I have deleted 3 or 4 live wallpapers i had downloaded thinking maybe this is drawing power even when they are not being used, but Im still losing about the same
Is 10 - 15% loss of battery overnight (no use of phone) the norm?
Yes, you have to remember this is a smartphone. Meaning you control and allow the phone to do whatever it wants. And you have to be conscious of what apps you download and their permissions.
Sounds like you have downloaded apps that are either staying awake or waking up and using the battery by sending and receiving data. Or some apps can be utilizing location services. That means you need to ensure your radios are off at night or download the apps Gsam Battery Monitor and Wakelock Dector. Those apps will tell you which apps are using up battery and cpu.
For example, I noticed Google Maps wakes up constantly to check it's location for a better user experience. I nipped that in the butt by turning that option off. Google Maps will sleep like a baby now.
