Apple Watch Reboots During Runs While Streaming Music via LTE

I have had this happen twice in the last week using two different watches.

First on Sunday using my Series 4 LTE, I was about 40 minutes into a run, using iSmoothRun and streaming Apple Music when the watch just shut down. I restarted it and it showed 10% battery .. I started with the battery at 100%. I rebooted again, and the battery showed 70%. The watch created a LowBatteryLog in the diagnostic logs on the phone. So I thought must be a hardware issue.

Then today, I pulled out my older Series 3 LTE, switched my Verizon service to it, and went on a run again using iSmoothRun and streaming Pandora this time. Again, about 40 minutes or so in, the watch shutdown. I turned it back on, and the battery level was 67%. But again, a LowBatteryLog entry was created.

Both times the run data was lost .. which is the cardinal sin of running watches in my mind .. guess I am going back to my Garmin Fenix 6.

Both watches are running watchOS 7 .. the Series 3 had 7.03, and 7.02 on the Series 4.

This similar scenario happed to me while using Workoutdoors too, so I don't think it is iSmoothRun causing the issue. Seems like the combination of GPS, music streaming via LTE might be causing the watch to inaccurately report the battery level.

I did open a support request with Apple.

Here is the text of the LowBatteryLog from today:

Same issue here. It will reboot and say it has 10% battery left, but when I stick it on the charger it goes back up whatever it was. Has ONLY happened when running and streaming music.
 
Same here, about 30-40 minutes into a jog LTE streaming a podcast I get the 10% power warning. I’m using stock workout app and stock podcast app on a series 3 watch.

Also having issues with random reboots, and worse no exercise battery life. I so regret updating to watch7, its been a disaster for me.
 
This is unfortunate. Sorry to hear you guys dealing with it, but thanks for the heads up. I'm still on Watch os 6. Sounds like I'll be staying there for a while.
 
Odd, I just finished a 70 minute jog while streaming a podcast over LTE, and my battery life is now 48%. Makes no sense why the last 3 jogs had the issue and this one was just like normal (battery drain still higher than normal).

quick update, 50 minute jog today streaming podcast got the 10% battery at the end. Started jog with 83% battery.
 
I get same behavior with my Series 5 and Apple Watch OS 7.0.2. iPhone is 11 Pro Max and OS is 14.1. This happens when I track my activity using the watch iOS activity app along with listening songs on either Tidal or Spotify. Even at home when watching AppleTV+ on the iPhone and listening through my Airpod Pro, the watch reboots. Contacted Apple watch support and they are sending me another replacement watch .. this is the second replacement watch I am receiving for the same issue.. sad thing is this is probably a software issue and the Apple support team is unaware of this issue.
 
The latest in this saga, had a support appointment at the apple store for this issue yesterday. They wiped the watch and we set it up as new. I already restored it from back up twice a week before this and restored the iPhone from back up also a week ago.
Went for a jog last night after the appointment and spending an hour getting my settings back to the way i want it, and guess what.....it happened again at 43 minutes into the jog.
Also watch wouldn’t charge and had a few random reboots too. Back to the store whenever they have an appointment available.

I miss watchOS 6 so much.
 
Getting an appointment is so hard with only few Apple stores open and all appointments booked up .. my wait was around 3 weeks here in Orlando, FL
 
I have this exact issue with my brand new series 5. I wouldn’t even get a battery warning

100% to nothing in minutes. Hardware fault. Replaced the watch and it was fine

upgraded to a 6 now, last 5 had gps issues

Yep two weeks for me to get my second appointment. And now I am getting the rebooting thing again since the last appointment.
Today left for a 2 hour jog at 100% charge, 55 minutes in, the watch just shut off without the low power warning. Wouldn’t turn back on.
It sucked because I needed to call my wife to let her know it was nice out and wanted to go longer but couldn’t as the watch was dead. Would have sucked if I bonked and needed to call her to pick me up.

I has the same issue a few weeks back whilst using Nike Run Club.

About 40 mins into a run whilst streaming music over LTE, the watch rebooted and the Apple logo displayed for around a minute.
However much to my surprise the run stats were not lost and the watch was still recording the run. I’m super careful now though but this bug does suck
 
Checking in; Had my appointment this past saturday, they couldn‘t fix it there so they sent it in. I received a watch back today (I think its a replacement, could be the original, who knows?). I will test it this evening on a jog to see if its working.
 
Been using my Garmin Fenix 6s Pro for runs since my original post. Today I decided to try my AW 4 LTE on a longer run given that WatchOS 7.2 came out recently.

Much to my surprise I completed a 1.5 hour run while streaming Pandora over LTE without a reboot. Also, only used about 40% of the battery.

Encouraging .. hopefully it wasn’t just a fluke.

Fantastic, thanks for posting Bob! I’ve been holding off on upgrading to system 7 until. This bug was resolved. Sounds like we may be there
 
New update;

After receiving my replacement watch, i went on a 40 minute jog, everything seemed okay. Then went on a 50 minute jog, still okay battery drained more than normal. Today went out for a 2 hour jog and IT DID IT AGAIN IT SHUT OFF. Got the 10% battery reserve warning at 69 minutes and watch died at 70 minutes.
I keep explaining to apple that this didn’t happen on watchOS6, that it is not the hardware its a software issue. Off to call apple again. I am done with the Apple Watch back to my Garmin.
 
@Bob190 : thanks for the addendum. i was wondering, if the 7.2 might have a positive effect on the watches battery life and its tooo dim display in very dark surroundings.
soo.. patience i must have ... ;)
 
Well I have given up. Just came back from my 4th Genius appointment and nothing that they can do but send the brand new replacement back to only send me another new replacement that will still have the same issue. Kudos to them for easily replacing a used watch. I keep telling them its a software issue, but their procedure is their procedure, but my patience is my patience and it has all run out.

Unfortunately I am giving up on the Apple Watch and not moving up to a 6 series or 7 next year when it comes out. Stinks because on watchOS5&6 I loved this watch, it was amazing outside of my uses and even more amazing for my specific uses for it.

Sorry to hear that but I can’t say I blame you.
