For me, I'm having 2 days 10 hours and 12% battery remaining.
2hours screen on, MJ7 firmware.
This is only on my first discharge cycle.
Fair amount of using whatsapp, calls and sms and applied all the settings above.
I don't know if this is a good start, but will have to wait for more few cycles.
Notice that the google play services is using too much of wakelocks on my device..
Thinking of removing the google play services updates and needs further tests.
