battery drain on apple watch series 4
Since updating my series 4 watch, the battery drain is much faster. Before the last two OS (currently have 7.3.3 installed) versions I was able to go about 30 hours on a charge. Now, after fully charged it will only last 18-20 hours. I haven't added any apps and have the watch in conservation mode where I can. There hasn't been any damage or water intrusion. I have done all the recommended actions of resetting, un-pairing and re-pairing, etc. to see if there was a software hang-up somewhere. No luck. I'm at a loss. Any rumor of a software issue that is causing this?
