Hello,

And you are back on xiaomi.eu or you are on stock ROM now?

I have the same issue with battery drain in stand by, and I would like to know if flashing stock and than comming back to xiaomi.eu solves the battery drain issue?

Thanks!

I had the same.. I think problem is in some mistake during installation... Because I have repaired it by flashing official rom and than flashing xiaomi.eu again... And no problem... With the same xiaomi.eu release... So it is not bug in xiaomi.eu

May I ask which version of Mi Flash are you using?
And which fastboot ROM?

I have tried with latest global and global EEA ROMs, and a few versions of the Mi Flash Tool, tried to copy the extracted ROM to C:/ and other folders, but I always get a "flash csclist error" and stuck in fastboot. I can boot to twrp and flashed back xiaomi.eu.
Phone is formated now and before I set it up again I would like to flash the stock ROM...

Thanks in advance for your help.
This battery drain is really annoying...
