I just bought an i5 2 days ago. I don't know why people are saying the battery life has been worse than past models. On my 4S, I would end up having to charge it throughout the day. I would probably end up around 10-30% left at night. I woke up at 7AM today. I've been using my 5 nonstop. Texting mostly. And trust me, if you have a GF, you will send texts and talk on your phone through the day. Right now, around 830PM. The iPhone is at 73%. All of my settings are the same. Nothing has changed. And yes, I've had LTE on. And btw, the phone is amazing. Weight, size, battery life as I mentioned, quick. Very happy.
