Ok I figured out a fix for this by browsing other forums. I just turned off the amber alerts in cell broadcasts. This fixed it for about 1-2 weeks and I literally only had a drain of 5% drain overnight(10-11 hours). Now, it's back up again. the msm_hsic_host is taking up a lot of battery and my phone goes into 0% deep sleep during the night.... What is causing this randomly??!
