My iPhone 4s is my first iPhone, and I really enjoy using it, but I was severely dissapointed when I discovered this major battery-usage flaw. Using wifi drains the battery incredibly fast. If wifi is left on, it will drain the battery (just on standby) within a day. Once I switched off wifi, it lasted over 5 days on standby. Do they know why wifi drains the battery like this, even when just on standby? Can this be corrected? I figured they would have fixed something like this by now if they could; I'm concerned it is a hardware problem that can't be addressed.

    A simple search of the forums will reveal hundreds if not thousands of postings about battery "issues".

    Try a search and some of the troubleshooting that it reveals.

     

     

    Frankly, a full day on a single charge is considered "normal" for smart phones.  It simply will not last multiple days with all features turned on, this isn't an iPhone issue, but a smart phone issue.

    No design flaw.

    When Wi-Fi is enabled, it is constantly searching for a Wi-Fi network to connect to or connected to a Wi-Fi hot spot.  You've enabled a second radio by having antenna turned on.

     

    It makes perfect logical sense.

    If the Wi-Fi is not on, how would it know that it's in range of the network?
