Many of you have been suffering at the hands of the battery-hogging Google Play Services app recently. That is about to change with the latest update to the GPS app, to version 4.1, which brings with it some significant battery performance improvements for users with Location Reporting enabled. Google Play Services is the app that manages basically every aspect of your Android device outside major firmware upgrades: GPS controls the updating of all the apps on your device. Obviously, it has a tendency to be power-hungry.
Version 4.1 brings more to the table than just improved battery performance (although that is by far the most significant change). The version change will also allow developers to institute turn-based multi-player in Play Games, which will also see automatic updates of turn-data to Play Services to be shared with your opponents/friends. A new preview Google Drive API is also included that allows you to read and write files in Drive across devices, both on- and offline. There's also some ad-related additions and Google+ sharing and connection improvements.
The official Android Developers Blog announced the update on January 9th, but now we have the APK download link. The update will appear silently on your device in the coming days, but if you don't want to wait that long, you can install the APK directly below.
Have you updated the Play Services app already? Have you noticed an improvement in battery performance when Location Reporting is enabled?
