Earlier today, we reported that Xiaomi was going to soon announce the new generation Xiaomi Yi 4K Action Camera 2. Then, we got our hands on a test doc of the Yi Camera’s battery life and it showed that the device could record 4K videos at 30 fps for nearly 120 minutes continuously. Now, we have got our hands on another document of the new Yi camera generation, this time testing the data transfer speeds, from the camera to the connected smartphone via its Wi-Fi connection.
So, the Wi-Fi was set at a random channel and the distance between the Yi 4K Action Camera 2 and the connected smartphone was 1 meter. The test was simple. The user first recorded a video of around 500MB on the new camera. Then he downloaded and installed the companion camera app onto his phone and connected the camera via Wi-Fi. There were two phones used for this test, a Xiaomi Mi Note and an iPhone 6S Plus. Further for comparison, the GoPro Hero 4 Black edition was also tested following the same process.
So, the results of the test are as follows:
| Model number | band (channel) | Phone | download file size（MB） | download time（s） | download rate（MB/s） |

So, there are four samples being tested out here of the new Yi Action camera. Plus, at the end, you can find the GoPro Hero 4 Black for comparison. It looks like the new Yi Camera generation manages to transfer the video at double the speed as compared to the GoPro model.
We hope to get more details about the new Yi camera from our source, including some camera samples. So, stay tuned to gizmochina in the coming days.
