1. When I type, if any wrong term gets typed, then iPhone suggests with voice the correct one. IT happened on my iPhone 4, but it doesnt happen on my new iPhone 4S. What is missing ? 2. The battery of iPhone 4S looks very weak. I have to charge it 2 times in a day, even if I dont have any apps running except facebook and mail. Why is that ? 3. While charging , the backside is getting too hot. Why ?
