Miui 9 vs Miui 10 Backup Battery

[marc_alv]

Hello,

I'm currently in global stable 9.5.19.0 and I'm planning to flash a Xiaomi.eu Rom.
In terms of battery backup is better to flash the latest stable (xiaomi.eu_multi_HMNote5Pro_V9.5.14.0.OEICNFA_v9-8.1.zip) or the latest weekly of Miui 10?

Thanks in advice

If you install an older version rather than the one you have you will get your phone bricked.
