Three weeks ago, my wife finally received approval to upgrade her 2-years old Blackberry to iPhone 5. Things went smooth but she noticed, over a period of next four days, that her iPhone 5 would run out of battery in the middle of the day and it was fully charged the morning. My iPhone 5 battery always above 60% at the end of my workday. She even thought she got a lemon iPhone 5. I played with her iPhone 5 settings and took a couple days to identify that the notification and particularly Calendar syncs were the main culprits. Because the mobile phone is paid by her company, she has to keep the Calendar sync functionality enabled as it has an useful alert mechanism also. Turning off the Calendar sync was not really a solution.

What is even better is that Amazon and Trent offers iTorch (another +20 hours) battery for free if purchasing Trent iCarrier. Now she could even watch a movie with her iPad3 if she wants while waiting at the China airport. Price would be total $80 including tax and using the free standard 9-day shipping. Whether her company would re-imburse the purchase is not an issue to me. luoqiyin666
I paid the extra $25 one-day shipping because of the urgency. The shipping actually came two days later, right, two hours right before my wife departed for the airport. I called Amazon to explain my disappointment, and were refunded with $25 quickly.
