Zeblaze Thor 4 Dual Smartwatch

The Zeblaze Thor 4 dual is a standalone smartwatch running a full, but customized, Android 7.11 operating system. Users will have full access to the Google Play Store and the functions of a smartphone inside of a smartwatch. It has a 1.4″ S-AMOLED display at a resolution of 400*400.

The Thor 4 is the predecessor to the Zeblaze Thor 5 Dual which has a completely different design. Some may prefer Thor 4’s design over Thor 5 because of its classic design.

Interestingly, the “Dual” in both the Thor 4 and Thor 5 have two different meanings. With the Thor 4, there are dual 5MP cameras, and the Thor 5 has dual processors.

The Zeblaze Thor 4 Dual has a 5MP front-facing camera at the top of the watch where you would expect it. This makes the camera more useful for video calling. It also has a 5MP side camera which you may not use very often, but it is there. This means that the Thor 4 has two cameras and the Thor 5 Dual has one.

On the back, you’ll find the sim card slot, heart rate monitor, and the four-pin connection to charge the smartwatch and transfer data. Also, you’ll find the physical power and back buttons on the right side of the watch, instead of the left side like the Thor 5.


The Thor 4 Dual runs the MediaTek 6739 processor running at 1.25GHz with a 530mAH battery. This isn’t the MediaTek 6739 + NRF52840 dual processing unit on the Thor 5 which gives the watch two operating modes. However, the battery on the Thor 5 is only 548mAH and it also runs at 1.25GHz so you won’t see much of a difference in performance.

The standby time of the Thor 4 is listed at 2 days and battery life will ultimately depend on how you use and optimize it. Since it’s supposed to be a standalone device and relies heavily on 4G, you should anticipate one and a half days of actual usage. That doesn’t sound like a long time but considering you can install anything from the Play Store, it’s decent.


The Zeblaze Thor 4 Dual comes with 1GB of ram and 16GB of internal storage. These resources should be enough for most users, but keep in mind that the Thor 5 has 2GB of ram and 16GB of internal storage. Ideally, we need to get to a place where all Android Smartwatches have 3GB of ram and 32GB of storage like the Kospet Optimus Pro and Kospet Hope.

Navigation is quite fluid, and anyone that has used Android should feel comfortable using the interface after some time. Even though the watch is powered by Android 7.1.1, it’s a modified version of the OS with its own widgets and navigation panels.

Finally, there is no waterproof rating listed for the Thor 4 Dual. Typically, these smartwatches have a “Life Waterproof” rating which is basically IP67 rating. You should be ok with rain and sweat, but IP67 isn’t suitable for high-velocity water activities.


The Zeblaze Thor 4 Dual comes with a 4G LTE radio unlocked for any carrier. You can check the specs below to see if your area supports the bands. In the United States, T-mobile, AT&T, and other GSM carriers work fine. Bluetooth 4.0 is available for using headphones or sending and receive files. However, there is no Bluetooth calling with any Android 7.1.1 devices due to Google restrictions.

GPS works excellent with applications like Google Maps and Uber but not with the built-in fitness applications provided by Zeblaze.

Fitness Applications

Essentially, these Android smartwatches come with their own fitness applications with activities such as Outdoor Running, Walking, Indoor Running, Bike Riding, and a few others. If you want to track your distance using GPS, the watch doesn’t have that functionality even though GPS is on board, it uses the pedometer instead.

This is annoying because all manufacturers know we want GPS tracking our activities. The problem isn’t that the applications use the pedometer, the problem is that you can’t change the widgets where the inaccurate data is shown. This isn’t good for fitness enthusiasts.

If you want GPS tracking on the Thor 4, you’ll need to wait until they push an update to patch it or use Google Fit.


Typically you can get some help from the manufacturer when you have a hardware or software-related issue. However, you may find the Full Android Watch forum helpful for tweaks, tricks, or to see what others in the community are doing with their full android smartwatches.
