Correct charging current for lithium-ion batteries
Replacing a LiPo battery with bigger capacity is okay, since the device''s charger likely would not know this, and will charge the battery with old current, which would be below the "safe charging limit", typically 0.5C as bitsmack already explained.
Differential current in constant-voltage charging mode: A novel …
It can be observed that under the same cut-off current of 0.05C, the CV charging time increases from 3250 s to 3750 s as the number of cycle increases. In other words, an older battery will take more time to complete CV charging. This indicates that current at the CV charging stage has a strong relationship with battery SOH.

batteries
Introduction. Various resources state that the optimal method of charging a li-ion cell -- such as one found in a mobile phone -- is to charge at a constant current (usually <1C) until a certain voltage threshold is reached, then switch to charging at a constant voltage until the charging current drops to about 0.1C, at which point the battery is fully charged.
