Is overclocking your Android phone worth it?

Many, many people ask me if I overclock my phone. In short, the answer is no. I overclock my devices for testing purposes only. For daily use, I usually keep my phone at the stock clock speed. Sometimes I will even underclock my phone. You might be asking, why is this? The main reason is battery life. Overclocking will, of course, make battery life worse. While I have used many Android devices, I don't find overclocking to improve performance enough for me to sacrifice the battery life for it. When I say performance, I don't mean benchmark performance. I am referring to real world performance when I say "performance." Benchmarks is a whole different topic I will address soon :)

My ideal phone can go an entire day without needing to be charged (from when I wake up until I go to sleep). Later Android devices, such as the Samsung Epic Touch 4G has been getting significantly better battery life than the original Samsung Epic. This brings me hope! Don't get me wrong, I would love to overclock my device. With current battery life as it is though, overclocking is out of the question.

Let me know what you guys think! Do you overclock your cpu? Do you think sacrificing battery life is worth it? Which CPU software overclocking do you use?
