Hello, my dad recently lost his phone so we bought an iPhone from our neighbors. My dad doesnt have a data plan so they charge us insane amounts. We called the phone company and they put a data block on his account. Now his iPhone is an ipod touch, with gps and phone capabilities just like he wanted in the first place, only problem is that the iPhones battery drains within a few hours for some reason. He leaves it to charge over night, when he gets to work its already almost dead. My theory is that the iPhone attempts to connect to the internet for updates and data, and when it is unable it attempts to reconnect over and over again in the background using a huge amount of his battery life. Is there any way to make the iphone not request updates, etc and just run as a normal phone?
