Hi guys. Just got my S7 for Xmas. The watch is now set up and has done a software update from what I could tell yesterday on the charger.

I have just taken the watch off the charger and it says 7 hours until the battery runs out!!

It is on my wrist but it only says Android system has used 1% of the battery which would be right as it has only been off the charger for 5 mins.

Any idea what is causing this, is there a setting which is draining the battery?

@Scott-Gibson without knowing how you ve set up the watch its difficult to know.

If the watch is new the discharge rate is an estimate based on usage so far. Its likely not right.

But for me I turn off the WiFi when I wake up.
The display being set to always on uses more battery rather than tilt to wake.

Any additional apps, notifications from the phone having NFC on.
It all takes up battery life

Just remember the suunto 7 is a smart watch with some sport watch functionality. The battery life is at best two or three days with the smart functions on

@Scott-Gibson if you are on Android turn the wear os app battery optimization to off.

Scott Gibson

@Dimitrios-Kanellopoulos thanks for the info, where abouts is this in the app? I have tried looking In the battery section on wear os but couldn’t see anything.

Positive news though. I have ran two 5.6km runs and a 3k walk on high accuracy and always on heart rate and the battery still has 25% left and has been off the charge for over 24 hours. Even made a couple of Google pay transaction.

If it continues like this there will be no complaints from me regarding battery life.

Loving it so far.

@meyton89 thanks for your quick response. You were right once things settled down the battery life has been great and you can see my previous reply above for more detail.

Thanks again.

I just picked one of these up yesterday. I got less then 12 hours on the first charge, with Bluetooth at the top of the battery use list. So I wiped it and set it up again. 13 hours with 8% left. Did I just end up with a bad one? Both times I specifically didn’t customize anything or install any apps to get an out of box battery impression, and I did no activities. I am very familiar with android wear and how just about anything 3rd party can destroy battery life, so I leave all my wearOS watches as close to out of box as I can. By comparison I also have a ticwatch 3 pro that now gets 4-5 days out of one charge.

Should I return mine or give it a couple days to learn battery optimizations?

@james-wylie in my experience the first day battery life is pretty bad, but after that you should get more or less 2 days.

@james-wylie take it off bluetooth, set it to wifi, put it on the charger, and check your firmware updates. Keep checking and updating until on the latest version i.e. build num ber PXDZ etc.
Do the same with the play store until your wear os is 2.23 and home app is 2.43.
Check checking and updating the play store until no more updates. Also set play store to manual update (you will get a notification when there is an update available).
Let watch fully charge.
Reboot watch and connect back up to wear os app on phone.
Make sure that wear os app is unrestricted, so you don’t lose bluetooth connection.

Ignore any battery history/projections for first couple of days. But from here on in your should get +1.5 days.

Two of the major battery drain issues are:

Auto updates - huge battery drain whether on wifi or via bluetooth.
Disconnects mean that watch will switch over to wifi, which can tend to draw more battery than bluetooth.

James Wylie

@jamie-bg Yeah that’s my usual procedure. Seem battery life has settled down today, about 2% an hour.

If anyone is new to wearOS… always just go through the tutorial and let it sit for a bit to get a benchmark battery life on it. I cant even count how many times I have had to reset various other watches because I downloaded a watch face or app that destroyed the battery.

Jamie BG

@james-wylie 2%/hr is about what I get with 3rd party watch face, AOD on, touch to wake on, tilt to wake off, and normal usage.

James Wylie

@jamie-bg I seem to be falling into some kind of bug trap with both my wearos watches. It seems like if I play any music on my samsung galaxy fold 2, the watch gets stuck in some mode where it thinks I am playing music and the bluetooth battery drain goes through the roof. I don’t know why it does, but my guess is its polling for the current song for music controls. The only fix seems to be to reboot the phone and the watch, but it comes back as soon as I start playing music again. Not sure if this is a samsung/wearos bug or what, but its getting really old.

Jamie BG

@james-wylie seen a similar comment on Reddit. Haven’t experienced it myself.

Jamie BG

Anybody noticed an improvement to battery life. Used to get between 2 - 2.5% with AOD on & touch to wake (non suunto face / using marine commander).

Noticed that this week I am pretty much always much closer to the 2% mark if not slightly better, where previously was often closer to 2.5% mark. Seems that since the last wear os update might be getting a 0.5% /hr improvement on battery life. And while I know that isn’t massive (about 0.5 day extension); if I am correct, its interesting to see that H MR2 and wear os updates are finally starting to show the anticipated improvements.

Yup! I charged to 100% as of 19:00pm yesterday, 19hrs later I’m on 75% (drain of less than 1.5%/hr - I feel I was closer to 2.5 to 3% per hour prior to this last couple of weeks)

WearOS app suggesting I could get another 3 days (although I’ll charge to full before and then after a run tomorrow evening).

@jamie-bg I get 2 days per charge with mine. Can’t say I noticed much difference.

@meyton89 battery Life best Two days??? No no no , only 19 hours maybe!!!

isazi

@andrea-antonio-guadalupi still two days for me.

olymay

@andrea-antonio-guadalupi if I don’t use the GPS then I am getting over 70 hours of battery life from mine.

If you are only getting 19 hours then either you are tracking lots of activities (bravo if so!) or you need to look into what apps are draining your battery.

Do you have any third party apps installed? If so, which ones?

Jamie BG

@olymay also check gesture settings. Tilt to wake doesn’t with for me (wakes up watch too much), touch to wake works better.

olymay

@jamie-bg I use tilt to wake (with power saver tilt) as I may be a tech geek, but I’m still a traditionalist and want to be able to look at my watch using just one hand
