WOW, was going crazy with battery and synching. Did the reboot and all is working again.

I had that problem when the watch was brand new. It would lose substantial power within hours in minimal watch mode. I discharged it completely, recharged fully (topping it off for good measure) and now it works fine.

I’ve read that the battery life indicator may sometimes be incorrect too, requiring a reboot or full discharge/charge cycle. You never know if the battery is actually draining or if the problem is with the charge sensor.

Here is an update: my Felix 3 battery discharged daily for over 2 months. Even when Bluetooth and wifi were disabled on the iPhone and the watch the drain continued. Totally reset the watch and lost all my data from last year and that did not fix the battery drain problem. About a week ago I applied an update to Garmin Connect, the phone app, and guess what, the battery has stopped discharging fast. It is back to normal …… but who knows how long this will last.

I’ve recently been experiencing this battery drain problem too.

I also seem to have this problem where my watch screen constantly switches from the usual time screen to compass screen. It’s very annoying. Does anyone else have the same problem?

I also had this problem after 8.20 update. I turned off bluetooth and wi-fi and I restarted it. Now looks fine.

Thx Jonathan, auto upload is turned off and I’ve never connected to wifi. I’m using the watch to count steps and navigate hikes with the gps feature. I turned off the Bluetooth on the watch and left it off but the battery drain continues. Thanks for the suggestion though … much appreciated!

In reply to Keith. Check that the wifi auto upload is turned off. Mine is usually but I was having the same battery drain issues and sorted through all the settings and found this. Not sure if this a fix yet but I'm assuming that was what my problem was as the watch was probably constantly searching for a wifi connection?

In reply to Alan Cole.

mine is much worse than 12%… I go from 100% to the low battery warning in about 16 hours. I’ll have to try this as this has happened twice in the last week…

I have the same problem. firmware 8.20 and the battery is discharging daily. went to Garmin support and since it is out of warranty Garmin wants $170 to fix it. My battery drainage problem happened once before but mysteriously fixed itself. this is the second time and repeated “shutoff and restart” attempts have failed. I have been testing gear for an attempt at the PCT. needless to say I am disheartened by the lack of reliability of the Fenix 3. when it works I love it but I can’t rely on it to work consistently. Garmin Hellllllppppp!!!!!!!!!!

In reply to ROBERT. I just updated my fenix 3 to 8.20 and battery drain is crazy - empty in 2 days. Factory reset didn`t help. Any proposals what to do? Contact service?
