The issue is that battery widget with percentage uses three times more RAM than the normal one! It's like 100 variables extra.
And honestly everything is like that - once you start throwing the kitchen sink in the memory usage goes up loads, and speed goes down. On Bangle.js 2 it's not such an issue with RAM, but even so I'd prefer to keep one version of each app that 'just works' and is efficient (which I can ship with), and then another version that's got all the features added.
