Motorola Razr 50 Ultra/razr+ (2024) review

Displays

The Motorola Razr 50 Ultra has a 6.9-inch foldable LTPO OLED screen of 1,080 x 2,640 pixels, which makes for 22:9 aspect ratio and 413ppi density. The screen supports up to 165Hz dynamic refresh rate, 10-bit color depth, HDR10+ and Dolby Vision streaming.

The cover screen has a similar panel - a 4-inch LTPO OLED display of 1,080 x 1,272 pixels or 417ppi. It also supports a dynamic 165Hz refresh rate, 10-bit color depth, HDR10+ and Dolby Vision streams.

We have completed our display measurements on both screens and they are quite good. The maximum manual brightness on both screens is around 540 nits, while the maximum automatic is around 1,270 nits.

The minimum brightness at point white for both displays is 2.8nits.

Refresh rate

There are two Refresh modes on the Motorola Razr 50 Ultra - High (up to 165Hz) and Standard (up to 60Hz). Both of these are dynamic, going from 1Hz up to 165Hz or up to 60Hz.

When the screen is idle, the refresh rate dials down to 1Hz. All sorts of videos are supported and the screen can be seen using 24Hz, 30Hz and 60Hz depending on the frame rate. Most of the UI is displayed in 90Hz and 120Hz. And most non-gaming apps are shown in 60Hz.

The only time the display offered the full 165Hz was in certain benchmarks or when this refresh rate was forced via the gaming sidebar.

The same behavior applies for the cover screen - 1Hz for idle, 24Hz-60Hz depending on the video content, 90Hz-120Hz for system UI.

Streaming and HDR

Both displays support HDR10, HDR10+ and Dolby Vision. Widevine L1 DRM is present on the Razr 50 Ultra. Unfortunately, Netflix serves 1080p SDR streams as it does not recognize any HDR capabilities. YouTube, on the other hand, does stream in 4K HDR.

Motorola Razr 50 Ultra battery life

Our new Active Use Score is an estimate of how long the battery will last if you use the device with a mix of all four test activities. You can adjust the calculation based on your usage pattern using the sliders below. You can read about our current battery life testing procedure here. For a comprehensive list of all tested devices so far, head this way.

The Motorola Razr 50 Ultra is powered by a 4,000mAh battery, a marginal increase in capacity over the previous model. The phone scored a very good Active Use Score of 12:05 hours. It can last about 22 hours on voice calls, over 10 hours on web browsing, over 15 hours on video streaming or about 8 hours of gaming.

Charging speed

The modest increase in battery capacity walks hand in hand with an increase in charging power rating to 45W, even though the Razr 50 Ultra ships with a 68W adapter. While we didn't get quite there in our testing (around 35W), the speed is an actual improvement.

We clocked an empty-to-full time of 47 minutes, with the battery indicator showing 76% at the half-hour mark. That makes the new model roughly twice as fast to charge as the previous one and faster than any other clamshell we've tested to date.

The Razr 50 Ultra supports wireless charging up to 15W, which should be perfectly good enough for overnight charging.

Speaker test

The Motorola Razr 50 Ultra has a stereo speaker setup - one unit is front-facing and also serves as an earpiece, while the other one is next to the USB-C port at the bottom of the phone.

Bottom speaker • Top speaker/earpiece

The earpiece is nicely loud, but focuses more on vocals and high frequencies, while the other speaker has richer sound. But the overall audio balance is great, and we have no complaints.

The speakers of the Razr 50 Ultra scored an Excellent mark on our loudness test, partly because of the well-presented high-frequency range. The vocals are solid, too, and there is enough bass. Overall, a well-deserved mark.

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.
