Need some help here... flashed Cm7 to hubby's Evo and he loves the look and feel of it... however, battery life is TERRIBLE for him. He's burning through an extended battery in 6 hours. Any ideas? Is there is a kernel that might help improve that? I use CM7 on my Nexus and can last on a full battery for around 10 hours with moderate usage. He barely uses his to text. He works in a warehouse so he doesn't have the time to mess around with it.
