Apple's latest update for iOS might be killing your battery.

Users who have updated (about 21-percent of users have done so already) have taken to social media to complain about a very noticeable decline in their battery power. The update, iOS 7.1, is for iPads and iPhones. 

Yet, some users have said that their power has improved, so the bug could be limited to only a few users. Have you noticed anything different with your battery power after updating?
