i'm looking at the schematics and it seems to me that both VCC_SYSIN and VCC_BAT+ are connected at the output of the BQ24171, VCC_SYSIN is used by the RK808-D and so on for powering a lot of the components and SoC parts. I guess that it can't charge the battery and power the Soc@Fullpower without overheating, i'm sure i placed some thermalpads between the IC and the metal "shield" around the SoC, but none between shield and backcover, with a 90%+ efficiency and around 11W output it should dissipate slightly over 1W @full load, weird that it seems to require this much cooling
