Most influence on energy consumption comes from the ability to switch the parts of your device in low energy mode, that are currently not used..
I think the gap between your and my experience may come from battery consumption of your other apps and configuration.
I have very few apps installed, a recently installed system that cares for privacy (also meaning few energy consuming tasks to tell anybody where and when I’m doing what) and while configuring I consequently care for battery consumption. Together this makes my phone to consume few energy - I guess this saves about 10-20% of ‘normal’ battery draining.
For example CoMaps works all offline, including speech output with SherpaTTS and my mail and IM apps check their connections not so often as other apps do. So the modems of my phone may stay in low power mode more time.
Check for switching off unused devices off (NFC, WLAN, BT, …). There may be system options to switch them off automatically when not used for awhile and there are apps that do this, when no system option is available.
Look for apps you don’t need (any more) and try disabling or uninstall (all of) them.
Check the energy related options (adjusting display timeouts and frequency of connection checks or data polling, etc.) in the settings of your system and your apps.
Try to use the low energy switch of your system and maybe of your navigation app if it has such.
… or use software that has more switches for that stuff. 
Anyhow: Enjoy !
