Verdict
The clearest difference is rating: Battery Watcher at 4.5 against Battery & Device Infomation's 1.0. Battery Watcher also leads on update cadence (fortnightly vs every 6 months) and ratings volume (340 vs 1). Battery & Device Infomation's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 18.6). On price, ads and device support there is nothing between them.
