Power drains are mostly cause by applications running on the background and also wi-fi and other processes that drain power like screen brightness. To reduce all these you can search for an app to help you optimise your power.

You actually powered down last night, or just shut off the screen?

It'd help to see battery stats. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
