My battery life has been hit and miss as well, but I think it has a LOT of do with usage. I am getting BETTER life, overall, on the GW4C (Non-LTE) than my Gear Watch 3 (LTE).
Busy day typically has me doing a fair bit of walking, but I also try and get out to cycle as well. I track my cycling via the watch as well as my other activities.
Non-Busy day is everything above minus the cycling.
I only have a few notifications sent to my watch as well as using AOD.
Busy Day, start at 100% (I charge in the morning while I am showering and go from this point).
By the next morning when I am ready to put it on the charger, I have more than 50% battery left.
Non-Busy day, I have between 60% to 65% when I put it on the charger.
Let's see if I can get all my settings listed:
- AoD: On
- Notifications: 3 Email Apps, Text, Calls, Voicemail
- Brightness: Auto
- HR/O2 level checking: Every 10 mins
- At night: Bedtime Mode is ON
- Watch Face: AR Emoji
- Weather every 3 hours
- Volumes: Ring: 8 / Media: 5 / Notifications: 8 / System 6
I have found that since I have Google Messages now as default, I am responding to texts more from my watch than I used too, so this is a factor too.
It's impossible to list everything that can impact the battery life, but overall, I am happy with the Watch 4 Classic (Non-LTE)
