I have just recently moved and noticed that while walking through the house the signal strength on my iPhone changed dramatically and at the end of the day, my cellphone battery was drained (this doesn't usually occur).
Using this tool http://dl.dropboxusercontent.com/u/22487235/Address.html (provided by Geekzone user BarTender), I noticed that there were three Telecom XT cell towers all within equal distance from my location which formed a triangle (if you were to connect the dots) centring on my address. I used an app on a Samsung Galaxy SIII which told me that the phone seemed to jumping between the three different cell sites and when using Google Maps with WiFi and GPS turned off, my location on the map would jump around dramatically as I moved around the house. I also used field test mode on my iPhone 4 to get more specific readings of the signal strength moving around dramatically as I moved throughout the house.
Is this normal and is there something I can do to rectify the problem or am I just unlucky? I understand that all cell sites overlap in terms of their coverage but it seems unusual that my phones would be jumping between different cell sites!
Thanks in advance for any help/advice!
