In this article, we delve into a comprehensive comparison between the performance and battery life of iOS 17 and iOS 16 on three different iPhone models: iPhone 15, iPhone 14, and iPhone 11.
It’s essential to note that the iPhone 14 has been on the market for a year, potentially leading to slightly degraded battery health compared to the relatively new iPhone 15. However, the iPhone 15 may not initially demonstrate optimal battery performance due to its recent purchase and the need for optimization over a few days.
Performance
In terms of performance, both the iPhone 14 and the iPhone 15 exhibit similar capabilities, with virtually no noticeable differences. Both devices launch games almost simultaneously, delivering smooth experiences without performance hiccups. However, it’s worth noting that the iPhone 15 experienced more significant heating issues during testing, potentially affecting game fluidity. This discrepancy might be attributed to software and hardware optimization, and it’s expected to improve with future iOS 17.1 updates.
Battery
Battery health is a crucial aspect to consider, and it’s essential to highlight that updating the iPhone 14 to iOS 17 resulted in a battery recalibration. This recalibration caused a slight drop in battery health percentage, reaching 89% within a year, which some may consider concerning.
To assess whether iOS 17 enhances battery performance compared to iOS 16, tests were conducted with iOS 16.6 and iOS 17 on the iPhone 14:
- iPhone 14 with iOS 16.6:
- Start: 100%
- 30 minutes: 80%
- 60 minutes: 55%
- 90 minutes: 45%
- 180 minutes: 11%
- Note: After 50 minutes, the device experienced significant heat, which is normal during intensive gaming.
- iPhone 14 with iOS 17:
- Start: 100%
- 30 minutes: 85%
- 60 minutes: 75%
- 90 minutes: 50%
- 120 minutes: 30%
- 180 minutes: 15%
- Note: After 60 minutes, the device experienced significant heat, which is normal during intensive gaming.
The testing revealed that iOS 17 initially optimizes battery performance better than iOS 16.6. However, as the battery percentage decreases, iOS 17’s discharge rate accelerates, which is not observed with iOS 16.6. In contrast, iOS 16.6 exhibits a more consistent decline in performance.
iOS 17 on iPhone 13 and 14
The experience of using iOS 17 on both the iPhone 13 and 14 has been quite positive. The update adapted well to the devices, offering strong performance and compatibility with third-party applications. Benchmark results indicate similar single-core and multi-core scores between iOS 16.6.1 and iOS 17, with slight variations.
iOS 17 on iPhone 11
The iPhone 11, which is approaching the end of its update cycle, exhibited very good performance with iOS 17. Daily tasks ran smoothly, and benchmark scores remained consistent. With further optimizations in future iOS 17 updates, performance is expected to improve.
It’s important to acknowledge that Apple may have hidden certain iOS 17 features to maintain performance. Consequently, users may experience a diluted version of iOS 17 or a reduction in features compared to previous versions. This trend of offering fewer features over time is a notable shift in Apple’s approach.
