iOS 4.3 brought enhanced AirPlay, a speedier Safari, iTunes Home Sharing, and more to iOS device users, but it appears that iOS 4.3 has brought another thing, a seemingly negative one: subpar battery life. A number of readers have written in to less us know that since upgrading to iOS 4.3 their battery life has been “drastically” worse. One report to us claims random battery life drops in 15-20% increments.

This battery life bug in iOS 4.3 could come as a natural bug in the operating system, or could be related to some of the new features present in the latest system upgrade. It is possible that the faster rendering in iOS Safari uses more processing power, furthermore battery life. Another possibility could be the new Ping push notification feature, which runs in the background.

A number of users are reporting in Apple’s official support discussion forums that their devices are, too, experiencing battery life that is subpar to their experience in earlier versions of iOS:

Some users figure this issue is the result of multiple applications running in the background, however, this report seems to challenge that:

I have personally noticed battery life issues myself in both an iPhone 4 and an iPad 2 – more so on the iPad 2, though. What about you? Let us know in this poll and the comments.
