Mine isn't any slower than the previous build after using it for a while, and comparing the Antutu benchmark, but battery life is still pretty terrible. I haven't used it long enough yet to know if its exactly the same as the last build, or if its worse.
Compass issue still exists in Maps, but I'm still 99% sure that is a Google issue since clearing app data fixes it every time, and at this point I just assume that Google Backup will disable itself after a reboot as it has never worked properly for me on the F3 on any of the .EU builds over the past year. I'd say more or less this version is exactly the same as last weeks. Xiaomi probably isn't bothering to make any significant changes anymore with the discontinuation of weeklies being imminent for this device.
