You are in the minority dude.
Brand new TBolt and I got 3-5 hours. Of STANDBY time.
Could it be bad batteries from HTC? Hmm - they are a cheap Taiwanese company, no?
I am not trying to start a flame war, but you are most likely in the minority. If the majority of people were getting 3 - 5 hours of standby time, the forums would have a lot more complaints. The reviews would also show these figures.
There are a lot of potential causes of bad battery life. Buggy apps, poor signal strength or quality (a major factor), and how you have the phone set up.
I usually have no problems making it through the day, even yesterday when I was in 4G LTE coverage. This is with 3 email accounts and calendar sync enabled. In fact, I really haven't taken any major steps to improve battery life other than disabling sync on the Blockbuster app and installing a newer version from the market.
Battery life on this phone could use some improvement. However, it also isn't anywhere near as bad as some people make it out to be.
As for calling HTC a cheap Taiwanese company, that is a bit disrespectful. They are a global company like almost ever other large company. They may be based in Taiwan but they have several facilities in the US. HTC makes high quality products (they have to due to the amount of competition they have).
Besides, I think most of their batteries use cells from Japan. If you look at the battery, it should list where the cells were made and where it was assembled. The Li-Ion cell could very well be from a comapny like Sony, Panasonic, Sanyo, etc.
And of course, defects are always possible. Nothing is perfect.
