Battery Draining After WatchOS 9.3 Update

I have the 8 and the update that was just about a month or less ago has caused my battery to drain overnight. I have unpaired it, reset it, and factory restore it, turned off all kinds of apps that I thought would cause this but nothing works. Now while sleeping it goes from 80% to around 40% or less from around Midnight to 5 or 6 AM. I cannot figure out what is draining it overnight. During the day it is normal depletion. I might have to go to Apple, which I do not want to do.

There are a lot of suggestions in this 4 page thread. But you only replied to the original poster, so I might guess you haven't read the suggestions. Read the posts and try some of the very good suggestions, which just might help you.

I have an Iwatch series 4. OS system updated to 9.5.2 a few weeks ago and my watch battery started draining fast after the update. Apple support had me unpair and re-pair the watch to the iphone and the issue is still there. They claim it is my watch battery but they checked the battery and it is still within acceptable limits. When I asked tech support if other people were having a battery issue after the update they said no. This is not what I expect from apple tech support when many other people are having the same issue as clearly stated here.

This is not the complaints department.

I refer you to the excellent advice of lobsterghost1 above.

"Read the posts and try some of the very good suggestions, which just might help you."

In other words, start at the beginning of the thread and read the other three pages of posts. There are suggestions, some of which might be useful to you.

I did the unpairing, reset and restore, removed some apps, removed some notifications, not much more I can do. As stated, the watch was fine until the OS update 9.5.2. The battery was lasting over 16 hours prior to the update

(I charge it at night) and it would last over 24 hours on a single charge. Now I'm lucky if I get 10 hours on a single charge.

It was lasting 16 hours? Or 24? Unless you have an Ultra, 16 would be pretty close to Apple's 18 hours. The manufacturer's estimates are usually "under ideal conditions". 24 hours would be an unexpected bonus. 10 hours could be normal depending on what you're doing.

However, if you've checked your battery health and it's above 80%, at this point, I'd suggest you contact Apple and have them run diagnostics.

I normally wear the watch 16 hours a day and charge it overnight when I'm sleeping for 8 hours. If I don't take the watch off at night, the battery would last over 24 hours. That was before the recent update.

Now when I use it for exercise (tennis, bike riding, elliptical, etc.), stand notifications, closing rings, the battery dies much faster, like 10 hours. It used to last much longer prior to the update. It seems I was directed to reset and not restore the phone and watch and see if it runs properly, well that is the very inconvenient time issue. I was hoping an update would not interfere so much with older apple products. But I suppose I am griping too much.

There are 4 pages of people complaining about their batteries after an update. There are two level 10 advisors that don't have the issue. TWO! Anyway, you have suggestions and I thank you for your time.

Please fix this apple

my watch battery went from lasting all day to 4-5 hours after update

this is a software problem

Apple isn't here on this user to user only forum. So they won't see your post, nor respond to it.

Most users are NOT having any battery drain issues. So expecting a fix from Apple for something which isn't happening to most people won't help you.

Have you updated your watch to WatchOS 9.6? If you haven't, you should.

This thread has many suggestions in multiple posts. Which of them have you tried?

My watch is updated to the most recent version

it went from having no battery issues to loosing all battery halfway through the day

nothing else has changed

it used to be at 30% remaining when I went to bed

now it’s dead at 1pm (I wake up at 7:30am)

definitely a software issue

apple fix this please

I’m not upgrading if that’s what you’re trying to force through this “bug”

watch is only 2-years old

not cool….

You have to go directly to apple. Many people have had battery issues after the update but in this forum they say it is only you.

What did Apple say? Did they offer any user remedies or testing?

Apple Watch uses a LOT of battery - Apple Community

Same for me. Reset and all.

is it work for reset ?
