    Do you allow app refresh in background on your AW? what will i be missin if i’ll disable it?

    Heart monitoring will be interrupted, for instance?

    Does app refresh in background have a huge impact on battery life?

    Thank you

    I leave them all on and I don’t have battery issues. Wake up at 5:45 AM go to the gym for an hour go to work and by bedtime I’m at 40-50% depending on usage. It’s great. That’s on my 44MM series 4. On the 42MM series 3 was about the same.

    Depending on the app it will just not load new data in the background, you will have to open the app to load new data. Heart monitoring will not he affected if you turn it off.

    i don't get what the setting is about sometimes...

    for examples, you can turn it off/on for timer... if i turn it off and use timer, the timer will work although i close the app. so, what's the difference?

    would the AW continue to register heart rate (i understood yes) and activities with refresh off? will i continue to receive notifications?
    reminders will be syncronized with phone any more?

    i'm trying to improve battery life as it drops approx 3% any hour, also during sleep 10-12% in 8 hours (i wear the watch with airplane mode), but infortunately AW does not give you any information about single apps battery usage, so i'm thinking of turning refresh off for all.

    Leave them on. You might as well be using a casio if you turn everything off.

    It means apps load data instantly when you open them so you are not left staring at your watch waiting.

    It's also smart and only updates when conditions are right and for the apps you use.

    So while you may have it on for your news app if you dont use it it will learn this and stop updating in the background.

    One of the very first things I do with iOS is TURN OFF Background App Refresh.

    Quite simply - I have no good reason why my apps should update when I'm not tending to them, or why they should be sucking up all my cell phone plan data when not using them.

    Didn't Google News app suck out 12Gb of data overnight, for someone recently?
