The Future of Mission-Critical Communications: From Coverage Challenges to Continuous Assurance Mission-critical communications has firmly emerged as one of the defining themes shaping the industry in 2026. From the global stage at Mobile World Congress 2026 to the UK-focused discussions at BAPCO Annual Event 2026, one message is clear: the expectations placed on public safety networks are increasing faster than ever before. As organisations transition from legacy systems to broadband technologies, the challenge is no longer just about enabling connectivity—it’s about guaranteeing performance, resilience, and trust in real-world conditions. Voice Remains the Foundation—But Expectations Are Evolving While data, video, and AI-driven capabilities are rapidly expanding, mission-critical voice still underpins emergency operations. However, moving from TETRA to LTE and 5G introduces new challenges: Less predictable coverage Increased dependency on network conditions Greater variability in user experience For emergency responders, this shift is not just technical—it’s operational. The need is no longer just connectivity, but guaranteed performance in real-world conditions. Coverage and Resilience: The Reality Behind the Transition One of the biggest misconceptions is that modern networks automatically outperform legacy systems. In reality: Higher-frequency networks (4G/5G) create more localized coverage gaps Indoor performance remains a significant challenge Network changes often lead to user-perceived degradation, even when overall performance improves At the same time, resilience is evolving from: Single-network reliability → Multi-layered service assurance This means organisations must move beyond infrastructure and ask: “How do we continuously verify that services are actually working for the end user?” SmartViser Approach: From Validation to Continuous Assurance To successfully transition to broadband mission-critical communications, organisations must address two key needs: Validate and test services before deployment Continuously monitor and assure performance in live operations SmartViser supports both phases with a comprehensive, device-based approach. 1. Active Testing – Validating Mission-Critical Services Before Deployment Before any rollout, it is essential to validate that mission-critical services perform as expected under real conditions. With viSer Neo and viSer Neo+, SmartViser enables: End-to-end testing of MCX services, including: Push-to-Talk (MCPTT) Data services and application performance Measurement of key KPIs such as: Call setup time Mouth-to-ear latency Audio quality (POLQA-based MOS) Data throughput and latency Execution of automated, repeatable test scenarios across: Lab environments Field conditions Mobility and drive testing With viSer Neo+, operators can go even deeper: Low-layer signalling analysis RF measurements and cell-level insights Advanced troubleshooting and optimisation Outcome: Ensure mission-critical services are fully validated, benchmarked, and ready for operational use before deployment. 2. Service Assurance – Continuous Monitoring in Live Networks Validation alone is not enough. Once deployed, services must be continuously monitored to ensure consistent performance over time. SmartViser enables full service assurance through: viSer Tempo – Active Monitoring Continuous execution of automated test scenarios Real-time validation of service availability and performance Early detection of degradation before it impacts users viSer Mateo – Passive Monitoring Collection of real usage data from operational devices Insight into actual user experience and environmental conditions Identification of trends, anomalies, and intermittent issues Outcome: From periodic testing → continuous, real-time assurance of QoE and QoS Customer Story: ACMOSS and the French RRF Programme A strong example of this approach in action is ACMOSS and the deployment of the Réseau Radio du Futur (RRF)—France’s nationwide mission-critical broadband network. To ensure performance and user experience across this complex, multi-operator environment, ACMOSS implemented SmartViser viSer Tempo as part of its operational framework. Key highlights include: Deployment of automated smartphone-based testing farms simulating real user behaviour End-to-end validation of MCX services, including voice, Push-to-Talk and data Measurement of critical KPIs such as: PTT access time Mouth-to-ear latency Audio quality (MOS) Integration into the Network Operations Centre (NOC) for real-time visibility This approach allows ACMOSS to: Continuously monitor service performance across the RRF Detect issues before users are impacted Maintain service continuity and resilience at all times As highlighted in their publication, this data-driven methodology ensures that critical communications remain available and performant across all operators and scenarios. Read the full customer story here:ACMOSS RRF Quality of Experience Article Multi-Bearer Future: Testing the Complexity of Tomorrow The future of mission-critical communications is multi-bearer: 4G / 5G Satellite (LEO constellations) Private networks Wi-Fi and hybrid connectivity This creates a new level of complexity: Dynamic switching between networks Variable latency and bandwidth Increased risk of service disruption SmartViser solutions allow operators and agencies to: Validate performance across all bearers Ensure seamless service continuity Benchmark hybrid connectivity strategies From Reactive to Proactive: A New Operational Model Historically, mission-critical communications have been managed reactively: Issues are reported → investigated → resolved But in a 5G and multi-service world, this model is no longer sufficient. The new model is: Continuous monitoring Early detection of degradation Data-driven optimisation SmartViser enables this transformation by combining: Active testing (viSer Neo / Neo+) Continuous monitoring (Tempo) Real user insight (Mateo) Conclusion: Enabling the Future of Mission-Critical Communications The transition to broadband and multi-bearer communications is inevitable—but success is not guaranteed. To deliver on the promise of: Reliable voice Real-time data Seamless user experience Organisations must adopt a new mindset: From network-centric → experience-centric From reactive → proactive From assumptions → measurable assurance SmartViser enables this transformation by covering the full lifecycle: Validation before deployment (viSer Neo / Neo+) Continuous assurance in live networks (Tempo / Mateo) Meet Us to Learn More Want to explore how SmartViser can support your mission-critical strategy?

A deep dive into the status, advantages, and challenges of VoNR — and how 5G voice performs in real-world tests. 5G has largely been adopted as a “data network” — the early 5G deployment modes were Non-Standalone (NSA), which piggyback on 4G LTE infrastructure for control plane and fall back to LTE (or earlier) for voice calls. But as operators roll out 5G Standalone (SA) cores and more complete 5G networks, the next frontier is VoNR  — Voice over New Radio — i.e. native voice calls over 5G without relying on legacy networks. What is VoNR (Voice over New Radio)? VoNR (sometimes called “5G Calling,” “Voice over 5G Standalone,” or simply Vo5G) refers to the capability to carry voice (and SMS/other communication services) entirely over a 5G network (i.e. 5G RAN + 5G core + IMS) without having to fall back to 4G/3G for voice. In the 3GPP and GSMA frameworks, VoNR is a natural evolution from VoLTE: the voice is delivered over an IP Multimedia Subsystem (IMS) but using 5G radio. In practice, for VoNR to work, several prerequisites must be in place:  5G Standalone (SA) deployment (i.e., decoupled from LTE)  Radio coverage and capacity across frequency bands, especially in lower bands for broad coverage.  Devices (smartphones, modules) with firmware and hardware support for VoNR  Operator network support on IMS, radio, signaling, fallback mechanisms, etc. Because many existing 5G deployments are still NSA or mix 4G/5G, full VoNR readiness is a multi-phase transition. Current Status & Deployment (Mid-2025) Here’s a snapshot of where VoNR stands today : Global progress According to GSA’s “Global Progress to Voice over New Radio” report (October 2021), of many operators globally:  Some are evaluating or trialing VoNR  A smaller number are planning deployment  Only a few have soft-launched or deployed VoNR in a limited capacity Many operators are still relying on intermediate fallback solutions such as EPS Fallback (EPS-FB)  or hybrid mode, until coverage and maturity of 5G SA is adequate. Some regions with more advanced 5G SA deployment (e.g. parts of China, USA, and Singapore) have begun rolling out VoNR or testing it in live networks. UK / Europe In the UK, operators such as EE have already made public moves toward enabling VoNR / “5G Calling.” EE, for example, has set up a “5G+” branded network and provides instructions for enabling VoNR (5G Calling) on compatible devices. EE reportedly enabled “VoNR or 5G Calling” as of 6 June 2025 for devices that meet certain criteria (SIM, handset, plan) in areas with 5G+ coverage. However, coverage is still limited and selective; not all geographic areas or devices are yet supported, but an initial list can be found here. In Europe more broadly, some operators in Germany, for instance, Vodafone, have activated VoNR in certain cities. United States In the United States, T-Mobile US  was the first carrier to launch commercial Voice over New Radio (VoNR) services back in June 2022, marking a significant milestone in 5G evolution. Since then, T-Mobile has expanded VoNR availability across multiple cities — including New York, Seattle, Cincinnati, and New Orleans — while continuing to strengthen its 5G Standalone (SA) core capabilities. DISH Wireless (Boost)  has positioned itself as a VoNR leader, claiming coverage of more than 200 million POPs with native 5G voice supported across its nationwide network. AT&T  followed by announcing nationwide 5G SA in October 2025, progressively migrating customers onto the new core “in select areas every day.” This rollout lays the groundwork for AT&T to enable VoNR on a broader scale, though its FirstNet public safety network has yet to transition to SA. Meanwhile, Verizon  continues building out its 5G SA infrastructure — already deploying public-safety network slicing nationwide — and has successfully demonstrated VoNR sessions in partnership with Ericsson and MediaTek, including RedCap device testing. Although Verizon has not yet detailed commercial VoNR availability, its infrastructure progress indicates readiness for eventual deployment. Canada In Canada, Bell  became one of the first to activate VoNR for iPhone users in select areas such as the Greater Toronto Area (GTA) as of August 2025. TELUS  has also gone live with 5G Standalone in parts of Western Canada, with early users reporting VoNR availability in limited regions. Rogers , while heavily promoting 5G-Advanced features and continued SA expansion, has been less vocal about its VoNR deployment status. Together, these rollouts signal that North America is entering the next phase of 5G voice maturity, with the U.S. leading on commercial scale and Canada steadily following suit. So, while VoNR is no longer just a concept, it is still in an early/transition stage — with selective deployment, limited coverage, and device constraints. Advantages & Promised Benefits of VoNR VoNR brings several compelling advantages compared to legacy voice mechanisms (CS fallback, VoLTE, etc.). Some of them overlap with VoLTE’s improvements over 2G/3G, but VoNR can push further due to 5G’s capabilities. Improved user experience & voice quality Use of modern codecs (e.g. EVS, Adaptive Multi-Rate Wideband) allows high-definition (HD) or even “super HD” voice, with better clarity, lower distortion, and improved robustness under poor radio conditions. Faster call setup times (reduced latency in signaling) thanks to more direct paths in 5G network functions. The ability to stay entirely on 5G: a VoNR call does not force a fallback to 4G or older. This is especially beneficial when there’s background data or simultaneous usage of data services (maps, messaging, etc.) during calls. Network and architectural benefits Eventually, operators can phase out older technologies (2G/3G) more cleanly, reducing operational costs and complexity of maintaining aging networks. VoNR is an essential step in that migration. Learn more about the status of the network Sunsetting Simplification: When voice, data, messaging, and other services all run over a unified 5G/IMS infrastructure, there is less need for interworking between separate legacy systems, potentially reducing integration overhead. Better utilization of spectrum and radio resources: voice traffic in VoNR can benefit from 5G’s scheduling, beamforming, interference management, and dynamic allocation, making voice more efficient. Enhanced opportunities for value-added services: Because voice runs in the same domain as data, more tightly integrated features (video calling, conferencing, real-time collaboration, augmented reality voice + data combining) are easier to implement. For the operator, VoNR supports “future-proofing” and eventual decommissioning of legacy systems. Challenges, Risks & Limitations of VoNR The path to widespread VoNR deployment is not trivial. Below are key hurdles, some technical, some operational/business, and some strategic. Technical & engineering challenges Coverage & propagation constraints   To deliver voice everywhere, the 5G network must provide broad coverage (especially in rural / indoor / edge areas). Lower frequency bands (e.g. < 1 GHz) are required for deep coverage, but deployment and spectrum availability may lag.  In areas where 5G is weak or intermittent, fallback to 4G/VoLTE or earlier is still required. Ensuring seamless and reliable handover is non-trivial. Interworking and handover complexity   VoNR must interwork with VoLTE, 2G/3G (while they still exist), and WiFi/VoWiFi as needed. Seamless handovers between these domains (while maintaining call continuity) is difficult. Dual connectivity (5G + LTE) and fallback mechanisms need careful design to avoid drops or service loss. Device and chipset support   - Not all smartphones currently on the market support VoNR (or support it fully). Some require firmware updates or hardware that meets certain 5G SA and IMS requirements.  Power consumption: use of 5G for voice may increase battery use in certain bands or conditions (especially if radios frequently switch).   Ensuring backward compatibility with non-VoNR devices in the same network is a burden. IMS, signaling, and core network upgrades   Operators need to upgrade their IMS infrastructure, ensure compatibility with new 5G core network functions, support quality control, and handle new interfaces (e.g. “N5” / HTTP/2 interfaces as optional enhancements). Ensuring end-to-end QoS (quality of service) and stability for voice flows over 5G is more demanding (because voice is latency-sensitive).  More stringent real-time performance, monitoring and optimization are needed. Latency, jitter, and reliability under mobility / varying load   5G networks, especially early deployments, may have variable performance across cell edges, mobility, or under congestion. Maintaining high voice quality in such dynamics is challenging.  Packet loss, delay, and jitter can degrade voice unless well mitigated. How Smartviser Supports the 5G and VoNR Journey Implementing 5G Standalone (SA) and Voice over New Radio (VoNR) comes with many challenges — from testing coverage to ensuring voice quality. Smartviser helps operators, device makers, and chipset vendors address these challenges efficiently through its Viser test automation platform. With Smartviser, you can: Automate testing  across multiple technologies — 5G, LTE, Wi-Fi, and VoWiFi — to validate coverage and connectivity. Verify seamless handovers and interworking  between 5G and legacy networks (VoLTE, EPS fallback) to prevent call drops or service loss. Test devices and chipsets  to confirm full compatibility with VoNR standards — crucial for smartphone manufacturers and network operators. Measure and optimize power consumption , ensuring new 5G devices manage battery life effectively under VoNR operation. Assess voice quality and user experience  using reliable metrics like MOS and POLQA to guarantee crystal-clear voice calls. Monitor Quality of Experience (QoE) and Quality of Service (QoS)  end-to-end to maintain consistent network performance. Accelerate deployment  by automating repetitive testing tasks, reducing time to market, and ensuring higher reliability. See the Results in Action To demonstrate how VoNR performs in real-world conditions, Smartviser put the Xiaomi 15 5G through a series of controlled field tests using its Viser automation platform. These tests compared VoNR and VoLTE performance across live networks, measuring: MOS voice quality and clarity Call setup time Handover performance between 5G and LTE The results reveal how 5G Standalone and VoNR deliver measurable improvements in user experience — and where further optimization is still needed.

Mobile Network operators shutting down 3G and in some cases, 2G has been a long time coming. Operators across the world have either already shut down their 2G and 3G or are planning to do so in the near future. Up until now, we had several new technologies co-existing with legacy technologies, but it is becoming more complex for Carriers to manage and manufacturers to support. According to GSAs latest report July 2025 278 operators in 83 countries and territories have completed, planned, or are in the process of switching off their 2G and 3G networks an increase from 77 countries in December 2024. 2G networks : A total of 131 operators in 65 countries  have completed or scheduled closures (up from 128 operators in 63 countries). Within this group: 51 operators in 29 countries  have fully shut down 2G. 66 operators in 40 countries  have closures planned. 14 operators in 8 countries  are actively phasing out 2G. 3G networks : 147 operators in 62 countries  are either finished, planning, or currently switching off services. This includes: 78 operators in 40 countries  with completed closures. 50 operators in 32 countries  with switch-offs planned. 19 operators in 15 countries  mid-process. Some shutdowns are government-driven, such as the UK’s mandate to retire 2G by 2033. Others are operator group-led; for example, Orange has set a 2030 deadline for shutting down 2G and 3G in Europe, though the timeline may differ across its markets. Europe seems to lead in the number of switch-offs, followed by Asia and North America, although its share has decreased since December 2023. As legacy technologies are sunset operators continue with their upgrades to both 4G and 5G technology. According to GSA 31.5% will be upgrading to LTE only; 4.6% will be moving to 5G, 5.3% to 3G and LTE; and 1.5% will be upgrading to 3G, 4G, and 5G. Source: 2025 Global Mobile Suppliers Association Global Picture for 2G Source 2025 Global Mobile Suppliers Association Global Picture for 3G Source 2025 Global Mobile Suppliers Association In Europe , 3G is expected to be switched off before 2G. Around 19 operators are planning to switch off their 3G Network by 2025 and around eight operators are planning to switch off their 2G network by 2025. June 2021 brought the shutdown of 3G in two operators in Germany Vodafone and Deutsche Telekom. Telefonica is also expected to shut down 3G by the end of 2021. In other countries, Telia will look to close 3G in all their countries between 2022 and 2025 and EE will be the first UK network to announce the shutdown of 3G. A detailed breakdown is available in the table below. For Asia , 2G in countries like Japan was phased out a long time ago. The trend will continue with other countries and operators. A detailed breakdown is available. The Americas, especially the US is shutting down 2G networks on an accelerated scale. 3G networks will be shut down by all main operators by 2022. Around 15 operators in 7 countries have announced the closure of 2G by the end of 2025. A detailed breakdown is available in the table below. For Oceania , 2G is almost phased out. In Australia, all 3 operators have shut down their 2G by the end of 2018 and 3G is on the way with Telstra the only one announcing a timeline for the end of 2024. A detailed breakdown is available in the table below. Africa i s the only region where no 2G or 3G shutdowns have been announced so far but it will be part of future planning once newer technologies penetrate more. A detailed breakdown is available. What 2G/ 3G shutdowns will mean for end-users ? This will force/encourage people to upgrade their phones to 4G. Many Operators seem to suggest that 2G in Europe will be around until 2030 and this is mainly due to implications of the M2M and IoT applications. In particular, the EU-mandated eCall, where long term agreements are in place, will need to be supported by the 2G technology before the work towards migration to IMS voice is fully completed. There are several drivers behind this change. Reuse of frequencies for new technology deployments like 4G and 5G. Most 2G use 850, 900, 1,800 or 1,900 MHz frequency bands. The sub-1 GHz bands, are very valuable due to their propagation characteristics, especially delivering greater coverage and in-building penetration. Reduce costs and effort in maintaining legacy radio networks Lower the energy consumption of the network. Vodafone New Zealand has announced back in 2019 that they are expecting around 10% savings in power consumption from migrating away from 2G and 3G technologies. Simplify the network operation This 2G and 3G network closure change are bringing several challenges to device manufacturers, Carriers/Mobile Network Operators and Mobile Virtual Network Operators. What will this mean for Smartphone Manufacturers? IMS (VoLTE & VoWiFi) will need to now be enabled by default on all devices. This will add additional testing requirements to ensure smooth interoperability on all networks to enable end-users to benefit from the latest technology and not rely on legacy technology. Testing on Roaming conditions should also be taken into account to ensure end-users Quality of Experience when using data or voice services. What will this mean for Mobile Network Operators (MNOs)? The shutdown of 2G and 3G networks presents both strategic opportunities and operational challenges for MNOs. On one hand, retiring legacy technologies will enable operators to reduce operational and maintenance costs, streamline spectrum use, and reallocate valuable frequency bands to more efficient 4G and 5G networks. This transition supports improved data speeds, lower latency, and future-ready network architectures. However, these benefits come with important caveats. Operators must ensure robust 4G VoLTE coverage and sufficient network capacity before fully decommissioning 3G, as gaps in VoLTE availability could force users to fall back on 2G voice, leading to poor call quality and degraded customer experience. In areas where 2G is also being retired, this could result in service disruption, dropped calls, or loss of connectivity, ultimately damaging customer trust and brand loyalty. To mitigate these risks, MNOs should: Expand IMS (IP Multimedia Subsystem) capabilities to guarantee consistent VoLTE and VoWiFi performance. Conduct extensive testing across both domestic and roaming scenarios. Communicate proactively with customers about device compatibility and network changes. Maintain Quality of Service (QoS) during and after the transition through careful planning and monitoring. Ultimately, successful network sunsets depend on ensuring continuity of voice services, managing user migration, and investing in technologies that provide a seamless customer experience. What will this mean for Mobile Virtual Network Operators (MVNOs)? MVNOs face an even steeper challenge as 2G and 3G shutdowns accelerate globally. Without direct control over network infrastructure, MVNOs are highly dependent on host operators’ migration timelines and technical readiness. The example of Dish’s 2021 warning about disruptions from T-Mobile’s CDMA network shutdown illustrates the significant business risks posed by abrupt legacy network closures. To remain competitive, MVNOs must: Upgrade network agreements with host MNOs to ensure continued access to VoLTE and VoWiFi services. Deploy IMS-enabled SIMs and compatible devices, ensuring full interoperability across home and roaming networks. Educate customers on device upgrades and service transitions to minimize churn. Explore new service models (e.g., digital-first or 5G MVNOs) that leverage the improved capabilities of modern networks. Failure to adapt could lead to service degradation, lost customers, and reputational harm, especially in markets where legacy networks have supported key customer segments (e.g., IoT or low-cost prepaid users). In summary, while the 2G/3G shutdowns mark an important milestone in network modernization, both MNOs and MVNOs must strategically manage the migration to protect user experience, brand equity, and long-term competitiveness.

Android 15 vs Android 16: Real-World Benchmarks on the Pixel 8a with SmartViser’s Viser Neo At SmartViser , we prioritise rigorous testing with our Viser Neo automation platform whenever a new Android release arrives. Each upgrade introduces new features, refinements, and potential optimisations—but the real question is: do they make a measurable difference in end-user experience? Using our Viser Neo active test automation platform , we benchmarked Android 15 (“Vanilla Ice Cream”)  against Android 16 (“Baklava”)  on the Google Pixel 8a . Our tests focused on the areas most relevant to users: battery life, gaming, web performance, data throughput, and streaming efficiency . To ensure fairness, both devices were set up under strictly controlled conditions : automatic brightness was disabled, volume levels were aligned, and all battery power-saving features were switched off. This guarantees that results reflect the OS performance itself, not environmental inconsistencies. Feature Differences: Android 15 vs Android 16 Android 15 Highlights Privacy & Security:  Theft Detection Lock, Private Space, stronger authentication. Multitasking:  Partial screen sharing, app pair shortcuts for foldables/tablets. Notifications:  Notification Cooldown to limit repetitive alerts. Media & Developer Tools:  HDR image format support, predictive back gesture, improved app archiving. Android 16 Enhancements Material 3 Expressive UI:  Richer animations, dynamic colors, blur effects. Notifications:  Live Updates, adaptive progress-based alerts. Desktop Multitasking Mode:  Early implementation for tablets and large screens. Security & Privacy:  Advanced Protection, USB port blocking, offline lock, enhanced Health Connect API.

Using Viser Neo , we validated the test environment and recorded the following baseline parameters: Volume (Voice Call):  Both OS versions were set to an average level of 5 . Brightness:  Both maintained the same average brightness setting of 11 , with automatic brightness disabled. Volume (Music):  Both set to the same maximum level of 6 . These consistent settings confirm that differences observed in later benchmarks—whether in battery performance, gaming, web performance, data throughput, or streaming—can be attributed to the OS changes rather than test setup inconsistencies. Web Browsing Performance To evaluate real-world browsing speed, we tested multiple websites and measured Interactive loading time  using Viser Neo. Results showed: Average Loading Time:  Android 15 – 492 ms , Android 16 – 484 ms Minimum Loading Time:  Android 15 – 80 ms , Android 16 – 70 ms Maximum Loading Time:  Android 15 – 4106 ms , Android 16 – 4388 ms Overall, both OS versions delivered near-identical browsing performance , with Android 16 showing a slight advantage in average and minimum loading times . The higher maximum value on Android 16 suggests that occasional page load spikes still occur, likely influenced by network or rendering variations rather than core OS changes. These findings indicate that end users moving from Android 15 to Android 16 are unlikely to notice significant differences in day-to-day browsing speed. Data Performance Using Viser Neo, we benchmarked HTTP download  and upload throughput  to assess raw data performance under controlled conditions. The average results were: Average Download Throughput:  Android 15 – 46.93 Mbps , Android 16 – 42.89 Mbps Average Upload Throughput:  Android 15 – 22.37 Mbps , Android 16 – 21.57 Mbps In both upload and download, Android 15 slightly outperformed Android 16 , though the differences are small enough that most users may not notice in everyday tasks such as web browsing, social media uploads, or streaming. These results could be influenced by subtle differences in network stack behaviour or background OS processes in Android 16. Battery Performance To simulate a typical day of user activity , we ran continuous mixed-use scenarios including gaming, browsing, streaming, file transfers, and idle time. Both Android versions were tested under identical conditions with all power-saving features disabled. Battery Life: Android 15 – 17h 13m 08s Android 16 – 17h 13m 11s The results show no meaningful difference in endurance , with both versions performing almost identically. Current Consumption (per activity): Gaming (WebGL) remained the most demanding activity, averaging around -1350 mA  on both OS versions. Other tasks such as web browsing, video streaming, HTTP upload/download, and local playback showed similar consumption across Android 15 and 16 , confirming stable energy profiles. Battery Temperature: Average temperature on Android 15: 25.9°C Average temperature on Android 16: 26.2°C Both showed consistent thermal management patterns, with Android 16 running fractionally warmer but without significant deviation. Takeaway:  Battery endurance, consumption distribution, and thermal stability remain consistent between Android 15 and 16 . Users upgrading should not expect gains or losses in daily longevity, which highlights the maturity of Google’s power optimization across Android releases. Gaming Performance Gaming remains one of the most demanding use cases, so we tested WebGL-based graphics performance  to measure frames per second (FPS). Average FPS:  Android 15 – 52 FPS , Android 16 – 48 FPS Minimum FPS:  Android 15 – 42 FPS , Android 16 – 35 FPS Maximum FPS:  Android 15 – 62 FPS , Android 16 – 61 FPS While both OS versions delivered a smooth experience, Android 15 consistently achieved slightly higher frame rates  across all measurements. On Android 16, frame rates dipped more significantly at the lower end (minimum FPS), which could result in occasional drops in fluidity during demanding gaming sessions. This suggests that while Android 16 introduces new system-level features and UI improvements, its graphics pipeline may still require further optimisation for high-performance gaming. For most casual users, the difference will be marginal, but heavy gamers may notice Android 15 running a touch smoother under intensive loads. Streaming Performance For video streaming, we measured streaming efficiency , representing how consistently data was delivered and rendered without stalling or buffering. Average Efficiency:  Android 15 – 99.9% , Android 16 – 99.8% Minimum Efficiency:  Both Android 15 and 16 – 99.7% Maximum Efficiency:  Both Android 15 and 16 – 99.9% These near-perfect results show that both OS versions handle video streaming seamlessly , with no meaningful difference between Android 15 and Android 16. End users should expect smooth playback, stable buffering, and no visible degradation when upgrading. Conclusion & Recommendation Our benchmarking of Android 15 vs Android 16  on the Google Pixel 8a , using SmartViser’s Viser Neo test automation , shows that the two operating systems deliver a very similar end-user experience  under controlled lab conditions. Battery Life & Thermal Stability:  Both OS versions lasted over 17 hours , with almost identical current consumption across usage scenarios. Temperature remained stable, with Android 16 only marginally warmer on average. Web Browsing:  Both OS versions were highly comparable, with Android 16 showing a slight edge in average and minimum loading times , though occasional load spikes still occur. Data Performance:  Android 15 recorded slightly higher upload and download throughput , but the difference is small and unlikely to impact real-world user experience. Gaming:  Android 15 achieved higher average and minimum FPS , making it the better performer for intensive gaming. Android 16 is smooth for casual play but may require further optimisation for demanding titles. Streaming Efficiency:  Both versions delivered near-perfect performance (≈100%) , ensuring smooth and reliable video playback. SmartViser’s Take For end users, upgrading to Android 16 will not drastically change performance  in key areas like battery life, browsing, streaming, or daily app usage. The main improvements of Android 16 lie in new features, UI refinements, and enhanced security tools  rather than raw performance gains. If you are a heavy gamer , Android 15 may still feel marginally smoother, but most other users will not notice a difference. If you value security, privacy, and new functionality , Android 16 is the clear choice, offering features like Advanced Protection, improved multitasking, and Material 3 UI updates. Ultimately, the upgrade decision comes down to whether users prioritise stability and slightly better gaming on Android 15 , or new features and improved system-level protections on Android 16 . At SmartViser, our role is to ensure these insights are backed by real measurements under repeatable conditions , helping the industry and end-users alike make informed choices.
