Thanks for responding, I have used the tips in the battery saving thread,such as the juice defender plus and app killer, as well as turning brightness down, however some tips make it pointless having a smart phone. I really am not using my phone anywhere near as much as I did with my iphone but the battery is just shocking. However, when I removed the sim card to use it in another phone, I fully charged my Incredible S and just had it running on the wifi, sim free, the battery was amazing and still almost full at 6pm, when usually it would be telling me to plug it into a charger, or would have died by this time. This was with my usual syncing and push notifications. So it makes me think that it is the signal issue which is causing this.
I have a feeling it may be to do with when my number was ported over from o2 there were some issues. I am going to try it with another talkmobile sim on a different number, and see how it gets on. It may be switching numbers may be the answer but I really cannot see how.
I have seen maybe 3-4 people on this forum with the same problem, so maybe it is a handset problem. I'm not one for being picky usually, but it's a lot of money to spend over 24 months on something i cannot even do basic phone calls on. I just end up missing half the conversation because it keeps cutting out, or it just ends the call completely.
Anyway rant over, think i've just got unlucky, my boyfriend has the desire on 3, and it works perfectly, which is why I wanted to go HTC next, I was really looking forward to getting the phone which makes it more irritating that it doesn't work. Oh well hopefully it will be sorted in the end.
I will take your advise though and call HTC, as at the moment I have just been going through Talk Mobile/Carphone Warehouse customer services.
Thanks again for responding.
