The 6s Plus also introduced 4K video recording, a feature not available on the 6 Plus. Both have 1.2MP front-facing cameras.

Performance

The iPhone 6s Plus has a clear advantage with its Apple A9 chip and a dual-core 1.84 GHz Twister CPU compared to the iPhone 6 Plus's A8 chip and 1.4 GHz Typhoon CPU. This translates to noticeably faster app loading times, smoother multitasking, and better overall responsiveness on the 6s Plus. Both phones have 2GB of RAM.

Battery Life

The iPhone 6s Plus offers a slightly longer endurance rating (85h vs 79h), suggesting a bit more battery life in real-world usage. However, both phones are aging, and battery degradation is a significant concern with used models.

Buying Guide

The iPhone 6s Plus is a better choice for those prioritizing slightly faster performance and a more visible screen in bright sunlight. The iPhone 6 Plus remains a viable option for budget-conscious users who don't need the absolute latest features, but both are best suited for light use due to their age.

Frequently Asked Questions

❓ Is the iPhone 6s Plus worth buying in 2024?
It depends. If you need a large-screen phone on a tight budget and don't require the latest features, it can still be functional. However, be prepared for limited software updates and potential battery degradation.
