Earlier today, Microsoft unleashed a new update for their Battery Saver app. At the time, there was no changelog posted, so instead we had to infer the changes, some of which were obvious.

Tonight, Microsoft has updated the changelog in the Store, and it is a whopper, with many details about the refreshed system app. Even more, the changelog refers to Windows Phone 8.1 build 14203. The current Windows Phone 8.1.1 build for the Preview for Developers program is 14192, meaning there is a good chance Windows Phone users are about to get another OS update very soon.

Evidently, the newest build of Windows Phone 8.1.1 enables a 'Real Time Live Tile' for Battery Saver, which is the first of its kind for Windows Phone. The other big new feature that the 14203 Windows Phone 8.1.1 update brings is the ability for users to add Battery Saver to the Quick Settings found in the Action and Notification Center.
