Verdict
The clearest difference is rating: SystemBatteryAnalysis at 4.4 against Yiku's 3.0. SystemBatteryAnalysis also leads on ratings volume (225 vs 4) and update cadence (every 6 days vs fortnightly). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Yiku sells 1 one-off in-app purchase and SystemBatteryAnalysis sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
SystemBatteryAnalysis holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: SystemBatteryAnalysis has 225 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 48% of Yiku's written reviews are positive against 45% of SystemBatteryAnalysis's, so the app with the better star average is not the one people write more warmly about.
Yiku ships an update fortnightly, SystemBatteryAnalysis every 6 days. The most recent releases landed on November 4, 2026 and November 11, 2026 respectively.
