My other storage after updating one ui 6 is 14.6gb and system file storage is 13.5gbI checked everything. Kindly guide how to reduceother storage.I'm talking about other storage not system file storage.

My other files storage is 13.5gb after update and system file is 13.6 gb.What is other files. Why so much storage taken.

Screen on time missing from last charge. Its showing SOT day basis. But earlier it was showing screen on time from last fully charged. In this way i could have understood how much battery backup I'm getting.
