Struggling with this board that was very clean.
The S5 rails are jumping up and down from 50% to 100%.
PPBUS_G3H 13v steady
Charger 20v 0.01A
PP5V_S5 jumping 2.5v-5v
PP3V3_S5 jumping 1.5v-3.3v
PP3V3_G3H 3.4v
P3V3S5_EN pulsing 0 - 3.3v
PP3v3_S5 diode mode around 18K.
PMIC_EN_P3V3S5 pulsing
U7650 replaced - still pulsing
U1900 replaced - still pulsing
It doesn't appear to charge the battery either, but the cell voltage was really low.
