Over the last few days, bits of information have been leaking out over what may be the next build of Windows 10 Mobile for Insiders. Currently, Microsoft has all their focus on getting the desktop version of Windows 10 ready for the July 29 launch as evident from their three releases this week.

Although the changes are not massive from the posted screenshots, presumably the performance, reliability and battery life are all also better. Here are the items identified as new in 10158.
