How I solved my battery solution: restore as a new phone from iTunes then Erase All Content & Settings from the iPhone (Settings > General > Reset). I don't know if the erase actually fixed my problem but I believe it did. I still didn't install any apps because I'm too scared of putting my phone in my Mac and the battery drainage returns after the sync and because my credit card doesn't work. I also don't have all my contacts and none of my music and videos. I fear the battery drainage is going to come back! I am now on 2 days, 4 hours standby and 2 hours, 35 minutes usage with 31% battery. I received and sent about 5 texts and had a total call time of 15 minutes (estimated). Maybe 25-30 minutes of 3G and 20 minutes on WiFi with Safari. Looking very good.
Try restoring the iPhone as a new phone [and erase all content and settings (I don't know if this actually works but as long as you restore your iPhone, its okay to try this). I suggest you install all your contacts, music, and videos before you take your iPhone from your laptop. Don't put any apps directly from iTunes but use the app store from your iPhone to get the latest version and avoid issues. I'm not sure if the problem will reappear after backing up on the laptop.
Hope this helps and please report back if you do what I mentioned above.

I have let the battery run right down now and its gone off so charing on my PC now. When i spoke to Apple spupport they said because its happened the same on both new phones, they think its either extremely bad luck! or that there is an app on my phone with a virus etc causing the problem. I have taken nearly all my app's off, i only have facebook, twitter, sky+, starbucks and few games for myd daughter now and it still has the battery issue. I have turned Siri off now as well as i dont use it and thought i woudl try that as the battery issue only started after about 4 days of having the phone and i think my other half turned on siri for me after the first couple of days.
I will see what happens with this charge, it will sometimes say 100%, and then as soon as i plug it out, it drops to 97 or wont charge up to 100. I dont have push notifications on for email etc. I am a bit annoyed as i dont see why you should have to turn certain things off to get a better service from the battery, isn't that the whole point of an iphone!
