Here is what I've got - stock but debloated KJ6, stock kernel, 1650mAh battery.
From 100% of charge down to 30% in 2 days and 4 hours. Average usage:
Screen time - 2:35 hours (internet, market, SMS, upload/download on WiFi and 4G)
Audio books - 3:14 hours (commute time)
Voice calls - about 20 min. (just like it said)
I did some experiments earlier and can get screen time up to 8 hours BUT when I'm reading books (4G, WiFi off and white characters on black background).
Or stand-by/idle time up to 7 days (in good reception zone with everything off but GSM voice)
