That is seriously ridiculous. Series 7 watches are basically the same hardware, but Apple won't let them save battery life by taking less frequent heart rate readings? Shameful...

I cannot believe they are keeping the battery saving updates from my Series 7 watch I just bought months ago. This is one of the most ridiculous things I’ve seen this company do in a long time. There is no excuse for this.

Can’t wait to see how much battery life has been improved. The battery life on Apple Watch Ultra is already amazing as is. ??

It finally completed and I got another stand hour in. I still stand by what I said earlier, but if I were to give one suggestion on how to update the watch (other than having rest days or banking move calories for other days or specifically opting out of the monthly challenges) it's make software updates easier and allow us to wear the watch while the update process is happening.
