I have an iPhone 3gs 32gb. As they do, my battery was noticeably depleting as well as conflicted with the device having been slightly water damaged (dropped in quickly but immediately turned off and dried out. Works "fine"). I decided to replace the internal battery with a factory OEM version but even after doing so my battery life is awful. I am talking about losing 10% during one 4 minute phone call or 30% in the first hour or less or simple standby.
Are there things I should look for or perhaps additional parts which could be causing the depletion?
For reference: I charged the phone to 100%, turned the phone off, then 3 days later (with phone off) the battery was completely dead. Something else seems to be constantly running or draining the battery.
