![]() Since I only downgraded today, I have to test for some time before I can declare the problem fixed. So, I believe this may have solved the battery longevity problems. When I wake the machine from standby, coconut battery shows 0.1 watt consumption. Here's what to do if yours isn't meeting those expectations. And the battery life on video calls will be twice the rate on current MacBook Air computers. For video playback, the battery will last 18 hours. Power consumption in coconut battery shows 5 watts at idle with no applications. Apple estimates that its latest MacBook Air should get up to 18 hours of battery life depending on how you use it. Apple on Tuesday said that its new MacBook Air will have 15 hours of battery life for wireless web browsing. So, I downgraded to Snow Leopard by reinstalling the machine from scratch. My MBP (mid-2010 13" 8GB Snow Leopard 10.6.8) only consumes 9 watts at idle on battery by comparison (and it doesn't have SSD and other power saving features available on the MBA). On charge, it showed 434 watts (shocking don't know if this is normal for Snow Leopard though). The case was also uncomfortably warm when operating on battery. I ran Coconut batttery to discover that, at idle with no applications running in the foreground, the machine was drawing 16.7 watts. After the Lion upgrade, immediately useful battery life was 2 hours and standby barely lasted overnight. Prior to the Lion upgrade, useful operating time were 5+ hours and standby forever it seemed. My wife's MBA (Late-2010 11" 2GB) had its standby and operating times destroyed by Lion. ![]()
