Similar battery issues here also. For the first two months with the phone, I had no problem with battery life. I've done all the battery saving techniques decribed above and that seem to work fine. However, the last two days my battery had been at 10% by lunch instead of being at 50% still at the end of the day.

I've added nothing to the phone in terms of programs since the first couple of weeks I got the phone. I'm beginning to wonder if the phone may be searching for singal more for some reason all of a sudden. My office is the same so I'm just not sure what has changed. Very odd.

I'm thinking of getting a charger for the office. I assume they can be had for a good price at Ebay, but if anyone else has any suggestions, I'd be interested in hearing them. Again, it seems like in the last two days, my battery life has become non-existent.
