The UnboxingTN Verdict

out of 100

The iPhone 6s Plus still offers cohesive software and solid construction, but aging performance, a small battery, and slow charging limit it today.

What is good

  • iOS provides a cohesive software experience.
  • The 5.5-inch Retina HD display delivers 1080 × 1920 resolution.
  • The 12 MP main camera includes optical image stabilization.

What is not

  • The 2750 mAh battery severely limits endurance.
  • 5 W charging is notably slow.
  • The Apple A9 chip and 2 GB RAM feel dated for demanding use.

How the score breaks down

  • Performance 15
  • Camera 47
  • Display 43
  • Battery 8
  • Connectivity 57
  • Build 68
  • Software 95
