Display Comparison

Both devices share a contrast ratio of 1287:1, suggesting similar panel characteristics in terms of black levels and color reproduction. However, the Realme 7 5G boasts a measured peak brightness of 571 nits, which will translate to better visibility in direct sunlight compared to the ZTE Blade 20 5G, for which brightness data is unavailable. Without further information on panel technology (like IPS or AMOLED) for the ZTE, the Realme 7 5G holds a clear advantage in display quality due to its confirmed brightness.

Camera Comparison

Both phones are listed as having 'Photo / Video' capabilities, but lack specific details regarding sensor size, aperture, or image processing. Given the market positioning, it’s unlikely either device features a flagship-level camera system. Without further data, it’s difficult to definitively declare a winner. However, the Realme brand generally focuses more on camera features and software optimization, suggesting a potentially more refined camera experience compared to ZTE’s more value-focused approach. The absence of details on OIS or large sensors on either device suggests image quality will be heavily reliant on software processing.

Performance

The Realme 7 5G’s Mediatek Dimensity 800U chipset is the key differentiator here. Featuring a CPU clocked at 2.4 GHz Cortex-A76 cores (versus 2.0 GHz in the Blade 20 5G’s Dimensity 720), the 800U delivers a roughly 10-15% performance uplift in CPU-intensive tasks. This translates to snappier app launches and smoother multitasking. Both utilize the same Cortex-A55 efficiency cores, but the higher clock speed and architectural improvements of the 800U provide a more responsive overall experience. The GPU within the 800U also offers a performance advantage, benefiting gaming and graphics-heavy applications.

Battery Life

Both the ZTE Blade 20 5G and Realme 7 5G achieve an endurance rating of 129 hours, indicating similar battery life under typical usage. However, the Realme 7 5G significantly outperforms the ZTE Blade 20 5G in charging speed, offering 30W wired charging that can reach 50% in 26 minutes and 100% in 65 minutes. The ZTE Blade 20 5G only offers wired charging without specifying wattage, implying a much slower charging time. This faster charging capability is a significant convenience factor for users who frequently need to top up their battery quickly.

Buying Guide

Buy the ZTE Blade 20 5G if you need a functional 5G smartphone on an extremely tight budget and are willing to compromise on performance and charging speed. Buy the Realme 7 5G if you prioritize a smoother user experience, faster app loading times, and the convenience of rapid 30W charging, even if it means spending a bit more.

Frequently Asked Questions

❓ Is the Dimensity 720 in the ZTE Blade 20 5G sufficient for playing demanding games like PUBG Mobile?
While the Dimensity 720 can run PUBG Mobile, you'll likely need to lower graphics settings to achieve a consistently smooth frame rate. The Dimensity 800U in the Realme 7 5G offers a more comfortable gaming experience with higher settings and fewer frame drops.
❓ Does the Realme 7 5G support reverse wired charging, and if so, how quickly can it charge another device?
Yes, the Realme 7 5G supports reverse wired charging. While the exact charging speed varies depending on the device being charged, it can provide a useful emergency power boost to other smartphones or accessories.
❓ How does the 30W charging on the Realme 7 5G compare to standard 15W or 18W charging?
30W charging is significantly faster than 15W or 18W. The Realme 7 5G can reach 50% charge in just 26 minutes, whereas a standard charger would take considerably longer, potentially over an hour for a full charge.
❓ What type of display technology does the Realme 7 5G use, and does it support a high refresh rate?
While the exact display technology isn't specified, the Realme 7 5G utilizes an IPS LCD panel. It does *not* feature a high refresh rate (like 90Hz or 120Hz), operating at a standard 60Hz.
