You people do realize that you can use the Plex server without using the Plex apps right? I pretty much exclusively use Infuse to interface with my Plex server and have none of the issues I see mentioned here.

I’ve been running this for my whole family and friends for years at this point. Way better than any browser based solution.

The Apple Watch can easily last over 24 hours if you only use it as a watch and nothing else. The 18 hour estimate Apple provides is if you use all the features throughout the day such as exercise tracking, notifications, quick replying to messages, etc. If anything the 18 hour number is under selling the battery life.
