POCO F9 Ultra Compared to Xiaomi 17T Pro: Key Differences

Two smartphones from the same company released months apart sit roughly €200 apart on paper, forcing buyers to weigh whether the POCO F9 Ultra’s larger silicon-carbon battery and Bose-tuned speakers justify paying more over the Xiaomi 17T Pro.

Xiaomi launched the Xiaomi 17T Pro on May 28, 2026, and its performance brand POCO followed with the POCO F9 Ultra on September 1, 2026. Both devices ran into the same review verdict: great phones at launch prices that are hard to justify, according to Memeburn. POCO operates as Xiaomi’s sub-brand focusing on speed and battery, whereas the T series serves as a cheaper, Leica-branded alternative to Xiaomi’s main flagships.

Battery Tests and Hardware Differences Between the Xiaomi and POCO Models

Both smartphones utilize silicon-carbon batteries, which integrate silicon into the anode to hold more energy without increasing physical size. However, the POCO F9 Ultra features an 8,050mAh capacity, which is 1,050mAh or 15% larger than the 7,000mAh capacity inside the Xiaomi 17T Pro.

Independent lab testing reflects that extra capacity. The POCO F9 Ultra achieved an Active Use Score of 24 hours 35 minutes, outlasting the Xiaomi 17T Pro score of 21 hours 41 minutes by about 13%. The official EU energy label endurance ratings show a similar margin, with the POCO ahead by about 14% at 80 hours 44 minutes compared to the Xiaomi’s 70 hours 55 minutes.

Charging specifications are largely a draw. Both devices support 100W wired charging and 50W wireless charging. In lab testing, the Xiaomi reached a full charge in 44 minutes while the POCO took 54 minutes to fill its larger battery, resulting in comparable speeds of roughly 159mAh per minute for Xiaomi and 149mAh per minute for POCO. For power sharing, the POCO supports 27W wired and 22.5W wireless reverse charging, whereas the Xiaomi offers 22.5W wired reverse charging.

Audio Quality, Display Tech, and Verdict for Buyers

Beyond battery life, the POCO F9 Ultra incorporates a 2.1 speaker setup tuned by Bose, featuring two stereo speakers alongside a dedicated woofer on the back for bass. Independent testing described the POCO sound as excellent, while rating the Xiaomi speakers as disappointing with little bass and harsh highs at high volume, even though the Xiaomi measured slightly louder.

POCO also includes an ultrasonic fingerprint reader that maps fingers using sound waves, performing better with wet or greasy fingers, and adds a separate VisionBoost D8 chip for frame interpolation in supported games. Meanwhile, Memeburn notes that Xiaomi wins on camera hardware, video capabilities, software support, and comfort.

Ultimately, discounts make the Xiaomi 17T Pro the better purchase for most buyers because its 512GB model has fallen below the price of the base POCO. The POCO F9 Ultra remains recommended for power users when it nears its early-bird price.
