Q: How can I improve my battery life?
First off, you should read this post: Battery Life on G2X
You do not have to follow all of the tips/suggestions, but the advice is sound and will help. Smartphones operate on a sort of spectrum. On one end you could put battery life, on the other end all those options like wifi/3g/sync (among other things). If you want great battery life you can't have those on all the time. If you want those on all the time, you won't get great battery life. It is best to find the compromise that works best for you and what you want most out of your phone.
