Hmm, so there are multiple having Battery issues, but I guess you have no clue why @The Marionette . For me, I first thought I solved it, because my Phone was suddenly staying at 4% for quite a while, and I tried to drain it by having on the Camera Flash constantly, took about 1 hour to drain it. So my thought then was that the Battery wasn't calibrated after installing the new ROM, but that wasn't the case. I completely drained the Battery to 0% (the rest in Recovery because the Phone shutdown at 3%), and then charged it to 100% in Bootloader. But the issue still persists, my Phone drains it's Battery waaaaaaay too fast, and TurboCharge as you say, also doesn't work. I know it should increase the Current gradually to protect the Battery, but it charges much slower than TurboCharge would have charged my Phone (and it also doesn't display the "TurboCharger Connected" message). I am not sure if logcat can provide you with any information about the Battery issues, but there are clearly multiple people having this issue, and I am not using any Custom Kernel at all.
EDIT: I can try using Kernel Adiutor to check if Deep Sleep has been used.
EDIT 2: Kernel Adiutor says that "Unused Frequencies: Deep Sleep", so that means that the Phone never goes into Deep Sleep at all for some reason.
