Oppo Reno3 Pro 5G

  • Faster 30W charging for quick power-ups
  • Slightly brighter display for better outdoor visibility
  • Potentially better thermal management (speculative)

  • Lower battery endurance (100 hours)
  • Less consistent software updates compared to Pixel

Google Pixel 5a 5G

  • Superior battery life (122 hours)
  • Clean Android experience with guaranteed updates
  • Google’s renowned computational photography

  • Slower 18W charging
  • Slightly dimmer display compared to Reno3 Pro

Display Comparison

Both devices feature displays with an infinite (nominal) contrast ratio, indicating excellent black levels. However, the Pixel 5a 5G edges out the Reno3 Pro 5G with a measured peak brightness of 861 nits compared to the Reno3 Pro’s 819 nits. This difference, while not massive, translates to better visibility under direct sunlight. Both utilize the same Snapdragon 765G chipset for graphics rendering, so gaming experience will be similar, but the brighter screen on the Pixel 5a 5G will be more enjoyable outdoors.

Camera Comparison

Both devices are listed with 'Photo / Video' capabilities, lacking specific sensor details. This makes a direct comparison difficult. However, Google’s Pixel line is renowned for its computational photography prowess, leveraging software algorithms to produce excellent images even with potentially less impressive hardware. The Reno3 Pro 5G likely relies more on hardware specifications, but without knowing sensor size or aperture, it’s impossible to definitively state which camera is superior. The absence of detail regarding OIS (Optical Image Stabilization) on either device is a notable omission.

Performance

Critically, both phones are powered by the Qualcomm Snapdragon 765G 5G (7nm) chipset, featuring the same octa-core CPU configuration. This means raw processing power is virtually identical. Performance will be comparable for everyday tasks and moderate gaming. Thermal management, however, isn’t specified, and could be a differentiating factor. Given the Reno3 Pro’s faster charging, it *may* have a slightly more robust thermal solution, but without testing data, this remains speculative. The identical chipset means RAM speed and architecture are also the same, negating any performance advantage here.

Battery Life

The most significant difference lies in battery endurance. The Pixel 5a 5G boasts a 122-hour endurance rating, a substantial improvement over the Reno3 Pro 5G’s 100 hours. This translates to a full day or more of typical usage on the Pixel 5a 5G. While the Reno3 Pro 5G offers faster 30W wired charging (50% in 20 minutes) compared to the Pixel 5a 5G’s 18W charging with PD2.0, the Pixel’s longer battery life reduces the need for frequent top-ups. The Reno3 Pro’s faster charging is beneficial for users who frequently run out of power, but the Pixel 5a 5G’s longevity is a more consistent advantage.

Buying Guide

Buy the Oppo Reno3 Pro 5G if you need faster charging speeds and prioritize a slightly brighter display for outdoor visibility. Buy the Google Pixel 5a 5G if you prefer exceptional battery life, a clean Android experience with guaranteed updates, and a more consistent camera performance thanks to Google’s computational photography.

Frequently Asked Questions

❓ Does the Snapdragon 765G in either phone struggle with demanding games like Genshin Impact?
While the Snapdragon 765G is a capable mid-range chip, demanding titles like Genshin Impact will require reduced graphics settings on both the Reno3 Pro 5G and Pixel 5a 5G to maintain a stable frame rate. The identical chipset means performance will be very similar, but thermal throttling could become a factor during extended gaming sessions.
❓ How does the Pixel 5a 5G's software update policy compare to the Oppo Reno3 Pro 5G?
Google guarantees at least 3 years of Android OS updates and 5 years of security updates for the Pixel 5a 5G. Oppo’s update policy for the Reno3 Pro 5G is less consistent and typically shorter, meaning the Pixel 5a 5G will remain secure and feature-rich for a longer period.
❓ Is the 18W charging on the Pixel 5a 5G noticeably slower than the 30W charging on the Reno3 Pro 5G in real-world use?
Yes, the 30W charging on the Reno3 Pro 5G will charge the phone significantly faster than the 18W charging on the Pixel 5a 5G. However, the Pixel 5a 5G’s superior battery life means you’ll likely need to charge it less frequently, mitigating the slower charging speed.
