You cannot stop apps that want to run all the time - they will just start up again (which probably uses more power than leaving them alone). What you CAN do is not install them in the first place. You need to make a decision of whether you want long battery life or do you want constant immediate arrivals of messages from mail, social sites, etc. It is your choice.
Here's what I do. I leave all of Google's apps/services alone EXCEPT for things they provide settings to turn off.
I turn off these because I don't care if my phone is backed up, contacts synced, gmail received:
Google Sync/Backup, Gmail Sync
(note - if you want to send or receive mail with Gmail APP, you need to turn the Gmail sync back on - but often I just use Chrome at Gmail.com instead)
I turn off these
Haptic feedback, keyboard vibration setting
I turn off ALL connections until I need them
Wifi, Cell data, Bluetooth, GPS, and I set Location services to Battery Saving (or pick off if Battery Saving is not offered)
I do not use live wallpaper or 3rd party launcher - I use dark wallpaper and a low screen brightness setting
I do not install social apps that constantly get messages. I do use a Twitter app that does not seem to wake itself up and only gets messages when I start the app.
Also, if I MYSELF installed an app and I catch it waking up on its own I see it in the Running column of Settings...Apps), I uninstall it and I find a quieter replacement. Kindle Reader kept waking up so I uninstalled and I use Wattpad just to have something to read on my phone. I have a physical ereader (Paperwhite) and don't need my Kindle books on my phone). One navigation package kept waking up so I uninstalled it and am trying another. Etc.
Also, when I charge my phone, when it gets to 100% I turn on Wifi and let it do all of its updates which connected to power. When it is done updating and still 100%, I turn off Wifi and unplug from power.
I am a light phone user (few calls or texts per week, light gaming (not every day) and occasional photo take or show - I get over a week of standby from one charge.
