I have had so-so battery life with my new iPhone 4, similar to many others. I have been trying to dig into the issue within my settings. I have noticed that when i am not at either car (two cars each have an automatic connection to my BT), and when I do not have my BT earpiece turned on, my iPhone has a spinning gear in the Settings>General>Bluetooth window (each of the devices is listed, with 'Not Connected'). So I have a few questions for the resident macrumors mavens (MacRavens...?): 1. Is this 'searching' normal? 2. Should I always turn on my BT earpiece so the iPhone stops searching? 3. Does this searching use up much battery by itself, especially compared to the energy lost in using the earpiece? 4. Does the earpiece use up much battery if I am not talking on it? In other words, do I gain an advantage by leaving the BT earpiece connected to stop the searching, even though I don't use the phone/earpiece more than an hour and a half to two hours each day? 5. Would this searching for a device stop if I reset all settings? How about if I delete each BT item and reinstall each? Do I need to do a 'nuclear' restore to new? Thanks in advance!
