    I have battery drain issues while I'm at work. The 4 sits on my desk, minimal use (checking for emails...I miss the notification light on my old BB).
    Wifi and Bluetooth shut off, mo apps running in the background, and I'll loose 35-40 percent of my battery.

    We have signal repeaters installed throughout the building and I never have less than 4 bars of signal strength.

    My question is...do I have issues with my battery or is this normal?

    First iPhone, coming from over a decade with BlackBerry.

    my iphone 4 will lose about 10-20% battery without running any program or accepting email. but i charge it everyday coz in day time i love play my phone a lot. about the battery losing, it also depends on how long you slept. you longer you slept, the battery losing is higher. lol.
