An iPhone Analytics log may contain battery statistics that are hard to read in the raw .ips file. Device Status⁺ → Tools → Battery Log Analyzer parses supported entries into a report with capacity, cycle count, daily charge range, and usage data when those fields are present.
Find and import a log
- In iPhone Settings → Privacy & Security → Analytics & Improvements, enable Share iPhone Analytics if needed. A new log may take 24–48 hours to appear.
- Open Analytics Data and look for a recent file named like
Analytics-YYYY-MM-DD….ips.ca.synced. - Open the file, use Share → Save to Files, then open Device Status⁺‘s Battery Log Analyzer and tap + to import it. The app also offers an in-app collection guide.
Choose a log with substantial content. Not every iOS version, device, or daily file includes the same records. A blank field in the report means the parser did not find a usable value; it is not zero.
What the report means
The report can show cycle count, nominal charge capacity, Apple’s reported maximum-capacity percentage, charge range, screen-on time, active charging time, and selected electrical or temperature ranges. It also computes a capacity ratio from NominalChargeCapacity ÷ AppleRawMaxCapacity when both numbers are available. The app labels this “Calculated Health”, but it is an interpretation of log fields, not a direct laboratory measurement of remaining battery life. Its 0–100 endurance score combines screen-on time and that ratio; it is an app-specific comparison aid, not an Apple diagnostic grade.
Compare several logs from the same device to understand a trend, and consider usage conditions and missing fields. For service decisions, use Apple’s Battery Health screen or a qualified diagnostic rather than one analytics-derived number. Device Status⁺ keeps imported cases in its local history and offers a shareable summary. For a broader system snapshot, see the Diagnostic Log Analyzer.
