New [Mi4C][MIUI 10 v8.7.19] Phone turn off randomly

[raul1ro]

Today I upgraded my Mi4c from MIUI 9 to MIUI 10 and it start to turn off (only when use it) randomly, even at over 90% battery. After it turns off I can open it only if plug in for charging. And after start, the battery is not low, it is at same level like before turns off.
Sometime when turn off, it is lukewarm and in the rest is cold, but never hot.
What could be and how can be solved? Exists some log viewer to find cause?
