Verdict
The clearest difference is in-app purchases: Battery HD+ at none against Battery Watcher's 1. Battery HD+ also leads on ratings volume (2.7K vs 323). Battery Watcher's advantage is ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price, rating, review sentiment and device support there is nothing between them.
