Troubleshooting a Garmin Watch that will not Charge or Power On  

It is recommended to charge the battery for an hour, even if the display does not show the device 
charging, before determining that the battery is no longer functioning as intended. 

For devices that are having power issues, such as not powering on/off or not taking a charge, a 
soft reset can be performed to return the watch to a normal state. A soft reset does not remove 
any information from the watch. This reset is most effective when the device is connected to 
a computer. 

 

Performing a Soft Reset 

1.

 

Connect the device to a computer via charging clip 

2.

 

Press and hold POWER/LIGHT button for 25 seconds or until device powers off 

3.

 

Press POWER/LIGHT to power unit back on 

4.

 

Charge battery to 100% 

5.

 

Update the device's software with 

Garmin Express

See related content for installation 

instructions. 

The device will now turn on and charge properly. 

How to Improve the Garmin fenix 5 and fenix 5s Battery Life  

If you are charging your Garmin fenix more frequent than expected, it could be due to the 
amount of usage or settings being used. Below is a list of functions that could cause the battery 
to drain faster than anticipated, for instructions on enabling or disabling these, visit the 
"

Customizing Your Device

" section in the owner's manual.  

NOTE:

 It is important that before you address some of the functions that affected battery life, 

that you first make sure your watch is up to date:

Series Watch

 

Some of the functions are redundant, for example; steps and activities are uploaded both through 
WiFi and the Bluetooth connection to the Garmin Connect Mobile application. If using the 
Garmin Connect Mobile app continuously, it may be a good idea to turn off the Auto Upload 
setting to help conserve battery power. The Storm Alert function of the Barometer when a smart 
phone updates local weather is another redundant battery drain. 

If battery drain still continues after making some settings changes, try returning the watch to 
factory defaults and seeing how long the battery lasts on a full charge without pairing it to 
smartphone again. If the battery lasts like it used to, then the battery drain would be the result of 
the choice of customized settings on the watch, or Bluetooth connected features.
