About automatic executiation of possible power hunger apps

[hajime]

Hello, some apps such as Facebook, LINE, Youtube, Instagram, WeChat, Flipboard, QQ, Dropbox, Word, Excel, PowerPoint require the user to log on with an email account. Are these apps automatically executed whenever I turn on/restart the iPhone 6s plus? How can I tell? Do they consume a fair amount of power? Is it a good idea to prevent automatic execution of these apps to save power? If so, how to do it? Thanks.

Apps are running when you open them. After a reboot no third party apps are loaded/running, so there really isn't any automatic execution of apps.
