Question: In your recent review of the new iPhone 3G, you mentioned that it had weaker battery life between charges than the original iPhone, but that you learned various techniques to minimize this problem. Can you elaborate? Answer: The biggest battery drain is the fast, but power-hungry, 3G cellular network, which lessens battery life on all phones. So, when you are able to use WiFi instead for data, you can turn off 3G reception using a setting Apple provides. You will still be able to make and receive voice calls over older networks that won’t drain the battery as fast.
