Xiaomi 17 review

6.3-inch LTPO OLED display

The Xiaomi 17 features a similar to the previous Xiaomi 15, but upgraded, 6.3-inch LTPO OLED display. The panel caps at a 120Hz refresh rate, and since it's LTPO, it can granularly adjust it between 1 and 120Hz. Resolution is 1220 x 2656px and has 12-bit color depth.

Other notable features include high-frequency PWM at 2160Hz for users with sensitive eyes and support for all the popular HDR standards - HDR10+, HDR Vivid and Dolby Vision.

The Xiaomi 17's display peaked at a little above 1,000 nits on a 75% white patch in auto mode and reached more than 3,400 nits with a 10% patch. Both metrics suggest excellent outdoor legibility on a bright sunny day as well as a great HDR experience.

In manual mode, the screen is capped at 627 nits, while the minimum brightness goes all the way down to 1.3 nits.

Refresh rate

Since it's in LTPO display, it offers granular refresh rate control between 1 and 120Hz. The Default refresh rate mode offers just that, while the Custom option allows you to limit the refresh rate to 60Hz or force 120Hz in some apps.

Interestingly enough, there's an Adaptive refresh rate Pro toggle in the Display menu. It switches from DC dimming to high-frequency PWM and unlocks the granular refresh rate adjustment. Otherwise, you will be using the display in two modes - 60Hz and 120Hz.

To our surprise, the Xiaomi 17 Ultra had no problem going down to 1Hz even without that option.

Anyway, with the toggle turned on, the Xiaomi 17 adapts perfectly to all apps we tested. It brings down the refresh rate to 1Hz when the screen is idle, and boosts up to 120Hz in pretty much all other scenarios, except video playback.

In video streaming apps, such as YouTube, the display adapts to the particular video frame rate. For instance, playing a 24fps or 30fps video will match the refresh rate at 24Hz or 30Hz, respectively.

Battery life

The Xiaomi 17 has a monster 6,330 mAh battery, which is an impressive feat considering the size. The Chinese version of the model has 7,000 mAh, but even the reduced capacity here produces great battery life when coupled with a power-efficient screen.

The 17 outperformed its bigger and more expensive siblings, the Xiaomi 17 Ultra and the Xiaomi 17 Pro Max. The vanilla 17 achieved an Active Use Score of 21:15h with exceptional screen-on runtimes.

Charging speed

The Xiaomi 17 supports 100W fast wired charging if you plug it into a proprietary 100W Xiaomi HyperCharge charger. The device also supports 50W wireless charging, again, if you use one of Xiaomi's compatible wireless charging stands. You can also charge other devices using 22.5W reverse wireless and wired charging features.

With a compatible Xiaomi charger, the phone can get you from 1 to 100% in just 46 minutes, while a 30-minute charging session restores more than 70% of the battery.

Even though it's slower than the previous generation, it holds up pretty well against the current competition and even outpaces its rivals with ease.

There are some battery health-oriented features in place. You can limit the charging capacity to 80% or apply smart charging to avoid overcharging as the system learns your charging habits and finishes charging the battery only when needed. You can, of course, disable fast charging altogether.

Speakers

Unsurprisingly, the Xiaomi 17 features a set of hybrid stereo speakers, with the top one being slightly quieter than the bottom one. The top speaker is also used as an earpiece during voice calls.

Back to the speakers, they earned a "Good" -26.6 LUFS loudness score, which is exactly what the Xiaomi 17 Ultra scored. It's also a notch quieter than last year's model.

On the other hand, Xiaomi has improved the sound quality over the previous generation. The bass is now more prominent and makes music tracks sound "fuller". It's no match for the 17 Ultra's bass, but it gets pretty close. Our only complaint is that the bass overpowers the vocals.

When compared to its competitors, the Xiaomi 17 stands out with one of the best speakers in its class. Subjectively speaking, we liked the Galaxy S25's speakers a little better, but the vivo X300 and the Pixel 10 Pro were no match for the Xiaomi.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
