Perhaps you can trace it and use a reference schematic from the datasheet of the charger IC.
Which charger IC is onboard? Share the topside markings.Comment

It's most likely a capacitor between B+ and GND, possibly with same specs as the "neighbour". However a missing cap there would not prevent the board from turning on. Its purpuse is just to flatten the voltage. So it would be helpful when you finally share what's really going on with the device, with full history and all important observations stated.
To rely on the cap only is for sure not the right approach here.Comment
