1. Turn off Siri
Imagine it's like a person. If Siri is constantly waiting for you to turn up and say hi, it would probably be quite draining - so if you're not gonna use it, switch it off. To do this, go to Settings > General > Siri.
2. Turn off vibrate
If you check your phone all the time or use the loud option, the chances are the vibrate is pretty useless to you anyway. Go to Settings > Sounds > Switch off Vibrate on Ring/Silent.
