Apple iPhone 6s Plus

  • Superior battery life
  • Larger display for media
  • Slightly better sunlight visibility
  • Potentially better multitasking (due to RAM)

  • Larger and heavier
  • Less pocketable
  • Can be unwieldy for one-handed use

Apple iPhone 6s

  • More compact and lightweight
  • Easier to use one-handed
  • More pocketable

  • Shorter battery life
  • Smaller display
  • Slightly worse sunlight visibility

Display Comparison

Both phones feature a 4.7-inch (6s) and 5.5-inch (6s Plus) Retina HD display with 3D Touch. The 6s Plus boasts a slightly better contrast ratio (1382:1 vs 1481:1 nominal, 3.530 vs 3.783 sunlight), resulting in marginally better visibility in bright conditions. The larger screen of the Plus is ideal for watching videos and browsing, while the 6s is more comfortable to hold and use one-handed.

Camera Comparison

The camera systems are essentially the same: a 12MP rear camera and a 5MP front camera. Image quality is comparable in good lighting conditions. Low-light performance is adequate for their time, but not exceptional by today's standards. Video recording capabilities are also similar, both supporting 4K video recording.

Performance

Both devices are powered by the Apple A9 chip and a dual-core 1.84 GHz Twister CPU. Performance is virtually identical in everyday tasks and most apps. While older, they can still handle many modern apps, though demanding games might show some limitations. The 6s Plus has slightly more RAM (2GB vs 3GB), which *could* offer a marginal advantage in multitasking, but it's unlikely to be noticeable in most scenarios.

Battery Life

This is where the 6s Plus truly shines. It has a significantly larger battery (2915 mAh) compared to the 6s (1810 mAh), resulting in a much longer endurance rating (85h vs 62h). This translates to significantly more screen-on time and less frequent charging for the 6s Plus.

Buying Guide

Who should buy the iPhone 6s Plus? Users who prioritize battery life and a larger screen for media consumption and productivity. Who should buy the iPhone 6s? Those seeking a more compact and manageable device for everyday use, prioritizing portability over extended battery life.
