I just posted this over at XDA but I'll share my glory here as well. I'll provide a detailed account of what my usage was like. I consider this light to moderate usage as I didn't do any huge downloads, no video or picture taking, and barely played any games.
I charged my phone to 100% at about 3:00pm yesterday and have been using it until 8:40am this morning. I read a lot of manga on it for about 4.5 hours collectively and did some web browsing for a while and pinning stuff in Pinterest. Most of the time on WiFi and updated about 6 apps through the Play store. I also ran an Antutu benchmark late in the night which scored 39,075 (not bad). Then it sat overnight for 6.5 hours losing about 2%. In the morning I opened a few games up to get daily rewards (20 minutes of time) and watched a full-screen YouTube video on mute for about 15 minutes.
A majority of the time my phone's brightness was anywhere to 35-45% brightness managed by Lux. For about 45 minutes it was on very low brightness while reading manga in bed (like -35% according to Lux). It's my night mode and it works very well when you are in a pitch black room reading a black and white comic.
During all of this I texted my wife some (15 texts?) will full volume short ringtone and vibration on and took two short calls under 3 minutes each with moderate earpiece volume. No speakerphone.
