I think battery charging *never* may be turned off. There is no valid reason to do this. Set max bat-voltage correctly and let PCF50633 handle the end of charging. Instead reset max USB-current to 100mA and *enable* charging on every occasion (u-boot, power-interrupts, just *every* occasion) if there's not wallcharger detected or 500mA negotiated actually. /jOERG
