Realme GT 7 Review: This Smartphone Breaks All Battery Life Rules!

June 14, 2025

Test du Realme GT 7 : le smartphone qui casse les codes de l’autonomie
The Realme GT 7 packs a 7000 mAh battery within the slim profile of an iPhone. With this latest model, the Chinese manufacturer aims to dominate the smartphone market in terms of battery life.

Less than a year after the launch of the GT 6, which had already impressed us, Realme is back with a new series. Positioned between mid-range and high-end, the GT 7 competes directly with the likes of the iPhone 16.

The price might seem steep, but the specifications justify it, although it lacks an optical zoom—a feature becoming scarce in devices like the Honor 400, the iPhone 16, and the much pricier Galaxy S25 Edge. However, with advanced AI capabilities, some smartphones manage to compensate for this.

After conducting standard tests, I had the opportunity to try out the GT 7 under optimal conditions in Italy, using it intensively for several days. This experience allowed me to thoroughly assess its impressive battery life.

Moreover, Realme has had the GT 7’s video playback endurance certified by Guinness World Records. Setting a new benchmark: 24 hours of continuous playback without completely depleting the battery.

Realme GT 7Design

Despite its substantial battery, the GT 7 is not an overly bulky smartphone. It shares dimensions with the iPhone 16 Pro Max and is even lighter, weighing 206 grams.

A large 6.78-inch display adorns the front, featuring a cutout for the selfie camera. The screen is flat, surrounded by slim black bezels, providing a sleek, uniform appearance.

The chassis is made of brushed aluminum, embellished with a few buttons including a power button that adds a touch of color with its copper hue.

In terms of design innovation, Realme introduces a first with the GT 7’s back panel made not of glass or plastic, but graphene. This material is known for its superior heat conduction, up to six times more effective than glass, according to Realme. This choice is ideal for optimizing the cooling of the MediaTek chip, thus maximizing its performance.

The texture is silky and comfortable to hold. There are no fingerprint smudges to worry about, logically. The phone feels comfortable in the hand. While the front is flat, there’s a slight curvature on the back. Additionally, the edges are all beveled.

Realme includes a case in the box with the GT 7, but its utility is questionable as it impedes the advanced heat dissipation features. A protective film is pre-applied to the screen, and the phone boasts an IP69 certification, ensuring it can withstand high-pressure jets of water heated to 80°C.

Realme GT 7Screen

If you’re familiar with the GT 6, the screen on its successor doesn’t bring any surprises. It retains the same features: 6.78 inches, 120 Hz, AMOLED, HDR10+, Dolby Vision. This is a still-relevant combination that performs well.

However, it’s the calibration and maximum brightness that are of particular interest.

Realme promises 100% coverage of the DCI-P3 color space and a brightness of 1600 nits, peaking at 6000 nits.

Armed with our probe and the CalMAN Ultimate software from Portrait Displays, we set out to verify these claims.

By default, the display isn’t optimized, but switching to Cinematic color mode in the settings yields a finely-tuned setup. The color accuracy is perfectly maintained, as is the white point, resulting in an exceptional display with rich color nuances across both SRGB and DCI-P3, as promised.

As for brightness, it caps at 1585 nits in both SDR and HDR. We did not achieve the 6000-nit peak. While the SDR performance is adequate, we had hoped for over 2000 nits in HDR at this price point.

Realme GT 7Performance

Gone are the days of Qualcomm and its Snapdragon 8s Gen 3 that powered the GT 6. This year, Realme opts for MediaTek’s Dimensity 9400e. This chip is a slightly less capable version of the Dimensity 9400 seen delivering excellent performance on the Find X8 Pro.

Here, it’s paired with 12 GB of RAM. Realme promises gaming at 1.5K resolution with 120 fps and no latency.

The benchmarks we ran already place it well.

Compared to its counterpart from Oppo, it’s about 10% less powerful but significantly more affordable. It performs roughly on par with the iPhone 16 and its Apple A18.

However, this only holds true in its “balanced” mode, as Realme also offers a GT mode. Be warned, this mode is power-hungry and slightly diminishes the benefits of the large battery in the GT 7.

In our benchmarks, we noticed no difference between the two modes. It likely didn’t detect a game and thus did not activate the GT mode, even though it was enabled.

In gaming tests with Genshin Impact, the Realme GT 7 handled all the highest graphic settings without faltering in either balanced or GT mode, maintaining 60 fps. In power-saving mode, it still managed a solid 50 fps, dropping to 40 fps during combat.

In terms of long-term performance, it remains consistent. The combination of a vapor chamber and a graphene back panel proves effective.

In our stress test, there was a notable performance dip below 80% after 20 minutes, but it recovered. In GT mode, maintaining performance is more challenging, but the GT 7 optimizes its operation to regain momentum.

Interestingly, the device does not overheat. There’s only a slight warmth near the rear camera module, but it’s nothing unbearable.

Realme GT 7Software

The Realme GT 7 runs on Android 15 with Realme UI 6.0.

This is essentially the same interface we’ve seen on the GT 7 Pro earlier this year. It’s close to stock Android but offers many more customization options. The experience is enhanced by a sidebar that provides access to various shortcuts, including AI functions that are intelligently suggested based on the selected document. There’s also the AI Smart Loop that allows for dragging content from one app to another.

Translation, summary, reading, image editing—all tools adapt to the displayed content. However, not everything is available in French, such as the Summary function, for example.

There are only four bloatware apps (Facebook, Netflix, Amazon, and Temu), but at this price point, we’d prefer none at all.

Regarding updates, there’s good and bad news. Realme has extended its security update period to six years. However, major updates are limited to four years, as opposed to five years for the GT 7 Pro and the previous GT 6. This means longer safe usage but fewer new features.

Realme UI 6.0 includes a suite of artificial intelligence features called “NEXT AI.”

New functions debut with the GT 7 and GT 7T, such as the AI Planner, a proactive assistant that simplifies organization:

  • Simplified event creation: By tapping twice on the back of the phone, the AI analyzes the content displayed on the screen (a conversation, a concert poster, a booking email) and automatically generates an event in your calendar.
  • Advanced content analysis: The tool can decipher a group chat to determine the final date and time of a meeting, extract information from a poster on social networks, or recognize hotel booking details in an email to add it to your agenda.

There’s also the AI Coach, an AI trainer that offers real-time danger alerts and information about the game state (teammates, equipment, etc.).

The AI Translator is a translation tool that supports translation from screenshots, simultaneous interpretation, and face-to-face translation.

In photo editing, there’s a magic eraser, a tool for improving sharpness, another for removing blur, a third for reflections, and especially Landscape AI.


This feature enhances the depth of photos. It’s a really cool option to use as it adds material to the shots, reinforcing contrasts and making colors less dull. The result is flattering. Other functions are less conclusive.


Realme GT 7Photography

The GT 7 maintains a three-lens rear camera setup, complemented by a front-facing camera:

  • 50 MP Sony IMX906 wide-angle (f/1.88) with optical stabilization,
  • 50 MP Samsung S5KJN5 2x optical zoom (f/2.0),
  • 8 MP OV08D10 ultra-wide-angle (f/2.2).

The primary sensor has changed compared to the GT 6. It now supports video capture in 8K at 30 fps and 4K at 120 fps. The front camera has also been upgraded. It features a 32 MP Sony IMX615 (f/2.45) that records in 4K at 60 fps.

Wide-Angle

The main sensor is exceptionally fast. It can shoot 50 photos per second—a verified claim—and triggers in just a tenth of a second. With this sensor, blurred photos of moving scenes are a thing of the past. For instance, take this iconic Piaggio Ape van snapped on the fly in the streets of Rome. The result is
