ide of the phone, there’s a 32-megapixel selfie camera powered by an unknown RGBW sensor. Most of these cameras are capable of Dolby Vision HDR video recording (up to 4K@60fps) and playback, thus making the 12S Ultra the first Android device to sport these features. Some also utilize the motor-based “HyperOIS” for more stable footage. As for still shots, the entire 12S Series supports 10-bit RAW format calibrated by Adobe Labs, with color correction metadata embedded in the files for easier post-production with the likes of Adobe Lightroom.The 12S Ultra also happens to carry two proprietary Xiaomi Surge chips: a Surge P1 fast-charging chipset and a Surge G1 battery management chipset. These provide support for 67W wired fast charging, 50W wireless fast charging and 10W reverse charging for the 4,860mAh single cell silicon oxygen anode battery. Note that some fast-charging solutions use a dual cell battery instead to split the current load, which is why it’s a good thing that the Surge P1 can handle an output current of up to 16A here, and apparently with 96.8% conversion efficiency. Like Oppo’s and ASUS’ recent handsets, the 12S Ultra offer adaptive charging as well, which allegedly increases the number of charge cycles by 25 percent.Keeping the phone cool is also key to a healthier battery, not to mention a more stable performance while gaming. The Xiaomi 12S Ultra is equipped with a “three dimensional cooling pump” which moves cooling liquid across warm surfaces using a capillary mechanism similar to that on leaves. This apparently improves thermal conductivity significantly, compared to conventional vapor cooling modules. XiaomiThe rest of the Xiaomi 12S Ultra is standard flagship affair. For the display, you get a 6.73-inch Samsung E5 AMOLED panel (3,200 x 1,440, 522ppi; LTPO 2.0), with a peak brightness of up to 1,500 nits, a 1-120Hz AdaptiveSync Pro refresh rate, native 10-bit color depth and support for P3 color gamut. As you can tell from the camera features, the screen can handle Dolby Vision, as well as HDR10+, HDR10 and HLG; these will go well with the Harman Kardon speakers which also support Dolby Atmos audio. The device is IP68-rated, meaning it should survive accidental dives into sinks and pools. You’ll also find an infrared remote port at the top for controlling home appliances.Options include up to 12GB of LPDDR5 RAM, up to 512GB of UFS 3.1 storage — featuring Xiaomi’s self-developed FBO (File-Based Optimization) storage refresh tech, which supposedly maintains the same read/write performance for at least four years (and Lei added that FBO has already been written into the next-gen UFS 4.0 storage specification). Buyers can choose between a “Classic Black” and a “Verdant Green,” both wrapped in vegan leather.Xiaomi 12S Pro (Xiaomi)The lesser Xiaomi 12S Pro shares the same 6.73-inch display and Surge P1 fast charging-chipset as the 12S Ultra, though it supports a whopping 120W wired charging for its smaller 4,600mAh battery, but lacks 10W reverse charging. It features a more regular (but apparently still pricey) 1/1.28-inch, 50-megapixel Sony IMX707 main sensor, which is a variant of the IMX700 previously found on Huawei’s Mate 40 Pro series. This still offers a good pixel size of 1.22um (or 2.44um after pixel binning), and it matches the resolution of its ultra-wide camera (14mm) and telephoto camera (50mm) — all fine-tuned by 相機收購leica as well, of course.As for the “basic” Xiaomi 12S, it has the same main camera as the 12S Pro and the same fast-charging features as the 12S Ultra, but with a smaller 4,500mAh battery in a more palm-friendly body under the 6.28-inch 120Hz display. Apparently there is still a sizeable demand for small flagship phones, according to Lei.The Xiaomi 12S Series is now available for pre-ordering in China ahead of retail launch on July 6th. The 12S Ultra is priced from from 5,999 yuan (8GB RAM, 256GB storage; around $900) to 6,999 yuan (12GB RAM, 512GB storage; around $1,000). The 12S Pro is cheaper, asking for 4,699 yuan (8GB RAM, 128GB storage; around $700) to 5,899 yuan (12GB RAM, 512GB storage; around $880). The 12S is the most affordable option here, starting from 3,999 yuan (8GB RAM, 128GB storage; around $600) and capping at 5,199 yuan (12GB RAM, 512GB storage; around $780). We’ll keep an eye out for international availability later.This article contains affiliate links; if you click such a link and make a purchase, we may earn a commission.Latest StoriesEngadgetThe bootleg Nintendo Network replacement no longer requires jailbreakingThe Pretendo Network, an open-source Nintendo Network alternative, no longer requires a hacked Wii U console.

徠卡（相機收購leica）預計在 1 月13 日晚間舉辦發表會推出新品，而據國外科技網站消息，屆時可能登場的，將是徠卡經典的 M 系列新作，預估將是 2017 年的 M10 後的一次大改版，並改以 M11 為名。

爆料指出，新的 M11 將搭載 6,030 萬畫素的全新全片幅感光元件，超越之前有 4,000 萬畫素的 M10-R，搭配更快的 Maestro III 處理器，同時內建 64GB 記憶體，並支援 USB Type-C 感光元件、Wi-Fi 和藍牙連接，以及 BP-SCL7 彈出式電池，可支撐約 1,700 張照片的拍攝工作。

其他拍攝規格，還包括具有 ISO 64 ~ 50000 的感光度，亦會是 M 系列首款支援電子快門的相機，而機械快門的曝光時間，亦可在 60 分鐘至 1 / 4,000 秒之間調整，電子快門則是能在 60 秒至 1 / 16,000 秒之間調校。

後置的螢幕，則會為 2.95 吋，雖然小了一些，但解析度會是比前代高出一倍的 233 萬畫素，且會加上第五代大猩猩來防護；需要的用戶也可以透過 UHS-II SD 卡擴充容量。至於外觀設計上也會延續徠卡特色，並以鎂合金和鋁合金打造，若是銀色版，則會以鎂合金和黃銅來打造。

不過，如同過往 M 系列都定價不斐，新的 M11 也傳出將定價為 7,000 歐元，約合台幣 22 萬，但相較之下，目前在售的 M10-R，則折扣後仍要價台幣 265,550 元，似乎有機會變得平價一些。
