I previously wrote about a usable workaround for the iPod iOS 4.0 battery drain issue. I had high hopes that iOS 4.1 would fix the issue, but no luck. I still have to put the iPod into airplane mode to avoid the battery draining while the iPod sleeps. While it is not an excessive amount of work, it is easy to forget to do. I wind up not being able to check the weather on my iPod in the morning and I have to fall back to 20th century technology: the clock radio!
