Battery draining quickly when updating firmware to ver 13.0 ?

On my 945 version 13 is the one that offers more autonomy

A mí, con la 13, o no llega a detectar gps o lo detecta al llevar bastante avanzada una actividad….. me gustaría volver a la versión anterior, es posible?

You're right, it happens to me often too

hola  tungvt me  pasado lo mismo con mi 945 tres meses de uso, desde que se instalo la versión 13.00 la bateria se agota en un día.

same here .. version 13 the battery is drenaid with all sensors off

I have the same issue now after the new update version 13.0

I got the update through Wi-Fi.

I've faced this since ver 12 and above.

and now it seems garmin has no plan for its users to come over this problem and this is why I don't recomment anyone else to buy or at least updating thier Garmin

Same problem after update to version 13 (

So about 2 weeks ago I sent my 945 back to Garmin because the watch was no longer connecting to Garmin Connect. Thanks to Garmin’s excellent customer service they sent me a new 945. However since the replacement watch would not load past the “converting GXP files” page, I had to send another one back. Once again Garmin demonstrated outstanding customer service by giving me free one day shipping and apologized for the inconvenience. However I received another replacement 945 and the battery drains like no other. The watch goes from %100 to %60 just overnight. Since I wasn’t using the first 945 that I sent back to Garmin I don’t remember this level of drainage being normal and I don’t know how the latest update has affected the watch. I also noticed that you have to keep turning on Pulse Ox because it keeps turning itself off. I have the Fenix 6x pro solar and I’ve never had either of these problems. It’s a shame because I intended to switch back to the 945 because I prefer its design and size over the Fenix. Hopefully these issues get sorted out.
