Samsung Galaxy S7 edge (USA)

  • Superior battery endurance (87h rating)
  • More affordable price point (post-launch)
  • Mature and refined software experience

  • Older Snapdragon 820 chipset
  • Slower charging speed (15W QC2)

Sony Xperia XZ Premium

  • Latest Snapdragon 835 chipset for faster performance
  • Faster charging with Quick Charge 3.0 (18W)
  • Superior display contrast in sunlight

  • Lower battery endurance (72h rating)
  • Potentially higher price (at launch)

Display Comparison

Both devices feature displays with a nominal contrast ratio of 1238:1, but the Xperia XZ Premium significantly improves upon this with a sunlight contrast ratio of 2.877:1, indicating superior visibility outdoors. While both likely utilize IPS LCD technology (given the era), the XZ Premium’s higher contrast suggests enhanced polarization or backlighting. The S7 edge’s curved display, while aesthetically pleasing, doesn’t offer a quantifiable advantage in image quality over the XZ Premium’s flat panel. Neither specification details resolution, but both were flagship devices and likely featured QHD displays.

Camera Comparison

Both devices are described as having photo/video capabilities, but detailed sensor information is absent. Given Sony’s expertise in image sensors, the XZ Premium likely benefits from a more advanced sensor and image processing pipeline. The XZ Premium’s inclusion of Sony’s SteadyShot technology (not explicitly stated, but a brand hallmark) suggests superior video stabilization. The S7 edge’s camera was highly regarded in its time, but the XZ Premium’s newer hardware and software likely provide better low-light performance and dynamic range. The lack of detail regarding megapixel counts or aperture values makes a precise comparison impossible.

Performance

The Sony Xperia XZ Premium’s Qualcomm MSM8998 Snapdragon 835, built on a 10nm process, represents a significant architectural leap over the Samsung Galaxy S7 edge’s Qualcomm MSM8996 Snapdragon 820 (14nm). The 835’s octa-core CPU (4x2.45 GHz Kryo & 4x1.9 GHz Kryo) offers a substantial performance increase over the S7 edge’s quad-core configuration (2x2.15 GHz Kryo & 2x1.6 GHz Kryo). The smaller 10nm node also translates to improved thermal efficiency, potentially reducing throttling during sustained workloads. While the S7 edge remains capable, the XZ Premium delivers a smoother, more responsive experience, particularly in demanding applications.

Battery Life

Despite having a smaller battery capacity, the Sony Xperia XZ Premium’s 18W wired charging with Quick Charge 3.0 support offers a faster charging experience than the S7 edge’s 15W Quick Charge 2.0. However, the S7 edge boasts a significantly higher endurance rating of 87 hours compared to the XZ Premium’s 72 hours. This suggests that, despite the faster charging, the S7 edge provides longer overall usage between charges, likely due to the more efficient Snapdragon 820 and optimized software.

Buying Guide

Buy the Samsung Galaxy S7 edge (USA) if you need exceptional battery endurance, a mature software experience, and a device that’s readily available at a lower price point. Buy the Sony Xperia XZ Premium if you prioritize the latest processor technology, faster charging speeds, and a display optimized for high contrast viewing, even in direct sunlight.

Frequently Asked Questions

❓ Does the Snapdragon 820 in the Galaxy S7 edge struggle with modern apps?
While the Snapdragon 820 was a flagship processor in its time, newer applications and games may exhibit slightly longer loading times or reduced frame rates compared to the Snapdragon 835 in the Xperia XZ Premium. However, for everyday tasks and most mainstream games, the S7 edge remains perfectly capable.
❓ Is the difference in charging speed between 15W and 18W noticeable in real-world use?
Yes, the 18W charging on the Xperia XZ Premium will noticeably reduce charging times. While both support Quick Charge, the higher wattage translates to a faster 0-100% charge, especially beneficial for users who frequently need to top up their battery quickly.
❓ Given the battery endurance difference, will the XZ Premium require more frequent charging?
The Xperia XZ Premium’s lower endurance rating of 72 hours suggests it will likely require more frequent charging than the S7 edge’s 87-hour rating. This is particularly true for heavy users who consume a lot of media or play demanding games.
