera system, which uses the neural engine to enhance portrait mode and intelligent HDR photography, make use of this computing power. CoreML also gets a good return thanks to its links with the new machine learning module.

Both iPhone XS and XS Max include two 12 megapixel rear cameras with optical stabilization with wider and deeper pixels for better low-light pictures and enhanced TrueTone flash. A new sensor is behind the wide-angle shooter, with an f / 1.8 lens, while the camera has a 2X optical zoom and f / 2.8 lens. Like last year, the handsets are capable of capturing 4K videos at 60 frames per second.

Other enhancements include a new glass rear frame structure that supports Qi wireless charging, True Tone display technology, redesigned stereo speakers, and enhancements for augmented reality applications.

The iPhone XS is selling $ 999 for 64GB of storage, with a 256GB model priced at $ 1149, and the new 512GB option available for $ 1349. The iPhone XS Max will sell for $ 1099 with 64GB of storage, $ 1,249 for 256GB and $ 1449 for 512GB.

Apple introduced its first major Apple Watch overhaul with Apple Watch Series 4, compressing OLED displays, dramatically improving heart rate monitoring capabilities, a new SoC S4, and internal sensors redesigned in a thinner chassis.

Starting with the screens, Apple says that almost edge-to-edge displays are 30% larger than previous Apple Watch models. Despite its larger size, Apple has managed to maintain battery life in line with last year's models by integrating LTPO technology. Taking advantage of the additional real estate benefits are the first-party applications and faces with redesigned user interfaces.

The Apple Watch heart rate sensor has been completely reworked to accommodate a new electric sensor capable of taking electronic ballasts, useful for identifying life-threatening problems such as atrial fibrillation. The electrodes frame the optical heart rate sensor with a redesigned digital crown that receives the electrical signals sent to the user's body, from the wrist to the fingertip. Apple was able to obtain FDA clearance for ECG detection and aFib detection.

In addition to playing a vital role in ECG readings, the new Digital Crown now supports the return of haptic information. The Apple Watch speakers have been redesigned to be 50% more powerful, while their microphone has been moved to improve audio quality.

Internal sensors have also been upgraded, providing greater accuracy. Apple takes advantage of new features by integrating unique features such as fall detection.

Instead of different models of the Apple Watch using different back composites depending on the model, all models in the 4 Series will feature ceramic backs, a material that offers better cell transmission and advanced cardiac monitoring . .

Apple Watch Series 4 will be available in sizes 40mm and 44mm. The usual shades of silver, gold and dark gray aluminum are back, while the stainless steel versions will be sold in silver, Space Black and a new gold color. Nike + models with special faces and watch bands are also available.

Prices start at $ 399 for 40mm aluminum versions with GPS, while 44mm models cost $ 429. Aluminum models with cellular connectivity sell for $ 499 for 40mm and $ 529 for 44mm. All stainless steel models incorporate GPS + Cellular capabilities and start at $ 699 for 40mm sizes and increase to $ 749 for 44mm.
