# SystemBatteryAnalysis vs 长卷

The clearest difference is review sentiment: 长卷 at 100% against SystemBatteryAnalysis's 45%. 长卷 also leads on rating (5.0 vs 4.4) and in-app purchases (none vs 3). SystemBatteryAnalysis's advantage is ratings volume (205 vs 2) and iOS requirement (16.1 vs 27.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. SystemBatteryAnalysis sells 3 one-off in-app purchases. 长卷 asks for nothing beyond the download.

长卷 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: SystemBatteryAnalysis has 205 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 45% of SystemBatteryAnalysis's written reviews are positive against 100% of 长卷's.

SystemBatteryAnalysis ships an update every 6 days, 长卷 every 4 days. The most recent releases landed on October 28, 2026 and October 29, 2026 respectively.
