问题
I want to know if there is any way I can get the percentage of battery usage for each app used by the user in iOS using Swift 2. It is like in Settings > Battery and there will be a battery usage group. Please help

No, there is no simple "show me a battery usage breakdown by app" option. It is quite complex to figure out what factors lead to battery drain.
