Nothing OS 4 brings Android 16 to compatible Nothing smartphones, introducing smoother animations, improved multitasking, smarter Glyph features, and additional customization options. The update continues Nothing’s minimalist approach while making everyday smartphone interactions more convenient.

But how well does Nothing OS 4 actually perform? Does it improve PUBG Mobile gaming? Can it extend battery life, and should users worry about overheating?

These questions matter more than attractive screenshots or promotional promises.

In this Nothing OS 4 review, we explore the confirmed features, supported devices, gaming capabilities, battery optimization, and performance limitations. We also examine Nothing Phone (3) specifications, charging speed, and prices in Pakistan and international markets.

The goal is simple: help you understand what the software improves and what still depends on your smartphone’s hardware.

What Is Nothing OS 4?

Nothing OS 4.0 is Nothing’s custom operating system built on Android 16, offering a refined interface, smoother performance, and enhanced features for compatible Nothing smartphones. It builds on earlier Nothing OS releases with cleaner visuals, improved responsiveness, additional widgets, and better multitasking controls.

Unlike heavily customized Android interfaces, Nothing OS focuses on simplicity. Its distinctive dot-inspired design, restrained colors, and recognizable widgets create a consistent visual experience.

The update also improves application management and introduces additional AI transparency features.

According to the official Nothing OS 4 release announcement, the company focused on smoother interactions, visual consistency, and practical improvements based on community feedback.

However, Nothing OS 4 is software, not a smartphone model. Battery capacity, charging wattage, camera specifications, and gaming performance depend on the device running it.

Nothing OS 4 Features and Improvements

Refreshed Interface and Smoother Animations

Nothing redesigned its first-party application icons and status-bar indicators to improve visual consistency.

The update introduces new lock-screen clock designs, refined gesture animations, and smoother transitions between applications.

These changes make navigation feel more polished, especially when switching between frequently used apps.

However, improved animations do not automatically increase processing power.

Think of it like organizing your workspace. Everything becomes easier to access, but your computer does not magically receive a faster processor.

Improved Pop-up View and Multitasking

Nothing OS 4 introduces a refined Pop-up View that supports two floating applications.

Users can switch between compatible apps without repeatedly returning to the home screen.

For example, you can reply to messages while checking delivery information or browsing another application.

The update also adds 2×2 Quick Settings tiles, providing more flexibility when organizing frequently used controls.

These improvements are particularly useful for people who regularly multitask on their smartphones.

Extra Dark Mode

Extra Dark Mode expands darker visual elements throughout the interface.

The feature improves nighttime viewing comfort while potentially reducing battery consumption on OLED displays.

OLED screens can consume less power when displaying darker content, although actual savings depend on brightness, applications, and usage patterns.

Therefore, Extra Dark Mode may help battery efficiency, but it cannot guarantee a specific improvement in battery life.

Hidden Apps and Additional Widgets

Nothing OS 4 allows users to hide selected applications from the app drawer.

This feature helps reduce visual clutter without requiring users to uninstall their applications.

However, hiding an application does not provide the same protection as a secure private space.

The update also introduces additional widget sizes for Weather, Pedometer, and Screen Time.

Users can create more personalized home screens while keeping important information accessible.

Glyph Interface and AI Features

The Glyph Interface stands out as one of Nothing’s signature innovations, combining distinctive lighting effects with practical features that enhance everyday smartphone interactions.

Nothing OS 4 expands Glyph Progress using Android 16 Live Updates.

Compatible applications can display progress information for activities such as deliveries, rides, and timers through supported Glyph hardware.

This reduces the need to unlock your smartphone repeatedly.

However, availability depends on application compatibility and the phone’s hardware capabilities.

Nothing Phone (3) also receives exclusive Glyph Matrix improvements, including Pocket Mode, additional Glyph Toys, and smarter Flip to Glyph behavior.

The availability and functionality of these features vary across Nothing smartphones, depending on each device’s hardware and software compatibility.

AI Transparency and Essential Apps

Nothing OS 4 introduces AI status indicators and usage information.

These features help users understand when supported AI functions become active.

Nothing also introduced Playground and Essential Apps, giving users access to community-developed tools and AI-powered widgets that offer greater customization and a more personalized smartphone experience.

Some capabilities require separate updates or compatible hardware.

Consequently, users should check individual feature availability rather than assuming every Nothing OS 4 device includes identical AI functionality.

Nothing OS 4 Supported Devices

Nothing initially introduced OS 4.0 for Phone (3) before expanding the rollout to other eligible smartphones.

Supported devices include:

• Nothing Phone (3)
• Nothing Phone (3a) Pro
• Nothing Phone (3a)
• Nothing Phone (2)
• Nothing Phone (2a)
• Nothing Phone (2a) Plus
• Selected compatible CMF smartphones

Nothing subsequently completed its OS 4.0 rollout for eligible devices.

By October 2026, Nothing OS 4.1 had also reached eligible smartphones.

However, hardware-dependent features may differ between models.

To check your current software version and available updates, navigate to Settings > System > System Update on your Nothing smartphone.

For optimal performance, improved security, and reliable functionality, keep your Nothing smartphone updated with the latest stable software version officially available for your device.

Nothing OS 4 Performance and Speed

Nothing OS 4 focuses on improved responsiveness, consistent animations, and application optimization.

Its System and Apps Dashboard helps users review background activity and manage application performance.

These improvements can make everyday smartphone interactions more convenient.

However, software optimization cannot eliminate hardware limitations.

For example, Nothing Phone (3) uses Qualcomm’s Snapdragon 8s Gen 4 processor, while older Nothing smartphones use different chipsets.

Two devices running the same operating system may therefore deliver noticeably different performance.

RAM capacity, storage conditions, background applications, and temperature also influence responsiveness.

For demanding tasks, the processor and cooling system remain particularly important.

Nothing OS 4 PUBG Gaming Performance

Can Nothing OS 4 handle PUBG Mobile?

Yes, compatible Nothing smartphones can run PUBG Mobile, but performance depends primarily on their hardware.

Nothing Phone (3) combines a Snapdragon 8s Gen 4 processor with an Adreno 825 GPU and a 120Hz AMOLED display.

This combination provides capable hardware for demanding Android games.

However, a 120Hz display does not guarantee 120fps gameplay.

PUBG Mobile determines available frame-rate settings based on device compatibility, graphics settings, and game updates.

There is no verified universal PUBG FPS improvement attributable specifically to Nothing OS 4.

Does Nothing Phone (3) Heat During Gaming?

Heating is an important consideration for mobile gamers.

In its independent Nothing Phone (3) performance review, GSMArena reported substantial thermal throttling during prolonged demanding stress tests.

The phone also became noticeably hot under intensive workloads.

However, synthetic stress testing does not perfectly represent ordinary PUBG gameplay.

Gaming duration, room temperature, graphics settings, and background activity can influence heating.

Players who prioritize stable performance should consider balanced graphics settings and avoid charging during intensive gaming when possible.

Without verified Nothing OS 4-specific PUBG testing, claiming an exact average FPS would be misleading.

Nothing OS 4 Battery Life and Charging

Nothing OS 4 includes battery-conscious features such as Extra Dark Mode and system optimization.

However, battery endurance depends on the smartphone’s hardware and individual usage.

Nothing Phone (3) provides a useful example.

Battery Capacity and Endurance

The international Nothing Phone (3) features a 5,150mAh battery.

The Indian version uses a larger 5,500mAh battery, making regional specifications important.

In GSMArena’s standardized testing, the international model achieved a 12-hour, 56-minute Active Use Score.

This figure represents a mixed-use benchmark rather than guaranteed continuous screen-on time.

Actual endurance depends on screen brightness, gaming, mobile connectivity, navigation, and application activity.

Charging Wattage and Duration

Nothing Phone (3) supports several charging methods.

Nothing estimates approximately one hour for a complete wired charge using suitable charging equipment.

Charging temperature, charger compatibility, and background activity can influence actual results.

Importantly, 65W represents the supported maximum charging power, not a constant rate throughout the entire charging cycle.

Nothing Phone (3) Specifications

Because Nothing OS 4 supports multiple smartphones, Phone (3) offers a practical hardware reference.

The phone features a main camera, ultra-wide camera, and periscope telephoto camera with 3x optical zoom.

It also includes stereo speakers and Nothing’s distinctive rear Glyph Matrix.

Nothing Phone Price in Pakistan 2026

Nothing OS 4 does not have a separate purchase price. Eligible owners can receive supported software updates without purchasing another smartphone.

However, Nothing smartphone prices vary by model, configuration, and region.

For Pakistan-based buyers, Nothing Phone (3) provides a premium hardware reference.

Both NothingShop.pk and Jazz’s online store have listed the Phone (3) 16GB/512GB configuration at approximately PKR 329,999.

This represents an advertised retailer price rather than a guaranteed nationwide market rate.

Before purchasing, confirm stock availability, PTA approval, warranty coverage, and the exact regional variant.

Nothing Phone (3) International Price

Nothing introduced Phone (3) with the following US retail prices:

These are official launch reference prices, not guaranteed current checkout prices.

Retail pricing can change because of promotions, taxes, currency exchange rates, and regional distribution.

International buyers should compare current local offers and warranty conditions before making a purchase.

Camera, Display and Everyday Experience

Nothing Phone (3) features a sharp AMOLED display, a high refresh rate, and a distinctive transparent-inspired design.

Its camera system provides several focal lengths for everyday photography.

The periscope telephoto camera offers more flexibility than basic digital zoom.

Nothing OS 4 complements the hardware through interface refinements and supported application improvements.

However, software cannot guarantee identical photography results across different Nothing models.

Is Nothing OS 4 Worth Installing?

Nothing OS 4 delivers meaningful improvements for users who appreciate minimalist design, customization, and convenient multitasking.

Its refined interface, additional widgets, AI transparency controls, and Glyph enhancements improve the overall experience.

However, users should maintain realistic expectations.

A software update cannot guarantee higher PUBG frame rates, eliminate thermal throttling, or increase physical battery capacity.

Because newer Nothing OS 4.1 builds are available for eligible devices, check your smartphone’s latest stable firmware before updating.

Back up important information and review your device-specific changelog before installation.
