Apple has unveiled via the WWDC 2015 that iOS 9 will soon replace iOS 8 and a beta download is ready for those willing to take the operating system for a spin. The tech giant indicated that two key improvements will be deployed with the software that likely will be first experienced once the iPhone 6S is out.

Insufficient battery life plagues mobile device users but with the iOS 9 Apple appears to present an upcoming software solution. The same goes with the iOS update process that in the soon-to-arrive version will reportedly be an experience made significantly easier from last year's iOS 8.

Battery Life Extension

According to Apple, iOS 9 is already optimized to extend the normal iPhone operating hours by another hour but a new featured hardcoded with the software will further bump the device battery life up by at least three more hours. Craig Federighi, the company software chief, said tweaks implemented on iOS 9 will see the mobile OS "pulling levers you didn't even know existed."

Federighi called this innovative feature, a background operator, Low Power Mode, BGR said in a report. The core function is to reduce battery usage at a given chance, Apple said.

For instance, iOS 9 will automatically detect if an iPhone is placed on a table facedown, preventing the screen from lighting up even when a message is received. The device will have the same response in cases of notification alarms or incoming calls, Apple said.

OS Update Made Easier

In 2014, the iOS 8 release caused uproar when the software required over 4GB of free storage space for the update to progress. As a result, many Apple fans delayed their update plans or simply elected to skip the whole process. But those brave enough to make the jump were greeted by tedious procedures that mostly were suffered through by iPhone owners with the basic 16GB configuration.

Starting with iOS 9, updating the iPhone software is virtually a walk in the park. For starters, the steps will be more user-friendly and the storage issue will be a thing of the past. The next iOS version will be up and running on mere 1.3GB of internal disk space, a far cry, Business Insider said, from the 4.6GB gobbled up by iOS 8 last year.

It was a painful lesson learned for Apple as its huge iOS 8 mistake slowed down the projected migration to the operating system, serving as a blot to the otherwise sterling iPhone update history maintained by Apple.

The first beta version of iOS 9 is now ready to download but the final cut will not be ready until later in the year. The rollout will likely happen at the same time with that of the iPhone 6S release date, which should be between September and October 2015.
