Question

[Jamie BG]

@andreas7 - I am linked to an Android phone and I tend to find that it runs at about 2% per hour battery usage with always on screen using an ambient watch face, with screen off this can drop to around 1% to 2%.I would think that is what you should find, but then I am linked to Android, so it may be different for you as iPhone may cause it to work differently.

To troubleshoot:

1. Find the biggest battery drain can be due to connectivity issues: When it drains like that check what symbols are in the settings pull down bar (top of watch screen) - does it have the wifi indicator, bluetooth indicator or a cloud. If wifi or cloud it means you are disconnected or using wifi and it will drain battery significantly quicker. Reconnect via bluetooth. (Note that if phone and watch are sleeping both with screen off - you may get a cloud for a short period while it checks connectivity - reason why reduces battery use below 2% per hour.
2. Have you checked to make sure you are on the latest software version for watch (do a system update check - when I got mine I had to perform three updates until I got the June 30th update).
3. What watchface are you using? Are you using ambient mode? Are you using always on screen?

@andreas7 it’s on the high side…
I have started the day with 100% this morning and in 5h my battery went down to 87%

Have you tried re-booting the watch and check again?
What can also help is to let it decharge once until it switches off to make sure the lower charge level is accurately calibrated.

@Jamie-BG Thank you for your reply.

1. It’s only bluetooth connectivity active. I have deactivate the wi-fi.
2. I get the message that system is updated
3. Marine. Ambient mode? (can you make it clear?). No

@Egika Thank you also for you help.

1. Yes, I tried.
2. Ok, I will do it.

Do you think that the problem maybe that I have the background heart rate on???

I’m on iOs (11 pro) and have no problems with battery life.
Here are 2 examples of my usage :

My screen brightness is on automatic
wrist motion enabled (energy mode)

@Tom-Broekaert I don’t know what is going on with my watch m8.

Background heart rate is on via “heart trace app”
Standard “marine” watch face.

Have a few days patience. It will get better

Heart Trace 2? This can be part of the issue. Depending on how you configured it. By default, the watch will sample your heart rate every 15mins and push this information into Google Fit.
If you set the app to sample at a higher rate (and even at the same rate just in parallel to the system measurement) it will definitely eat more battery.

I’m on default settings in heart trace. I don’t see a big impact on battery life

@Tom-Broekaert sorry, mistook you with the OP

@andreas7
Ambient mode is the power saving mode for watch faces. Depending on the watch face maker/and watch face this can mean a couple of different things. Some watch faces will come with this as standard, some will give you an option in the watch face settings to choose how much power saving is acheived by what and how the watch face is shown on the screen and some don’t give you an option so it may or may not be included.

Marine does have an ambient mode, an no option to change or set it, it is automatic. When your watch face is activey it will be brighter and have all the hour numbers displayed. In ambient mode (sleeping), these numbers and some of the detail disappears. I would suspect that this isn’t a particularly good battery saving ambient mode as there is still a lot of movement and detail on the screen.

Compare this to Heat Map watch face where the background map completely disappears.

One of my favourite watch faces marine commander is very customizable and andthe colourful watch face completely disappears in ambient mode and becomes simple white dots indicating the hours with two white hands for minutes and hours. This will draw far less power than Marine watch face as simple colours, mainly black oled screen.

@Jamie-BG Thank you very much for your reply. I’m using now the heat map watch face. Also one more question, when my watch disconnected from phone because you are away for example, is there an option shows up the little cloud in sleeping mode in the top of the screen???

[Brad_Olwin]

@andreas7 Swipe down and tap on the cloud with the line through it to reconnect or swipe up and open the reconnect message. On my iPhone, the watch will reconnect with these two options.

[Jamie BG]

@andreas7 if you are looking for an app that advises you that you are disconnected there is one in the play store (old and not recently update but I believe it still works)

If you are asking how to reconnect Brad provided some good suggestions, however have tended to find its my phone that is the issue. On phone long pressing Bluetooth icon in notification/settings bar (or go via settings) I find it shows my watch isn’t connected. I go into the paired but not connected section and click on my Suunto. This takes you into Bluetooth settings for the watch. Clicking on connect button works. If that fails open wear os app on phone, disconnect and then connect again, if necessary also switch watch Bluetooth on and off, if still struggling also try connecting suunto app on phone.
