Still having battery life issues on your iPhone 4S under iOS 5.0.1? We’ve already proven the issue is a software problem, not a hardware problem, which means Apple should be able to fix the iPhone 4S’s electric arterial spray… but when?

Real soon, as it happens. In fact, one Apple software engineer says the iOS 5.0.2 update is coming next week. In addition, Apple’s working on its first big point release of iOS 5, which will bring new extensions and abilities to Siri!

According to German Apple blog Macerkopf, an Apple engineer hard at work in the iOS division tells them that Apple has finally licked the battery problems, and will release the fix no later than the end of next week, bringing all iPhone 4Ses up to a standard 40 hours of standby and 10 hours of use.

More exciting, though, is what Apple has in store for iOS 5.1. Siri will apparently be getting some incredible new functionality, including support for these commands:

Take a picture.

Make a video.

Switch on/off WiFi

Switch on/off BlueTooth

If true, not only is Siri going to become even more integrated with the iPhone 4S and iOS 5, but it sets a great standard for future point releases, where Apple makes Siri even more smart every few months by expanding her vocabulary. Unfortunately, outside of word that Apple’s working on the update, there’s no ETA, but I think most of us would be happy with the battery life being fixed for now, don’t you?
