Insane Battery drain since 15.10

Hi,

Since updating my Fenix5 to 15.10 the Battery drains about 1% per hour.
Whats wrong?
With Firmware 12.40 it needed about 6% per DAY.
With newer updates since 12.40 it gets worse and worse, but now with 1% per hour …. thats insane.

What can I do?
Is there any possibilty to Downgrade?

With best Regards,
Patrick

I am still convinced, that foreign APPs, foreign Widgets or high rate data transfer (BT or WiFi) are the reason for high battery consum.
Please write always if you complain, what kind of APPS or Widget…

I just made a full factory reset and unfortunately the battery is draining a lot! With everything off and with garmin watch face it is doing 0.3% used to be 0.1% /h. With heart sensor on, activity tracker…

You try a soft reset after the update - I do it after every update, every charge, helps with clearing stuck processes that suck up battery.

Test with default watch face - might be an issue with a custom…

I already did that. My Garmin Express is not showing 15.40 yet, it's not available to my region. But for the Garmin Connect there is an update, I am not sure what kind of update is that...

Fenix 5x - Large battery drain when bluetooth sensor scanning left on:
If you use a sensor eg HRM chest strap or footpod make sure to disconnect it and turn of scanning after an activity otherwise your battery will be shot very quickly >2% per hour vs (~0.3 with it off)

Hi guys I found an issue. My Garmin Connect under Garmin Devices shows a software update that never ends. The problem is I wait for hours untill it finishes but it restarts all over again. It is certainly a bug! Draining all my battery.... Mine is a f5X. And opening the watch with the express it shows me nothing ... I reinstalled everything and made a factory reset, still the same issue....

I’m having the same issue on my 5s - I charged to 100% at 10am, went for a 2.5 hour ski, and I’m now at 15% at 6pm. My software update seems to be hanging as well (no 3rd party watch faces or apps, and all my pairable devices - HRM, Vector pedals, etc. - are turned off). I’ve got 15.10 loaded on right now, but I’ll try plugging into GE to see if that pushes the update...

I had exactly the same problem with 15.10

Now 15.40 i think is normal for my f5.

Hello! I had a Garmin Instinct watch, a very good and reliable watch, but with some minuses compared to Fenix 5. I changed that watch, hoping that Fenix 5 was a top of the range. But ... Battery consumption is a big disappointment. Garmin, please, on behalf of all the owners of Fenix 5, solve this situation! In the two weeks since I got the clock, I'm already sorry about the choice / change I made.

Same here, very sad and disappointment...

Garmin, CRYING OUT LOUD, on behalf of all the owners of Fenix 5, solve this situation!

THIS IS RIDICULOUS!

the battery life on the 5s is ridiculous. I am on my 3rd watch, ran a half marathon on Sunday, battery life 100% at 6am. Was already down to 88% by 9am, with notifications off & standard watch face. race started 09:40 (my zone), I had pace alerts on but by 10 miles the watch was at 10%!!! Its meant to be getting me round a marathon next month, no chance of that happening. have put in a complaint with garmin and they are offering yet another replacement. I dont want watch number 4, I want one that does what it says is will especially for the money that it has cost. Ive now asked for a refund & will likely go over to suunto as Ive lost all faith in garmin now.

I can confirm that. I've been using my Fenix 5 since it's launched, I'm kind of Garmin purist, so I only use stock watch faces, apps, etc. My display brightness is set to 10% (8 sec), BT is turned during the day (turned off at night). With around 7 hours a week of GPS use (every sec./gps only) I charge my watch after 7-8 days. Firmware always up to date.
