WatchOS 10 battery life

Yes. iPhone 13 Pro Max and Apple Watch 4. We updated all 4 devices on the same day. Mine didn't start having issues until the last update in OS 9 which I updated to about 2 weeks ago. Most of OS 9 worked perfectly for me. That update caused issues, but it wasn't until I updated to 10 on Friday that I couldn't even get beyond lunch without it dying.

Same with me. Most days since the update, it’s down to 10% battery life by 7pm. Yesterday, it reached 10% by 10:30 AM. Never had an issue before updating to OS 10. Rarely had to charge my watch during the day before the update.

Not sure about this to be honest. Reduction of battery life, yes of course. Dividing it by 2 after an upgrade, not coherent.

Post Hoc Fallacy

Or this proves Apple is managing planned obsolescence...as they did with iphones a few years ago and had to revert with a new os update

Oh, gosh, not that again. Apple did not cause the batteries to degrade. A couple of years back, Apple introduced a function in iOS to throttle the performance of phones that already had seriously degraded batteries. The purpose of this was to prevent the phones from suddenly shutting off, potentially leaving a customer without a phone in an emergency. And they didn't get in trouble for that. What they got in trouble for was not properly informing customers of this.

That feature was never removed. It still exists in iOS 17.

Why is Apple making us all jump through hoops, if the issue is clearly caused by a software update?

Apple, please fix the mess yourself.

Apple is not reading here in this user-to-user forum for feedback or suggestions. You can, however, let them know your thoughts here:

Product Feedback - Apple

I've managed to get a replacement of my AW 5 by Apple for free.

The battery capacity was 75%

What is funny is that now the battery capacity is confirmed at 100%, but the battery is 60% after only 5 hours. And I'm at home with good wifi. Usually it gets worse out of home.

I'll see if it gets better after a few days.

So it turns out that it didn't fix the problem for very long. I ended up chatting with Apple support and they ran remote diagnostics and couldn't find anything wrong. As it's under warranty I've returned it to them asking to be downgraded to watchOS 9 as that worked fine.

FYI, this tip doesn't help at all, at least not for me. I switched to a watch face with only two complications, and no weather functions at all, and my battery usage now is even worse than it was before. In around 8 hours I am down to 40%. Since this is the level I used to see after 15-16 hours, I estimate that the watch is using roughly twice as much power now as it did before watchOS 10. So this the source of the problem, clearly. If anyone has spoken to Apple about this and had any answers from them, I would grateful if you could pass along what you've heard.

As you didn’t have an immediate answer to my two questions I deduce that the user tip didn’t work because you didn’t work through it.

Just to let you know, my brand new watch 5 (with new battery 100% capacity) started full at 8:30 in the morning, and is at 20:20 at 25% left.

This is much below what it should be...

Let's see if the next update fixes something.

Yes, I really hope they fix this soon. I have background app refresh off and this is unexpected. I’ve started looking into other smart watches after I bought this one, bc some need to be charged every other day, I can live with having to charge Apple Watch every day (up to 24-36 hours) but to have to charge it 2-3x in a day to ensure it won’t run out of I have a longer day is really a bother

Any feedback after 10.1 update ?

For me, with brand new battery (100% capacity), from 8am to 7:15, 45% left.

But I'm home, so the watch is its best condition.

Looks like the same as before the update

I have a series 7. Updated this morning and battery was at 72% when i updated to iOS10. 2 hours later it was dead. It normally takes me an hour to full charge the watch. After 2 hours it was at 38%, and 5 minutes later it was at 29%. 25 minutes later it was at 10%. This is unacceptable to say the least. Getting fed up with Apple.

still happening now.10 days later

I'm experiencing the same issue on the Ultra Watch 2. Fully charged at 6:45 am this morning and I'm currently at 27% at 1:09pm (same day).

No workout just teleworking.
