Over the last week or so, my battery life began depleting faster than normal. I thought it was because of my charger cord. When i went to plug my phone into an FM transmitter via the docking (i had used it a couple days before no problem), it reset itself. I turned it on and the battery just kept dying faster and faster. The last time i turned my phone on, a text message came through and my phone just shut off and the screen just faded out as if it had water damage. It's been two days and it hasn't powered back on...Do i just need to replace the battery or did i mess something else up by plugging it into the transmitter? Thanks in advance.
