You can use www.ti.com/.../bq24780s.pdf figure 5 as reference to estimate bq24725A efficiency curve.

Hi Wang

Thank you for your reply.

Regarding to efficiency vs charge current for 1-cell, we want to estimate efficiency during charging like following figure.

Is it reasonable to refer figure 3 of datasheet of bq24780S? (VIN condition is different though)

Or can you offer any other material to be referred to?

Bestregards

I don't have any other material for bq25725A 1s efficiency.
bq24780S datasheet figure 3 is 12 Vin; figure 5 is 20Vin.
