I've been using the iphones for a while now and I did a battery discharge a week or 2 ago (when the battery is flat let it sit for a day before charging) - what apple recommends anyway. I've noticed that the battery life is shorter with 1.1.4 compared to 1.1.2. I didn't really take note of how many days 1.1.2 lasted but it lasted for just over a week - which is still below what apple has claimed. I don't use my phone in extreme environments so the battery should remain happy. I charge it with about 10% remaining. Here's my daily patterns (on average) of iPhone usage: 3-5 minutes of calling on loudest 10 minutes of wi-fi browsing 1 minute of EDGE browsing 10-15 minutes of music through headphones 1 song played through speakers at half volume screen is on +- 5 minutes of other usages does that seem acceptable to last +-5 days?
