# Battery Testing vs Phone Diagnostics

The clearest difference is rating: Battery Testing at 4.5 against Phone Diagnostics's 3.8. Battery Testing also leads on ratings volume (12K vs 86). Phone Diagnostics's advantage is review sentiment (63% vs 23%) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase and Phone Diagnostics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Battery Testing holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 86, so its average is the more settled of the two. Written reviews complicate that: 23% of Battery Testing's written reviews are positive against 63% of Phone Diagnostics's, so the app with the better star average is not the one people write more warmly about.

Battery Testing ships an update fortnightly, Phone Diagnostics every 2 weeks. The most recent releases landed on September 24, 2026 and August 29, 2026 respectively.
