Check what is running in the background and stop or uninstall whatever you are not using or do not want. Check google services. Uninstall every app you have not installed or you are not using. Get rid or block all the bloatware.

You may do a 'factory reset + clear cache partition' after a full data backup. Then just install only apps you actually need recently.
In addition, as @marco sarli said, avoid or stop any bloatware.
