Once you’ve seen how battery intensive certain apps are you can shut them down completely to prevent them running even when you’re not using them.
Internet phone call apps such as Skype, apps using your location, music‑playing apps, those using Newsstand, and apps connected with an external accessory use up more battery power. Try closing these from the multitasking view by swiping up on any app screenshot to see if the device’s battery life improves.
It’s not necessary to close all of the apps as iOS manages their power usage.
