Battery Drains standby 2 hours Help

I need help guys. My standby drain has become worse. I took my phone off the charger after doing a battery calibration (let battery die and recharge without turning it on) and clearing cache and battery info in TWRP. I noticed three hours later that my battery was down to 95%. This is in standby. WiFi on. No Bluetooth. No location services. And greenify.

I am currently running PA 5.1.1 with the kernel that come with it. However, I did notice worse battery life when I was running Stock Oxygen with Boeffla kernel. Most days I cannot surpass 3hr SOT. Back in November I was easily hitting 4.5 hrs SOT.

Please help. Screenshots attached.
