# Battery Testing vs Battery Saver

The clearest difference is review sentiment: Battery Saver at 87% against Battery Testing's 23%. Battery Saver also leads on ads (none vs shown) and iOS requirement (11.0 vs 17.0). Battery Testing's advantage is rating (4.5 vs 4.1) and update cadence (fortnightly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase and Battery Saver sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Battery Testing holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 228, so its average is the more settled of the two. Written reviews complicate that: 23% of Battery Testing's written reviews are positive against 87% of Battery Saver'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 Saver every 2 months. The most recent releases landed on October 29, 2026 and October 22, 2026 respectively.
