The developer also claims that Windows Phone 8.1 will bring the ability to opt out of the native messaging application, thus allowing users to send or receive texts using third party messaging apps. “Battery Power Sense” is said to be a feature that would let users track and monitor the battery life of their device. Windows Phone 8.1 may also bring support for installing apps on a SD card and the addition of an iCloud account. One major change that this update is expected to bring is Action Center, essentially a notification center that will intelligently be able to manage notifications. So far its not known when Microsoft is going to release this update, but as far as rumors go, we can expect WP 8.1 to drop within the next couple of months.
