Let's talk about battery backup on op5 after update to 4.5.5..
I got very good battery backup after the update..
I got 1day 4hrs...
Try hard reset
No idea about it
Op5 us pretty fast and Mi6 is slow and it doesn't support Volte.

May be u have on the battery savings mode enabled..
That's the last reason..
