Earlier I downloaded and updated to TD by mistake. To flash back to WCDMA is basically using the same method as I did updating TD firmware. I go into recovery mode and update from SDCard. :)
Start my morning at around 8am and until at night around 8pm = battery level at 60+%. During the day; did emails, surf web, music, etc (not heavy tho) .. to me xiaomi note battery life is good. Dont think it will last 2 days.
