Apple Watch series 5 battery drainage.

i had this problem, here is what i did to fix it.

on your watch go to -> Settings ->General -> Background App Refresh ->

Turn Off:

Compas

Noise

After this change was done, the watch is back to normal. Lasting all day with a little under 50% Battery.

Before this change the battery would be at 50% left with most of the day left. As soon as it gets to 30% it would quickly drain to under 20%. I knew something was wrong.

I will try that. I have the modular face, which I love and always use, same complications as my prior model. Actually my entire watch is set up the same except I have less features on and compass and noise are not even on the watch.

Try resetting your Watch by pressing in the crown and side button until you see the Apple logo, then release both buttons.

Yes my battery drained to 10% in 4 hours!! As much as Apple charges what is the point if you cant wear all day?

Turning off compass and Noise in General>Background AppRefresh

stopped the battery drain for me

I thought 10% was bad i looked and my watch has drained 20%, in just the same amount time. I've reset, hard reset, I have done it all! I hope your issue gets resolved.

Have you tried this

on your watch go to -> Settings ->General -> Background App Refresh ->

Turn Off:

Compas

Noise

I have, I unpaired it as well. I have less usage than I had with my s3 which at this point is pointless and I can’t make it through the day with it. I’m so confused

I actually have every app in app refresh off

I also saw in a video that the type of face you have on the watch affects the battery. Try a really simple face no complications.

if this doesn't work i would try to reset the watch. Unpair and pair back.

Done that multiple times.
