What Our Latest Customer

is Saying...


Wiko Power U20



"We as manufacturers of Smartphones aim to deliver the best experience for our users. Developing newer Smartphones requires a large amount of time and expenditure to be competitive and visible in a very crowded and fast-moving market. The Battery Life of a Smartphone is absolutely critical to users and their daily productivity. Our R&D has put a lot of effort to provide a superior battery life performance for our end users.

SmartViser was chosen for this project as they offered superior knowledge on Smartphone Battery Life and Performance, critical to us when considering future Smartphones. The SmartViser testing was impressive and performed in very strict testing conditions.  Our Smartphone passed very rigorous testing protocols and we are extremely pleased with our ViserMark Label as a result of the overall tests.

Thanks to ViserMark we were able to clearly communicate our leadership in best battery life performance. The ViserMark score has a direct impact to our sales and end user experience.”
