Infinix Zero X

  • Faster initial charging speed (40% in 15 mins)
  • Potentially more affordable price point
  • Helio G95 offers decent everyday performance

  • Inferior chipset compared to Snapdragon 860
  • Less efficient 12nm process node
  • Limited display information available

Xiaomi Poco X3 Pro

  • Significantly more powerful Snapdragon 860 chipset
  • Better thermal management for sustained performance
  • 120Hz display for smoother visuals

  • Slower initial charging speed compared to Infinix Zero X
  • May be slightly more expensive
  • Charging takes almost an hour for a full charge

Display Comparison

Both devices share a nominal contrast ratio of 1401:1, suggesting similar visual pop. However, detailed display specs like peak brightness, color gamut coverage, and panel type are missing for the Infinix Zero X. The Poco X3 Pro’s display, while not exceptional, is known for its 120Hz refresh rate, which contributes to smoother scrolling and gaming. Without comparable data for the Zero X, it’s difficult to assess its display quality beyond the shared contrast ratio. The absence of LTPO technology on either device means they won't dynamically adjust refresh rates for power saving.

Camera Comparison

Both phones feature 'Photo / Video' capabilities, but lack specific details regarding sensor size, aperture, or image processing algorithms. The absence of this information makes a direct comparison challenging. However, given the market positioning, it’s likely the Poco X3 Pro benefits from Qualcomm’s image signal processor (ISP), which generally provides superior image quality and video stabilization. The prevalence of 2MP macro lenses on both devices suggests they are largely marketing features with limited practical utility. Without detailed camera specs, it’s difficult to definitively declare a winner, but the Poco X3 Pro likely holds an advantage due to its chipset’s ISP.

Performance

The core difference lies in the chipsets. The Xiaomi Poco X3 Pro’s Qualcomm Snapdragon 860 (7nm) is a significant step up from the Infinix Zero X’s MediaTek Helio G95 (12nm). The Snapdragon 860’s Kryo 485 Gold cores, clocked up to 2.96 GHz, deliver substantially higher single-core and multi-core performance. The 7nm process node also translates to better thermal efficiency, reducing the likelihood of throttling during extended gaming sessions. While the Zero X’s Cortex-A76 cores offer respectable performance, they simply can’t match the Snapdragon 860’s raw power. The Poco X3 Pro is the clear winner for demanding applications and gaming.

Battery Life

Both devices boast an endurance rating of 112 hours, indicating comparable battery life under typical usage. However, their charging speeds differ significantly. The Infinix Zero X supports 45W wired charging, claiming a 40% charge in 15 minutes. The Poco X3 Pro, with 33W charging, takes 30 minutes for 59% and 59 minutes for a full charge. While the Zero X charges faster initially, the Poco X3 Pro’s overall charging time isn’t drastically slower. The comparable endurance ratings suggest that the more efficient Snapdragon 860 in the Poco X3 Pro offsets the slightly slower charging speed.

Buying Guide

Buy the Infinix Zero X if you prioritize extremely fast charging and frequently top up your phone throughout the day. Its 45W charging is a clear advantage. Buy the Xiaomi Poco X3 Pro if you’re a gamer or power user who demands consistent performance, longer gaming sessions, and a more robust chipset capable of handling demanding tasks. The Snapdragon 860 offers a noticeable edge in sustained performance.

Frequently Asked Questions

❓ Will the Poco X3 Pro’s Snapdragon 860 overheat during prolonged gaming sessions?
The Snapdragon 860 is known for its relatively efficient thermal performance. While some throttling is possible during extremely demanding games, the 7nm process node and Qualcomm’s thermal management features help mitigate overheating, providing a more consistent gaming experience compared to the 12nm Helio G95 in the Infinix Zero X.
❓ Is the 45W charging on the Infinix Zero X significantly faster in real-world use than the Poco X3 Pro’s 33W charging?
While the Infinix Zero X charges faster initially (40% in 15 minutes), the Poco X3 Pro’s 33W charging isn’t drastically slower. A full charge takes 59 minutes, which is only moderately longer than the time it would take to reach a similar charge level on the Zero X. The difference in charging speed is noticeable, but not a game-changer.
❓ Does the Poco X3 Pro support high refresh rate gaming, like 90fps or 120fps in popular titles?
The Poco X3 Pro’s 120Hz display and powerful Snapdragon 860 chipset allow for high refresh rate gaming in many popular titles, such as PUBG Mobile and Call of Duty Mobile. However, achieving consistently high frame rates depends on the game’s settings and optimization. Expect to be able to push frame rates higher than the Infinix Zero X.
