Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Battery Testing ships an update fortnightly, Phone Diagnostics every 2 weeks. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
