Using a non-Fossil charging cable and puck. Please make sure the charging cable
and puck that came with your watch is used. 3rd party charging cables cannot be
guaranteed to provide fast charging.
My watch is not charging when attached to the charger.
Make sure that the watch charging/data rings on the bottom of the watch are clean
and free of contaminants.
Check the four silver pins on the charger that connect to the watch. Make sure they
are not bent, broken or damaged in some other way.
If available, try using another charger (wall wart, computer port, etc) connected to the
cable.
5.11 CAN I USE DIFFERENT GENERATION CHARGERS ON MY WATCH?
For WearOS watches with charging rings on the watch case-back, any of the
charging cables with the circular charging pucks (2 or 4 pins) can be used to charge
the watch but performance may vary.
To note, the charging rings on our WearOS watch case-backs consist of either 2
concentric rings or 2 concentric rings that are split, creating 4 separate electric
contacts. The WearOS watches with split rings, 4-pin case-backs, can charge at the
higher and faster charge rates when paired with a 4-pin charging puck. All WearOS
watches with charging rings will always charge at the slower rate when using the 2-
pin charging pucks. Watches with 2 concentric rings on the case back (not split) will
also charge at the slower rate even when paired with a 4-pin charging puck.
Which charger (wall adapter) is compatible with my watch?
Any laptop USB port or UL approved USB wall adapter will charge your watch
5.12 AS A DEVELOPER, CAN I ACCESS YOUR WEAROS WATCHES VIA USB?
If you have one of our WearOS watches with the split rings (4-pin) case-backs and a
4-pin charging puck, you can connect this to your computer using developer tools
and get developer access to the system so you can side-load and test your apps.
For best data connectivity, make sure that the cable wire is aligned with the crown
button. This position provides a more reliable data connection for HS-USB data.
Also make sure that the watch charging/data rings on the bottom of the watch are
clean and free of contaminants. If you have connection issues, try disconnecting and
reconnecting the charger to the watch with the cable aligned with the crown button.
6. SYNCING & TROUBLESHOOTING
6.1 MY BATTERY WON’T CHARGE PAST A CERTAIN PERCENTAGE. HOW CAN I FIX
THIS?
Let the smartwatch run out of battery completely. Charge your smartwatch until the
screen indicates charging is complete. After the watch is at 100% battery, press and
hold the power button until the device restarts.
