If you can not replace it yourself- you can buy repair service from my shop.

Please note- originally it was 0.25 or 0.5W speaker. 

I do sell 0.5W. Wattage means- maximum power spekaer can achieve and how durable speaker membrane is.

So - it does not affecet battery usage at all. It consumes the same amount of current and sound the same like original one. But

It is better quality than original one.
