FR945 - Battery life (FW 5.00)

Dear all,

I‘ve checking the forum but unfortunately I couldn‘t find any answer to my problem/ question:

Since I‘ve upgraded to FW 5.00 my battery drain is according to the Battery widget 1,17% per hour, so my watch needs to be recharged every 3,5 days (which doesn‘t comply with the battery life claimed from Garmin)!

My „watch mode“ settings are:

- BT on

- OHR on

- PO off

- Wifi off

- Music off

Right now I‘m using Infocal as watch face

https://apps.garmin.com/de-AT/apps/c97c4e34-55e4-4601-b5c2-45763bc481a2

I wear my FR945 every day 24/7 and I‘m training 1-2 hours per day (running, tennis or cycling) with GPS + GLONASS & HRM-Tri chest strap.

Could you please let me know which settings I should make in order to achieve a battery usage of 0.3-0.5%/ hour as most of you seem to have?

Please don‘t get me wrong I could basically live with recharging my FR945 every 3,5 days but I was wondering how all others seem to have a way better battery lifetime than I have!?

My watch is two weeks old so age shouldn’t be an issue...

Looking forward to your feedback, thanks in advance

My watch is 2 months old.

I can certainly tell you that battery life is way less than expected from the specs. But I am just enjoying the watch though.

I have to charge like every 3-4 days.

I wear it 24/7 and my PO is on during sleep only.

I run like 3-4 times a week. Each run is 1-2 hours.

I can agree that the battery life has been "less than advertised" for me as well. But I've had better success once I moved away from a non-Garmin watch face. That's one change you could make.

Otherwise, it's hard to really get a handle on battery usage as I do so many activities in a week (10-15 hours worth typically) and I receive a bunch of text messages which vibrate the watch regularly. All that said, i am usually charging every 3-4 days.

Thanks DPSK for your answer, it seems that my battery drain is the same as yours (3-4 days to recharge), so I‘m not the only one to miss the claimed battery life

Are you using Wifi & BT (always on)?

badbri

thanks as well for your feedback, may I ask you for your settings?

Are you using Wifi?

0 badbri over 4 years ago in reply to Manati 1079226

BT - On

PO - Off

Wifi - Enabled

Music - Occasionally, probably 20-25% of total run time is music

Watchface - Garmin's "Big Bang"

OHR - On (but I typically use external HRM when in activity)

Wifi doesn't use battery on standby. It's off. It's only used on syncs over it. Not like BT that is on, if you use it.

My BT and Wifi are always on.

But after reading your post, I decided to switch it off and monitor.

I don't think the Wifi is necessary.

I know that turning BT off will decrease battery drain, but how much I'm not sure. I have turned it on/off on some long runs with/without my phone with me (the only device connected via BT) and it made a difference.

Yes BT definitely consumes more.

I need to switch it ON because I have a tendency to open GC throughout the day.

Maybe I should change the habit.

Since I wear my 945 throughout the day (I got spoiled with the notifications way back with my original Fenix), BT being on is a use-case for me that I don't see changing.
