i found a temporary solution. U1 8leg IC got heat that time vbat led not working. for experiment i change same kind of IC from UFS. but when i connected with out cover and screw box is ok vbat voltage 4.1v. with cover and screw no vbat voltage and IC also got heat like before. now i use with cover and without screw now vbat ok . i think when put screw vbat grounded. plss look that subject cylocne team thank you
