Background and Market Position

The Realme 7 5G was launched in Europe (starting with Spain and Germany) in November 2020, with a starting price of €279 for the 6GB/128GB model. It was one of the first phones to bring the Dimensity 800U to the sub-€300 segment, competing directly with the Xiaomi Mi 10T Lite and the Poco X3 NFC (though the latter was 4G-only in most regions). Realme positioned it as a “5G speedster” for young users who wanted smooth scrolling and future-proof connectivity without paying flagship prices.

The Dimensity 800U was a step up from the Dimensity 720 used in the Realme X7 series, offering better CPU performance and integrated 5G modem. It supported dual-SIM 5G standby, which was rare at that price. The 120Hz LCD was also notable because most 120Hz phones at the time used AMOLED panels or cost more.

Performance and Real-World Usage

The Dimensity 800U is a capable mid-range chip. In daily use, the Realme 7 5G handles social media, web browsing, and video streaming without stutter. The 120Hz display makes scrolling feel noticeably smoother than 60Hz, though the LCD panel’s colors and contrast are not as vivid as AMOLED.

For gaming, the phone runs popular titles like PUBG Mobile at “Balanced” graphics and 60fps, and Call of Duty Mobile at “Medium” quality. Heavy games like Genshin Impact will run but with lower settings and occasional frame drops. The phone does warm up under sustained load, but the plastic back helps dissipate heat. The 5,000mAh battery easily lasts a full day of moderate use; with heavy gaming, expect around 6–7 hours of screen-on time.

Camera System Deep Dive

The 48MP main camera uses a Sony IMX586 sensor (same as many 2019 flagships). In daylight, photos are sharp with good dynamic range. At night, the dedicated Night Mode brightens scenes but can introduce noise. The 8MP ultrawide is decent for landscapes but lacks detail in low light. The 2MP macro and depth sensors are largely gimmicks—they add little value, and most users will stick to the main and ultrawide.

Video recording tops out at 4K/30fps on the main camera, with electronic image stabilization (EIS) available at 1080p/30fps. The front 16MP camera is adequate for selfies and video calls, though skin tones can look slightly oversaturated.

Software and Updates

The Realme 7 5G launched with Realme UI based on Android 10. It received Android 11 and Android 12 updates, but as of 2024, it is no longer receiving major OS updates. Security patches may continue for a while, but users should expect the phone to be left behind in terms of new features. The UI is clean but includes some pre-installed apps and promotional notifications, which can be disabled.

Common Problems and How to Avoid Them

Battery drain on 5G: 5G can be power-hungry. If you don’t need it, switch to 4G in settings to extend battery life.
Display ghost touch: Some users reported ghost touches on the 120Hz panel. A factory reset or software update often fixes it; if not, contact support.
Slow charging with non-Dart chargers: The phone supports 30W Dart Charge, but using a standard USB-PD charger will charge at a slower rate (around 10W). Always use the included charger for fastest speeds.
Storage filling up: The 128GB fills quickly with photos and games. Use a microSD card (up to 256GB) to expand.

How to Choose: Is It Still Worth It in 2024?

In 2024, the Realme 7 5G is no longer a new phone, but you might find it refurbished or on clearance. Consider these factors:

5G support: It supports sub-6GHz 5G, which works on most networks. Good for future-proofing if you haven’t upgraded yet.
Display: 120Hz is still a premium feature, even on budget phones.
Battery: 5,000mAh is above average even today.
Software updates: It won’t get Android 13 or later. If you value updates, look for a newer budget phone.
Alternatives: Newer phones like the Realme 11 series or Samsung Galaxy A14 offer better cameras and longer support, but cost more.

Frequently Asked Questions

Does the Realme 7 5G support 120Hz on all apps?

No, the phone automatically adjusts the refresh rate based on the app. Some apps like YouTube and Google Maps are locked to 60Hz to save battery. You can force 120Hz in developer options, but that may cause stutter in apps that aren’t optimized.

Can I use two 5G SIM cards simultaneously?

Yes, the Dimensity 800U supports dual-SIM dual-standby (DSDS) with 5G on both slots. However, using two 5G SIMs can increase battery drain. You can set one SIM to 4G to save power.

Is the Realme 7 5G waterproof?

No, it has no official IP rating. It has a plastic body and a rubber seal around the SIM tray, but you should avoid exposing it to water or heavy rain.

How long does the battery last with 120Hz enabled?

With 120Hz always on, expect around 8–9 hours of screen-on time with light to moderate use. With 60Hz, you might get 10–11 hours. Gaming will reduce that to 5–6 hours.

Can I expand the storage?

Yes, there is a dedicated microSD slot that supports cards up to 256GB. You can use it without removing a SIM card.

Does the phone support wireless charging?

No, it only supports wired charging via the 30W Dart Charge adapter. Wireless charging is not available.
