Disappointing battery life

I have F5+ since 4th-Jul. I'm not heavy user, but I was charging it only 3 times since purchase. normally it is every 7 days.
I have auto backlight enabled, HR 24/7 monitor my activity & sleep and have 3-4 45 minutes GPS training in a week. Connecting with smartphone via BT only for data synch 3-5 times per day.
Well I'm pretty satisfied with this, because I had only Android Wear watches so far, which was max only 3 days battery life without any sport functions used.
Charging from 8% takes around 3 hours via USB in laptop. SW 3.10.

I know I'm repeating myself but I'm getting bored of coming on here looking for any type of acknowledgement from Garmin (and yes, I have contacted them directly).

Charged to 100% yesterday, left charging for another 2 hours, went on a 1 hour bike ride which used a reported 6-7% (I'm good with that). Now 24 hours since taking it off charge I'm down to 51%. And I know from earlier trial and error that the watch will shut down when it hits zero. No fancy faces, apps or anything, just the same setup I used to get 10-14 days on out of my Fenix 5 between charges.

I know not everyone seems to be affected by this, but looking at the numbers who are there's clearly some sort of issue here beyond just a hardware defect affecting one or two devices. Until someone having these problems exchanges their f5+ and finds no issue with their replacement then I'll remain convinced it's a firmware issue and will wait (impatiently) for Garmin to sort it.

Yes, this would be also issue for me as something causes this battery drain in your watch, which is not affecting other users.

I've just upgraded to the Fenix 5 Plus after tow failed Fenix 5 Units (various issues). I was assured that the Plus version was a massive improvement and I'd have no issues at all.
Full charge from new on Sunday evening, and just daily wear has gotten me down to 46% as i sit here typing.
Not impressed.
I also have other issues with it which I won't fill the the thread with, but to say its a massive improvement is an overstatement in my opinion from what I have experienced in 3 days!
I will be persevering for a few months before I make any decisions - but the store have said if I'm not happy within 3 months then to return for a full refund!!
Hopefully it won't come to that, but it is what it is.
Come on Garmin, lets see some input please.

Been feeling under the weather lately so I was only using my watch as a smartwatch since charging it 2 days ago and during that time I only saw a 12% battery drain. This morning I went for a 45 minute run that drained a little over 4% of the battery, bringing it down to 82%. Since the run, about 5 hours ago, I have lost an additional 4% of the charge. I wonder what it is about doing a GPS activity that increased my battery drain even after the activity was done.

I'm having Wi-Fi syncing issues with my f5+ which I've posted about in another thread, but as Wi-Fi only activates immediately post-activity to upload, I was wondering whether extended Wi-Fi activity if it fails to connect or sync might account for the post-activity battery drain.

I'm going to disable Wi-Fi Auto-Upload (I think that's the only time Wi-Fi is ever activated) and see what difference that makes, but has anyone else already tried that?

I have still the same issue like you - however I realized now that if I turn off the Bluetooth sync on the Fenix 5+ and just activate it once per day I have a much better battery life than before.

I can now get around 6% battery drain per day for smartwatch usage. Also after GPS activity no big drain anymore. However this was not present on Fenix5 - there I kept Bluetooth sync always on (what I also prefer and would like to do with Fenix 5+)

I have still 83% battery left after 2 days (including 30 Minutes run with GPS + MUSIC) ... much better than before

I'm trying to run my watch down to 0% so I can give it a full charge cycle.
Just had a 15 minute tea break outside - turned on Maps to get a GPS Fix..... I went from 10% to 2% in 20 minutes!!! OUCH
And yes, forgive me for for sneaking an extra 5 minutes on my tea break - its so nice outside!

But seriously, 8% from standing around with just Maps activated is a joke!!!

Been following this thread and have the 010-01988-06 F5+ version. I received it last week, as it was on pre-order for quite a while and did not seem to release on time with the red marker version. Anyhow I have been tracking my battery this week and it seems to be somewhat normal to me. But wanted to share if anyone felt it should be performing better. I wear 24/7, have wrist HR on, WiFi turned off, BT to phone and all sensors disabled until they are needed. My activities are below and the sensors used.

Digging around in the menus on both the phone and the watch I have found two things turned on that I have now turned off to see if it makes a difference

On the watch I found Display Group Track on map turned on, I never use it on my watch so it is of no use to me. I do have the map as one of my screens on my GPS activities and rarely display it but I was wondering if maybe the watch uses this as a queue to communicate and update details during and maybe some time after an activity.

On the phone I had the option auto-update apps turned on, I don't actually think this works too well anyway as when I connect to Garmin Express it is still reporting that 4 apps are out of date and need updating. Again I wonder if the watch is trying to update after an activity (and perhaps failing) drinking more power.

I know I am digging in the dark but being a developer for over 30 years has taught me to never discount anything until you have tried it ;)
