How long is the battery life of DEBUT devices? How many GNSS fixes can it collect?

The battery life of a device refers to the duration a fully charged device can operate before it pauses due to the battery level dropping below the operational threshold. This duration is influenced by several factors:

1. Battery capacity
   The battery capacity varies in different devices. For example, the battery capacity of MINI is 30 mAh, the battery capacity of LEGO is 210 mAh, and the battery capacity of BADGE is 19000 mAh. The battery capacity of other customized products is also different. Different battery capacity will have an important impact on the battery life.

2. Efficiency of solar charging
   In clear summer daytime, it usutally takes 1 to 2 days to fully charge the battery for most of the devices if the solar panel of the device is exposed to direct sunlight. While in winter or cloudy days, or the device is in an environment where it cannot be exposed to direct sunlight, it may not be able to charge the battery effectively. At this time, you need to lower the frequency of transmission and data collection to maintain the power balance, and wait for the light condition to improve.

3. Power consumption difference
   Different device functions require varying levels of power consumption. For instance, tasks like environmental data and ODBA collection typically demand minimal power, whereas GNSS positioning and data transmission rank among the most energy-intensive functions.
   Moreover, the power consumption of a specific function can be influenced by several factors. Take GNSS positioning as an example: its power usage is affected by the GNSS time consumption. Generally, the longer the positioning process takes, the greater the power consumption. This positioning time varies depending on different settings and environmental conditions. Typically, it falls within the range of 30 to 60 seconds after deployment. However, under BOOST mode activation, GNSS positioning can be completed in as little as 2 to 5 seconds. Conversely, in unfavorable GNSS environments, it may extend to 90 seconds or more.
   During test, scenarios such as being indoors without a clear sky view can significantly prolong the positioning process. In such cases, it's not uncommon for the positioning time to reach up to 150 seconds without achieving successful results.

As a result, it is difficult to have an accurate estimation of battery life without an comprehensive understanding of the living environment and habits of the specific animal.

You can refer to the following case as a benchmark. The prerequisite is no charging and the device is in an open area without liquid and electromagnetic interference.

1. BADGE C4 4G, 9000 mAh, GNSS 1h/ENV 1h/ODBA 10min/Transmission 8h, GNSS consumption time 30 ~ 90 s, battery life 290 ~ 726 days, i.e., 6960 ~ 17424 GNSS fixes.

2. LEGO 4G, 210 mAh, GNSS 1h/ENV 1h/ODBA 10min/Transmission 1day, GNSS consumption time 30 ~ 90 s, battery life 5 ~ 13 days, i.e., 120 ~ 312 GNSS fixes.

3. MINI 4G, 30 mAh, GNSS 1h/ENV 1h/ODBA 10min/Transmission 1day, GNSS consumption time 30 ~ 90 s, battery life 1 ~ 2 days, i.e., 18 ~ 46 GNSS fixes.

4. ULTRA 5G, 15 mAh, GNSS 6h/ENV 1h/ODBA 10min/Transmission 1day, GNSS consumption time 30 ~ 90 s, battery life 2 days, i.e., 6 ~ 13 GNSS fixes.
