A word of comfort first....I once had a phone - not an Android - drain from 100% to 3% overnight....it had powered itself off to protect the battery. Even now I'm not sure why, but at any rate, you're not alone.
Use the phone normally, and before you recharge, take screenshots of the battery usage stats, also the expanded battery graph with mobile signal etc at the bottom, and post them here. Tell us also your screen-on time, typical brightness, and roughly what you used the phone for. Then we'll attempt a diagnosis.
