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!

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 !

Egika

@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.

@Egika cool, thank you for your reply !

Hey guys, me again.
I was wondering what battery consumption are you getting in forest areas during mountaineering ? Let’s say in GPS - Good setting and BT on/ off , WiFi off.

@Jamie-BG this is not a nice solution, new smart watches can even get you when you fall asleep. your automatic question can understand … it should have been so much easier for suunto

Jamie BG

@fatih-varol really don’t understand your comment, especially in relation to my comment.

Suunto 7 doesn’t have native sleep tracking yet, but would assume that hopefully when/if it does get it, it would be automated as yes there are a lot that does this. But again that may come down to battery consumption, but we should at least get that choice.

While yes it would be nice if suunto included routines/profiles within its firmware (like fossil has done - which by the way are extremely buggy and cause major issues), there are 3rd party apps which can already do a lot of this. Personally as there is availability for this (and or it really should be included with wear os - but then this functionality was dropped from Android a couple of years ago - though some bits do live on, but not as a full profile switcher); I personally would rather suunto focus on more important stuff, like getting native sleep tracking, like improving the bugs they do have, like improving route navigation, battery life etc - stuff we don’t really have/and or where suunto can do so much better than the options we do have.

I am getting 14h to 20h battery life. Airplane mode, good GPS

Jamie BG

@Brad_Olwin is that with our without routes/maps?

When putting the heart rate monitoring, google fit, in 2 plane in the battery stattus appears “overcalculated” with a very high% of expenditure. Any solution?
Sorry for my bad english.

Jamie BG

Assume you are referring to using google fit to track activities - if so then yes it does use a lot more battery than the suunto app (or it used to - not sure if the new update does or doesn’t) as it didn’t use the co-processor like the suunto app does, so it keeps the watch in high processor/power mode.

If you are referring to the 24/7 HR monitoring - it didn’t used to take that much additional power. Normally run at around 2% per hour (battery usage) with AOD on; with 24/7HR it used to add less than 0.5% per hour to that consumption.Note that google fit only takes a reading every 15/25 mins (so it is only waking up watch occasionally out of low power - probably as often as you get a notification).

Ander Lehena

@Jamie-BG I usually use it to sleep track on IOS.

Jamie BG

@Ander-Lehena assume you are using Sleep as Android as no native sleep tracking yet? Note this 3rd party app doesn’t use the co-processor, so its battery consumption will be high. Most people seem to say its takes an extra 1-1.5% of battery per hour - and switching off flight mode isn’t going to save battery due to this. Any battery save due to bluetooth will be reasonably minimal.
Hope you are switching AOD off and locking touch screen (I know people who have had major battery issues their actions while sleeping were keeping the screen alive.

Brad_Olwin

@Jamie-BG With maps no routes. Not much time spent on maps page.

Jamie BG

@Brad_Olwin That makes sense based on what I am getting which is around 13-16 hours but connected to phone (btw 6-8% battery use per hour)

I’ve just had an interesting and frustrating battery experience with my Suunto 7.

I went for a lunchtime run which lasted 1hr17min. I had GPS set to max accuracy, map screen always on, following a route, and streaming music from the S7 to Bluetooth headphones.

When I set off, the battery % was somewhere in the mid 70’s, more than enough for a run such as this.
As I crossed the finish line and stopped the run, it alerted me that the battery was down to 5%.

I have never seen battery consumption like this before! I have minimal apps installed on the watch with nothing running in the background. I used the same settings, apps, and headphones as I always use, nothing has changed as far as I can tell.

I have added a screenshot of the watch battery (from WearOS app on the phone) to show the steep drop in battery. (the gap in the graph is overnight where I take the watch off and put it into battery saver mode).

Battery life on the S7 is typically stellar, so I am a little confused as to why it wa so poor during this activity.

@olymay well, check if it happens again. I can expect one-off strange behavior from something like WearOS, but if it becomes common there must be something wrong.
