Looking to bring my series 3 watch on a 3 day trip. I'm looking to see what people think my battery life will be like with the following factors:

  1. I wont have cell phone service because my phone will be in airplane mode.
  2. I will not be tracking my workout, just wearing it normally.
  3. Watch will not have "raise to wake" turned on
With that being said, would you expect the battery to easily last those 3 days? I AM bringing a battery bank but wanted to use that more for charging my phone if need be.

Also, what would battery life be like IF I wanted to track the hike?

Definitely. Also don’t wear it when you’re sleeping.

To properly track Hiking you’ll need watchOS 5 though.

I am excited that OS 5 does have a proper Hiking profile. If I were to track the hike, I already have all the maps downloaded on WorkOutDoors.

Might be a stupid question, but can you turn off bluetooth on the phone and wear the watch for a day, and then at the end of the day, turn bluetooth back on and have the watch sync up your activity for the day to the phone?

Interesting question. Should actually be working that way. But can't you just try beforehand? Like today?

Yeah definitely. I can go for a walk at lunch and see

EDIT: Just went on a very fast paced walk. Before the walk, my phone said 4 minutes of exercise. Turned off bluetooth on the phone. After the walk, Watch said 11 minutes of exercise. Turned bluetooth back on and the watch and synced synced up just fine. Phone now says 11 minutes. Appears to work fine.

Are you gonna being using cellular on the watch? If youre saying you wont have any connectivity to the watch it'll prob last longer than those 3 days haha. My S3 will last 2-2.5 days no issues.

I’d turn on theater mode as well. That should help with battery life if you aren’t waking he screen every time you lift your hand.

Yes, you can.. absolutely.

It’s just like you’re going out for a walk but forget your iPhone. When you come back the watch will sync with the phone automatically.

I pack a portable charger with me similar to this. It can charge my watch and phone in case of an emergency.

I'm only 155-160 lbs so I'm not a fan of carrying anything that isn't crucial but I can justify a charger. I bought these which are virtually weightless and ditched a tent light so in the end I reduced weight and added functionality. Those things are so cheap they are practically disposable. They also work as a good emergency light in a power outage at home.

I have this "Amber" charging case for my watch. I use it whenever I go away for a trip. It can easily charge my watch over the course of a week. I simply put the watch in the case when I sleep and when I wake up it's fully charged ready for another day. The case let you charge your phone, but the case battery is very small for phone usage, so I avoid that.

There are cheaper ones on Amazon than the one I have, same idea though. The only drawback is you need to get another watch charging cord.

Should be no problem, until you begin tracking the hike. Then you *may* eak out 3 days.

Better to put the watch in Airplane mode, otherwise it will spend the entire time searching for WiFi/cell networks.

So for the 3 days, I kept the watch in airplane mode all day and all night. I did not track the hiking, just wore my watch normally. At the beginning of the third day, I had about 35-40% battery left. Each night, I turned on blue tooth on the watch and phone just to sync activity info the watch had stored throughout the day to the phone and then put it back into airplane mode.

The last day I charged my watch and tracked the hike with Gaia. A 4.5 hour made my phone battery go from 90% to 35%..sucks but that's why I don't track my hikes.

Side note, HR readings were sometimes spotty. Sometimes an hour would go by without recording my HR when looking back at the weekend in HeartWatch app. Not sure whats up with that..
