I still have the Pixel Watch 2 and it's much the same, battery barely lasts a day, if even that. I didn't know this going in. I had purchased the Pixel 8 I think it was and saw the watch was heavily discounted if I bundled it in so I did. Will never buy another one. I'm a heavily sleeper and need multiple alarms sometimes to wake up and would often use my watch alarm to supplement my phone. So it became a nightly routine of making sure I didn't forget to charge my watch before bed, lest it dies in the middle of the night.
