Cell Standby Battery Draining Issue

[AC Question]

I have enjoyed my Galaxy s6 for months now, but up until a couple days ago my battery is draining fast when idle. i had about a 60% charge when i went to sleep and woke up to 12%. i've never had this issue before. "Cell Standby" seems to be the culprit of my battery usage. I've never had this issue until recently. I've cleared the cache, but doesn't seem to be working. Are there any other tips/apps that are helpful?

Are you experiencing problems with the cell signal? A weak signal could drain your battery specialty if you leave mobile data on. Or maybe it could be some problem with the SIM card.
