Series 4 Battery Drain

iDrummer3 said:
I have a 44mm Series 4 AW LTE+GPS that I purchased from ATT on a next plan and received it launch day. Yesterday around noon my watch died. I thought that maybe the charger had come unplugged and I just connected it to the magnet. I made sure to check it this morning when I woke up and it was 100% around 5:00AM. Around noon I got another low power notification. I haven’t changed any settings and do not have LTE mode currently on. The only difference in the past 2 days is updating my phone to iOS 12.3. Anyone else had issues since updating? Should I call ATT or Apple if it is hardware related and needs replaced?

Same problem here. Wore for 3 hours this morning, 20 min workout, no cellular and I’m at 15%. This is a new issue for me that started this week.
 
I’m currently at 66%. Before the last updates, That is what the charge level would be at around 7-8pm. It’s 2:07pm right now. I’ve been setting at my desk for most of the day.
 
I am also on 5.2 and have seen more drain than I had before that update in the 5.1. Still get 2 days of battery life but it is closer to 10% than it was before. Previously might be around mid 20s %

Have yet to update to 5.2.1 as I hate doing updates when it doesn't add anything.
 
A couple of weeks ago, my S2 (wOS 5.1.3) was having battery issues. By 8AM, I noticed that my AW was below 100%, which was very odd (normally, I don't drop to 99% until 10AM or so), so I started taking data points.

Normally, my usage time is about 15% of the Standby time, but by 8:30AM, it was at 30%. I restarted my AW and iPhone several times and neither worked. Usage time stayed at about 30%.

It wasn't until around lunchtime, that I tried messing with the "Background App Refresh" within the Watch-app on the iphone. There were a bunch of apps that were "on", that probably didn't need to be. So I only kept the few "on" that I felt I needed.

Whichever one I turned off did the trick. I dont' remember which ones I turned off and I wasn't systematic about it.

If you're still having issues, I would try looking at that.

Hmmm, I turned off all background app refresh off and it still drains very quickly.
 
For me, it seems to be related to my usage of the Mail app on the watch.
Just anecdotal of course, but it seems on days when I frequently check my mail from the watch, something gets stuck and keeps my usage stat high, resulting in a trust a battery drain than expected
