So I've been using the Mi4 for a few months now and in general I am very satisfied with everything. I am running Xiaomi.eu rom as with the default ROM I could only get 2g in Finland. This relates to my fist issue. I live in Estonia right now (though I use Finnish sim-card) and I noticed immideatly after moving that my battery went from approx 60 % to 1 % overnight! Now I have to turn mobile data off each night to prevent this. It doesn't matter whether I have any apps running or not, something weird is going on. It's not such a big deal as I am now used to turning it off while setting alarm, but still.. Another perhaps more annoying thing. I can't find in the settings where to control the screenshut timer. (Screen dims way too fast!) Just brightness I can control. Thanks guys!
