I have an iPhone 5s currently running iOS 8.3. I am very scared to update my phone to iOS 9.2.1 because of this so called battery charge level bug as mentioned in this link. https://support.apple.com/en-us/HT205727 http://thenextweb.com/apple/2016/01...nd-6s-plus-to-show-wrong-battery-charge/#gref Just want to confirm if this bug ONLY affects iPhone 6s/6s Plus and NOT the iPhone 5s ??? So in other words, if I update my phone to iOS 9.2.1 on my iPhone 5s, will I be affected by this bug as well? Thanks!
