Miui 9.1.24 not optimized


Mar 23, 2016
Hi ! I have just flash this rom xiaomi eu on dev 9.1.24 on my mi 8 global version.
I comes from global version and this rom are more good because gheh had Android features not present on global rom.
But the autonomy are more good on global than xiaomi eu perhaps do make configuration for have better autonomy and stay 3 days for Rom are more stable.
I have a question about "no optimized"
I see on Android setting a lot of App are not optimized ? (Photo)
How can optimiz it ? Or can optimiz all ?
And if the stable version of xiaomi eu had more good autonomy than Dev Rom ? Thanks for help I like so much this Rom very good work.
