Windows 10 Mobile accounts now for 14 percent of all Windows phone devices on the market according to the latest AdDuplex Report for August. The number is a significant increase from 11 percent in June and doubled its previous monthly growth of 0.5 percent to one percent. Nonetheless, without a firm number of active devices month to month it's hard to know if the increased rate is due to wider adoption of new Windows 10 Mobile handsets, 8.1 phones being updated to Windows 10 Mobile, or just 8.1 users leaving the market (very likely).

Putting aside the well-known overall low market share of Windows phone compared to Android and iOS the increased ratio of Windows 10 Mobile is useful for developers who want to target devices using the Universal Windows Platform (UWP). Some companies have put off or downplayed the need for a Windows 10 Mobile app e.g. WhatsApp due to the large 8.1 install base. That number is still in favor for 8.1 at 77.3 percent of all devices, but Windows 10 Mobile appears to have the momentum in growth.

For the foreseeable future, however, it will be a slow grind for fans of Windows phone. Mobile Anniversary Update sees broad adoption Perhaps more interestingly, over half of all Windows 10 Mobile handsets – 52.4 percent – are already on the Mobile Anniversary Update with 41.3 percent still on the 1511 build from last year. The Anniversary Update (aka Redstone 1) only came out last week as an official update and just yesterday for carrier-supported devices. That rate of uptake suggests many users are likely on the Insider program and are early-adopters putting the final bits on their phone a few weeks ago.
