Has anyone tried charging with one of the larger iPod video bricks instead of the little one that the phone came with? It looks like its higher Amp and will push the battery to full without my having to turn the wifi off. Auto-Brightness On or Off? I set mine screen on half brightness. I would have thought that autobrightness would hit it harder because the cpu has to process what the lightsensor reads. I do notice that when set at half, when I turn auto off the screen gets brighter. I can solve this by just lowering my brightness setting, but doesn't constantly adjusting the screen via the sensors drain the battery more than just choosing a lower manual brightness Surfing via edge or Surfing via WiFi? Does auto-join mean its constantly searching? I would have thought that setting only applied to hitting the first network. I thought once you were on a wifi network it stopped searching unless you went into settings to choose another. As anal as Apple was with battery life, I can't imagine thay'd allow a hit like that.
