I use a Mi3W, miui v.6 release 5.2.27. Since previous version I experience heavy battery drain. I did wipe cache a few times but no changes. I enclose a snapshot of battery consumption

Same to me. Music player is working just for a short time than phone reboots. Tried with google music player as default but no big change.
An other issue is with option menus in some applications like clock: text is white with white background.
