Persistent Battery Issue with Garmin Forerunner 965 - Even after a new watch from the support

3209298 over 2 years ago

Hello everyone,

I want to share an ongoing issue with my Garmin Forerunner 965, despite a recent exchange with customer service. After experiencing rapid battery drain on the first model, I received a new watch, but the problem persists.

For instance, last night, the watch lost about 15% of its battery in airplane mode, with blood oxygen monitoring disabled. This is concerning, especially considering the cost of the watch. Before this, I used a previous Garmin Venu without such issues.

And of course, V16.17, features (AOD, blood oxygenation) have been disabled, and I even put airplane mode during the night…

I'm reaching out to the community for advice and suggestions. Have any of you encountered a similar situation? My dissatisfaction is growing, and I'm looking for practical solutions from Garmin support…

Thanks in advance for your feedback.

Are there any apps you have installed? Anything? Watch faces, you name it?

I have no issues whatsoever with FR965 battery life. I just spent a whole week in Belgium with daily route tracking, three runs (while listening to music), navigation and 24/7 on my wrist. I recharged once.

Not a all, no app and watch face without every second actualization.

I have the same issue. I'm was one 17.18 and it was justing on my desk. It was at 95%. After about 2 days, it was down to 5%. I've never seen it drop so fast before.

I had the same problem and I posted already about this issue. Garmin sent me a replacement but It seems good Sofar with the new unit.

Have you tried without airplane mode? I guess I read that on some devices/firmware it can be broken and use more battery

Have you tried without airplane mode? In the past I had issues with it.

The watch is constantly connected to my smartphone and the Garmin connect app 24/7, there is only a period of night with a "do not disturb" mode. No problems with watch battery consumption at the same time.

Blocking or restricting communication with your smartphone often results in more unfulfilled, scheduled synchronisations, which can have an impact on increased battery consumption.

Hypothesis, nothing more, from personal experience over the last 5 years with Garmin watches (945, 955, 965).
Also, be sure to put Garmin connect on the home screen of the Garmin mobile app after entering watch settings from the app.
Try reconsidering your "stealth" use of the watch and app connection.

I use airplane mode on while I sleep everytime.

Hey the replacement model still has the same problems....

The battery drops 10-15 percent at a random night.
