Apple claim that it will last almost 2 weeks on standby, but from my experience of 3 different iPhones that is just a ridiculous exaggeration. Maybe if you disabled GSM/WiFi/Bluetooth it might last quite a long time, and turned the screen way down, and didn't use it at all, but realistically iPhones get 1-2 days max, even with minimal usage. I'd agree with you; look elsewhere if you need something with a good battery life. 🙂 Preferably a non-smartphone, as none of them seem that great with battery life.
