# Battery Testing vs Battery Tracker BTR

The clearest difference is rating: Battery Testing at 4.5 against Battery Tracker BTR's 2.9. Battery Testing also leads on ratings volume (12K vs 21) and update cadence (fortnightly vs every 2 months). Battery Tracker BTR's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase. Battery Tracker BTR asks for nothing beyond the download.

Battery Testing holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 23% of Battery Testing's written reviews are positive against 26% of Battery Tracker BTR's, so the app with the better star average is not the one people write more warmly about.

Battery Testing ships an update fortnightly, Battery Tracker BTR every 2 months. The most recent releases landed on September 24, 2026 and June 3, 2026 respectively.
