Rapid discharge can be caused by a faulty Tristar IC. Otherwise, you may have a modular component that is drawing excess current. The phone won’t normally get abnormally warm/hot even if it is. If you turn brightness on at full, set the Auto-Lock to never, close all the apps but leave the radios on, the phone should last around 4-5 hours. If you’re not getting that, then consider using only the screen and battery and test it that way. That eliminates most of the modular components. Then try it with a known good screen if it stills drains quickly. In the end, you will be left with only the logic board as the culprit.
