# Lirum Device Info vs Battery Testing

The clearest difference is price: Battery Testing at Free against Lirum Device Info's $299.99. Battery Testing also leads on ratings volume (12K vs 13) and rating (4.5 vs 4.2). Lirum Device Info's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence, device support and iOS requirement there is nothing between them.

Battery Testing is free to download; Lirum Device Info costs $299.99 up front. Battery Testing sells 1 one-off in-app purchase. Lirum Device Info asks for nothing beyond the download.

Battery Testing holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 52% of Lirum Device Info's written reviews are positive against 23% of Battery Testing's, so the app with the better star average is not the one people write more warmly about.

Lirum Device Info ships an update every 4 weeks, Battery Testing fortnightly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
