Can someone help me with this below post? I'm having awful battery life with this phone and I'm all out of options. This post below was from a guy describing how he saves battery life. I followed what he did, downloaded Set CPU and copied the settings he had but my question is how do I make my screens black? Do I need another program or something to do that? I'm running 2.1 DD10 rooted. "i got 12+ hours and still have 15% left, but look at what I had active. I have two twitter clients, active push email, multiple calls, and email usage over the day. I get a new email on average every 5 min. I also have Gtalk, and Gvoice. I have livewall papers, star field. I had background data on , GPS on and WiFi on all day. I use Handcent a bunch, and nubinews is active. I didn't open and kill any tasks with ATK after the morning. I have set the background to mostly black, you will save 40-60% of the battery life with black and loose 300-400% with white. EVERY THING should be black if you want to save battery life. I have the MAX CPU set to 266 after 50%, and max of 60MHz while idle (basically screen blank). I have the governor set to conservative. I allow up to 800MHz above 50% but I have it set to conservative. considering the work load I put this thing into, this is the best performance I have ever gotten. I did this using calken latest, with root and setCPU from SetCPU for Root Users [1.5.1a] 04/02/2010 - xda-developers I think you can get good battery life if you don't load everything onto the phone, and make some smart choice."
