I bought an Acer Aspire Lite 15 (AL15-72P) in February 2026, and its battery report now shows a maximum full-charge capacity of only 79% of the original design capacity. Is that amount of battery wear normal after roughly seven months, or could there be a problem with the battery or charging habits?

A 21% capacity drop in about seven months seems higher than expected, although actual wear depends heavily on usage, heat, charging patterns, and the number of full charge cycles. Check for apps running heavily in the background, excessive heat, and frequent operation while plugged in. If the capacity continues falling quickly, it may be worth using the warranty.
The most reliable way to check is with Windows' built-in report. Open Command Prompt and run `powercfg /batteryreport`, then open the generated `battery-report.html` file. Compare the design capacity with the full-charge capacity and look for the battery's cycle count or recent capacity history. A single percentage reading can sometimes be affected by calibration, so the trend over several reports is more useful.
I generated the report with `powercfg /batteryreport`, but this particular report doesn't show a cycle count. I'll check the capacity history and keep monitoring whether the percentage continues to drop.
