Verdict

The call

The clearest difference is review sentiment: PhoneBattery at 58% against Battery Testing's 23%. PhoneBattery also leads on ads (none vs shown). Battery Testing's advantage is ratings volume (12K vs 381) and rating (4.5 vs 4.3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Battery Testing holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 381, so its average is the more settled of the two. Written reviews complicate that: 23% of Battery Testing's written reviews are positive against 58% of PhoneBattery'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, PhoneBattery every 8 days. The most recent releases landed on September 28, 2026 and September 19, 2026 respectively.
