Battery drain is a critical concern for any mechanical device due to manufacturing flaws, technical problems, or other problems. It is vitally crucial for you as a user of Garmin Speed Sensor to get your Speed Sensor in full. If the Speed Sensor displays a low battery or stops operating after just a few hours of inserting a fresh battery, it implies that the batteries are dead due to the high-power drain.

Speed Sensor has a magnetometer similar to the accelerometer that measures all three-dimensional elements of the magnet environment. The magnetometer detects the spinning of a wheel in the surrounding earth’s magnetic field. Instead of a poor magnetometer connection, there may be no severe problem. It may appear helpful to change the magnetometer. The purchase of a new speed sensor is very simple and efficient instead of changing the magnetometer.

Reasons why the Garmin speed sensor battery may drain

1. All-time Bluetooth activity

The device will always be connected to a speedometer by Bluetooth. If the speed sensor is not in use and the devices are connected, then the battery may easily drain. Leaving the connectivity on when not in use is a major mistake. Always ensure you turn off all the connections when you are done using them.

2. The GPS tracking

This feature is nowadays very essential compared to Bluetooth. GPS can considerably contribute to a large battery drain, and hence GPS monitoring is only active during operation or navigation. We strongly recommend that you do not turn it on until you need it.

3. Bad quality of the battery

Bad Quality Of The Battery

For the Garmin Speed Sensor, one battery is utilized. The LED glows red to indicate a low battery level after two rotations. If the sensor’s battery drains fast, the problem could, however, be your battery’s quality. The sensor is usually located at the back. An alternative brand should be considered.

4. Poor battery connection

The battery may drain due to a bad connection. It mostly occurs when the sensor is rotating, misplacing the battery. You only need to position the battery in its right position to solve this happening.

5. A dead cadence sensor

Cadence Sensor

In the case of a dead Cadence sensor, Duo trap sensors can be changed. You can possibly hear it ticking, but there is no light, and it can’t catch up to 510.

6. Moisture

Your speed sensor might be drowned or accidentally got wet. This will make it drain at a high rate. To solve this, you need to dry it up by using a hairdryer or placing it in a rice bag. This will help dry up the moisture.

7. Different settings of the system

Sometimes the battery is drained faster than usual owing to some defective settings or just a change of the settings. Try to reset your sensor and see whether the default settings are better off.

8. An old software version

Sometimes speed sensors lack the capability of work they may need because of the old version of the software. Once enabled, if the sensor battery does not respond positively and still drains, Try the new program and update them.

Battery Life Maximization

1. Turn on the Battery Saver Mode – Battery-saving mode automatically changes the settings to extend the life of the battery for longer journeys. The screen is turned off during the activity. To wake up, you can activate automated alarms and tap the screen. GPS tracking points, as well as sensor data, are stored less often by Battery Save mode. The precision of data is decreased in speed, distance, and track.

2. Reduce the brightness of lighting or shorter time off – (Display Settings). Your screen is among the most energy-efficient components while understanding how to regulate its use significantly reduces your energy use. The more you check the screen for updates, the more your battery drains off.

 You have to restrict the length of time you use on your screen. Most phones automatically change brightness depending on the existing illumination, so you might have to do so each time you go to the screen. Nevertheless, it’s worth it if you receive an extra phone time of even a few minutes.

Battery Life Maximization

3. Select the interval of intelligent recording (Data Recording Settings) – Smartphone battery use statistics show the most powerful apps. You may also verify which applications drain the most power on the background when actively utilizing them. You’ll see that most battery-powered applications have the highest display time. That’s sensible, and there’s nothing you can do until you modify your choice and use it. However, you may modify how you utilize apps in the background which consume energy.

4. Turn on the car sleep characteristic (Using Auto Sleep) – The Wake-Up Interval is distinctly assigned by each hub and is primarily handled behind the scenes, making it hard to verify or alter.

The battery life is significantly decreased if the gadget wakes up every minute and delivers a sensor read. Usually, the device battery level is indicated on the Wake-Up Interval.

5. Turn the wireless phone function off (Phone Settings) – Apps or even an operating system are updated, and content download/streaming requires considerable electricity. It’s fantastic to listen to the music on iPhone users using Bluetooth rather than Airplay. Airplay rather than Bluetooth consumes more energy. Another option can allow you to preserve more power if you can utilize earbuds.

6. Choose the setting for GPS – Choose the best setting for GPS in which it will not consume a lot of power. GPS takes a lot more battery capacity; however, even GPS services are low in power consumption when properly controlled. If feasible, decrease display time by finding a location, for example, when using GPS. Make sure you completely examine and disable other apps on your memory that use location services and think about saving critical applications, for example, the ones your family tracks you.

Email and location applications can constantly sync, examine with new notifications verifying servers. Choose your main travel applications wisely and limit the background information for the others. Delete screen widgets such as stock applications or weather applications that offer unneeded power-saver mode, which inhibits background data consumption in some phones.

7. Disable all the battery-saving apps – It appears the opposite, but the deactivation of any power-saving applications will retain the route with GPS application in its manner of design. Ensure that the options Battery Saver is OFF.

8. Remove sensors you don’t use anymore – If the sensor is not in use anymore, it is better to remove it to avoid unnecessary use of the battery when you forget to turn the connectivity off.


The drainage of the battery is rather surprising. It is very deceptive not to get the information you need on time. Before buying any Garmin Speed Sensor Battery, you should always consider some of its operations and conditions. It would help if you were very careful with speed sensors. Together with this check, you may also grasp this crucial aspect better.

The above steps will help to solve the problem of battery drainage if such a problem exists. If not, the sensor must be replaced and a new one purchased. Turn off mobile data and Wi-Fi in places that are not stable because the telephone searches for a signal using a lot of battery. Do not expose your telephone to excessively warm or cold conditions that impact your battery life.
