Phone's battery working in good condition despite swelling on it.

My phone functions so fast despite it's battery swelling up.The phone functions so well including the battery that holds power for a longer time and not experienced any strange behaviour. What can you say concerning that?

Not sure, but if the battery is swelling, it would be best to replace it as soon as possible to prevent it from pushing the screen.
