Based on our evaluation, if the Mictrack MT710 runs in MODE 3 with a reporting interval of 24 hours, it can operate for 12 months. To verify this, we have taken one MT710 and placed it in our office for a long battery life test. We will continue to monitor the test results. Below are the test details: 1. MT710 Test record form: https://docs.google.com/spreadsheets/d/1q5aXwvett89bCvQyUxH63d7-h8vroowI4WqcY24nMZs 2. MT710 Test screenshot on our server : https://drive.google.com/drive/folders/1_kjfKoSvvaSnLjwAHOeB--XNs2orQDOR 3. The Config parameter the test device: Device Model :MT710 Network and band China Mobile NB-IoT B8 Working Mode: Mode 3 Report interval: 24 hours Battery: Rechargeable 3.7V 650mAh **_Let's monitor the real battery life. We will keep the updates every month in our forum._**

Until today, it has run for 60 days, and the battery voltage is 3.997V (88.56%)

@"Garin"#p48 OK please let me know. Thanks

@"halloonkel"#p50 Yes, we will point to your server to test again today.

@"Garin"#p51 Hello, thanks I will have a look on the working time.

Hi, what is the battery working time when the device is in mode 1 and interval is 60 seconds?
Thanks

Garin

halloonkel In our local test in MODE 1 with 60 seconds interval, the battery life up to 39 hours. Of course, in our test environment, both the GPS and network signals are good.

Hello Garin, as you see in the picture, the device run around 13 hours. Then the battery was empty. You write it will run for 39 hours. Was you test device defect. Can we make a test again?

halloonkel Let me check the config and get back to you next week. To improve battery life, we need to do more config.

halloonkel

Garin OK please let me know. Thanks

Hello Garin, can we make a test again? Thanks

Garin

halloonkel Yes, we will point to your server to test again today.

Garin Hello, thanks I will have a look on the working time.

Also we used the low power analyzer and ran it for one hour to measure the average power consumption in MODE 1 with
60 seconds interval. In the real test, the network, GPS signal and temperature are dynamic and can slightly affect power consumption.

Hello Garin, so the result this time was a battery working time about 19 hours.
Is this the maximum?

Garin

halloonkel It started on 2024/8/1 8:41:40 and ended on 2024/8/2 18:23:23, totaling 33.74 hours. During the test, we found that sometimes the device failed to report to the server and needed to resend (we not found this issue on our local server), which slightly increased power consumption.

In the end, the final battery life was 308 days, but we found that debug mode was enabled during the test, causing extra power consumption. Anyway, we’ll conduct a new test with updated hardware (reducing power consumption to 1.2 µA in deep sleep, down from 2.2 µA) and disable debug mode. Once the new test is ready, we’ll share a new post here.
