I unpaired and repaired my watch, and I turned off that detect gym equipment setting. My watch is still getting about 4-5 hours of runtime before dying (with no use aside from some notifications). I really hope beta 3 comes out this week and cures it for me. I had great battery life in beta 1.

Try resetting sync data before doing the unpaid process.

That’s the only thing that worked for me.
 
How can I resetting sync data?

In the watch app, General/Reset/Reset Sync Data

Nothing seems to happen, you just have to wait, from what I read.

My watch (series 2) was 2 days battery in OS3, beta 1 took it to about 30% by the end of each day, beta 2 it's going into reserve before the end of the day.

I've just done this reset, and the gym equipment thing, so let's see what happens.

Thank for answer. But I did such a date reset. Unfortunately it did not help. Such as un pair/re pair. I thought it was about resetting fitness data.

Hope to see new beta soon.
 
I don't really understand the battery life with BETA2. While at home on Saturday and Sunday the battery lasted all-day. It was still far worse than normal, it usually lasts two-days but still better than the 6-8 hours I got after updating to BETA2. And this was even with a three hour training session.

But today it's back to the same horrible battery life. It seems when I'm not at home the watch is doing something that completely demolishes the battery. I can't be at work for a full-day without the battery going dead. But as I said, during the weekend while being at home it lasted through a single-day, even with a workout session during the day.

At home were you on Wi-Fi on your iPhone? And at work your on LTE?

Mine drops 10% per hour no matter if I’m on Wi-Fi or LTE. Home or away, the battery life on beta 2 is horrendous for me. I’m hoping beta 3 comes out very soon.
 
I was having similar problems on my series 0, and on reddit someone discovered this and it seems to have fixed the battery issues:

Right after updating to watchOS 4 b2, my battery life was pretty crappy. I was getting maybe 5-6 hours. Did a clean install, didn't seem to help much, battery seemed to still be depleting quickly but I found a new feature setting - Detect Gym Equipment - that was turned on by default. It's in the watch app on the phone under the Workout setting.

Turned that off and battery seems back to normal now, at 87% after 6 hours off the charger.

Update: about 9 hours now off charger and at 75%
Yes!!!
 
Seems my watch stabilized with battery regards. This happened when my workout app crashed while I was trying to run it. The watch rebooted on its own and my battery is at 50% for the last 3 hours.

I was getting 10% drop per hour.

I’m wondering if it was a third party app which was causing my issue. So I have uninstalled all third party apps and will have to wait it out.

I was also too quick to think it was fixed. Last night after trying the reset sync data trick it was pretty good for 3-4 hours.

Today at work it burned through the battery and was dead not long after lunch.

My phone was on and off Wi-fi during the day as the work Wi-fi is quite restricted, so I tend to switch it off every now and then.

Tomorrow I’m either going to remove all 3rd party apps or have a day on airplane mode. Not sure which yet.
 
I think the issue is pipelined process.

After plugging my iPhone into Xcode > Instruments > Activity Monitor....
Whenever I launch/refresh/use certain apps on Apple Watch, pipelined process on iPhone will spike to consume maximum CPU.

This happens with certain 3p apps calling Location Services, but also is triggered by the stock Workout and Maps apps. Other native apps do not seem to be triggering this pipelined process; have tested on several, and I believe all that call Location Services.

(**the atc process also randomly consumes excessive CPU - but unsure what's triggering this**)

I was looking in console at the logs to see if anything stood out but haven’t got as far as you.

I’ve got the outlook app on mine which given it holds my work calendar is pretty active.

I think I’ll remove it for now.
 
I had horrible battery drain on my Series two for three days in a row. It died every day around 7pm when it used to last almost two whole days. I simply shut the watch completely off and turned it back and now my battery life is back to normal. No need to re-pair.

Turning off the gym detect does not work for you?

Didn’t work for me, turning off gym equipment.

My watch rebooted on its own when I was starting the workout app. Then I got great battery life for 4 hours, then back to the battery drain.

I removed all third party apps, uninstalled all third party apps and going to unpair and repair once my battery gets higher as a new watch. Not restoring from backup this time.
 
Took the plunge huh :) yea that’s very good.
yea i did and idk how i seem to be the only one who doesn't have battery issues its not as great at watch os 3.3.2 but its still good for being a beta a lot better then a lot of you guys are claiming its bad
 
battery life sucks over here, i’m in b2 of watchOS4 and it’s just battery hog, turning of gym equipment detection didn’t make difference and it still dies 4-5 hours after removing from charger. i’m going to run some diagnostics and see if i can pinpoint the battery drain.

Have you tweaked any settings on the Apple Watch side on the phone?
