My bangle ran out of battery and I used the chance to get some more info on the charging.
Green is the current drawn during charging at 5.1V, blue is mAh as counted by my usb measurement gadget with the dotted part being guessed from time and current because it stops counting below 50mA. Red is a guesstimate of mAh ending up in the battery using 3.8V and 90% charging circuit efficiency.
I guess towards the end most of the "charging" current went into producing heat so red and blue probably could taper of a bit earlier.
Actual gross capacity should be 200mAh, so getting roundabout 170mAh in there is not bad. There is probably some unused capacity left after turning off, even if the electronics can not work anymore.
