Disappointing battery life

This is frustrating. I'm happy with my unit. But it annoys me that if I were to have problems in the future Garmin UK would be difficult to deal with.

I also wish I held out and bought from Amazon or perhaps John Lewis (they don't yet have stock), their aftercare would be far better than Cotswold Outdoors which I imagine will be horrendous if I need them.

Still fingers crossed I have no probs.

Get a refund ASAP and buy again from Amazon. Whilst I dislike their monopoly..they put all other businesses to shame and they deserve to collapse in my opinion.

this forum is pretty much terrible too. Not authrozied... They should be embarrassed.

Yes, they seem to be struggling to sort the problems out with posting. It's been going on a wee bit long. Have you posted in the thread for the vBulletin?

My Fenix 5+ appears to have quite an erratic battery. I had planned to let the watch run dry, but needed to use it this morning for a client workout. So charged it for 20 mins which took the % to 18. That was at 9pm last night. After working out for an hour with the watch measuring strength, this morning, there has been no % drop in the last 10 hours. Where as I had been seeing % drops almost hourly. What I have noticed is there appears to be a quick battery drain after using GPS on runs. Almost as if GPS is not turning off.

No drop in battery % for 10 hours then within two hours a 2% battery drop, this happens after an activity. As long as no activity is recorded the battery drain is the same as my Fenix 5, but once an activity is recorded there is a shape increase in battery drain, which then does not appear to stabilise.

And how it is compared GPS only vs GPS+galileo in battery drain?

New Fenix 5+ here..

A quick update on fw6.00 with F5S+. I have the following setup:

- BT ON - connected to my S8 getting Smart Notifications 24/7
- Wifi OFF (just a test)
- OHR 24/7
- Ran 17k this week. I find that running (GPS only, with Stryd, with Datarun Premiun 5 field) takes up a slightly more than 1% per km.

Started fully charged Tuesday 2100. Now Sunday 11:35 I have 13% left. I'm sure battery wil last until 2100 tonight. That's 5 days + 17k's of running...

I think that's absolutely fine. Without running, I take I'd get 7d of battery time...

Just my 2 cent ;-)

I also believe there's an issue with post GPS battery drainage. So I've managed to hit just over 8 days with 75% BT on, 1h40m of running (GPS and Galileo - 40m of it with music), 1hr 40 outdoor cycling GPS only / ant+, 55m indoor cycling ant+ and 40m swimming. Got down to 2% before recharging. Wouldn't normally drain battery too low but wanted to test. I think this is pretty good and could imagine an easy 12 days as a smartwatch only.

Will see how it goes over next few weeks although I will try and keep the battery above 40% from now on. As for charging - the gauge is still all over the place. 1 hr charge from 2% showed 25. Rebooted and it was 40. And when it shows 100, it's usually around 91/92 and needs an extra hour to hit a real 100%.

I am beginning to think whether the battery issues are to do with the algorithm used to calculate the remaining battery, rather than the battery itself.

For the charging issue - I would agree and hopefully an easy fix for Garmin. If the post GPS battery drain is a confirmed bug then, again, hopefully something that can be fixed by the gods above :-)

Don’t want to speak too soon but I think I may be seeing an improvement on 6.0. For the first time ever I charged my watch to 91% restarted it and it still showed 91%. This was Sunday 1p.m. I think did one hour twenty five minute run with GPS. 10pm Monday night and I’m at 77%. That’s s
