What’s Eating My Battery

Hi all,

In the last few days something has begun to devour my battery. 100% charge last night, 36% just now and I’ve done nothing with it. I think I might know the app causing the problem but other than force-quitting it I’m not left with proof absent battery life goes back to normal.

Am I missing some hidden place that has this information?

Only way to know is to try it with out any apps to see if it is hardware or software.

Before you do anything have you rebooted your watch lately?
 
I have rebooted although I wasn’t aware I was buying a device running on Win95 that such would be required.

It went 100 > 0 a couple of nights ago and it did it in roughly 4 hours so something is chewing it up good. Today it was charged over night and was down to 36% by the time of this thread, so not even 6 hours.

I’ll be running tonight so I guess it’s good I still have my Fenix.

Every tech device just about ever can have some issues that require a restart to flush out..

But, do you have Outlook installed by chance? I was having battery issues on my old Series 3 a few months back. I removed Outlook and the issue resolved itself.

It’s still chewing on the battery. Probably be dead in a couple of hours. I’ve pulled a couple of recent installs to see what happens.

I don’t really accept rebooting as a solution any more. We need to get beyond that. Technology is too ingrained in our world for that to be acceptable. When CarPlay fails, and it fails every single IOS update, the solution is to restart the car.

FFS, NO!

Anyways, don’t want that fight. I was just hoping for a better solution that to uninstall/reinstall apps.
 
For me, it was the Pillow wakeup alarm. After turning that off (changed to autodetect sleep), hey Siri, and putting the watch into Theatre mode when I go to bed, battery only drops ~8-10% overnight (instead of 50%).

What solution were you looking for? The battery dropping really fast is not a widespread issue so it must be something specific with the watch. If you have already attempted restarting it then it must be one of the apps unless there is a deeper hardware issue.

I had that problem with my AW3. Found out that the cellular feature had quit and it was constantly searching for a signal. Didn't even realize it until I accidentally left home without my phone and my watch would not connect.
 
It could be caused by your battery's mentally challenged brother, Arnie, and its morbidly obese mother.

Mostly I was hoping for some kind of usage by app data that I hadn’t found. Guess I can’t have what isn’t there.

What I always suggest doing is a process of elimination by deleting any third-party apps one by one to see what might be causing the drain.

Of course there is always the option of forcing a hard reset by holding down the digital crown and power button for about 10 seconds.
 
I turned off activity monitoring in the watch and that helped battery life significantly. My watch (both a Series 4 and the Series 2 before it) can go about two full days on a charge.
My phone is doing activity tracing on its own. Don’t need the watch to do it too. The only “downside” is that you can’t use the activity rings. But I don’t really care.
 
My series 4 started doing the same thing a couple of days ago and I tried everything to no avail. I finally did a reset which is a pain but everything back to normal.
 
Have you also disabled background app refresh? That eats up battery on both iPhone and Apple Watch.
