# Battery vs Zen Battery

The clearest difference is review sentiment: Zen Battery at 89% against Battery's 29%. Zen Battery also leads on rating (4.7 vs 3.5) and ratings volume (8.1K vs 13). Battery's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (monthly vs every 18 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Battery sells 1 one-off in-app purchase and Zen Battery sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Zen Battery holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Zen Battery has 8.1K ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 29% of Battery's written reviews are positive against 89% of Zen Battery's.

Battery ships an update monthly, Zen Battery every 18 months. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
