LG K20 (2019)

  • More powerful processor (A10 Fusion)
  • Superior camera image processing
  • Access to Apple’s ecosystem

  • Older design and smaller screen
  • Aging battery health
  • Limited storage options

Apple iPhone 7

  • Larger screen size (likely)
  • Expandable storage via microSD
  • More modern Android OS

  • Significantly slower processor (MT6739)
  • Less refined camera performance
  • Potentially slower software updates

Display Comparison

Both devices share a similar contrast ratio of 1603:1 (nominal) and 3.964 (sunlight), suggesting comparable outdoor visibility. However, the iPhone 7’s smaller 4.7-inch display likely offers a higher pixel density than the LG K20’s unspecified screen size, resulting in a sharper image. The K20 benefits from a more recent manufacturing date, potentially avoiding some of the display degradation common in older iPhone 7 units.

Camera Comparison

While both phones offer photo and video capabilities, the iPhone 7’s image signal processor (ISP) within the A10 Fusion provides superior image processing. Although sensor sizes aren’t specified, Apple’s computational photography algorithms consistently deliver better dynamic range and detail. The LG K20 likely relies more heavily on software enhancements to compensate for a potentially less capable sensor. The iPhone 7’s video recording capabilities are also expected to be superior, offering better stabilization and quality.

Performance

The Apple A10 Fusion, fabricated on a 16nm process, is the dominant force here. Its quad-core configuration (2x Hurricane + 2x Zephyr) running at 2.34 GHz delivers significantly more processing power than the LG K20’s Mediatek MT6739 (28nm) and its quad-core 1.5 GHz Cortex-A53 cores. This translates to faster app loading times, smoother multitasking, and a more responsive overall experience on the iPhone 7. The A10 Fusion’s architecture also provides a more capable GPU for gaming and graphics-intensive tasks. The K20’s MT6739 will struggle with demanding applications.

Battery Life

Interestingly, both devices share an endurance rating of 61 hours, despite the LG K20 likely having a larger battery capacity due to its larger size. This suggests the iPhone 7’s more efficient A10 Fusion chip and iOS optimization contribute to comparable battery life. However, the iPhone 7’s battery has aged significantly since its release, meaning real-world performance will likely be lower than the K20’s, especially if the iPhone 7’s battery hasn’t been replaced.

Buying Guide

Buy the LG K20 (2019) if you need a large-screen Android device with expandable storage and are comfortable with a slower processor and less refined software experience. Buy the Apple iPhone 7 if you prioritize a responsive user interface, a more capable camera, and access to Apple’s ecosystem, even if it means accepting an older design and potentially reduced battery health.

Frequently Asked Questions

❓ Is the Mediatek MT6739 in the LG K20 powerful enough for modern mobile games?
The Mediatek MT6739 is a budget chipset and will struggle with graphically demanding games. While it can handle simpler titles, expect low frame rates and reduced graphical settings in popular games like PUBG or Call of Duty Mobile. The iPhone 7’s A10 Fusion offers a much smoother gaming experience.
❓ How does the aging battery on the iPhone 7 affect its usability in 2024?
The iPhone 7’s battery has likely degraded significantly over time. Expect shorter battery life compared to a new device, potentially requiring a mid-day charge with moderate use. Apple offers battery replacement services, which can restore much of the original battery life, but this adds to the overall cost.
❓ Does the LG K20 support software updates and security patches?
The LG K20 (2019) is unlikely to receive major Android version updates at this point. Security patches may be infrequent or nonexistent, posing a potential security risk. The iPhone 7, while also no longer receiving major iOS updates, generally receives security updates for a longer period than Android devices in this price range.
