New Bad Battery Information On Leo With Last Update.

Sep 1, 2014
Since the last update in Mi Note Pro (Leo), the battery % is not ok. My phone turned off right now with 6-7% battery. Then, I plugged the charger in, and it the big battery icon that appears when your're charging the phone if turned off, told me that battery was at 0%. About 40 seconds later, it was at 30% (impossible to charge so much in 40 seconds), and now it seems after that "sudden" 30%, it's charging well (charging about 1% per minute more or less)
That didn't happen with previous roms, so please look for a possible bug in battery management. Thanks!
