Battery level & charging state (from iOS). Live sensors: accelerometer, gyroscope, magnetometer, barometer. Location readouts with accuracy and altitude (permission required). Bluetooth LE: nearby advertisement info (name/UUID/RSSI). Device specs: dimensions, weight, display resolution, wireless bands, and environmental limits, sourced from Apple’s Tech Specs for each model. What we intentionally don’t do: No diagnostics or hardware health assessments. No battery wear/voltage/cycle count and no time‑remaining estimates. No memory “optimizers” or performance‑boosting claims. Frameworks used: UIKit (UIDevice battery level/state), Foundation (ProcessInfo thermal & Low Power Mode), Core Motion, Core Location, and Core Bluetooth. Privacy: Sensor and network data are shown on‑device only. Location is used solely to display location/accuracy and is not stored or sent anywhere.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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. Both last shipped on October 24, 2026.
