I've used the weekly updates of MIUI V6 on my Redmi 1S WCDMA for several weeks now. I came from MIUI V5 v50 and updated fom SD-card using TWRP 188.8.131.52. If did a factory reset to get a fresh start. My biggest problems until now are: Freezes of up to 20 seconds (Facebook, aCalendar, Candy Crush Soda, CM Browser, etc.) Even unable to answer calls, but I can here it ringing!! Sudden battery drain (which seems to be related to the freezes). Sometimes I have over 10% left and within minutes it's empty. Heating issues during the "freezes". Backside gets really warm/hot. Seems simular to the issue while I used MIUI V5!! Questions: How are the experiences of other users with the same phone? Does anybody have a "snappy" version running? Any suggestions on what to do? Already did a factory reset (again) and cleared cache/dalvik after each update. I love the new changes in V6 (lockscreen notifications, better battery life if no drain), but this is not how it should be. I hope someone from the devs can look into this or at least respond to the issues.
