Can you teardown XS and XS Max battery(pcb part only) too ? I really wonder how apple handles dual cell battery pack. As far as i know dual cell will have dual resistance profile so you cant handle it with single Fuel Gauge. According to XRay there seems 3 wlcsp chips. So maybe 2 piece fuel gauge and 1 controller to merge cell states (voltage , remaining capacity etc.) to single I2C or HDQ line. I really wonder this
