Apple watch battery draining a lot faster all of a sudden

[iphone1027]

I too was having excessive battery drain all of a sudden. I literally would take my watch off the charger (with 100%) and within 5-6 minutes I had 95% left. I rebooted both my watch and iphone; nothing.

So I unpaired my watch and reset it all and re-paired it. That worked. Now when 10 pm comes around (I take the watch off the charger at 5:30 am) I have about 70-75% battery left. I think it was an app that was constantly draining my watch battery.

Since the update my watch is draining faster, even after a reboot.

Put my watch on this morning at 6:30am to drop my daughter off at school, it's now 8:18am and my watch was at 79%, so there is something going on with this update. I could go 6 hours to 79% prior to the update.

I had a similar problem since the last update, but a reboot of both the iPhone and the Watch fixed the issue for me.

Before the reboot, my watch was fully drained after 9 hours. Now it is back to normal at about 60-70% after 9 hours (including 90 minute workout).

I did a couple reboots of both the watch and phone before going out to dinner tonight and everything seems to be back to normal.

This may be a little over the top, but I unpaired my Apple Watch, reinstalled iOS 9.3.2 via iTunes, then restored my iPhone 6s Plus from my iCloud backup. Once everything was back, I re-paired my Apple Watch. I've been wearing it for almost 2 hours and still at 100%. I updated the phone and watch via software updates a few days ago. Just wanted to start new again. From what I understand a restore via iCloud doesn't preserve old settings.

When I had the 38mm it would be 100% around 11pm then around 5-7am it would have around 39% called Apple and said it was normal.
No notifications

mine is around 60% by the time I leave work at like 3pm (student part time job). I do nothing but check the time every once in a while.

I already got it checked by Apple and they said my battery is in perfect almost brand new condition (got it in may of last year). they did say there was an unusual amount of apps crashing so I was told to set it up as new but that didn't really help. it is still dead by the end of the day without doing much with it

The new update should fix it.
My apps were crashing and somehow Apple got it fixed.

Had my watch for a year and never had battery drain problems until I started using Apple Pay on my watch past couple of weeks. All this time I used it early morning to late evening and normally have 40-50% left. But three times now since using Apple Pay it has gone into power save mode late afternoon or early evening of that day. Is there any known connection? I have rebooted phone and watch and in fact wiped and restored watch from backup.

Had same problem. Rebooted watch and back to normal. Good luck.

What do you mean by reboot? Hard reset or just turning off and on?

My sports watch has done this a few times. I have rebooted it and it fixed the issue for weeks at a time. I've had my sports since launch.

My battery was fine for a year and a half and then suddenly started draining very fast. I tried everything, rebooted, etc. No change. I then went thru every app, turned off notifications on all except the dozen apps I use. I also deleted all apps I don’t use at all. After that, the battery drain went back to normal. I don’t know exactly what did it, but it drains very slowly now, leaving me with 60% by the time I go to bed.

Nobody has mentioned whether the iPhone with which the watch is paired is on or off when the battery is draining. If the iPhone is turned off and the watch is operating on WiFi or LTE, the battery will drain very quickly. The control panel will show (upper left) if the watch is connected to the phone by BlueTooth (green rectangle) or if it is on WiFi (blue arches) or cellular (green dots).
