Apple latest iOS version may have included under-the-hood changes that improve battery life to surpass even the respectable performance reported for iOS 6, claims ZDNet. This information comes from journalist Adrian Kingsley-Hughes, who has been tracking battery life in his iPhone 5 since the handset’s release.

According to Kingsley-Hughes, iOS 7.1 battery performance took a nose dive, with the battery meter dropping to 48 percent after six hours of use. Under iOS 7.1.1, his performance was significantly improved with the battery meter only dropping to 76 percent after six hours of usage.

“Then came iOS 7.1.1. Following this update I’ve noticed that things have improved dramatically, and now battery life is only falling to around 76 percent per six hours of average use, which is better than what I was getting pre iOS 7.0. Can’t grumble with that.”

This is a difference of 26 percentage points during the same period and a significant improvement for someone who needs their battery to last an entire day. Kingsley-Hughes also notes this iOS 7.1.1 performance compares favorably to his pre-iOS 7 performance, which would see a drop to 74 percent after six hours.
