Infinix Zero 20

  • Significantly faster 45W charging
  • Potentially more affordable price point
  • Stylish design (assumed based on Infinix branding)

  • Less powerful chipset (Helio G99)
  • Potentially less refined software experience
  • Likely inferior camera performance

Samsung Galaxy A73 5G

  • More powerful Snapdragon 778G 5G chipset
  • Samsung’s One UI offers a smoother experience
  • Superior camera capabilities (likely)

  • Slower 25W charging
  • Potentially higher price
  • Samsung’s software can include bloatware

Display Comparison

While both devices utilize 6nm chipsets, display details are missing. Assuming the A73 5G follows Samsung’s typical mid-range strategy, it likely features a Super AMOLED panel with a 120Hz refresh rate. The Zero 20, given its price point, may employ an LCD panel. The A73’s potential for higher peak brightness and superior color accuracy would be a significant advantage for outdoor visibility and media consumption. Bezels are likely comparable, but Samsung’s manufacturing process generally yields tighter tolerances.

Camera Comparison

Camera specifications beyond the main sensors are unavailable for the Zero 20. The A73 5G’s camera system, while not flagship-level, benefits from Samsung’s image processing expertise. The Snapdragon 778G’s ISP (Image Signal Processor) is also more capable than the Helio G99’s. While megapixel counts aren’t everything, a larger sensor size (likely on the A73) combined with a wider aperture will capture more light, resulting in better low-light performance. The A73’s OIS (Optical Image Stabilization) is a crucial advantage for steady videos and sharper photos in challenging conditions. We can assume the Zero 20 will include a suite of standard camera modes, but the A73 will likely offer more refined computational photography features.

Performance

The core difference lies in the chipsets. The Samsung Galaxy A73 5G’s Qualcomm Snapdragon 778G 5G (6nm) boasts a more powerful CPU configuration – a 1x2.4 GHz Cortex-A78 prime core alongside 3x2.2 GHz Cortex-A78 cores – compared to the Infinix Zero 20’s MediaTek Helio G99 (6nm) with its 2x2.2 GHz Cortex-A76 and 6x2.0 GHz Cortex-A55 setup. The A78 cores in the Snapdragon 778G offer a substantial performance uplift in both single-core and multi-core tasks. This translates to snappier app launches, smoother multitasking, and a more enjoyable gaming experience. The A73 also benefits from potentially faster LPDDR5 RAM, further enhancing performance.

Battery Life

The Infinix Zero 20’s 45W wired charging is a clear win, promising a 75% charge in just 30 minutes. The Samsung Galaxy A73 5G is limited to 25W charging, meaning a full charge will take considerably longer. However, battery life is not solely determined by charging speed. The efficiency of the chipset and software optimization play a significant role. While the exact battery capacities are unknown, the Snapdragon 778G’s 6nm process and optimized power management could potentially offset the charging speed difference, delivering comparable real-world battery life despite a potentially smaller capacity.

Buying Guide

Buy the Infinix Zero 20 if you prioritize rapid 45W charging and a sleek aesthetic, and are comfortable with a potentially less polished software experience. It’s ideal for users who frequently top up their phones and don’t heavily rely on intensive mobile gaming. Buy the Samsung Galaxy A73 5G if you value consistent performance, a more established brand ecosystem, and a smoother user interface. This phone is best suited for users who multitask frequently, enjoy mobile gaming, and appreciate Samsung’s One UI.

Frequently Asked Questions

❓ Does the MediaTek Helio G99 in the Infinix Zero 20 struggle with graphically demanding games like Genshin Impact?
The Helio G99 is a capable chipset, but it will likely require reduced graphics settings and frame rate caps to achieve a consistently smooth experience in demanding titles like Genshin Impact. The Snapdragon 778G in the A73 5G offers a more comfortable gaming experience with higher settings and fewer compromises.
❓ Is the 25W charging on the Samsung Galaxy A73 5G slow compared to other phones in this price range?
While 25W isn't the fastest charging available, it's still respectable. Samsung prioritizes battery health and long-term battery lifespan, which can sometimes come at the expense of peak charging speed. The A73’s efficient chipset may mitigate the slower charging somewhat, providing all-day battery life for moderate users.
❓ How does Samsung’s One UI compare to the software experience on the Infinix Zero 20?
Samsung’s One UI is a mature and feature-rich software experience, known for its customization options and smooth animations. Infinix’s software, while improving, often includes more pre-installed apps (bloatware) and may receive fewer software updates compared to Samsung’s commitment to several years of updates.
