Realme 15 Pro review

Display

The Realme 15 Pro features a 6.8-inch OLED display of 1,220 x 2,800 pixels (453ppi). It has 10-bit color depth, supports up to 144Hz refresh rate, 4608Hz PWM dimming, and HDR10+ content.

The screen has Gorilla Glass 7i protection and it's quad-curved it more aggressive curving than what we've seen lately.

The official brightness numbers are quite impressive - 1,800 nits of high maximum brightness and up to 6,500 nits of peak brightness.

Our measurements confirm the official maximum - we captured 1,862 nits of maximum automatic brightness. The manual one without the Extra Brightness boost was 586 nits and with the Extra boost - 994 nits. These numbers present a solid performance!

The minimum brightness was just 1.9 nits. A useful feature is the 'Lowest allowed brightness' slider, which lets you set a minimum brightness value below which the display will not go in Auto brightness mode. This prevents the screen from getting overly dark in dark environments, something that is otherwise quite common.

The display has a rated maximum frame rate of 144Hz. However, if you thought you could just set the display to 144Hz and have it available in all apps, you thought wrong.

As it stands, the phone will only refresh at up to 120Hz in the vast majority of apps. Only a handful of system apps can be manually set to 144Hz through the app-specific refresh rate settings. This includes gems such as the Calculator, Compass, and the Recorder, which most definitely deserve to get the full 144Hz refresh rate treatment, while things like browsers, games, and social media apps are limited to 120Hz. In fact, the system will set certain apps to 90Hz or even 60Hz, and you then need to manually raise them up to 120Hz.

This is unfortunate, as the 144Hz number is reduced to being purely a marketing fluff, as you can never realistically achieve that frame rate in most of your everyday apps.

Rant over, moving on to the actual Refresh rate options. There is High, Standard and Auto models. Both High and Auto use 60Hz when idling. The Auto mode uses 90Hz in most apps, while High goes with 120Hz where available and where allowed from the app-specific menu.

Don't get this wrong, the picture is as smoot has on any 120Hz refresh rate, but we expected to see 144Hz used at least for the system UI.

The screen is HDR10+ certified. HDR10 streaming is available on YouTube and Netflix. It also works in the Gallery if you enable the Pro XDR toggle.

Battery life

The Realme 15 Pro has a massive 7000mAh battery, something you'd never guess by the impressive 7.69mm thickness of the body and otherwise perfectly normal proportions. Realme claims it is the thinnest 7000mAh battery phone in this segment.

The battery in question is a single-cell Li-ion unit with a graphite anode, although a dual-cell silicon anode variant will also be available in regions outside of China and India.

The phone posted an Active Use Score of 17:04 hours, making it the 10th best phone in our all-time battery life chart. The phone lasted over 40 hours on calls, nearly 18 hours of web browsing, almost 22 hours of video streaming, and 8:42h of gaming - impressive times across the board!

Charging speed

The Realme 15 Pro supports the company's proprietary 80W SUPERVOOC charging.

Using the bundled charger in the box, the phone was able to charge the battery completely in just under an hour, with about two-thirds of it achieved in just 30 minutes. This is an absolutely incredible rate of charging for a battery that you'd previously expect to find inside a tablet.

There are various battery preservation options. Smart Charging is one of those, where the phone learns your habits and refills the last 20% of the battery close to, say, your wakeup time. Then there is Charging Limit - the battery is kept at 80% charge for lower cycle count and prolonged lifespan.

There are also a couple of power-saving battery modes, as well as GT mode for maximum performance.

The phone only offers wired charging with no wireless charging option. However, you do get bypass charging (within the Game Booster), so you can run the phone directly off the charger while playing a game instead of charging the battery, which reduces the heat buildup.

Speakers - quality and loudness

The Realme 15 Pro has a set of stereo speakers. The earpiece is focused on the high-frequency range and vocals, and it is noticeably quieter. Still, the audio balance is quite alright.

The speakers get reasonably loud and scored a Good mark on our loudness test. The quality isn't great and somewhat tinny, but it can be rated as Good, too.

The phone only supports spatial audio processing using Oppo's OReality, and there's no support for Dolby Atmos.

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.
