Appalling battery life

[Ray42]

I'm pleased with the look and feel of my new Galaxy Watch4 Classic, but the battery life really is dreadful! Despite the device (and the phone app) predicting that I should get about 36 hours from it, I'm getting about 25 hours tops, and that's with all the health apps and sensors disabled. I spend about 90% of my time within range of my phone and my router - I have mobility problems so I don't leave the house very often. Any suggestions to improve the performance would be welcomed.

I am too experiencing that problem, so I'm anxious to find out any solutions, otherwise the watch will be returned.

I appear to have solved the problem, but I've no idea how I did it!

What happened was I managed with a slip of the stylus to unpair the watch from my phone. I found I couldn't reconnect to the watch without resetting it, so this I did. I then tried to set it up as near as possible to the previous configuration and charged it up. That was 39 hours ago and the watch is still showing 33% available! That's pretty much what I used to get from my old watch, a Galaxy Watch. The only setting that I know I changed was to set the display brightness to Auto.

As I say, I don't know what happened, but it may be worthwhile disconnecting and resetting - you never know!

This is my battery status now - as I said before, I've no idea what I did.

Thanks ray42 I was holding off a full reset, but will do it.
