watchOS 9 battery drain

I have an apple watch 5. After upgrading to watchOS 9, I am facing a serious battery drain, where a full recharge is not enough for 12h without workout and 1h with a workout? is that a OS issue? or my watchOS battery is not in a good shape? Before the upgrade I was recharging every 24h

Hi here, I have been encountering the exact same problem for 2 weeks but have finally found a way that stops the battery drain for me.

I'm using Apple Watch Ultra but started encountering a serious battery drain issue starting from last week, battery evaporates at a 10% hourly rate on idle state even when my low power mode is on. Some solutions would suggest repairing or factory reset, but none of those actually worked for me. I had to use my AppleCare for an exchange, but the second watch suffers from the same nightmare.


After reading: apple.com/uk/batteries/maximizing-performance/

Disabling Bluetooth on your iPhone increases the battery drain on your Apple Watch. For more power-efficient communication between the devices, keep Bluetooth enabled on iPhone.

I noticed that as long as I keep the bluetooth of my iPhone on, the battery situation will be normal. (now at ~1% per hour instead of 10%)

Personally I feel that there is a problem with WatchOS 9.1 when dealing with the no-bluetooth situation, but I'd suggest to give this a try if you are suffering from the same issue & also have a habit to keep the iPhone bluetooth disabled.

Hope this helps somebody.
