Battery LIfe

@Brad_Olwin I disagree with you on the battery. I feel wear os is a bit like Android and it does take a couple of days to a week or two for it to bed down.
It also doesn’t tend to help that or usage in this period often isn’t normal usage as we test, check and try out features. I.e. use isn’t normal.
-
Honestly I am very supprosed how good battery is with S7. I had 2x 30m runs since taking watch from the charger. Suunto indeed did a great work with WearOS optimization.
-
This night, I switched off WiFi, BT, NFC, Location manually instead of going in airplane mode. As well switched off gestures instead of going in theater mode (I’m unable to switch alarm off in Th.mode) and my battery went from 81% to 77%
Anyway Location (from phone and watch) is necessary for everyday use ? I mean, activity itself is using GPS even if it is switched off, so during the day, it might help battery last longer when I switch it off whilst sitting indoor ? -

Can find out which of these settings makes the difference? -
@Egika - will to bet it is wifi/bluetooth
-
I’ll try to figure it out what exactly is draining the battery most. The night before I used only theater mode and airplane mode, Location on and it was around 8-9% , it might be gestures as well if I was moving my arm during the night
But I’m wondering if that setting for Location makes difference too. I let it off for today, it seems like the battery holds better. It would be good if somebody who was testing it will give us an opinion too. -
@Zab_55 -
This is how I set up my watch - AOD on, Minimal ambient mode (depends on watch face), 24/7HR off, Tilt to wake off, Touch to wake on, bluetooth on, wifi on, nfc off, location on, Gestures off, screen timeout at 5s. With this set up I generally run between 2%-3% hour while watch is connected to phone. Any disconnects to phone can make battery usage ramp up as a) it tries to reconnect using bluetooth, b) as wiif is on it will switch to that and it has higher battery consumption [make sure that on your phone the wear os and suunto app are both set so that they aren’t optimized for battery - i.e. android will not close these apps automatically / Make sure that your google apps are up to date - if not it can create additional disconnects]Alternatively (keeping the same set up) but switching AOD to off I will get between 1% to 1.5% battery usage per hour.

@Jamie-BG can’t understand how you could have only 2-3% with those settings. Wifi and Location are IMO worst for battery, not speaking about AOD. That’s really great.
But my comment was positive, I was reacting to those comments when guys had truly bad battery loss during the night and maybe airplane mode vs switching off WiFi and BT manually makes some difference
I’m totally happy with 4% loss during the night.
My concern is if that Location is a must for daily use without activity. -
The perfect feature would be “sleep mode” set with hours when you sleep, when watch at least will disable wrist to wake to save battery life when accidentaly wake screen while sleeping
-
@masi0 - There are automation apps that will work on your watch. If you can get one to set the lock touch-screen and set watch to cinema mode, that might resolve your issue. It may even be able to change your wake settings.
-
I tried cinema mode before , but alarm in the morning did not switch the display on and I had to push the button and alarm automatically disappeared but kept vibrating lol
-
@Zab_55 there seems to be a bug with cinema mode and alarm. I need to unlock the watch twice before I can stop the alarm.

One more question related to the battery.
What type of charger do you guys use ? I mean if standard Phone charger with 5V= 1.0A output is fine or it should be lower output for this type of battery.
Thanks ! -
@Zab_55 honestly, I use the first phone charger I see at home.
Watch: Suunto Vertical Ti

this is a good question. i have 36w charger i use for my pixel phone and spare usb port i used to connect suunto. it is odd however that when i connected, however i saw some strange behaviour.
when i first check how many % is charged it showed 49% but 20-30 minut later 98% which i am not sure if is possible
i plan to use chromecast charger 5V 1A this time to see if anything will change
-
@masi0 The S7 charges very quickly, I think to nearly 100% in 1.5h
-
@isazi Me too!
-
@Zab_55 me too
-
Just asking because some cell phone batteries are not suitable for higher output chargers (1,5-2 A) , so I was curious if the 1A is just fine and I shouldn’t be worried about battery damage.
Thanks guys for reply ! -
@Zab_55 charging current is always controlled in the device. The charger rated current is just its max capacity.
And 1A is absolutely sufficient for the watch. These small batteries don’t charge at more.
Higher charger rating does no harm though - it’s just not used by the watch.
