Umidigi A13S

  • Potentially longer software support from Umidigi.
  • Slightly newer chipset architecture.
  • Lower price point (potentially).

  • Less powerful chipset overall.
  • Less efficient 12nm process.
  • Likely lower display brightness.

Samsung Galaxy A04s

  • More powerful and efficient Exynos 850 chipset.
  • Faster 15W charging.
  • Brighter display for better outdoor visibility.

  • Older chipset generation.
  • Samsung’s software update policy can be inconsistent.
  • May be slightly more expensive.

Display Comparison

The Samsung Galaxy A04s boasts a significantly brighter display, reaching 389 nits compared to an unlisted value for the Umidigi A13S, suggesting a lower peak brightness. Both share a 1614:1 contrast ratio, indicating similar color reproduction capabilities. However, the A04s’ higher brightness makes it more usable outdoors. The lack of information regarding the A13S’s panel type suggests it likely utilizes a less advanced technology than the A04s, potentially impacting viewing angles and color accuracy.

Camera Comparison

Both phones offer 'Photo / Video' capabilities, but detailed camera specifications are lacking. Without sensor size or aperture information, a direct comparison is difficult. However, given the market segment, it’s reasonable to assume both utilize budget sensors. The presence of a 2MP macro camera on the A04s is unlikely to provide significant photographic value, serving primarily as a feature checkbox. Image processing will likely be a key differentiator, with Samsung’s software generally offering more refined results.

Performance

The core difference lies in the chipsets. The Samsung Galaxy A04s’ Exynos 850, built on an 8nm process, features an octa-core configuration (4x2.0 GHz Cortex-A55 & 4x2.0 GHz Cortex-A55). This contrasts with the Umidigi A13S’ Unisoc Tiger T310 (12nm) which uses a quad-core setup (1x2.0 GHz Cortex-A75 & 3x1.8 GHz Cortex-A55). While the A75 core in the A13S is more powerful individually, the A04s’ eight A55 cores and more efficient process node provide superior multi-tasking and sustained performance. The 12nm process of the T310 will likely result in higher temperatures and potential throttling under load.

Battery Life

Both devices achieve an endurance rating of 114 hours, suggesting comparable battery life despite the Umidigi A13S’s unspecified battery capacity. However, the Samsung Galaxy A04s supports 15W wired charging, while the A13S is limited to 10W. This means the A04s will recharge significantly faster, reducing downtime. The Exynos 850’s 8nm efficiency also contributes to better power management, potentially offsetting any capacity difference.

Buying Guide

Buy the Umidigi A13S if you prioritize a potentially longer software update cycle from a smaller manufacturer and are comfortable with a less polished user experience. Buy the Samsung Galaxy A04s if you value a smoother, more responsive experience, a brighter display, and the reliability of Samsung’s software ecosystem, even if it means an older chipset.

Frequently Asked Questions

❓ Does the Exynos 850 in the Galaxy A04s tend to overheat during prolonged gaming sessions?
The Exynos 850 is a relatively efficient chipset. While it may warm up during extended gaming, its 8nm process and thermal design should prevent significant overheating or throttling, providing a more consistent gaming experience than the Umidigi A13S’s Unisoc Tiger T310.
❓ Is the 2MP macro camera on the Samsung Galaxy A04s actually useful for taking detailed close-up photos?
Generally, 2MP macro cameras on budget phones offer limited detail and image quality. While it can capture close-up shots, expect soft images and a lack of sharpness. It’s more of a novelty feature than a genuinely useful camera tool.
❓ Can the Samsung Galaxy A04s handle popular games like PUBG Mobile at reasonable frame rates?
The Exynos 850 can run PUBG Mobile, but expect to play at medium graphics settings and potentially lower frame rates (around 30-40fps) for a smooth experience. The A13S may struggle to maintain consistent frame rates even at lower settings due to its less powerful chipset.
❓ How does the software update support compare between Umidigi and Samsung?
Samsung generally provides more consistent software updates, including security patches, for a longer period than smaller manufacturers like Umidigi. While Umidigi may offer updates, they are often less frequent and may not be guaranteed for the same duration as Samsung’s support.
