I love MIUI but was very dissapointed when the S4 mini ROMS (MIUI6_5.5..29v2_Multi - KK.4.4.4 and Unoficial MIUIv5 KitKat 4.8.24 from s4 mini (i9190/i9195) left me with a battery drain of 10% per hour.
I know that most people here seem to be running fine on this ROM, but maybe this can help someone who encounters similar problems. I have the I9195 black edition euro, and after fiddling around for days I am now at ~2% battery drain per hour.
Always on LTE heavy bandwith usage (bright green in battery manager)
Had to set up a custom battery usage profile with the switch 2G/3G on. (Power->Power Settings->Profiles)
This didn't really made the system switch between networks, but it changed it to LTE low bandwith usage (olive green)
Smart Network is a feature rich tool to setup connectivity profiles for screen off and on.
IMO better than Intelli3G. With screen off 2G I connect to EDGE, which still provides minimal data for checking IMAP or whatsapp.
Google Services battery drain
I prefer Disable Service, since it shows which processes are active (blue) and can sort them according to CPU time.
There are different guides and lists on the web what services are safe to disable.
Make a backup in CWM, then go to battery usage and look what consumes battery.
Consult lists and use Disable Services to stop the processes.
Delete MIUI apps
System App Remover is your friend. You might have to stop the process first in order to be able to uninstall the app.
There are bloatware lists and system apps which are safe to remove. It depends on what features you want to use.
In my case "backup", "blocklist" and "assistant" were often running.
Battery Guides
Here is another useful guide. There are more topics like kernels with different governors or even undervolting, but I think these will have a minor impact on battery life.
Greenify
Didn't work for me. For 3€ you can use the experimental features of this app to freeze system apps, but I was more sucsessful in optimizing manual.
I want to thank all the people who put their effort into ROM development or creating useful guides.
Peace out.
