Not really. The kernel takes battery measurements every 5 seconds, while sleeping or not, and then pipes this data to the daemon which processes the numbers and computes a percentage. The percentage is then sent back to the kernel so it can be presented on the old interface that all htc libhardware's want to use. The measurements have to be fairly often to reduce noise. I really don't see the problem though at 70 hours it is a 10% reduction in life. With more usage, say your only getting 24 hours, its like 3%. At 8 hours its only 1.
