Memory consumption of that level has no noticeable impact on battery life. There are bloated web apps that should be improved for sure, but they also exist with "native" languages. The issue has always been runtime computations, PWAs are perfomant if you keep them low. I wrote myself an ebook and webnovel reader PWA which tracks progress by pixels and percentage amongst other things. There is no noticeable difference between fbreader (native) and this angular app. I get the same amount of drain per hour as I repeatedly verified when I switched.
