# Battery Testing vs Reliance Battery

The clearest difference is rating: Battery Testing at 4.5 against Reliance Battery's 3.0. Battery Testing also leads on update cadence (fortnightly vs every 2 months) and ratings volume (12K vs 4). Reliance Battery's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

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

Battery Testing holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 4, so its average is the more settled of the two.

Battery Testing ships an update fortnightly, Reliance Battery every 2 months. The most recent releases landed on September 26, 2026 and July 5, 2026 respectively.
