I just purchased my wi-fi frontier several days ago and immediately updated to 3.0. I was seeing about 5-6% battery usage per hour for the last two days with HR off, AOD off and NFC on. Today I decided to also turn off NFC and now see battery usage at about 1-1.5% per hour.
I turned NFC back on this morning and after 2.5 hours battery is at 99%. No other change to settings.
AOD - Off
HR - Off
Location - Off
WiFi - Off
I'm not exactly sure what this means, but much happier with battery consumption today.
Had the most recent update (battery improvement) installed 2 days ago. So far, I do not see any significant improvement. Did a reboot and shut down watch and a reboot phone but that did not change anything. Will continue to monitor the drain as it seems it did improve for a few users.
Should we consider what watchface we are using?
1: I hve not tested the original watchface, I have started using one that the developer of the watchface assure that will be 2 full days of normal usage. why? well I can see all the sensors active on my watchface.
2. Could be a good idea to compare the original watchface and not the ones that might use more battery?
just for reference I am using this watchface but yeah has more details and more actiity going on:
I have designed my own watch face which I have been using for about a year. Other that standard watch info it has battery level, steps and stairs because that info is useful to me. Under Tizen 184.108.40.206 normal battery drain was about 20-25% a day depending upon updates/messages/phone calls (just a few a day). Under Tizen 3.0 battry drain went to about 38-45% a day with everything staying just the same. Updated a couple of days ago with the "battery enhancement" software and really cannot tell that I fare much better. It looks like I am in the 35% battery drain a day. I will give it a few days to see if there is an improvement as reported by other users. Not sure if the battery is aging and not holding power as it used to or it is simply the new OS which does that. Again, for as much as I use the watch I should be in the 20-25% battery a day. And that does not even count that Tizen 3.0 is, allegedly, improving battery life by 30%. Yeah! and the tax reform is going to save me money!
Was so annoyed that I brought my Gear S3 Frontier back to Samsung for repair.. It was lasting 2 days before the update, 6 hours after the update.
Samsung replaced the battery and downgraded back to tizen2.
I'm back to 2 - 3 days usage. I also noticed that the Tizen3 update is no longer available for download. They are maybe working on a fix to these problems and have pulled the update.
Battery update firmware is useless... After update i accidentally update all apps (including weather app, the culprit in my case). The battery was draining again. After that i reset the grar, clear phone cache, uninstalled and reinstalled gear apps in phone. Then i install all previous apps,watchfaces, and updates, except the weather app updates. The battery return to normal state....
The battery fix is indeed useless. Reboots and reinstalls don't help. Today took the watch from the charger at 100% at 11.30 am - everything has been turned off (WiFi, NFC, always on display, S Health, Location) except bluetooth and the push notifications over bluetooth, brightness at 3/10. At 3.30 pm battery was at 88%. Before Tizen 3.0 update, I had the similar battery usage (15%) after almost 10 hours on a working day, and I also had S Health on all the time.
I should have stayed on Tizen 2, at least until all major issues were fixed. It used to last an entire working week (I always turn it off for a night) - 5 days on one charge and I would still have something left for a weekend to casually wear it somewhere for a couple hours. Now, everytime I check the watch I do that to see the battery charge left rather than enjoy experience the device provides. Sad.
