– Xiaomi 17 Max features an 8,000 mAh SiC battery, among the largest in a Xiaomi phone.
– In a controlled video playback test, the 17 Max lasted 33.3 hours, outlasting two iPhone 17 Pro Max units (32 hours combined).
– Real-world endurance may vary due to screen brightness, codecs, network activity, thermals, and software optimization; independent reviews are needed to confirm.
Xiaomi just made a major battery-life statement with the upcoming 17 Max, expected to become official as soon as tomorrow. The 17’s larger 6.9-inch-screen brother packs a huge 8,000 mAh SiC battery, making it one of the largest cells ever used in a Xiaomi phone.
Battery Life Claim and Test Context
According to a video battery drain test shared on social media, the 17 Max managed to outlast not one, but two Apple iPhone 17 Pro Max units combined in a controlled video playback endurance test, where two iPhone 17 Pro Max achieved a combined runtime of 32 hours, while the Xiaomi 17 Max continued playing video for 33.3 hours.
Caveats About Test Conditions
That said, naturally, the results should be viewed for what they are. The comparison appears to have been conducted under controlled conditions and focused specifically on continuous video playback, which doesn’t necessarily reflect mixed real-world usage. Screen brightness, codec efficiency, network activity, thermal conditions, and software optimization can all dramatically affect battery endurance.
