Galaxy watch 4 classic battery life..

Hi all.

Received my 46mm 4 Classic BT today, looks great it really does.

Before I turned it on for the first time I charged it to 100%. I have had it on my wrist now for 2 hours sat in the office and its down to 87%

Now lets look at my old watch which was dubbed as the "Samsung Galaxy Watch" model is SM-R800 BT I had a busy day yesterday and it only discharged to 88% the whole day..

This new one seems to be discharging fast and I have only setup the basics, no always on display or any of the health functions setup..

Does the watch need time to calibrate the battery perhaps, shall I give it chance over the weekend to see if it picks its feet up ?

If this is the rate it discharges then I will be returning it and going back to my SM-R800.

Cheers all

I also charged mine to 100% prior to switching it on and mine dropped to around 70% within an hour or so of first use... I let the watch discharge until it turned off and charged it back up and I get 1d 20h of use out of it (WiFi, GPS and NFC all turned on).


My advice comes from being a UK Samsung phone user.
Current Devices:

Samsung S21 Ultra 5G 256Gb > Model: SM-G998B/DS.
Samsung Galaxy Watch4 Classic > Model: SM-R890NZSAEUA.
Samsung Galaxy Buds2 > Model: SM-R177NZKAEUA.

Samsung One Ui 3.1 / Android 11.

Pretty shocking that, my old device can go nearly 4 days still on a single charge.

Maybe its just how they are now..

The new watches aren't as good for battery, my Galaxy watch lasted 3 days with AOD on and my active 2 lasts 1.5 days with AOD so I don't think the 4 will be any better

Yep. I get about 2 days if I'm lucky. Shame really as you feel you spend more time charging and having it off your wrist than get any enjoyment and benefits of having a smart, expensive watch. Would have thought improvements in battery life rather than a step backwards.

Mine took a good few days to 'learn usage patterns' and to give a battery estimate, but also consider that any new device these days needs a period of time to settle (for whatever reason...my s21U was exactly the same)

I don't seem to have excessive drain like others have but don't have continuous heart rate or blood oxygen on while sleeping, AOD OFF! Dark background, auto brightness

WiFi, nfc, regular heart rate check, health tracking all on plus Google payments, media control, 100's notifications, multiple time checks (!!)

I charge each morning to around 100% and seem to regularly wake up the next morning with around 50% left.

Sticking it on charge when I'm in the shower n stuff just keeps the battery topped up

Oh the other thing that might help is that I got a 'bedtime' schedule on my phone which automatically mirrors on my watch so it turns lots of things off overnight. Nice touch.
