iOS 5.0.1 brings the following improvements according to the official changelog:
- Fixes bugs affecting battery life.
- Adds Multitasking Gestures for original iPad
- Resolves bugs with Documents in the Cloud
- Improves voice recognition for Australian users using dictation
Some users have suffered from battery issues on the iPhone 4S since its release. Apple claims that it is a software issue that can be fixed via this update.
iOS 5.0.1 is available for users of all devices that run iOS 5. Since it is a delta update, users do not need to download the whole OS. The update is just 40-55 MB in size depending on the device. To download the update directly to the device, go to Settings, General, Software Update. The update is not available over-the-air in all countries, but it is rolling out slowly.
