It's been happening for almost a week now and it's really frustrating i leave my phone at 100 percent charge and when i wake up it's either 52 or 67 or 71 and battery life seems poor too
I did some tests ı uninstalled google play services used greenify, used rom's wakelock blocker (checked everything there) enabled power saving mode, undervoltaged, gpu idle speed 27mhz i did a lot of things to save battery before going to bed and the battery was 81 and i just woke up and the battery was 49 percent after using it for 2 minutes it dropped to 43 percent, the phone got a little water damaged 2-3 weeks ago i wonder if that did something should i get a new battery?

I'm rooted, boeffla kernel with resurrection remix rom
SM-900FQ

I checked GSAM battery monitor and the only thing that drains my battery was screen (80 percent) it drained more when it is off than on :D
At the wakelock blocked it says phone deep sleeped for 9 hours 52 minutes and was awake for 5 minutes and 24 seconds
