Apple phones are becoming increasingly durable, which cannot be attributed to Apple’s closed iOS system. The iPhone 6s, which was released seven years ago with iOS9 pre-installed and the first official upgrade from iOS10, can now be upgraded to iOS15. Now that the new iOS system upgrade has been supported for six years, will iOS10/11/12/13/14/15 be put to a battery life test to see which generation of iOS is best for the iPhone6S?

When running for 1 hour and 38 minutes, iPhone6S running iOS11.4.1 has the most remaining power, while iOS10.3.3 has the least. iOS15 and iOS13 are in first and second place, respectively, but the current power gap is not too large, according to the results.

The remaining power of iOS10 and 11 is the most at this time when the iPhone 6S is tested for 3 hours. Only these two systems have more than half of their battery life left, with iOS11 having more than 60%. With only 35% remaining power, iOS14.7 is the least powerful. iOS15 isn’t quite as good, with only 38% battery life remaining. The performance of iOS 12 and 13 is average.

Only iOS 11.4.1 had 8% battery life left after 5 hours and 36 minutes of testing. The remaining five operating systems have all been depleted. Even the most recent support iOS15.3.1 has shut down after only 4 hours and 36 minutes of testing, indicating that the new system is not friendly to the iPhone 6S battery life.
