New Yi 2 4K Action Camera Review – The Upgraded Version of Yi

Today I am reviewing the upgraded version of Yi action camera, the new Yi II 4K. Yi has enhanced many aspects of original Yi in the new Yi II, not only in the technical aspects but also in terms of looking. The price of Yi II is also quite increased from its predecessor. So here I will try to highlight all the specs of new Yi II comparing with the previous Yi and will see if the jump in the price is justified or not.

The specification of Yi II 4K action camera really looks much improved. Let’s see all of it.


Xiaomi Yi II - 1

The most important upgraded of new Yi II 4K is the image sensor.  It is now using a faster IMX377 12-megapixel image sensor with a sensor size of 1/2.3 inch. It is capable of shooting video in 4K ultra HD resolution at 30 frames per second. Comparing to the 1080P full HD of Yi, it is really a great improvement and may be the main reason to upgrade.

The lens quality is also very much improved especially the aperture. The lens is built in a 7 layers optical glass with a big aperture of F/2.8 and a great wide angle of 155 degrees. This will surely improve your landscape photo and videography and will also improve the video and image quality in low light.

The battery capacity of new Yi II 4K is 1400mAh which is very good for any action camera. The battery can be charged with the help of USB from any PC or by using any USB charging adapter. You will get approximately 120 minutes of total working time at a video recording of 4K (30fps) and it will give around 8 hours of standby time. So in total the battery given is very much powerful and it is a large capacitive battery as well. The working time of Yi is 80 minutes at a video recording of 1080P (60fps). So you can compare easily how efficient the new battery will be. The only drawback is, in the case of Yi the battery is removable. So, you can carry spare batteries to use. But in Yi II 4K the battery is non-removable. Although one single charge can give you a great recording life, in my opinion, removable battery is always better.

LCD Display:

One of the big compromises you can find in the older Yi is the unavailability of LCD display screen. This is surely done to reduce the product cost. But this is not the case for Yi II 4K. Here you will get a decent 2.19 inch LCD display with a resolution of 640 x 360 pixels and a pixel density of 330PPI. The LCD screen also supports touch. So, it is also a great improvement in Yi II 4K.

Other improvements & key features:

The Yi II 4K supports a dual-band WiFi that can give you a faster download speed. It also upgrades the chipset to the latest version of Ambarella A9SE75. This will surely improve the processing speed of the camera. It also supports a micro SD card up to 64 GB. It is recommended to use a card of class 10 or higher. This will ensure to produce a great quality video output.

In this action camera, there is nine picture taking modes: Usual picture, Timer photo, Continuous shot, Usual video, Time-lapse video, Slow-motion video, Time-lapse image, Loop video and Video + Time-lapse picture. With the help of this action camera, some mind-blowing videos can be captured. For an example, you can record flower opening videos, ice, and snow melting videos, the sun rising videos, and the sun setting videos, etc.

You can use this camera under a 20 degree to 85 degree Celsius temperature. That means this camera is compatible and suitable to use even in a very hot and humid area. It has a 6 axis anti-shake feature. This will definitely help you to record good quality pictures and videos even when you are doing surfing, parachuting, skating, rafting or where the vibration on the camera is out of your control etc.
