Some causes of battery draining:
1. If you are using any heavy apps, like playing music for a long time, watching many videos.
2. Keeping too many pictures in the pictures folder.
3. Very Bright screen - Reduce the brightness of your screen by going to Settings -> Display -> Brightness. There, lower it.
4. Syncing everything - phone tries to sync every google account. But it drains the battery very fast, especially, if photos are getting synced. Go to Settings -> Accounts -> See what accounts google is syncing, and decide what you can choose to not sync so regularly.
Besides these, you should uninstall any apps that you are not using. Also, you should not run more apps than you are using.
