"It's because Li-on batteries break if they get down to 0%. HTC set their phones up to shut down between 10-15%. All phones with li-on do this.
However most phones show that 10-15% as 0% but HTC tend not to.
There is an app called nexus one battery calibrator, which if you have the correct kernel, will change that 10-15% to show as 0%. Obviously, as it effectively turns 75% into 100%, it appears to drain faster. It's not
I don't know if your kernel supports this. The general tab in the app won't have any numbers if the kernel does not.
There are some complex settings needed in the app and a specific process to follow if you wanted to do this though"
