@isazi how impactful is this calibration thing I keep hearing about? When I got my S7 I left it connected for the entire duration of all system updates and app updates. When everything I could update was updated, I took the watch off the charger and wore it for 2 days before it needed charging again. I get the impression that really it’s just a matter of making sure everything is done updating before using it.

@aleksander-h not sure if the wearos app can predict battery life during the first charge cycle that well.

1. have you ensured that there is no app optimization on the wear os app?
   Android actively manages what apps are kept in memory, and unfortunately they haven’t marked wear os as one to always keep in memory, so some phones will automatically kill the app if it has been static for a while. By setting the wear os app on your phone to be unrestricted it will always keep it in memory and thus your bluetooth connection will not drop. (Suunto and other manufacturers really need to add this to their setup documentation: On phone - settings - apps & notifications - find the wear os app, click on it. Look for a battery optimization option, if none, check in battery and or memory sections - one of them will have an option to not restrict the app. For OnePlus in the app info there is a battery optimization section, clicking on it provides 3 options - Intelligent control (android decides) Optimise (restricts background activity - means when not using it is closed), Don’t optimise - means even when not using it, it will stay active in background and not be closed by android ram/battery management.)

2. this is probably a combination of new watch (takes a couple of days to settle in) and the issue from point 1. When your watch disconnects from bluetooth - it will search for connection again, and then search and connect to wifi if available. leaving watch on wifi consumes a lot more battery, and those searches take up battery too.
   Would also suggest setting watch’s play store to manual update (helps those occasional battery drains, when it updates a load of apps at inconvient times) - you will get a notification when an update is available.
   Also make sure you update all play store apps on watch, and the watches firmware (settings - system - about - sytem updates). Keep doing this until you are on latest update (see forum for latest version).

@isazi - any chance we can sticky the set up of wear os on phone to not be optimized, battery life first couple of days and play store on manual update, and to update all play store and firmware before using watch.

Gives new people a quick help and suggestion of first couple of things they should do on their watch.

[isazi]

@jamie-bg could be an idea, a sticky topic on the first steps with the S7.

[Jamie BG]

@isazi I think that would be a good idea.
Like the items I suggested.

Hi Jamie - the optimization is ’ not optimized’ .
i havent had the problem for 1 day now keeping both the phone and watch charged and close to each other. im just trying to understand what causes the disconnect as it quite painfull trying to connect them togther again. i have recieved a couple of time in the last 48hrs a notification on the watch to pair with a passcode to phone which when i click the tick mark it pairs ok. not sure if it should be asking me this or not really.

[Jamie BG]

@woolz - Never had to provide a pass code when it misses connection and reconnection - tends to be automatic and within a couple of minutes. Once paired it should remember the pass code.
Have you gone into phones bluetooth settings and checked them.

Does it also request pair code when you put phone in plane mode. then switch off plane mode and let it reconnect automatically?

Would also suggest a restart of watch and phone - can often help fix glitches.

@jamie-bg
hi jamie - just tried various different manual disconnection methods including - restarting watch/ turning watch off/ areophane mode on watch/ turning Bluetooth off on phone.
actually none of the above caused any issues when the devices were trying to reconnect.

the only time it did fail is when either i put the phone into airplane mode OR turning phone off.
when the phone tries to establish connection after either of these methods it prompts my watch and phone to confirm a passcode.

[Jamie BG]

@woolz - I suspect this is something on the samsung (phone) side of things, and would look at your bluetooth connection settings on the phone in regards to the watch connection.

[isazi]

Hello people, as suggested here we are going to have a pinned post in the S7 category with some first day information readily available.

[Jamie BG]

@isazi Thank you - I am sure new users would appreciate that.
I know I will - avoid having to repeat this due to people refusing/forgetting to use search.

@jamie-bg
ill keep looking into the phone settings and see how i get on.
ive tried it multiple times today and i can only get the watch and phone to disconnect if the phone switches off.
the watch and phone then prompt for a passcode acceptance once turned back on.

also battery life has been much better last few days.
example: yesterday i had 40% left after a full day wearing + 1 hour exercise. today i have 70% left at 5pm.
