Only partially correct.True, Betas tend to be battery users. Its expected. And Apple tends to fix these issues before GM.However for those who care, finding things that can improve battery life during the test phases (which tend to last a number of months) is a good thing. If you carry a test device and it runs dry early, testing (and whatever evaulation you might need) stops. Tips for beta battery life can quite effective at times.Its also the case that Apple folks monitor these forums, and may see info that gives them more insight on how to improve both the betas and upcoming GM. Like every other software firm since the start of time, Apple makes mistakes. A major reason for beta testing is gaining insight from the results of the thousands of testers that run the code thorugh countless situations they never find.
