If you look, the 1 and 2 screenshot didn't influence a lot on battery.. It looks high, but if you pay attention, it's draining 0.9%..1% so, not the beest battery life, but "normal". If you pay attention now on "deepsleep" screenshot, you will see that it drained most of the battery during the night.. So, my conclusion? Maybe some problematic gapps , trying to connect to some server to sync even with sync off, try another gapps. Second option : flash another kernel, it could be caused by kernel keeping the phone awake even when it's trying to deepsleep
Edit : almost forgot.. You could try to connect to wifi, and leave the phone for some hours with sync enabled.. It would sync what the phone tries to sync and fails during the night.. Sounds crazy, but solved my problem once!
