Go to Settings/Battery and see what apps are using energy in background. You can also go to Settings/General/Background App Refresh and choose which (if any) apps you want to allow to run in background.
The best answer, however, is to plug the phone in overnight, every night. In addition to eliminating any concern about energy used overnight it has other benefits:
- Any data used overnight will use WiFi rather than cellular; WiFi is turned off when the phone is on standby to save the battery, unless the phone is plugged in.
- If you enable automatic backup to iTunes or iCloud the phone will create a backup when the phone is asleep, connected to power and connected to WiFi.
- Your phone will be fully charged at the start of every day.
