I've been using CM7 for a few weeks now, and have been loving every part of it, except the battery life. If I don't use it at all, or very minimally, it'll last just under a day. Moderate to heavy use will only get me 8-12 hours, tops. I came from Liberty GB, which I could get over a day with moderate use. I know there are many tweaks I can make, but I don't know what each of them does, or how they impact battery life. Any tips on what settings I can change to get a little more longevity would be helpful. Thanks in advance.
