My vivoactive 4 is about 2 months old and I had the original vivoactive previously.
I've noticed that after I do a gps activity (run or walk), the battery keeps draining faster until I power cycle the watch.
After a reboot and full charge it uses about .5% per hour, but after an activity it will use 2-5% per hour.
Today a few hours after a walk I was fiddling with it to try find out why and went into a GPS walk activity and it instantly had a GPS lock. It got me thinking that perhaps the GPS has stayed on all this time after my activity. Then I didn't start the activity, but went out and back into the activity and it then made me wait for a GPS lock.
Perhaps I'm not operating the watch correctly and closing out of the activity after my walks and runs that cause the GPS to remain on.
After finishing and accepting the prompt to save the activity, I'm presented with a summary of the activity. What is the appropriate action to return to the watch function and stop the GPS properly? I've just been hitting B until it gets back to the watch, but tomorrow I'll try leaving it until it closes on it's own.
Thanks
