Sudden and extreme battery drain (1% every 5 minutes) - Galaxy Watch 4 46mm LTE

[Members_iG1SX2D]

Hello everyone,

I am having a problem since yesterday with the battery usage on my new GW4.

Yesterday, my Watch 4 classic 46 mm died after 12 hours of extremely light usage.

Today it was better until I talked using LTE. I lost exactly 22 % in 20 minutes of talking. Since then I am losing 1% of battery every 5 minutes. For reference, in 30 minutes (measured every 5 min) it went from 37% down to 32%, and down to 26% in 60 minutes. So we are talking about losing more than 10% per hour!

Battery is optimized, all apps are closed, I rebooted many times and I have it resting on the table with everything turned off except bluetooth.  Connection to my phone (Note 20 Ultra) is ok. I rebooted the phone as well at the same time before I started measuring. I cannot make it stop loosing 1% every 5 mins. Something is completely off. I just wiped the cache as per some user's instructions.

I remember back when I had an android watch I had exactly the same random issues. Went to GW3 and everything was mint. Now I face them again. Unacceptable for its price. It's one week old and I already hate the battery...

51% battery drain in 3hrs...this is unacceptable. I want to return this brick and get a full refund.

Hi!

I have the same problem, 31.10.2021 During the sleep my GW4 46mm LTE lost 60% of battery, and after that, every time I look at watch, battery has loosing 1%. In local support told me to try reset connections on my phone, I reseted my GW4 and connection on my phone, charging GW4 and will look what happen after this procedure...

UPD:

After reseting connections and GW4 all looks ok for now.

i have big battery drain issue with my GW4 46mm LTE,  when I go out without my cell phone, and leave the watch connected via LTE,  it consumes 40-50% of battery in three hours or so. Practically makes LTE useless...

When the watch stays connected to my phone via BT, all is ok. i have the latest firmware...

I hope some update will fix this?!?

I have the 40mm version, with energy saving on, Bluetooth headphones connected + music playing via Spotify, HR measurement every ten minutes, tap to wake on, tilt to wake off, GPS off, LTE on demand I get pretty much exactly 1h20mins from 100% to 0% if I am not connected to wifi or to my phone. That is completely unacceptable and feels like a joke. I mean, sure, it's the smaller version, but come on.. The reception for mobile networks is great everywhere around here, seems like the built in modem goes haywire. I hope software updates fix this as wear OS 3 is pretty new.

EDIT: After some investigation I came to the conclusion that it isn't all Samsungs fault. Spotify is also doing its best to reduce the battery life of the watch as much as possible. It streams the playback progress to all the devices, consuming a huge amount of battery life (because it does so via LTE if WiFi and the phone are not connected). There is no 'go offline' button, so theres nothing we can do about that. If I play back music via mp3 files downloaded to the watch, the battery life still is extremely bad but it adds at least 20 - 30 minutes of playing time. You can vote for the idea here:
