Xiaomi 17 Ultra

HPE (1/1.4", 200MP) periscope and new lens group

Engineering prototype with a minimum aperture of F3.0± and a maximum aperture of F2.3± within the variable focal length range

Let's analyze based on the available information

The Xiaomi 15 Ultra uses a 1/1.4" HP9 sensor at 100 mm (4.3×) with f/2.6. Since the Xiaomi 17 Ultra will use the same-sized 1/1.4" HPE sensor, we can use the 15 Ultra’s f/2.6 at 100mm as a reference—aperture scales proportionally with focal length

The ratio between f/3.0 and f/2.6 is 3 ÷ 2.6 ≈ 1.15
New focal length: 100 mm × 1.15 = 115 mm
Xiaomi 15 Ultra: f/2.6 @ 100 mm
Xiaomi 17 Ultra (long end): f/3.0 at 115 mm

The ratio between f/3.0 and f/2.3 is 3 ÷ 2.3 ≈ 1.30
Short end focal length: 115 mm ÷ 1.30 ≈ 88 mm (DCS gave approximate f-numbers, so round to 85 mm)

Thus, the Xiaomi 17 Ultra periscope should span roughly 85mm (3.7x) with f/2.3 to 115mm (5x) with f/3.0 using continuous optical zoom

Samsung is dropping the 3x telephoto from the S27 Ultra

It's mainly because Apple switched the iPhone 17 Pro series to 4x—now that 4x sits right in the middle, keeping separate 3x and 5x modules doesn't make sense anymore

S26 Ultra will offer 24MP mode in both auto and portrait

S25 Ultra only gets 24MP in Expert RAW, sticking to 12MP in auto

With the leaked faster aperture on S26 Ultra, 24MP in auto mode becomes possible without shutter speed issues—unlike S25 Ultra, which still struggles even at 12MP

S25 Ultra vs Find X9 Pro comparison at 10x zoom

S25 Ultra has a longer focal length starting from 5x, from which it crops to 10x, but Find X9 Pro has a bigger sensor at 3x which compensates for the longer distance

S25 Ultra at 10x - 1/5.04" with f/6.8
Find X9 Pro at 10x - 1/5.2" with f/7.0

The crucial role here is played by the difference in resolution, as Find X9 Pro outputs 26MP samples and S25 Ultra 12MP

Exclusive Foresight:
OPPO is doing next-generation pre-research on two 200 MP periscopes

— One 1/1.3"± (OV52A or SmartSens SC880XS)
— The other 1/1.12"± (IMX09E)

These are the telephoto solutions for two different flagships

The IMX09E (1/1.12") is likely for the Find X10 Ultra, while the 1/1.3" option may target the Find X10 Pro

No continuous zoom yet—currently fixed focal length

The battery is the dual-cell single-port solution, this glacier battery also uses anew generation of spherical silicon-carbon negative electrode material. The silicon content has been increased to 15%, and the capacity has reached an equivalent of 7300mAh (27.6Wh), which is 1300mAh (4.68Wh) higher than the previous generation. The manufacturer is still Dongguan Xinnengde — ATL battery cell. The energy density is calculated through the packaging size to be around 823Wh/L, which is slightly higher than the previous generation's 790Wh/L

The X-axis linear motor uses the same AAC ESA0816 specification (third-generation technology) as its big brother Find X9 Pro. The overall performance is approximately equal to the larger ESA1016 (third-generation technology), which is slightly better than ESA7514A (third-generation technology). However, it is still a little behind the previous generation CSA+0916Turbo (CSA0916B fourth-generation technology). Refer to the diagram below for the rankings

The whole machine is equipped with three microphones, one less rear microphone than the previous generation. The placement logic of the three microphones is slightly different from the conventional solution of placing one on the top and one on the bottom. OnePlus 15 adopts the arrangement of one on the top and two on the bottom. There is no sound receiving hole on the back of the fuselage(rear side)

The screen is still from BOE, supports LTPO, and the luminous material is upgraded to X3. The resolution is reduced from 2K to 1.5K, but the refresh rate is increased to 165Hz. Before OnePlus the ultra-high refresh rate screen can only achieve a maximum resolution of 1080P. The operation of OnePlus 15 is to raise the upper limit of the industry. And this 165Hz is not for only gaming scenes. WeChat, Weibo, Xiaohongshu, QQ, etc. have all been adapted, and the refresh rate will be relatively smoother. The default supports medium and high brightness single-scan DC dimming + low brightness high-frequency PWM dimming
