Last month, OnePlus released the first beta of Android 11 for the OnePlus 6 and OnePlus 6 T, allowing power users to test drive the new software ahead of the stable release. This was followed by the second beta release towards the end of July, which optimized the overheating control management and enhanced 5G and Wi-Fi connectivity. Now both phones are receiving a new beta update which further refines the software experience.

The third beta OxygenOS 11 beta, is rolling out to the OnePlus 6 and 6T as OnePlus continues to patch issues and iron out annoying bugs. The new update promises to improve the smoothness of YouTube videos, fixes a bug related to the Work-Life Balance feature, and optimizes background process management for improved battery life.
