The battery life of your myFirst Fone S4 depends on how the watch is used, as well as network conditions, signal strength, tracking settings, and other features.
If you feel that your battery is draining faster than expected, the information below explains what battery life you can expect, what can cause faster battery consumption, and what you can do to extend battery life.
How long should the myFirst Fone S4 battery last?
The myFirst Fone S4 is advertised with up to 5 days of standby time and up to 2 days of typical use.
These figures are based on internal laboratory testing under defined conditions. Actual battery life may vary depending on your child's usage, network environment, signal strength, feature settings, and other factors.
Up to 5 days in standby
The up to 5-day standby time is based on internal laboratory testing under very limited-use conditions.
During the standby test, the smartwatch was:
Left completely untouched
Kept with the screen off
Not used for voice or video calls
Not used for GPS tracking
Not sending or receiving messages
Not interacting with applications
Important: Standby time is different from normal daily use. Using features such as GPS tracking, calls, messaging, camera, video, or other applications will consume more battery power.
Up to 2 days with typical use
The up to 2-day typical-use figure is based on a defined daily usage model from internal laboratory testing.
The test included the following activities each day:
14.3 hours of screen-off standby
60 minutes of Tracking Mode, with the location updated every 5 minutes
30 minutes of Class Mode
3 voice calls, 30 seconds each
1 video call, 60 seconds
Receiving and playing 7 voice messages
Sending 7 voice messages, 15 seconds each
Using the camera 3 times
Viewing the gallery 3 times, including photos and short videos
6 manual location updates from the myFirstCircle app
3 heart rate measurements
Turning Wi-Fi on/off 6 times
These conditions represent a controlled laboratory testing scenario. Your actual battery life may be shorter or longer depending on how your child uses the watch.
How can I extend the battery life?
If you find that your myFirst Fone S4 battery is draining faster than expected, you may try the following steps.
1. Adjust Screen Brightness
Set the brightness of the myFirst Fone S4 to low or auto mode.
2. Optimize GPS Location Updates
Set the GPS location update (Tracking Mode) on the myFirstCircle app to update every 1 hour to reduce
power consumption. You could set it to a shorter tracking update time when you need to know the exact location of your child eg. while traveling to school or returning from school.
3. Turn off Auto Tracking
Turn off auto tracking in tracking mode to monitor and reduce battery drainage.
4. Proper Charging
Ensure the watch is charged for 1-1.5 hours and avoid overnight charging.
5. Keep Watch Software Updated
Make sure the watch software is up to date.
6. Turn On Low Power Mode
You can turn on low power mode in your watch settings to conserve more battery power for the watch.
By following these steps, you can maximize the battery life of your myFirst Fone S4 and ensure it functions optimally throughout the day.
What should I expect from the battery in everyday use?
Battery consumption will not be the same throughout the day. A watch that is mostly left untouched with the screen off will generally consume less power than a watch that is frequently used for GPS tracking, calls, messaging, camera use, video, or other power-intensive features.
Daily charging may still be necessary depending on your child's usage, particularly when the watch is frequently used for tracking, calls, messaging, or other power-intensive features.
The laboratory figures are provided as a reference and do not guarantee a specific battery duration for every user.
Battery Life Disclaimer
The up to 5-day standby and up to 2-day typical-use figures are based on internal laboratory testing under defined conditions.
Actual battery life may vary depending on:
Network environment
Signal strength
Tracking frequency
Feature settings
Call duration
Frequency of GPS usage
Individual usage habits
The 5-day standby figure represents very limited-use conditions, while the 2-day typical-use figure represents a defined daily usage model. Neither figure should be considered a guarantee of actual battery life for every user.
