Manufacturer Company Profile
OnePlus was founded in December 2013 in Shenzhen, China by former Oppo executives with a vision to bring premium experiences at mid-range prices. From the first device «OnePlus One» with the motto «Never Settle», it created a feedback-driven design culture through strong community support. In 2014 it partnered with Cyanogen Inc. for stock Android ROM and in 2016 launched its own OxygenOS. Expansion into the wearable market came in 2021 with the first OnePlus Watch, which won awards for value-for-money and design.
With a focus on rapid software updates (4 Major Android OS updates, 5 years of security patches), OnePlus invests in R&D centers across five continents and partners with top names such as Qualcomm, Google and Google Health Connect. In the wearables space, it moved to partner with Google for Wear OS and adopted Snapdragon W5 Gen 1 chipsets for top energy efficiency.
At the same time, it incorporates AI and machine learning technologies for improved health tracking (AI sleep & stress analysis), while investing in sustainable solutions: eco-friendly packaging and plastic reduction. In ten years, OnePlus has sold over 25 million smartphones and wearable devices, earning loyal users for its community-first development model and dedication to quality.
