It is possible for the battery voltage to dip to 1.8 VDC due to the Powerboost and the lack of a battery protection circuit. With this low of a voltage, the charging current becomes very low (~78 mA). Once the battery voltage raises above a threshold (~3 VDC), the charging current increases drastically (~500 mA).
