Apple has produced some of the most memorable adverts in history. Its “1984” commercial for the original Macintosh is still talked about today, and we can all remember the “Mac vs. PC” commercials, and the dancing silhouettes that were used to promote the iPod. However, it hasn’t quite been the same story in recent years.

Despite promoting incredibly popular products like the iPhone and the iPad, Apple’s most recent commercials have been far from unforgettable. In fact, the CEO of one ad-tracking firm has revealed that Apple is being mocked for its latest Siri commercials, which employ celebrities to sell a feature that rarely works in real life.

Since Apple introduced iOS 4.3 last week, I’ve found a number of complaints about battery issues with the firmware update. I’ve even experienced these problems personally and I know many of you have too.

The update has caused issues with the battery life on my iPhone 4 and my iPad 2 is getting considerably less time out of its battery than my old iPad running iOS 4.2.1, so if you haven’t upgraded to iOS 4.3 you may want to wait until this issue is resolved.

According to users on Apple Discussions under the topics iPhone 4 – ios 4.3 – Battery Drain and iOS 4.3 causing battery drain, the iPhone’s battery life is severely shortened by the latest iOS update. As a result some users are also complaining that battery life is lasting 2 to 4 hours less than before the update was applied.

Ars Technica stumbled upon an interesting tidbit while reviewing their 11-inch MacBook Air.  They found a compelling reason for Apple to not install Adobe Flash on the MacBook Air and it wasn’t just because they wanted to make sure users always had the latest version of Flash.

We’ve received some comments from iPhone 3GS users that their battery life after the iOS 4 update has declined. This can in most cases be attributed to poorly written apps or apps that don’t support the multitasking feature introduced in iOS 4. Are you experiencing this problem? Have you identified an app or some other reason for the decline in battery life on your iPhone 3GS? Tells us all about it in the comments.
