Battery drain

[Fatih]

Hi is there anyone know why the battery on Samsung watch 4 battery drain so fast? Last night I charged until full and when I woke up today it left with 70%. Now I'm wearing it for work only just 3 hour the battery goes to 18%. It's crazy how fast it drain. I'm wearing this watch only for 3days and I didn't like it already. Other smart watch have better battery life.

I get this from time to time with my galaxy watch 4 classic. For no apparent reason on a random day the battery will drain like crazy. I find doing a hard reboot (press and hold both side buttons until watch turns off and reboots) drain what battery is left and then charge to full seems to help.

Same. I also installed latest update.

I also did the same thing once I've got the watch. Installed latest update and charged everything, but the battery last not even a day. Is it because mine watch 4 40mm version?

it doesn't matter what version watch you had as long as you did what I commented earlier you be fine.
not abit of patients, use watch or phone, us it untill it fully em that you can't switch back on, then fully charge it. do that few time then it good to go,

Used to happen with my original GW - turned out to be Bluetooth connection ramping up power and draining. Rebooting watch and handset resolved it.

I've done it several times. Off WiFi and Bluetooth, and turn off the watch while charging. But still same, wear it around an hour after turn it on and the battery down by 25% already.
