Verdict
The clearest difference is ads: Smart Solar at none against Battery Level's shown. Smart Solar also leads on update cadence (every 2 months vs every 15 months) and iOS requirement (12.0 vs 15.6). Battery Level's advantage is device support (3 vs 1). On price and in-app purchases there is nothing between them.
