Iphone 4 battery life dropping dramatically?

I bought a iphone 4 of ebay in october last year. When the phone came it was faulty but i did know this as i the seller described that it was faulty. I bought a new speaker for the phone as it sounded distorted and you couldnt hear it when it was at full volume. The new speaker i fitted worked and i could hear the iphone with ot it sounding distorted. Since i put in the speaker the iphone has lost battery life during the day. When i'm at work it is at 50% by 1:00PM. I turn all the brightness down close all my apps Wi-Fi is always off. I don't understand why it is losing battery life so quickly all i did was replace the speaker.
