Ultra 2 and 3 draining battery on Cellular in 24 hours ....Detailed analysis?

[one1]

I'm not looking for help on the issue. I have had Apple watch for a decade and everything is off that I can find. I'm looking to see if there is something like Coconut battery for Watch so I can get a detailed analysis of the battery drain. My suspicion is a background process that I can't see with the lack luster battery graph. Has anyone created an app that can read the battery usage in detail?

I'm not aware of such an app for the AW.

Have you checked background app refresh settings esp 3rd party apps? Maybe disable some of those?

… or disable/remove third-party apps until you discover the culprit(s).

If this is with a watch that’s actually a decade old, then the battery is unquestionably on its very last legs. No battery with that chemistry manufactured a decade ago is functioning as it did when new, and the thousands of cycles a decade-old watch has gone through will have degraded it significantly further. You don’t need to profile phantom background usage any more than you need to have a 90-something-year-old patient with multiple significant symptoms of dementia do an MRI.

Batteries in modern electronic devices are consumables, like spark plugs in a gas-powered car. Modern ones are amazing such that they don’t wear out until other major components do, too, so they’re basically “for the life of the unit” sorts of things.

But smartwatches are emphatically unlike traditional watches, especially mechanical ones. They’re not meant to last more than several years, with a decade being well into “Wow — that’s amazing it lasted so long!” territory.

If the watch has significant sentimental value for you, it’s probably possible to replace the battery. Don’t try to do it yourself; if you had the skills to do this sort of thing, you wouldn’t be asking for help here. It’s an especially fiddly repair, and even those who do it for a living might not be able to ensure it’s fully waterproof (etc.) at the end.

If it doesn’t have sentimental value, it’s guaranteed more economical to simply replace it. Even the cheapest refurbished model you can get from Apple will be far and away more capable and durable than a decade-old watch, no matter how top-of-the-line it was then.

Since this is happening with an Ultra 2 and Ultra 3, it's clearly not a decade old.

I know that you said that you are not looking for help; I know of nothing that can show detailed battery usage on the watch unfortunately. Though you are not looking for help, I'll still list my own watch battery drain troubleshooting on Apple Watch:

1. First try restarting the watch and iPhone and see if that helps.
2. If not, try Watch App / Reset / Reset Sync Data. This used to be more a thing in the past, but sometimes the data that's synced from calendars and contacts gets corrupted and the watch goes into a re-sync loop. This reset wipes the data from the watch and rebuilds it from a new sync.
3. If that still doesn't help, as others have said, try removing third-party apps one at a time to see if that fixes anything.
4. The last thing that I would try is to factory reset and rebuild the watch from scratch, knowing that this will lead to higher battery drain for a few days after it's done.

The only other possibility that I can think of is to turn on Settings / Privacy & Security / Analytics & Improvements and turn on "Share iPhone & Watch Analytics" and then look in the Watch app / General / Diagnostic Logs and see what shows up there - maybe it will show something crashing?

Good luck, I hope that someone has a good answer for you.

The big question is whether your watch is maintaining a bluetooth connection with the phone at all times. If it is, then the cellular is not being actively used and you should not be seeing a huge drain.

If it's not, i.e., you're typically away from the phone and/or the BT connection is turned off, then you should expect a significant battery impact, depending how much the LTE/5G radio is used.

Thank you both. I notice on wifi I can maintain a 3 day battery (Friday evening to Sunday mid day). Once I leave for work Monday morning I've used 10% since it came off the charger Sunday night, and below 40% when I get home.

Sounds like it’s ok then. It’s really meant to be a companion to the phone.

You don't need an app to tell you that the cellular connection is what's causing your battery drain, it's normal.

As has been said the apple watch is meant as a companion to your iPhone and isn't meant to be a standalone device.

I don't even look at it. It's there through the day, lost 60% in 9 hours., That's not "all day battery life" and not normal. My Ultra 2 USED to get all day battery life until the latest watch OS before liquid glass. Now the Ultra 2 and 3 both get bad battery life. Nothing about "companion" is relative to this issue.
