I use an Xperia S (sorry, not an iPhone), and I have noted:
1. with Wifi/internet off, I get 3 days battery out of it, with normal call useage and texts.
2. With Wifi/internet on, I get a day if I am lucky
3. If I turn the GPS on, halve the above.
Was fully charged this morning, and I have had the internet and WIFI on all day - it's now at 17% charge.
