OxygenOS Ending Officially Confirmed: What OnePlus Users in India Need to Know
OxygenOS Ending has officially become a reality as OnePlus announces a major software strategy change. While the news has sparked concerns among long-time fans, the transition does not mean the company is shutting down or exiting important markets like India. Instead, OnePlus is preparing to simplify its software ecosystem by gradually moving eligible devices to ColorOS.
OxygenOS Ending: Why OnePlus Is Replacing OxygenOS with ColorOS
For years, OxygenOS was one of the biggest reasons behind OnePlus’ popularity. Its clean interface, smooth performance, and minimal design helped the brand stand out in the Android market. However, after the codebase merger with OPPO several years ago, OxygenOS and ColorOS have become increasingly similar with every major update.
Now, OnePlus has officially confirmed that eligible global devices will have the option to upgrade to ColorOS after the release of ColorOS 17. The company believes that maintaining a single software platform will allow faster software updates, better optimization, improved stability, and more efficient engineering resources.

OxygenOS Ending Does Not Mean OnePlus Is Leaving India
The simple answer is no.
The company’s recent announcement regarding operational changes only affects future product launches in Europe and North America. OnePlus India continues to operate normally and has several upcoming smartphones, tablets, and audio products planned for the Indian market.
Product development in the smartphone industry begins years before launch. Continued investments, product planning, and ongoing community events clearly indicate that OnePlus remains committed to India.
OxygenOS Ending: What Existing OnePlus Users Should Expect
Current OnePlus users will continue receiving software updates and security patches according to the company’s existing update policy. Warranty coverage, customer support, and repair services will also remain unchanged.
OnePlus has also confirmed that the migration to ColorOS will be optional for eligible devices. Users who choose to switch and later prefer the previous experience will also have access to a rollback option to OxygenOS, providing additional flexibility.
Why OxygenOS Ending Makes Sense for OnePlus and OPPO
From a software engineering perspective, maintaining two nearly identical operating systems requires significant development resources. By focusing on a unified platform, OnePlus and OPPO can deliver updates more quickly, reduce software fragmentation, and improve the overall user experience.
Although the decision makes practical business sense, many long-time OnePlus fans will undoubtedly miss the OxygenOS brand, which represented the company’s “Never Settle” philosophy and became a defining part of its identity.
OxygenOS Ending Marks the End of an Era
The end of OxygenOS marks the closing of an important chapter in OnePlus history. While the branding may disappear, the company’s focus now shifts toward delivering a stronger and more efficient software experience through ColorOS. Most importantly, Indian users can remain confident that OnePlus is continuing its business, launching new products, and supporting existing devices for years to come.

OnePlus 13 OxygenOS 16.1 Update Brings Major Battery and Performance Improvements Before July Patch

OnePlus 13 OxygenOS 16.1 Update is finally delivering the improvements many users have been waiting for. After receiving a recent software update of around 400MB, the flagship device now offers noticeably better battery life, improved thermal management, and enhanced overall performance. While the official changelog mainly mentions system stability enhancements, real-world testing reveals that the update includes much more behind the scenes.
OnePlus 13 OxygenOS 16.1 Update Improves Battery Life
One of the biggest improvements after installing the latest OxygenOS 16.1 update is battery performance. Earlier software builds delivered approximately five hours of screen-on time during normal daily usage. However, after updating to the latest version, battery endurance has increased to around six hours and thirty-seven minutes, even with heavy benchmarking and stress testing.
The update also appears to optimize power consumption during demanding tasks such as CPU throttling tests, benchmark applications, and graphics stress tests. Users looking for longer battery life on the OnePlus 13 should notice a meaningful difference after upgrading.
OnePlus 13 OxygenOS 16.1 Update Enhances Performance
Another noticeable improvement is heat management. Previous software versions caused the device to warm up even during regular use. After installing the latest build, heating has reduced significantly, including while charging the phone.
Performance has also received a welcome boost. Benchmark testing shows slight gains in Geekbench single-core and multi-core scores, while AnTuTu scores increased by nearly one lakh points compared to the previous build. GPU stability during graphics-intensive testing also improved, indicating that OnePlus has optimized the device for sustained performance rather than simply increasing benchmark numbers.
July OxygenOS 16.1 Update Expected Soon
The current update focuses mainly on stability improvements, but another software release is expected shortly. The upcoming July OxygenOS 16.1 update is likely to include the July 2026 Android security patch along with additional customization features, including new fingerprint animations that have already started appearing on newer OnePlus devices in other regions.
Although there is a slight increase in overnight battery drain compared to the previous version, the overall user experience is considerably better thanks to stronger battery endurance, cooler temperatures, and smoother day-to-day performance.
Should You Install the Update?
If the latest OxygenOS 16.1 update is available for your OnePlus 13, it is recommended to install it. Despite being a relatively small update, it delivers meaningful improvements that users can notice in everyday usage. Better battery backup, improved thermal efficiency, and enhanced system performance make this one of the more worthwhile OxygenOS updates released for the OnePlus 13 so far.

Another welcome improvement is the dark mode optimization, where Quick Settings tiles now properly adapt to the dark theme for a more consistent interface.
The Gallery app has also received a refreshed layout with a dedicated “Create” section that neatly organizes AI-powered tools such as AI Portrait Glow, AI Detail Boost, AI Eraser, HD Collage, and the built-in video editor.
OxygenOS 16.1 July Update Improves Gaming Performance
Gamers will appreciate the improvements made to the Game Dashboard. The update introduces new visual filters, including Ultra HD, Color Enhancement, Night Vision, and Film Grain, allowing users to customize visuals according to their preference.
OnePlus has also expanded its gaming audio settings by adding customizable equalizers and improving Sound Boost for clearer footsteps, enhanced environmental sounds, and sharper in-game voice effects.
OxygenOS 16.1 July Update Adds More Customization Options
Customization receives a major boost with the latest update. Users can now mix and match fingerprint icons with different unlock animations instead of being limited to predefined combinations. Even better, custom emojis, letters, and numbers can now be used as fingerprint icons, making the lock screen feel more personal.
The Camera application also gains two new filters designed for portrait and street photography, giving users additional creative options without relying on third-party editing apps.
OxygenOS 16.1 July Update Enhances Battery and Performance
Initial testing shows noticeable improvements in battery efficiency during heavy workloads such as benchmarking, gaming, and CPU stress tests. The device experiences less overheating compared to previous builds, resulting in more stable performance throughout extended usage.
Benchmark scores remain largely consistent, but thermal management appears significantly better, making the overall software experience smoother and more reliable.
Should You Install the OxygenOS 16.1 July Update?
The OxygenOS 16.1 July Update is more than just a monthly security release. It introduces meaningful usability improvements, better customization, enhanced gaming features, refined camera tools, and improved battery optimization. If you own a supported OnePlus smartphone, this update is highly recommended and delivers one of the most polished software experiences released by OnePlus in recent months.
