Quite impossible to tell. For starters, it depends *heavily* on what
phone that is. Somewhere in the chain between the mains power and the
accumulator cells, there *must* be an accumulator charge/discharge
control circuit. As long as you don't reveal the model of that phone,
it's anyone's guess where that circuit might be. It could be in the
battery itself, or in the phone, or (possible, but much less likely)
it could even be in the charger.

You'll most likely find that the number of terminals on the battery
isn't even the same as the number of pins on the charger's connector,
and that's before we start considering unknown polarities and
pin-to-pin mappings.


It is worse than that. If the battery is charged at to high a voltage it can fail or catch on fire. It depends on where the charge controller is. Li-Ion are not toys. Find a different phone. Or use a voltage regulated current limited power supply.
