Has anyone else noticed the battery is going down a good bit faster? My Series 4 has lost 18% life in just 3 hours since upgrading. No apps are running. I did activate the ECG. I am hoping it’s a fluke.

Mine is draining fast as well. Try restarting it, that’s worked for me in the past.

We get one of those posts every time there's an update to iOS or one of its derivatives. It's normal for battery life to suffer for the fist day or two after an update.

Definitely, It was fully charged overnight and by 8pm tonight after normal use it was completely dead. Series 4. Thats never happened in its short life before. Not good.

Could be an update gone bad for you. It happens.

Also I would like to give a reminder that the battery usage on the iwatch varies greatly depending on what you do with it. How many texts messages you get, exercising, phone calls, movement etc

It seemed that my S4 was draining quicker since the update a couple of days ago. I thought maybe I was imagining things and didn’t worry about it.

I charged it to 100% before going to bed last night and wore it overnight for the sleep tracker as usual. After I got up and had coffee, I checked the battery percentage and it was down to 41%. This hasn’t happened since I got the watch.

The only additional thing running since the update is the ecg app. I’ve restarted and re-paired to my Max. Hoping everything stabilizes soon.

I have great battery life with 5.1.2. Try turning it off and back on or even a hard reset.

Here’s a couple of things to try to troubleshoot.

Try a simple dark face with no complications, like the ‘color’ face set to black.

Try turnong off the ‘raise to wake’ setting (it’s called something else in settings)

If either/both of those help much, it’s probably not the OS.

I have "Raise to Speak" for Siri turned off. Other than that I have everything else turned on (including fall detection), and I haven't noticed any change in battery life.

I’m finding battery to be good on my new S4 44mm, it’s been off the charger since 6:45am and it’s now 4:20pm with 83% battery left, I’ve used it to tell the time, notifications, reply to a few texts and a bit of general messing with it (settings etc) plus some walking tracking, I don’t think that’s too bad at all.

Adam.

I have awful battery on my S4 since 5.1.2 and 12.1.1 released because the watch suddenly won’t hold a connection via BT to my iPhone XS Max. I’ve had the phone in my pocket with the watch on my wrist where the watch defaults to WiFi or cellular draining the battery, and unlocking the phone to use immediately reconnects then. It’s driving me nuts at this point since it doesn’t seem widespread. I’ve set my phone up as new, restored my watch to no avail.

I usually get about 2 days of battery on my S4. Except one night where I went to bed probably around 90% and woke up with it almost dead. Not sure what was going on there and it took a reboot to fix the draining issue. I really wish the OS would notice such issues and self correct things somehow as it is no fun waking up to a dead battery like that. Also wish the watch would tell you what is hitting the battery the way the phone can tell you what app is consuming things.
