What better way to start 2023 - A New ViserMark Label! It has been a very busy year at ViserMark and thank you to all of you who got in touch with feedback on how the labels have helped you understand the battery performance and which device to choose next. We do understand there is a plethora of technical information that often makes it difficult to grasp exactly how this will impact “you” with your day-to-day smartphone usage. For buyers who are looking to purchase a smartphone, the only information available to them is either the battery capacity in milliamp hours or more commonly abbreviated mAh or some endurance score that is based on a very specific usage like standby or talk time. We have also seen over the years that each manufacturer and media have their own way of assessing battery performance considering different criteria and, on some occasions, tests are performed in perfect mobile network conditions which none of us experience. But how long this device will last with real-life usage or how long it will charge? ViserMark was the first label in the world to introduce a clear metric on the Day of Use, meaning how long will this device last tested over the day and night with real-life user activities. We have now further improved the label to give you additional information on how long the device will last in hours for clearer information. Look for the new label in our reviews from January 2023. It is true that mobile phone battery technology has considerably evolved over the years and is continuing to evolve. We still see some manufacturers pursuing to make their mobile phones last longer, simply by increasing the battery life size. The larger battery will use more natural resources and the frequent charging and discharging will further deteriorate the battery. We all now understand that we need to ensure the Smartphone manufacturing industry uses more sustainable methods and is creating products that have minimal impact on the environment. ViserMark was again the first label in the world to create a label that showed the battery energy efficiency of the device. It is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being the least and 5 being the most power efficient. This year following the feedback we have received and our own involvement in various projects that looked to create policies on Energy Efficiency we will be introducing a new label in 2023 that will show the Annual Energy Consumption measured in kWh. For the first time, end-users will be able to see an objective benchmark across all devices on the expected annual electricity consumption their device is expected to make. We are very keen to hear your feedback regarding these new changes. Make sure you follow us on Social Media and receive our Newsletters to stay up to date with all our latest insights.

Here's what we discovered... Our SmartViser team (the test automation technology that powers ViserMark) has visited IFA in Berlin this year and has brought us the key highlights from the event. IFA is a trade show mainly for consumer electronics and home appliances. After a 2 years gap due to the Covid Pandemic, the show opened its doors on the 2nd of September. Organisers said more than 161,000 visitors attend this year’s event. So what were the main highlights? SmartViser at IFA 2022 Our team of experts were at IFA in Berlin discussing the new proposal by the EU on an energy efficiency Index rating for smartphone batteries. Under the new proposal, the Ecodesign and energy labels will aim to make smartphones and tablets more sustainable. According to Fraunhofer IZM “The new energy label for smartphones and tablets will not only display the familiar energy efficiency labels. For the first time, it will include the new EU-wide repairability rating and more information about reliability with details about how long the battery can be expected to last and how the device would fare when exposed to dust, submerged in water, or accidentally dropped” See below the proposal for the new label: Asus at IFA 2022 Following the recent smartphone launches with flexible screens, it was good to see the Zenbook 17-Fold OLED. The price is expected to be around $3,499. The technology was very impressive and a magnetically attached keyboard can also be used. The total weight is 1.5kg and the keyboard 1.8kg. Other features include Intel Core i7-1250U, 16GB of RAM, 1TB of storage, 75 Wh of battery and two Thunderbolt 4 ports. Honor at IFA 2022 Honor announced a brand-new device during the IFA show.

The lab team at ViserMark has been running battery life tests for some of the newly released smartphones this year. As many more Android smartphones have 5G options we wanted to take a closer look at the connectivity, performance and battery life of the Samsung Galaxy S21 5G and the Vivo Y72 5G. The Samsung Galaxy S21 5G was revealed in January this year as the flagship for the Samsung S-series. For testing purposes, this time our Samsung Galaxy S21 5G is Phantom Violet, (we think it is quite a refreshing colour), also it is still a compact smartphone available within the flagship tier (€700 +) of the Visermark Smartphone Tiers. Having many features including, an AMOLED display with adaptive refresh rate handling, enhanced selfie performance and a 4000mAh battery with 25W charging. Keep in mind, that there is no charger or headphones included with this package. The Vivo Y72 5G is the latest smartphone to be released from Vivo. Being ranked as mid tier (€200-€499) smartphone, it also showcases many features including that of a MediaTek’s Dimensity 700 5G chipset and a powerful 5000 mAh battery with 8W charging. It is an attractive smartphone for the price, being around €400 less expensive than the high-end Samsung Galaxy S21 5G. It will provide you with 5G plus all the features you come to expect from today’s smartphones. The most significant frustration mentioned by end-users about their current smartphone is poor battery. Battery performance is a top reason for selecting a new smartphone. 5G has transformed smartphone capabilities with improved connectivity to other devices, such as a household appliance, a car or simply a watch. It also allows for the streaming of TV, music, films etc. with much faster connection speeds – often 20 times faster than 4G. Our short video - Are You 5G Ready? covers the capabilities, but there are also other factors worth considering about 5G... Speed Bandwidth is a key benefit to this technology, being able to handle around a thousand times more data at once than 4G. Coverage 5G range is not as good as 4G coverage. Despite nationwide networks being already built with more on the way, speeds still vary quite widely. Battery Life 5G smartphones are likely to be much more demanding in terms of power and data than 4G smartphone equivalents. With battery life being a key consideration when buying a new smartphone, is 5G more likely to drain your battery? Well, it is time to find out! Although both smartphones are tempting, which one offers the best battery life performance on 4G or 5G? To answer this question, we took the Samsung Galaxy S21 5G and Vivo Y72 5G smartphones to our independent testing lab, where viSer test automation measures and validates key areas of an end user’s experience using our highly specialised, state-of-the-art lab environment. Our SmartViser technology experts use their years of experience to simulate real day life general usage. Testing Scope: Network Conditions: 4G & 5G with similar radio network conditions (Between -80dbm and -90dbm) Mobile Network: Orange France Location of Testing: Rennes France Use Cases: Web Browsing Youtube Social Media (Instagram) With the Vivo Y72 5G having a battery of 5000 mAh capacity, the bigger battery of the two, since the Samsung Galaxy S21 5G features a slightly lower battery capacity of 4000 mAh. The ratings indicated in our results show in minutes the duration to drain 5% of the battery capacity for the Samsung Galaxy S21 5G or the Vivo Y72 5G. Orange was selected as the network provider for both 4G and 5G, offering similar radio conditions during testing. Finally, 3 user cases were selected, specifically focussing on common daily life activities of an end-user when consuming data. Outcomes Below reflect the test results for the Samsung Galaxy S21 5G: Below reflect the test results for the Vivo Y72 5G: To learn more about our automated testing protocol click here Both smartphones when using 5G, generally display over draining slightly more. However, the test results show improved performance for streaming. Samsung Galaxy S21 5G So the Samsung Galaxy S21 5G, as we already know has a smaller battery life than the Vivo Y72 5G, however, when testing on 4G and 5G within good signal strength and comparable quality conditions, the Samsung Galaxy offers similar battery life. Vivo Y72 5G Also, the Vivo Y72, with good signal strength and comparable quality conditions, offers a similar level of battery life. If you are an early adopter of 5G then it should not have a serious impact on battery life. As theoretically, radio coverage is far from wide and radio condition will remain at a lower strength and for instance, indoor coverage is weaker. At ViserMark we have measured the impact of weaker 5G radio condition on battery life. As you can see below impact is rather important. Conclusion From our findings, there is not a large difference between the Samsung Galaxy S21 5G and the Vivo Y72 5G when comparing 4G vs 5G connectivity. That said, the Samsung Galaxy S21 5G offers good performance, a sharp display and a battery life of around one day. It's also worth pointing out that the Vivo Y72 5G certainty delivers a slight performance boost with its 5000 mAh battery. Your choice to keep your phone connectivity on 5G will depend on your usage. 4G is still perfect for browsing and using social apps, indeed we have not noticed any significant changes in performance for the specific everyday user activities tested. The 4G coverage is in most locations much better than 5G and using 4G more will help to limit battery drainage. If you are heavily consuming media or a business user higher data rate may boost your experience while you will need to compromise with lower battery life. This was our very first dedicated 5G battery life and performance testing, we will continue further analysis on 4G vs 5G connectivity and the impact on the battery life and performance of a smartphone. We will aim to replicate more typical end-user usage testing incorporating 5G coverage. Further reports and testing results will be shared in the coming months with performance on specific devices, chipsets, and Network Operators.
