battery drain and poor network

[CYLim]

Hi.. Im CYLim . Im using note 10 plus for a month , im facing battery drain problem and poor network issue .

1. I went to sleep with my network data is on , after 7 hours my battery dropped 30% . 

2. My signal bar is only 1 while my A50 is 4..

Did anyone of you encountered the same issue ? Can give me any suggestion..

Thank you..
